Bangladesh and Russia signed a framework agreement for Russian cooperation for Bangladesh's first nuclear plant. Bangladesh aims to produce at least 2,000 megawatts of electricity by 2020 from two units of the proposed Rooppur plant and also to have nuclear energy account for 10 percent of its total power generation by that time, Bangladeshi state news agency BSS reports. The agreement, signed Friday in Russia, calls for the transfer of materials, technologies, equipment and services to implement joint programs in the field of the use of nuclear energy for peaceful purposes.

The explosion at the Fukushima nuclear power plant is being described as caused by a "hydrogen build-up" The situation harks back to the "hydrogen bubble" that was feared would explode when the Three Mile Island plant in 1979 underwent a partial meltdown. The hydrogen explosion problem at nuclear power plants involves a story as crazy as can be. As nuts as using nuclear fission to boil water to generate electricity is, the hydrogen problem and its cause cap the lunacy. Eruption of hydrogen gas as a first reaction in a loss-of-coolant accident has been discussed with great worry in U.S. government and nuclear industry literature for decades.

Two out of the six damaged reactors at the Fukushima Daiichi Nuclear Power Station are now under control in a state known as "cold shutdown" after engineers restored emergency water pumps using diesel generators. The reactors, Nos. 5 and 6, had already been shut down before last week's historic earthquake and tsunami, posing less of a risk than the other reactors at the plant. But their cooling systems were knocked out, and the fuel rods left inside the reactor started to heat up, together with spent fuel rods stored in a separate storage pool. "We are getting closer to bringing the situation under control," Tetsuro Fukuyama, the deputy chief cabinet secretary, said of the entire plant late Sunday. The Tokyo Electric Power Company, which runs the plant, had appeared to suffer a serious setback as officials said that pressure buildup at the ravaged No. 3 reactor would require the venting of radioactive gases. The reactor contains a highly toxic fuel that includes reclaimed plutonium. This announcement came after an all-out mission Saturday to cool the reactor by firefighters, who doused the it with 2,400 tons of water over 14 hours.

"As Japan approaches the six-month anniversary of its worst nuclear disaster, when an unprecedented meltdown occurred in three of the Fukushima No. 1 Nuclear Power Plant's reactors in a combination of natural and manmade calamities, the road to recovery is still long and unclear. In anticipation of the anniversary, the Mainichi looks back over the past six months to outline what has been done, learned, and where Japan currently stands on the issue in this time of crisis. On March 11, a magnitude 9.0 earthquake followed by a series of tsunami waves -- the worst in the history of Japan -- severely damaged the Tokyo Electric Power Co. (TEPCO)-operated Fukushima No. 1 nuclear complex, located along the coast of the towns of Futaba and Okuma in Fukushima Prefecture. As a result of the disaster, all external power sources were lost, causing the supply of cooling water to the plant's No. 1, 2 and 3 reactors to stop. Hydrogen was generated as a result of a chemical reaction between fuel rods and water, leading to hydrogen explosions which badly damaged reactor buildings. The government, which initially estimated the accident level at 4 on the International Nuclear Event Scale (INES), later raised the level to 7 -- the highest rank. This matched the level of the Chernobyl catastrophe, which at that stage was the worst nuclear accident in history."

Some of the spent nuclear fuel rods stored in the No. 4 reactor building of the crisis-hit Fukushima Daiichi power plant were confirmed to be damaged, but most of them are believed to be in sound condition, plant operator Tokyo Electric Power Co. said Wednesday. The firm known as TEPCO said its analysis of a 400-milliliter water sample taken Tuesday from the No. 4 unit's spent nuclear fuel pool revealed the damage to some fuel rods in such a pool for the first time, as it detected higher-than-usual levels of radioactive iodine-131, cesium-134 and cesium-137. The No. 4 reactor, halted for a regular inspection before last month's earthquake and tsunami disaster, had all of its 1,331 spent fuel rods and 204 unused fuel rods stored in the pool for the maintenance work and the fuel was feared to have sustained damage from overheating. The cooling period for 548 of the 1,331 rods was shorter than that for others and the volume of decay heat emitted from the fuel in the No. 4 unit pool is larger compared with pools at other reactor buildings. According to TEPCO, radioactive iodine-131 amounting to 220 becquerels per cubic centimeter, cesium-134 of 88 becquerels and cesium-137 of 93 becquerels were detected in the pool water. Those substances are generated by nuclear fission. The government's Nuclear and Industrial Safety Agency said the confirmed radioactive materials were up to 100,000 times higher than normal but that the higher readings may have also been caused by the pouring of rainwater containing much radioactivity or particles of radiation-emitting rubble in the pool.

"You won't hear this a lot, but several reactors at the Fukushima I nuclear power plant have been in full meltdown for a while now. The authorities don't know how to cool the reactors or remove the massively radioactive fuel cores. This is very likely now the world's worst ever nuclear disaster. By SIPHO HLONGWANE. The Tokyo Electrical Power Company (Tepco), the owners and operators of the Fukushima nuclear plant recently admitted the accident had released more radioactive material into the environment than Chernobyl in 1986, which would make it the worst nuclear accident ever recorded. The crisis at the plant followed a 9.0 magnitude earthquake that hit off the coast of Japan on 11 March 2011, followed by a tsunami and series of aftershocks. The natural disaster left 23,000 people dead or missing, but also severely crippled the Fukushima nuclear power plant. The plant was hit by a barrage of tsunamis immediately after the earthquake, one measuring 14m, which caused a power loss in the plant and massive damage to low-lying generators and pumps. The plant's cooling facilities were crippled, leading to the overheating of the reactors."

"A government official who released a book on May 20 criticizing the government's response to the Fukushima nuclear disaster has been asked to leave his post. Sources say that Shigeaki Koga, 55, attached to the secretariat of the Ministry of Economy, Trade and Industry (METI), was asked by Kazuo Matsunaga, a high-ranking METI official, whether he could resign on July 15. Koga is said to have held off on responding, saying the request was "too sudden." Koga has also pushed for changes to the country's energy policy, such as a separation of electric power generation and transmission fiercely opposed by power companies, and criticized the Democratic Party of Japan's (DPJ) reforms to the civil service."

"The emergency evacuation preparation zone between 20 and 30 kilometers from the Fukushima No. 1 nuclear power plant may be scrapped by the end of next month, it was learned Thursday. The government will soon set preconditions for eliminating the zone and start discussions with local governments, as the Step 1 phase to stably cool the plant's reactors has been generally achieved by the mid-July target in Tokyo Electric Power Co.'s timetable for bringing the troubled plant under control. People in the two sections of the emergency evacuation preparation zone have been asked by the government to make preparations to evacuate or stay indoors in the event of an emergency. Many residents in the zone already have left."

The Minister of Communication, Dr. Benjamin Aggrey-Ntim, has announced cabinet's decision, that Ghana should have nuclear energy Power Plant by 2018. The Plant will produce 400 mega watts of electricity to production from hydro and thermal sources. The Regional Training Course for Trainers is in the use of ICT materials in Nuclear Analytical Techniques.

"According to a study by the International Panel on Fissile Materials, fast breeder reactors may not the answer to the problem of long term storage for nuclear waste. The IPFM report concludes that the problems with fast breeder reactors make it hard to dispute that such reactors are expensive to build, complex to operate, susceptible to prolonged shutdown as a result of even minor malfunctions and difficult and time-consuming to repair. Plagued by high costs, often multi-year downtime for repairs (including a 15-year reactor restart delay in Japan), multiple safety problems (among them often catastrophic sodium fires triggered simply by contact with oxygen) and unresolved proliferation risks, fast breeder reactors already have been the focus of more than $50 billion in development spending, including more than $10 billion each by the U.S., Japan and Russia."

"President Obama may be pressing for the nation to increase its supply of nuclear power, but the market is pushing in the opposite direction-at least in the view of one of the leading figures in the U.S. nuclear business. John Rowe, chief executive of Chicago-based Exelon, operator of the nation's largest fleet of nuclear power stations, says the economics of the electricity business have changed sharply in just the past two years, dimming the prospects for a significant number of new nuclear reactors in the United States."

Plans for Britain's future nuclear supply emerged in sharp focus yesterday after the French power giant EDF unveiled a £12.5bn deal to buy British Energy and build four new reactors in the UK. The state-owned company, already one of the UK's top six energy suppliers, plans to take over British Energy's eight nuclear generators, including Hunterston B and Torness in Scotland, and has identified six potential sites for its new model of water-pressurised reactor south of the border.

The Maryland Public Service Commission's (PSC) issuance today of a Certificate of Public Convenience and Necessity to UniStar Nuclear is a costly step in the wrong direction for Maryland's energy future. This permit serves as the state's nod to construct a new uranium-fueled reactor in southern Maryland, a decision that not only could prove to be extraordinarily costly for taxpayers - as testimony provided to the PSC made clear - but tethers Maryland to continued reliance on dirty energy generation rather than moving our state toward becoming a leader in clean energy. The permit in its current form subjects UniStar Nuclear - a joint venture between Constellation Energy and the French-state controlled Electricite de France (EDF), which increasingly controls Constellation itself - only to some minor conditions.
