The yellow powder might be plutonium [25Sep11] - 0 views

  • About the previous post http://fukushima-diary.com/2011/09/news-japan-after-the-typhoon/ I received a message from a reader of this blog. It was to suggest the yellow powder could be plutonium. Here is the explanation. http://sti.srs.gov/fulltext/ms2002705/ms2002705.html source for text below
  • Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor. The physical properties of plutonium metal are summarized in Table 1.
  • Only two plutonium isotopes have commercial and military applications. Plutonium-238, which is made in nuclear reactors from neptunium-237, is used to make compact thermoelectric generators; plutonium-239 is used for nuclear weapons and for energy; plutonium-241, although fissile, (see next paragraph) is impractical both as a nuclear fuel and a material for nuclear warheads. Some of the reasons are far higher cost , shorter half-life, and higher radioactivity than plutonium-239. Isotopes of plutonium with mass numbers 240 through 242 are made along with plutonium-239 in nuclear reactors, but they are contaminants with no commercial applications. In this fact sheet we focus on civilian and military plutonium (which are interchangeable in practice–see Table 5), which consist mainly of plutonium-239 mixed with varying amounts of other isotopes, notably plutonium-240, -241, and -242.

  • Plutonium belongs to the class of elements called transuranic elements whose atomic number is higher than 92, the atomic number of uranium. Essentially all transuranic materials in existence are manmade. The atomic number of plutonium is 94. Plutonium has 15 isotopes with mass numbers ranging from 232 to 246. Isotopes of the same element have the same number of protons in their nuclei but differ by the number of neutrons. Since the chemical characteristics of an element are governed by the number of protons in the nucleus, which equals the number of electrons when the atom is electrically neutral (the usual elemental form at room temperature), all isotopes have nearly the same chemical characteristics. This means that in most cases it is very difficult to separate isotopes from each other by chemical techniques.
  • Plutonium-239 and plutonium-241 are fissile materials. This means that they can be split by both slow (ideally zero-energy) and fast neutrons into two new nuclei (with the concomitant release of energy) and more neutrons. Each fission of plutonium-239 resulting from a slow neutron absorption results in the production of a little more than two neutrons on the average. If at least one of these neutrons, on average, splits another plutonium nucleus, a sustained chain reaction is achieved.
  • The even isotopes, plutonium-238, -240, and -242 are not fissile but yet are fissionable–that is, they can only be split by high energy neutrons. Generally, fissionable but non-fissile isotopes cannot sustain chain reactions; plutonium-240 is an exception to that rule. The minimum amount of material necessary to sustain a chain reaction is called the critical mass. A supercritical mass is bigger than a critical mass, and is capable of achieving a growing chain reaction where the amount of energy released increases with time.
  • The amount of material necessary to achieve a critical mass depends on the geometry and the density of the material, among other factors. The critical mass of a bare sphere of plutonium-239 metal is about 10 kilograms. It can be considerably lowered in various ways. The amount of plutonium used in fission weapons is in the 3 to 5 kilograms range. According to a recent Natural Resources Defense Council report (1), nuclear weapons with a destructive power of 1 kiloton can be built with as little as 1 kilogram of weapon grade plutonium(2). The smallest theoretical critical mass of plutonium-239 is only a few hundred grams.
  • In contrast to nuclear weapons, nuclear reactors are designed to release energy in a sustained fashion over a long period of time. This means that the chain reaction must be controlled–that is, the number of neutrons produced needs to equal the number of neutrons absorbed. This balance is achieved by ensuring that each fission produces exactly one other fission. All isotopes of plutonium are radioactive, but they have widely varying half-lives. The half-life is the time it takes for half the atoms of an element to decay. For instance, plutonium-239 has a half-life of 24, 110 years while plutonium-241 has a half-life of 14.4 years. The various isotopes also have different principal decay modes. The isotopes present in commercial or military plutonium-239 are plutonium-240, -241, and -242. Table 2 shows a summary of the radiological properties of five plutonium isotopes. The isotopes of plutonium that are relevant to the nuclear and commercial industries decay by the emission of alpha particles, beta particles, or spontaneous fission. Gamma radiation, which is penetrating electromagnetic radiation, is often associated with alpha and beta decays.
  • Table 3 describes the chemical properties of plutonium in air. These properties are important because they affect the safety of storage and of operation during processing of plutonium. The oxidation of plutonium represents a health hazard since the resulting stable compound, plutonium dioxide is in particulate form that can be easily inhaled. It tends to stay in the lungs for long periods, and is also transported to other parts of the body. Ingestion of plutonium is considerably less dangerous since very little is absorbed while the rest passes through the digestive system.
  • Plutonium-239 is formed in both civilian and military reactors from uranium-238. The subsequent absorption of a neutron by plutonium-239 results in the formation of plutonium-240. Absorption of another neutron by plutonium-240 yields plutonium-241. The higher isotopes are formed in the same way. Since plutonium-239 is the first in a string of plutonium isotopes created from uranium-238 in a reactor, the longer a sample of uranium-238 is irradiated, the greater the percentage of heavier isotopes. Plutonium must be chemically separated from the fission products and remaining uranium in the irradiated reactor fuel. This chemical separation is called reprocessing. Fuel in power reactors is irradiated for longer periods at higher power levels, called high “burn-up”, because it is fuel irradiation that generates the heat required for power production. If the goal is production of plutonium for military purposes then the “burn-up” is kept low so that the plutonium-239 produced is as pure as possible, that is, the formationo of the higher isotopes, particularly plutonium-240, is kept to a minimum. Plutonium has been classified into grades by the US DOE (Department of Energy) as shown in Table 5.
  • It is important to remember that this classification of plutonium according to grades is somewhat arbitrary. For example, although “fuel grade” and “reactor grade” are less suitable as weapons material than “weapon grade” plutonium, they can also be made into a nuclear weapon, although the yields are less predictable because of unwanted neutrons from spontaneous fission. The ability of countries to build nuclear arsenals from reactor grade plutonium is not just a theoretical construct. It is a proven fact. During a June 27, 1994 press conference, Secretary of Energy Hazel O’Leary revealed that in 1962 the United States conducted a successful test with “reactor grade” plutonium. All grades of plutonium can be used as weapons of radiological warfare which involve weapons that disperse radioactivity without a nuclear explosion.

Obama's Gold - 94.6% Pure, Bomb Grade Plutonium [09Aug12] - 0 views

  •  President Obama asked Duke Power Corporation in the States to test run some plutonium fuel rods (MOX) in three of their reactors. The physicists said No; but, the head boss of Duke Power said “Yes.” Obama’s test run failed miserably.
  • As a result, the country very nearly lost the state of South Carolina. Those deadly  Plutonium cores were jerked out of those three big Duke Power reactors so fast it would make your head spin. Undaunted, unbowed and too ignorant to be afraid, the President of the United  States asked the President of a Japanese utility, the Tokyo Electric Power Company (TEPCO,) to run the “test” of the Plutonium fuel. Now, what are you going to do when the President of the US asks you for a favor? The test was slated immediately for the MOX fuel rods, of course. That is 21,000 lbs of 94.6% pure bomb grade Plutonium 239 (Pu 239) down blended and mixed with Uranium to form MOX 6% Pu 239 nuclear fuel rods.
  • Here’s what happened, perhaps as a result of President Obama’s political dabbling  in real life-or-death physics. This stuff gets real serious real fast.

  • Five hundred eighteen days into the continuous reactor meltdowns and global dispersion of reactor cores; it’s a direct choice for “Gruesome Death” made by the pro-nukers. The deed is done and cannot be reversed. MOX stands for Mixed Oxide Fuel. The very poisonous bomb grade Pu 239 is taken from Hydrogen Bombs and mixed with Uranium to form pellets for fuel rods for nuclear  reactors. The fuel rods are about five (5) meters or 16 ft long and as big around as a person’s thumb. Pu 239 is very hard for bomb makers to work with and tends to go off by itself, which makes for a really bad day. The manufacturing of Hydrogen Bombs is a very nasty business in any country. Putting extra Pu 239 in nuclear reactors to boil water for steam is insane. LETHAL DOSES How many Lethal Doses of radiation from radioactive particles are in our air just from Fukushima Daiichi’s trashed reactors? As of Jun 29, 2012 Dr. Paolo Scampa, a noted physicist stated: “… [about Fukushima reactors exploding]  … occasioning a prodigious explosion of radioactivity and radiotoxicity which over time, is several times the amount needed to kill by internal contamination the whole human race.” - Dr Paolo Scampa, PhD., Nuclear Physicist.

Secret US-Israeli Nuke Weapons Transfers Led To Fukushima Blasts [03Oct11] - 0 views

  • Sixteen tons and what you get is a nuclear catastrophe. The explosions that rocked the Fukushima No.1 nuclear plant were more powerful than the combustion of hydrogen gas, as claimed by the Tokyo Electric Power Company. The actual cause of the blasts, according to intelligence sources in Washington, was nuclear fission of. warhead cores illegally taken from America's sole nuclear-weapons assembly facility. Evaporation in the cooling pools used for spent fuel rods led to the detonation of stored weapons-grade plutonium and uranium.   The facts about clandestine American and Israeli support for Japan's nuclear armament are being suppressed in the biggest official cover-up in recent history. The timeline of events indicates the theft from America's strategic arsenal was authorized at the highest level under a three-way deal between the Bush-Cheney team, Prime Minister Shinzo Abe and Elhud Olmert's government in Tel Aviv.
  • Tokyo's Strangelove   In early 2007, Vice President Dick Cheney flew to Tokyo with his closest aides. Newspaper editorials noted the secrecy surrounding his visit - no press conferences, no handshakes with ordinary folks and, as diplomatic cables suggest, no briefing for U.S. Embassy staffers in Tokyo.   Cheney snubbed Defense Minister Fumio Kyuma, who was shut out of confidential talks. The pretext was his criticism of President George Bush for claiming Iraq possessed weapons of mass destruction. The more immediate concern was that the defense minister might disclose bilateral secrets to the Pentagon. The Joint Chiefs of Staff were sure to oppose White House approval of Japan's nuclear program.
  • Abe has wide knowledge of esoteric technologies. His first job in the early 1980s was as a manager at Kobe Steel. One of the researchers there was astrophysicist Hideo Murai, who adapted Soviet electromagnetic technology to "cold mold" steel. Murai later became chief scientist for the Aum Shinrikyo sect, which recruited Soviet weapons technicians under the program initiated by Abe's father. After entering government service, Abe was posted to the U.S. branch of JETRO (Japan External Trade Organization). Its New York offices hosted computers used to crack databases at the Pentagon and major defense contractors to pilfer advanced technology. The hacker team was led by Tokyo University's top gamer, who had been recruited into Aum.   After the Tokyo subway gassing in 1995, Abe distanced himself from his father's Frankenstein cult with a publics-relations campaign. Fast forward a dozen years and Abe is at Camp David. After the successful talks with Bush, Abe flew to India to sell Cheney's quadrilateral pact to a Delhi skeptical about a new Cold War. Presumably, Cheney fulfilled his end of the deal. Soon thereafter Hurricane Katrina struck, wiping away the Abe visit from the public memory.

  • Since the Liberal Democratic Party selected him as prime minister in September 2006, the hawkish Abe repeatedly called for Japan to move beyond the postwar formula of a strictly defensive posture and non-nuclear principles. Advocacy of a nuclear-armed Japan arose from his family tradition. His grandfather Nobusuke Kishi nurtured the wartime atomic bomb project and, as postwar prime minister, enacted the civilian nuclear program. His father Shintaro Abe, a former foreign minister, had played the Russian card in the 1980s, sponsoring the Russo-Japan College, run by the Aum Shinrikyo sect (a front for foreign intelligence), to recruit weapons scientists from a collapsing Soviet Union.   The chief obstacle to American acceptance of a nuclear-armed Japan was the Pentagon, where Pearl Harbor and Hiroshima remain as iconic symbols justifying American military supremacy.The only feasible channel for bilateral transfers then was through the civilian-run Department of Energy (DoE), which supervises the production of nuclear weapons.
  • Camp David Go-Ahead   The deal was sealed on Abe's subsequent visit to Washington. Wary of the eavesdropping that led to Richard Nixon's fall from grace, Bush preferred the privacy afforded at Camp David. There, in a rustic lodge on April 27, Bush and Abe huddled for 45 minutes. What transpired has never been revealed, not even in vague outline.   As his Russian card suggested, Abe was shopping for enriched uranium. At 99.9 percent purity, American-made uranium and plutonium is the world's finest nuclear material. The lack of mineral contaminants means that it cannot be traced back to its origin. In contrast, material from Chinese and Russian labs can be identified by impurities introduced during the enrichment process.
  • The flow of coolant water into the storage pools ceased, quickening evaporation. Fission of the overheated cores led to blasts and mushroom-clouds. Residents in mountaintop Iitate village overlooking the seaside plant saw plumes of smoke and could "taste the metal" in their throats.   Guilty as Charged   The Tohoku earthquake and tsunami were powerful enough to damage Fukushima No.1. The natural disaster, however, was vastly amplified by two external factors: release of the Stuxnet virus, which shut down control systems in the critical 20 minutes prior to the tsunami; and presence of weapons-grade nuclear materials that devastated the nuclear facility and contaminated the entire region.   Of the three parties involved, which bears the greatest guilt? All three are guilty of mass murder, injury and destruction of property on a regional scale, and as such are liable for criminal prosecution and damages under international law and in each respective jurisdiction.
  • An unannounced reason for Cheney's visit was to promote a quadrilateral alliance in the Asia-Pacific region. The four cornerstones - the US, Japan, Australia and India - were being called on to contain and confront China and its allies North Korea and Russia.. From a Japanese perspective, this grand alliance was flawed by asymmetry: The three adversaries were nuclear powers, while the U.S. was the only one in the Quad group.   To further his own nuclear ambitions, Abe was playing the Russian card. As mentioned in a U.S. Embassy cable (dated 9/22), the Yomiuri Shimbun gave top play to this challenge to the White House : "It was learned yesterday that the government and domestic utility companies have entered final talks with Russia in order to relegate uranium enrichment for use at nuclear power facilities to Atomprom, the state-owned nuclear monopoly." If Washington refused to accept a nuclear-armed Japan, Tokyo would turn to Moscow.
  • Throughout the Pantex caper, from the data theft to smuggling operation, Bush and Cheney's point man for nuclear issues was DoE Deputy Director Clay Sell, a lawyer born in Amarillo and former aide to Panhandle district Congressman Mac Thornberry. Sell served on the Bush-Cheney transition team and became the top adviser to the President on nuclear issues. At DoE, Sell was directly in charge of the U.S. nuclear weapons complex, which includes 17 national laboratories and the Pantex plant. (Another alarm bell: Sell was also staff director for the Senate Energy subcommittee under the late Sen. Ted Stevens of Alaska, who died in a 2010 plane crash.)   An Israeli Double-Cross   The nuclear shipments to Japan required a third-party cutout for plausible deniability by the White House. Israel acted less like an agent and more like a broker in demanding additional payment from Tokyo, according to intelligence sources. Adding injury to insult, the Israelis skimmed off the newer warhead cores for their own arsenal and delivered older ones. Since deteriorated cores require enrichment, the Japanese were furious and demanded a refund, which the Israelis refused. Tokyo had no recourse since by late 2008 principals Abe had resigned the previous autumn and Bush was a lame duck.
  • The Japanese nuclear developers, under the Ministry of Economy, Trade and Industry, had no choice but to enrich the uranium cores at Fukushima No.1, a location remote enough to evade detection by nonproliferation inspectors. Hitachi and GE had developed a laser extraction process for plutonium, which requires vast amounts of electrical power. This meant one reactor had to make unscheduled runs, as was the case when the March earthquake struck.   Tokyo dealt a slap on the wrist to Tel Aviv by backing Palestinian rights at the UN. Not to be bullied, the Israeli secret service launched the Stuxnet virus against Japan's nuclear facilities.   Firewalls kept Stuxnet at bay until the Tohoku earthquake. The seismic activity felled an electricity tower behind Reactor 6. The power cut disrupted the control system, momentarily taking down the firewall. As the computer came online again, Stuxnet infiltrated to shut down the back-up generators. During the 20-minute interval between quake and tsunami, the pumps and valves at Fukushima No.1 were immobilized, exposing the turbine rooms to flood damage.
  • The Texas Job   BWXT Pantex, America's nuclear warhead facility, sprawls over 16,000 acres of the Texas Panhandle outside Amarillo. Run by the DoE and Babcock & Wilson, the site also serves as a storage facility for warheads past their expiration date. The 1989 shutdown of Rocky Flats, under community pressure in Colorado, forced the removal of those nuclear stockpiles to Pantex. Security clearances are required to enter since it is an obvious target for would-be nuclear thieves.   In June 2004, a server at the Albuquerque office of the National Nuclear Security System was hacked. Personal information and security-clearance data for 11 federal employees and 177 contractors at Pantex were lifted. NNSA did not inform Energy Secretary Samuel Bodman or his deputy Clay Sell until three months after the security breach, indicating investigators suspected an inside job.
  • The White House, specifically Bush, Cheney and their co-conspirators in the DoE, hold responsibility for ordering the illegal removal and shipment of warheads without safeguards.   The state of Israel is implicated in theft from U.S. strategic stockpiles, fraud and extortion against the Japanese government, and a computer attack against critical infrastructure with deadly consequences, tantamount to an act of war.   Prime Minister Abe and his Economy Ministry sourced weapons-grade nuclear material in violation of constitutional law and in reckless disregard of the risks of unregulated storage, enrichment and extraction. Had Abe not requested enriched uranium and plutonium in the first place, the other parties would not now be implicated. Japan, thus, bears the onus of the crime.
  • The International Criminal Court has sufficient grounds for taking up a case that involves the health of millions of people in Japan, Canada, the United States, Russia, the Koreas, Mongolia, China and possibly the entire Northern Hemisphere. The Fukushima disaster is more than an human-rights charge against a petty dictator, it is a crime against humanity on par with the indictments at the Nuremberg and Tokyo tribunals. Failure to prosecute is complicity.   If there is a silver lining to every dark cloud, it's that the Tohoku earthquake and tsunami saved the world from even greater folly by halting the drive to World War III.

American Energy Fields - Three Projects in Early Stage Uranium Exploration [08Jul11] - 0 views

  • American Energy Fields, Inc. (OTCBB:AEFI), formerly Sienna Resources, Inc. is a uranium exploration and development company based in Arizona. Their focus is uranium deposits in the United States. The Company’s three main projects (in which they have sole interest) are  the Coso and Blythe  projects in California, and Artillery Peak project in Arizona. All three properties have been previously explored and developed, and are currently in early exploration stages.  A 43-101 technical report for the Artillery Peak project is available for review on American Energy Field’s website. What we like about American Energy Fields, Inc: Over 9.2 million pounds U3O8 historic resources with 2.8 million pounds 43-101 verified More than $25 million in development work, by past operators, has been spent on AEFI’s current projects Committed to near term production of low cost U.S. Uranium
  • The Artillery Peak property consists of 1,777 acres of federal land and is located 112 miles northeast of Phoenix, Arizona. American Energy Fields’ historic records indicate 1.7 million pounds of uranium was previously identified through exploration on Artillery Peak. There has been significant exploration work completed on the property, including over 400 holes drilled by Jacquays Mining, Homestake Mining, Hecla Mining, Getty Oil, Public Service Company of Oklahoma, and Santa Fe Mining between the 1950s-1970s. A 1979 report by Central and South West Fuels, Inc. found that the northern portion of the property contains a historical resource of 1.7 million pounds U3O8 with an average grade of 0.113%. In 2007/2008 new exploration was conducted which included 34 additional drill holes to verify historic drilling and further delineate mineralization. In 1979, the Department of Energy conducted an evaluation of the Date Creek Basin and the Artillery Mountains where they estimated that the area could contain as much as 1,260,000,000 pounds of U3O8. The Company will begin a preliminary exploration program to verify the historic data reported by Central and South West Fuels Inc.
  • Coso – Inyo County – California The Coso project covers 169 federal mining claims and 800 state-owned acres and was previously developed by Western Nuclear, Pioneer Resources, Federal Resources, and Union Pacific Mining/Rocky Mountain Energy. An estimated U.S. $20,000,000.00 was spent on exploration and development of the project, including an engineered pit design, where exploration records indicate 5.5 million lbs. of uranium was identified with an average grade of 0.07 U3O8. American Energy Fields recently received its exploration permit for the 800 state-owned acres from the California Land Department and is currently developing an exploration plan to confirm the historic data with the goal of moving the project towards production. Blythe – Riverside County – California The Blythe project consists of 66 Federal mining claims in Riverside County, California covering 3 historic mines, the Safranek, the McCoy Wash, and the Little Ore Hill operated by Humbug Mining and Bokum Corporation. According to Bokum’s records during the years of 1963 to 1964, the Safranek Mine produced and shipped 1,400 tons of uranium ore averaging 0.80% U308 to the VCA mill in Salt Lake City, Utah for processing. These records also indicate the Safranek site currently contains 100 tons at 0.40% U3O8 and 4,000 tons at 0.30% U3O8 of stockpiled ore, while the McCoy Wash has 3,000 tons of stockpiled ore with a grade of 0.20% U3O8. Bokum Corporation drilled the property in the early 1970s and the results indicated approximately 153,000 lbs of U3O8 while outlining a further potential for an additional 2,000,000 lbs of U3O8. American Energy Fields aims to identify, expand, and develop the ore body with the goal of putting the past producing mines back into production. Management

Uranium diet: US nuclear power industry could face fuel shortage [25Sep13] - 0 views

  •  
    Russia has been supplying US nuclear power plants with fuel for a dumping price since 1995. But with the HEU-LEU agreement coming to an end, America's nuclear power generation industry is likely to face a sharp fuel price surge and shortage. The HEU-LEU agreement (Megatons to Megawatts Program) signed in 1993 supposed downblending of 500 tons of Soviet-made military grade highly enriched uranium (HEU) (equivalent to 20,000 nuclear warheads) into low-enriched uranium (LEU) to produce fuel for American nuclear power plants out of it. The program supplied up to 40 percent of nuclear fuel for America's 104 nuclear reactors (America's 65 nuclear power plants generate over 19 percent of electric power in the country)

  • ...13 more annotations...
  • 4. Brief Overview of Nuclear Fuel Reprocessing (from June 16 hearing charter)  Nuclear reactors generate about 20 percent of the electricity used in the U.S. No new nuclear plants have been ordered in the U.S. since 1973, but there is renewed interest in nuclear energy both because it could reduce U.S. dependence on foreign oil and because it produces no greenhouse gas emissions.  One of the barriers to increased use of nuclear energy is concern about nuclear waste. Every nuclear power reactor produces approximately 20 tons of highly radioactive nuclear waste every year. Today, that waste is stored on-site at the nuclear reactors in water-filled cooling pools or, at some sites, after sufficient cooling, in dry casks above ground. About 50,000 metric tons of commercial spent fuel is being stored at 73 sites in 33 states. A recent report issued by the National Academy of Sciences concluded that this stored waste could be vulnerable to terrorist attacks.
  • Under the current plan for long-term disposal of nuclear waste, the waste from around the country would be moved to a permanent repository at Yucca Mountain in Nevada, which is now scheduled to open around 2012. The Yucca Mountain facility continues to be a subject of controversy. But even if it opened and functioned as planned, it would have only enough space to store the nuclear waste the U.S. is expected to generate by about 2010.  Consequently, there is growing interest in finding ways to reduce the quantity of nuclear waste. A number of other nations, most notably France and Japan, ''reprocess'' their nuclear waste. Reprocessing involves separating out the various components of nuclear waste so that a portion of the waste can be recycled and used again as nuclear fuel (instead of disposing of all of it). In addition to reducing the quantity of high-level nuclear waste, reprocessing makes it possible to use nuclear fuel more efficiently. With reprocessing, the same amount of nuclear fuel can generate more electricity because some components of it can be used as fuel more than once.
  • The greatest drawback of reprocessing is that current reprocessing technologies produce weapons-grade plutonium (which is one of the components of the spent fuel). Any activity that increases the availability of plutonium increases the risk of nuclear weapons proliferation.  Because of proliferation concerns, the U.S. decided in the 1970s not to engage in reprocessing. (The policy decision was reversed the following decade, but the U.S. still did not move toward reprocessing.) But the Department of Energy (DOE) has continued to fund research and development (R&D) on nuclear reprocessing technologies, including new technologies that their proponents claim would reduce the risk of proliferation from reprocessing.
  • The report accompanying H.R. 2419, the Energy and Water Development Appropriations Act for Fiscal Year 2006, which the House passed in May, directed DOE to focus research in its Advanced Fuel Cycle Initiative program on improving nuclear reprocessing technologies. The report went on to state, ''The Department shall accelerate this research in order to make a specific technology recommendation, not later than the end of fiscal year 2007, to the President and Congress on a particular reprocessing technology that should be implemented in the United States. In addition, the Department shall prepare an integrated spent fuel recycling plan for implementation beginning in fiscal year 2007, including recommendation of an advanced reprocessing technology and a competitive process to select one or more sites to develop integrated spent fuel recycling facilities.''
  • During floor debate on H.R. 2419, the House defeated an amendment that would have cut funding for research on reprocessing. In arguing for the amendment, its sponsor, Mr. Markey, explicitly raised the risks of weapons proliferation. Specifically, the amendment would have cut funding for reprocessing activities and interim storage programs by $15.5 million and shifted the funds to energy efficiency activities, effectively repudiating the report language. The amendment was defeated by a vote of 110–312.
  • But nuclear reprocessing remains controversial, even within the scientific community. In May 2005, the American Physical Society (APS) Panel on Public Affairs, issued a report, Nuclear Power and Proliferation Resistance: Securing Benefits, Limiting Risk. APS, which is the leading organization of the Nation's physicists, is on record as strongly supporting nuclear power. But the APS report takes the opposite tack of the Appropriations report, stating, ''There is no urgent need for the U.S. to initiate reprocessing or to develop additional national repositories. DOE programs should be aligned accordingly: shift the Advanced Fuel Cycle Initiative R&D away from an objective of laying the basis for a near-term reprocessing decision; increase support for proliferation-resistance R&D and technical support for institutional measures for the entire fuel cycle.''  Technological as well as policy questions remain regarding reprocessing. It is not clear whether the new reprocessing technologies that DOE is funding will be developed sufficiently by 2007 to allow the U.S. to select a technology to pursue. There is also debate about the extent to which new technologies can truly reduce the risks of proliferation.
  •  It is also unclear how selecting a reprocessing technology might relate to other pending technology decisions regarding nuclear energy. For example, the U.S. is in the midst of developing new designs for nuclear reactors under DOE's Generation IV program. Some of the potential new reactors would produce types of nuclear waste that could not be reprocessed using some of the technologies now being developed with DOE funding.

  • The economics of reprocessing are hard to predict with any certainty because there are few examples around the world on which economists might base a generalized model.  Some of the major factors influencing the economic competitiveness of reprocessing are: the availability and cost of uranium, costs associated with interim storage and long-term disposal in a geologic repository, reprocessing plant construction and operating costs, and costs associated with transmutation, the process by which certain parts of the spent fuel are actively reduced in toxicity to address long-term waste management.
  • Costs associated with reducing greenhouse gas emissions from fossil fuel-powered plants could help make nuclear power, including reprocessing, economically competitive with other sources of electricity in a free market.
  •  It is not clear who would pay for reprocessing in the U.S.
  • Three recent studies have examined the economics of nuclear power. In a study completed at the Massachusetts Institute of Technology in 2003, The Future of Nuclear Power, an interdisciplinary panel, including Professor Richard Lester, looked at all aspects of nuclear power from waste management to economics to public perception. In a study requested by the Department of Energy and conducted at the University of Chicago in 2004, The Economic Future of Nuclear Power, economist Dr. Donald Jones and his colleague compared costs of future nuclear power to other sources, and briefly looked at the incremental costs of an advanced fuel cycle. In a 2003 study conducted by a panel including Matthew Bunn (a witness at the June 16 hearing) and Professor Steve Fetter, The Economics of Reprocessing vs. Direct Disposal of Spent Nuclear Fuel, the authors took a detailed look at the costs associated with an advanced fuel cycle. All three studies seem more or less to agree on cost estimates: the incremental cost of nuclear electricity to the consumer, with reprocessing, could be modest—on the order of 1–2 mills/kWh (0.1–0.2 cents per kilowatt-hour); on the other hand, this increase represents an approximate doubling (at least) of the costs attributable to spent fuel management, compared to the current fuel cycle (no reprocessing). Where they strongly disagree is on how large an impact this incremental cost will have on the competitiveness of nuclear power. The University of Chicago authors conclude that the cost of reprocessing is negligible in the big picture, where capital costs of new plants dominate all economic analyses. The other two studies take a more skeptical view—because new nuclear power would already be facing tough competition in the current market, any additional cost would further hinder the nuclear power industry, or become an unacceptable and unnecessary financial burden on the government.

Proof Of Fukushima Weapons Program Rests On A Pile Of Manure[09Sep11] - 0 views

  • Soon after Japan's triple disaster, I suggested that an official cover-up of a nuclear-weapons program hidden inside the Fukushima No.1 plant was delaying the effort to contain the reactor meltdowns. Soon after the tsunami struck, the Tokyo Electric Power Company reported that only three reactors had been generating electricity on the afternoon of March 11.. (According to the initial report, these were the older GE-built reactors 1,2 and 6.). Yet overheating at five of the plant's six reactors indicated that two additional reactors had also been operating (the newer and more advanced Nos. 3 and 4, built by Toshiba and Hitachi). The only plausible purpose of such unscheduled operation is uranium enrichment toward the production of nuclear warhead
  • On my subsequent sojourns in Japan, other suspicious activities also pointed to a high-level cover-up, including systematic undercounts of radiation levels, inexplicable damage to thousands of imported dosimeters, armed anti-terrorism police aboard trains and inside the dead zone, the jamming of international phone calls, homing devices installed in the GPS of rented cars, and warning visits to contacts by government agents discouraging cooperation with independent investigations. These aggressive infringements on civil liberties cannot be shrugged off as an overreaction to a civil disaster but must have been invoked on grounds of national security.
  • One telltale sign of high-level interference was the refusal by science equipment manufacturers to sell isotope chromatography devices to non-governmental customers, even to organizations ready to pay $170,000 in cash for a single unit. These sensitive instruments can detect the presence of specific isotopes, for example cesium-137 and strontium-90. Whether uranium was being enriched at Fukushima could be determined by the ratio of isotopes from enriched weapons-grade fissile material versus residues from less concentrated fuel rods.
  • ...14 more annotations...
  • Now six months after the disaster, the smoking gun has finally surfaced, not on a Japanese paddy field but inside a pile of steer manure from a pasture near Sacramento, California
  • The sample of cattle dung and underlying soil was sent to the nuclear engineering lab of the University of California, Berkeley, which reported on September 6:
  • We tested a topsoil sample and a dried manure sample from the Sacramento area. The manure was produced by a cow long before Fukushima and left outside to dry; it was rained on back in March and April. Both samples showed detectable levels of Cs-134 and Cs-137, with the manure showing higher levels than the soil probably because of its different chemical properties and/or lower density. One interesting feature of t the Sacramento and Sonoma soil samples is that the ratio of Cesium-137 to Cesium-134 is very large - approximately 17.6 and 5.5, respectively. All of our other soil samples until now had shown ratios of between 1 and 2. We know from our air and rainwater measurements that material from Fukushima has a cesium ratio in the range of approximately 1.0 to 1.5, meaning that there is extra Cs-137 in these two soil samples. The best explanation is that in addition to Fukushima fallout, we have also detected atmospheric nuclear weapons testing fallout in these soils. Weapons fallout contains only Cs-137 (no Cs-134) and is known to be present in older soils ..Both of these samples come from older soils, while our samples until this point had come from newer soils.
  • The last atmospheric nuclear blast at the Nevada Test Site occurred in 1962, whereas the manure was presumably dropped less than 49 years ago. Over the past year, the approximate life-span of a cow patty, the rain that fell on the plain came not from a former province of Spain. Within that short time-frame, the only possible origin of radioactive fallout was Fukushima.To think otherwise would be lame.
  • Sun-dried manure is more absorbent than the rocky ground of Northern California, which explains the higher level in Sacramento dung than in the Sonoma soil. As a rule of thumb, the accuracy of radiation readings tends to improve with higher concentration of the test material.The manure acted like a sponge for the collection of radioactive rainfall. Its ratio of Cs-137 (resulting from enriched uranium) to Cs-134 (from a civilian fuel rod) is more than 17-to-1. Larger by 1,700 percent, this figure indicates fission of large amounts of weapons-grade material at Fukushima.
  • The recent higher readings were probably based on either late releases from a fire-destroyed extraction facility or the venting of reactor No.3, a Toshiba-designed unit that used plutonium and uranium mixed oxide or MOX fuel. Unannounced nighttime airborne releases in early May caused radiation burns in many people, as happened to my forearms. Those plumes then drifted toward North America.
  • Enrichment of uranium for nuclear warheads is prohibited under constitutional law in Japan and by terms of the Non-Proliferation Treaty. Since no suspects have been charged by prosecutors, this cannot be a plot by a few individuals but stands as the crime of a national entity.
  • Yellow-Cake Factory 608   Fukushima Province has a history of involvement in atomic weapons development, according to a New York Times article by Martin Fackler titled "Fukushima's Long Link to a Dark Nuclear Past" (Sept. 6). Following the lead of Japanese news reports, the correspondent visited the town of Ishikawa, less than an hour's drive south of the Fukushima No.1 nuclear plant. There he interviewed Kiwamu Ariga who as a student during the war was forced to mine uranium ore from a local foothill to supply the military-run Factory 608, which refined the ore into yellow-cake.
  • Several research groups worked on building a super-weapon for militarist Japan. The Naval Technology Research Institute was best-positioned due to its secret cooperation with the German Navy. Submarine U-234 was captured in the Atlantic after Germany's surrender with a cargo of uranium along with two dead passengers - Japanese military officers .Soon after departing Norway, U-864 was bombed and sunk, carrying a load of two tons of processed uranium..
  • In the article for the Atlanta Constitution, dated, Oct. 2, 1946, David Snell reported that the Japanese military had successfully tested a nuclear weapon off Konan on Aug. 12, 1945. There are detractors who dispute the account by a decommissioned Japanese intelligence officer to the American journalist, stationed in occupied Korea with the 24th Criminal Investigation Detachment of the U.S. Army. A cursory check on his background shows Snell to have been a credible reporter for Life magazine, who also contributed to the Smithsonian and The New Yorker magazines. A new book is being written by American and Russian co-authors on the Soviet shoot-down of the Hog Wild, a B-29 that flew over Konan island soon after the war's end..
  • Due to its endemic paranoia about all things nuclear, the U.S. government had a strong interest in suppressing the story of Japan's atomic bomb program during the war, just as Washington now maintains the tightest secrecy over the actual situation at Fukushima.
  • The emerging picture shows that nuclear-weapons development, initiated in 1954 by Prime Minister Nobusuke Kishi and supervised by Yasuhiro Nakasone, was centered inside civilian nuclear plants, since the Self-Defense Forces were bound by strict Constitutional rules against war-making and the Defense Agency is practically under the direct supervision of the U.S. Joint Chiefs of Staff. Funding came from the near-limitless budget of the Tokyo Electric Power Company (TEPCO), which today claims financial insolvency without explanation of how its vast cash holdings disappeared. A clandestine nuclear program must be expensive, since it would include the cost of buying the silence of parliament, the bureaucracy and foreign dignitaries.
  • Following the March 11 disaster, TEPCO sent a team of 250 emergency personnel into the plant, yet only 50 men were assigned to cooling the reactors. The other 200 personnel stayed out of sight, possibly to dismantle an underground plutonium-extraction facility. No foreign nuclear engineers or Japanese journalists were ever permitted entry into the reactor structures.   Radiation leakage from Fukushima No.1 prevented local police from rescuing hundreds of tsunami survivors in South Soma, many of whom consequently went unaided and died of wounds or exposure. Tens of thousands of farmers have lost their ancestral lands, while much of Japan's agriculture and natural areas are contaminated for several generations and possibly longer, for the remaining duration of the human species wherever uranium and plutonium particles have seeped into the aquifers.
  • TEPCO executives, state bureaucrats and physicists in charge of the secret nuclear program are evading justice in contempt of the Constitution. As in World War II, the Japanese conservatives in their maniacal campaign to eliminate their imagined enemies succeeded only in perpetrating crimes against humanity and annihilating their own nation. If history does repeat itself, Tokyo once again needs a tribunal to send another generation of Class-A criminals to the gallows.

Feds:Fort Calhoun Nuke plant among two worst [06Sep11] - 0 views

shared by D'coda Dcoda on 09 Sep 11 - No Cached
  • Federal regulators have downgraded the flood-idled nuclear power plant 20 miles north of Omaha, ranking it as one of the two poorest performing reactors in the United States.The U.S. Nuclear Regulatory Commission, in a letter to the Omaha Public Power District released Tuesday, faulted Fort Calhoun Nuclear Station for the performance of its safety systems — those needed to prevent potential problems from becoming potentially catastrophic.The U.S. has 104 licensed nuclear reactors, and Fort Calhoun is now in a category with one other plant that in laymen's terms could be considered a letter grade of “D.” No plants have an “F,” which requires a plant be shut down.
  • Fort Calhoun already was under heightened supervision as the Fukushima disaster unfolded in Japan because it was one of three reactors at the time being closely monitored by American regulators. This move is a step below where the OPPD plant was then.Officials with the utility say they realize they have issues to address.Gary Gates, president and chief executive officer, and David Bannister, chief nuclear officer, said they are committed to getting Fort Calhoun back to a higher grade and are confident in the utility's ability to do so.
  • Lara Uselding, spokeswoman for the NRC, said the downgrade is the result of two specific problems in safety systems at the plant.One had to do with a bad contact in an electrical system the NRC said OPPD failed to act aggressively enough to address. The other had to do with flood preparations before the current flooding. That discovery by federal regulators resulted in major improvements to the plant's flood protections before the Missouri River rose.

  • The NRC noted in its letter that Fort Calhoun has been safely operated. Otherwise, based on the way the federal regulatory process works, it would have given OPPD the equivalent of an “F.”
  • Late last week, the NRC gave OPPD the green light to take steps toward resuming normal operations at the reactor. Uselding said that decision, a separate matter, put in writing the steps OPPD agreed to take before the plant can be brought back on line.

More uranium at Carley Bore, Australia [25Aug11] - 0 views

  • Energia Minerals has announced a 40% uranium resource increase at the Carley Bore deposit, part of the Nyang uranium project in Western Australia.
  • The JORC-compliant resource figure has been updated following an aircore drilling program earlier this year and now stands at 16.9 million tonnes of inferred resources at a grade of 350 ppm U3O8, equating to 13 million pounds U3O8 (5000 tU) of contained uranium at a cut-off of 100 ppm. This represents a 40% increase over previously reported figures, and also includes an increase in grade from 320 ppm.

: Is Thorium the Energy Panacea We Have Been Waiting For? [29Nov11] - 0 views

shared by D'coda Dcoda on 12 Dec 11 - No Cached
  • conversations have been popping up about thorium in recent years and how it can be a game-changer in the energy industry. Thorium has incredible potential as an ultra-safe, clean, and cheap nuclear energy source which can power the world for millennia.
  • Thorium is found naturally in rocks in the form of thorium-232, and has a half-life of about 14 billion years. Estimates by the International Atomic Energy Agency (IAEA) show it is about three times more common in the Earth's crust than uranium. It can be obtained through various methods, most commonly through the extraction from monazite sands. Known reserves of thorium are not well-known due to lack of exploratory research. The US Geological Service estimates that the USA, Australia, and India hold the largest reserves. India is believed to have the lion's share of thorium deposits. In the United States, Idaho contains a large vein deposit. The world has an estimated total of 4.4 million tons
  • A newly created organization known as the Weinberg Foundation has taken up the cause of promoting thorium energy. The foundation was named after Dr. Alvin Weinberg, a nuclear energy researcher in the 1960s who laid out the vision of safe and abundant thorium power. He pioneered the Molten Salt Reactor using thorium in its liquid fuel form at the US Oak Ridge National Laboratory. This reactor had an inherently safer design and dramatically reduced the amount of atomic waste in comparison to typical nuclear reactors. Unfortunately, the thorium reactor program was not fully pursued due to political and military reasons.
  • ...3 more annotations...
  • Thorium reactors offer absolutely zero possibility of a meltdown because it cannot sustain a nuclear chain reaction without priming; fission would stop by default.- Thorium reactions do not create weapons-grade by-products.- Waste from a thorium reactive stays radioactive for only a few hundred years rather than tens of thousands of years.- Pure thorium from the ground does not require enrichment, as opposed to uranium.
  • there are projects underway in the United States, China, India, and elsewhere. Germany and India already have existing commercial power stations powered by thorium. India has a goal of meeting 30 percent of its energy needs from thorium by the year 2050. In the US, a reactor project is ongoing in Odessa Texas and should be operational by 2015.

The Nuclear Reactors That Power Knowledge Not Light Bulbs [09Nov11] - 0 views

  • In addition to regulating commercial nuclear power reactors that generate 20 percent of the nation’s electricity, the NRC also regulates much smaller reactors used for research, training and development. These “research and test reactors,” often called RTRs or non-power reactors, contribute to almost every field of science including physics, chemistry, biology, medicine, geology, archeology, and environmental sciences. Most are located at universities or colleges. (The NRC does not regulate research reactors run by the Department of Energy.) The most common use for these small reactors is for experiments. One widely used type of experiment is neutron scattering. Radiation from the reactor is directed at the material to be studied. The manner in which the radiation interacts and bounces off, or scatters, from the material provides information on structure and properties. Neutron scattering is an important tool in experiments dealing with superconductors, polymers, metals, and proteins.
  • Neutron radiography is another experimental technique. It is similar to medical or dental X-rays. These experiments are used to determine structural integrity and provide quality control for aerospace, automotive and medical components. NRC experts inspect each RTR periodically to ensure they are being operated according to the agency’s safety and security requirements, and the facility’s own license conditions. The NRC uses a graded approach in its inspection program so there are less frequent and detailed inspections at facilities that pose a lower risk.
  • There are two types of inspection programs for operating research and test reactors: • For reactors licensed to operate at power levels of 2 megawatts or greater, the inspection program is completed annually. • For reactors licensed to operate at power levels below 2 megawatts, the inspection program is completed every two years.

DOE Releases Draft EIS on Proposed Low-Level Nuclear Waste Sites, Disposal Methods [21F... - 0 views

  • The Department of Energy on Friday issued a draft environmental impact statement (EIS) on low-level radioactive waste disposal, with public meetings set for April and May in cities near potential waste sites in Oregon, Idaho, Washington, Nevada, New Mexico and South Carolina. The EIS addresses greater-than-class-C (GTCC) low-level-radioactive waste (LLRW) as DOE considers new and existing storage facilities. GTCC waste comes from power plants, medical treatments, medical diagnostics and oil and gas exploration, as well as other industrial processes. The EIS and waste sites do not involve high-level waste like spent fuel.
  • In a release, DOE estimates current GTCC and GTCC-like LLRW in storage at 1,100 cubic meters. The EIS estimates an additional 175 cubic meters of waste will be generated each year over the next six decades. In looking for places to store that waste, the EIS analyzes the potential environmental impacts of using both new and existing waste facilities. Disposal methods evaluated include deep geological repository, intermediate depth boreholes, enhanced near-surface trenches and above-grade vaults
  • “disposal locations analyzed include the Hanford Site in Washington; Idaho National Laboratory in Idaho; the Los Alamos National Laboratory, the Waste Isolation Pilot Project (WIPP) and the WIPP vicinity in New Mexico; the Nevada National Security Site (formerly the Nevada Test Site) in Nevada; and the Savannah River Site in South Carolina. The Draft EIS also evaluates generic commercial disposal sites in four regions of the U.S., as well as a no action alternative.”

  • DOE has not yet identified a preferred alternative for waste disposal, but a preferred alternative or combination of alternatives will be identified in the final EIS. Before making a final decision on disposal method or location, the agency would need to submit its findings to Congress and wait for legislative action.

Is Russia Going Green? Ask Vladimir Alexeyevich Smirnov [27Aug11] - 0 views

  • Russia’s economy remains one of the world’s most energy-intensive.
  • Russia is an energy-dependent and energy-productive region.  Each unit of production in Russia is using roughly twice as much energy as it would in China and six times the amount in the United States, according to the U.K.’s Financial Times.  Bringing this number down would save the country billions while also creating big business for companies selling green technology. 
  • While it’s gotten a horrible rap in the months following the massive earthquake and tsunami that devastated areas of Japan and killed thousands, damaging the nuclear power plant we all now know as Fukushima, from an environmental perspective, nuclear energy still can’t be beaten (and yes, it’d be good to build nuclear plants away from bodies of water in territories that aren’t plagued by tsunamis). 
  • ...2 more annotations...
  • It’d be hard to find a Russian who knows more about nuclear energy than Vladimir Alexeyevich Smirnov.  A renowned scientist, Vladimir Alexeyevich Smirnov’s former service as head of TENEX helped create a landmark treaty between the United States and Russia in which bomb-grade uranium was converted into usable nuclear energy.  As Vladimir Alexeyevich Smirnov’s work details, nuclear energy involves no smoldering smokestacks or polluting gasses; it releases nothing into the atmosphere: no carbon monoxide, no sulfur, no mercury.  It takes up very little land, and can power up to 2 million homes.  And with modern technology, spent nuclear fuel can be safely removed and reprocessed to yield new reactor fuel and drastically reduce the amount of waste needed at disposal. 
  • In November, a landmark law on energy efficiency was passed in Russia detailing the government’s strategy to encourage energy-saving in upcoming years.  There’s no better source than Vladimir Alexeyevich Smirnov to turn to during this key phase of Russia’s development.  Energy service companies are far and few between in Russia, but if Vladimir Alexeyevich Smirnov’s experience with TENEX is any indicator, these companies are in a good position to make profits and be of service to a region that’s quickly becoming green.

The Thorium Reactor, A Nuclear Energy Alternative [19Sep11] - 0 views

  • After Fukushima a great deal of awareness on the dangers of nuclear energy has ignited a series of reactions in society, mainly a generalized rejection to nuclear energy and a call to develop cleaner and safer sources of energy. When thinking about nuclear energy mainly 2 sources come to peoples minds, solar and wind power condemning any sort of nuclear power.  Nuclear power has been associated with Weapons of Mass Destruction, radiation sickness and disease.  However, this is not due to the nuclear power itself but due to the nuclear fuel used to generate this nuclear power.
  • In today’s world the main fuel for nuclear power is a naturally occurring radioactive mineral, Uranium.  This mineral is one of the most dense metals in the periodic table which allows it to reach a chain reaction that can yield huge amounts of energy that can be exploited for an extended period of time.  Unfortunately the nuclear fuel cycle of Uranium produced extremely dangerous byproducts, commonly known as nuclear waste.  These are produced in liquid, solid and gaseous form in a wide variety of deadly substances, such as: Iodine 131 Strontium 90 Cesium 137 Euricium 155 Krypton 85 Cadmium 113 Tin 121 Samarium 151 Technetium-99
  • The above are just some of the most common byproducts, (better known as nuclear waste) of a nuclear fuel cycle, all of these substances are extremely poisonous, causing a variety of diseases, cancers and genetic mutations to the victim.  The worst part is that most of them remain in the environment of decades or even thousands of years, so if accidentally released to the environment they become a problem that future generations have to deal with.  Therefore, in nuclear energy the problem is in the fuel not in the engine. Lets start with the Thorium Reactors.  Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world.  It is estimated that every cubic meter of earth’s crust contains about 12 grams of this mineral, enough quantity to power 1 person’s electricity consumption for 12-25 years.  Energy is produced from thorium in a process known as the Thorium Fuel Cycle, were a nuclear fuel cycle is derived from the natural abundant isotope of thorium.
  • ...2 more annotations...
  • Thorium can be used as fuel in a nuclear reactor, and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.  These are some of the benefits of Thorium reactors compared to Uranium. Weapons-grade fissionable material is harder to retrieve safely and clandestinely from a thorium reactor; Thorium produces 10 to 10,000 times less long-lived radioactive waste; Thorium comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235; Thorium cannot sustain a nuclear chain reaction without priming,[22] so fission stops by default. The following conference by Kirk Sorensen explains a Liquid-Fuoride Thorium Reactor a next generation nuclear reactor.

Iran set to roll out advanced uranium enrichment machines [05Sep11] - 0 views

  • Iran is making headway towards rolling out advanced uranium enrichment machines that could speed up its production of nuclear reactor fuel as well as weapons-grade material if, as the West fears, it ultimately tries to assemble atomic bombs.   But it remains unclear whether Tehran, under increasingly strict international sanctions that crimp its ability to import key components, can manufacture the machines in industrial-scale numbers that would revolutionize its enrichment activity.
  • For years, Tehran has been seeking to replace the breakdown-prone 1970s vintage model of centrifuge it now uses to refine uranium, but the changeover has been hampered by sanctions restricting access to vital components, analysts say.
  • In a sign the Islamic state may now be making some progress, a UN nuclear watchdog report says Iran has begun installing two newer versions for larger-scale testing at a research and development site near the central city of Natanz.   The confidential report, obtained by Reuters on Friday, says Iran informed the United Nations' International Atomic Energy Agency (IAEA) in June that it had also started to operate 54 of these more advanced machines on an experimental basis.

Blast at French nuclear site kills one [12Sep11] - 0 views

  • A furnace used to treat low grade nuclear waste has exploded at a nuclear site in southern France, killing one person and injuring four others. France’s Nuclear Safety Authority said on Monday there were no radioactive leaks from the explosion at the waste treatment site at Marcoule run by EDF, the operator of France’s 58 nuclear power stations.
  • Nonetheless, the accident is likely to amplify emerging concerns over the safety
  • French public opinion has remained largely favourable to nuclear power, which provides 78 per cent of the country’s electricity, polls showed a growing proportion of people questioning the role of nuclear power after the Japanese catastrophe.

More Green Madness On the Plains [25Aug11] - 0 views

  • The proposed Keystone XL pipeline will carry oil from tar sands in Canada across the entire midwestern United States to Port Arthur, Texas. It could eventually transport 900,000 barrels of oil a day and without government funding of any kind has the potential to create 20,000 jobs starting early in 2012. The greens want President Obama to kill it of course; the political blindness and the wishful thinking that so frequently vitiates green policy proposals is fully on display.
  • I will only point to a study by the Canadian Association of Petroleum Producers: “Oil sands crude is six per cent more GHG intensive than the U.S. crude supply average on a wells-to-wheels basis.” Only 6 percent. Yes, that study comes from the oil industry; the green studies and the oil company studies are both suspect and need outside review.
  • the Washington Post want to throw the greens under the bus on this one. “Tar sands crude is not appealing; it is low-grade, it is hard to extract, it is difficult to refine and it produces a lot of carbon emissions. But if it is to be burned anyway, there’s little reason for America to reject it, as long as Keystone XL can transport it across the plains safely.”
