Exelon has begun a series of nuclear power plant uprates that will add between 1,300 MW and 1,500 MW of generating capacity at its existing fleet of nuclear units over the next eight years, the company said Friday. The first of the uprates, totaling about 38 MW, was confirmed last week following upgrades at Exelon's Quad Cities plant near Cordova, Illinois. Uprate projects, some of which require US Nuclear Regulatory Commission approval, improve efficiency and increase electricity output of nuclear units through upgrades to plant equipment, Chicago-based Exelon said. The projects take advantage of new production and measurement technologies, new materials and experience from decades of nuclear power operations, the company said. Uprate efforts are underway at Exelon's Limerick and Peach Bottom nuclear plants in Pennsylvania, and the Dresden, LaSalle and Quad Cities plants in Illinois. Those are expected to produce nearly 25% of the added capacity. The remainder of capacity would come from uprates at nine other plants beginning in 2010 and ending in 2017.

US President Barack Obama's choice to head the Department of Energy's nuclear power programs told a Senate panel Tuesday that he would more closely integrate the development of new nuclear power and solving the problem of nuclear waste. "It is critical to take an integrated approach that considers the entire nuclear fuel cycle," Warren Miller told the Senate Energy and Natural Resources Committee during his confirmation hearing. Miller has been nominated as both assistant secretary of nuclear energy and the director of the Office of Civilian Radioactive Waste Management. During the previous administration, DOE staffed the positions with separate officials. Combining the two offices under one official comes as the administration moves to kill the controversial Yucca Mountain nuclear waste repository, which has long been planned for Nevada.

Constellation Energy: Nuclear Operators Although it is too dangerous, too expensive and too centralized to make sense as an energy source, nuclear power won't go away, thanks to equipment makers and utilities that find ways to make the public pay and pay. Case in point: Constellation Energy Group, the operator of the Calvert Cliffs nuclear plant in Maryland. When Maryland deregulated its electricity market in 1999, Constellation - like other energy generators in other states - was able to cut a deal to recover its "stranded costs" and nuclear decommissioning fees. The idea was that competition would bring multiple suppliers into the market, and these new competitors would have an unfair advantage over old-time monopoly suppliers. Those former monopolists, the argument went, had built expensive nuclear reactors with the approval of state regulators, and it would be unfair if they could not charge consumers to recover their costs. It would also be unfair, according to this line of reasoning, if the former monopolists were unable to recover the costs of decommissioning nuclear facilities. In Maryland, the "stranded cost" deal gave Constellation (through its affiliate Baltimore Gas & Electric, BGE) the right to charge ratepayers $975 million in 1993 dollars (almost $1.5 billion in present dollars). Deregulation meant that Constellation's energy generating assets - including its nuclear facility at Calvert Cliffs - were free from price regulation. As a result, instead of costing Constellation, Calvert Cliffs' market value increased.

The cost to build a new nuclear power plant in Texas has risen to $10 billion, up from early estimates, but much below price tags of other proposed U.S. nuclear projects, an executive with NRG Energy Inc's nuclear development arm said on Tuesday. The "all in" cost to build two 1,350-megawatt nuclear reactors in South Texas has risen 40 percent from 2006 estimates which did not include financing costs, Steve Winn, chief executive of Nuclear Innovation North America (NINA), told the Reuters Global Energy Summit. While higher, NINA's current estimate is more than $10 billion under estimates from other nuclear developers that operate in states where regulators determine how much money utilities can charge customers for new power plants.

Reuters reports that an executive of French oil company Total expects oil production to peak before the end of the next decade - and wants the company to move into nuclear power in the post-oil age (something Bucky Fuller predicted would be the next step for the oil industry) - Total sees nuclear energy for growth after peak oil. French oil and gas giant Total (TOTF.PA: Quote, Profile, Research, Stock Buzz) is targeting nuclear energy to drive growth long after oil and gas output peak, a top executive said on Monday. "In the future, energy demand will be constrained by tight supply," Arnaud Chaperon, Total's senior vice president for electricity and new energies, said in a presentation to a nuclear energy conference in Qatar. "Oil and gas will still play a big role in the energy balance. But in the electrification of the world economy, nuclear will play a major role, together with the development of solar and other renewables ... That is why Total is very interested in developing nuclear and renewables."

The UK will be forced to rely on imported natural gas to meet its emerging shortfall in power generation, with a lack of capacity in the nuclear construction industry meaning there is not enough time to roll out a new generation of nuclear stations, EDF said Friday. The UK is set to lose around 22.5 GW of power generation by 2020 due to closures of ageing nuclear stations and coal-fired plant that do not conform to European emissions regulations.

A Nuclear Regulatory Commission (NRC) member's recent call for the agency to require nuclear power plants to better protect high-level radioactive waste on site was seconded by the Union of Concerned Scientists (UCS), which has advocated for safer storage of spent nuclear fuel rods for years. In a May 13 speech at a nuclear industry trade group forum, NRC Commissioner Gregory B. Jaczko said it is much safer to store spent nuclear fuel rods in steel and concrete containers, called dry casks, than in large water-filled concrete pits, known as wet pools. He recommended that his agency require plants to expeditiously transfer spent fuel from wet pools to dry casks rather than allow it to accumulate in the pools.

"Aided by federal and state tax breaks, solar energy will be cheaper than building new nuclear power plants, according to a North Carolina study released today. Dr. John Blackburn, the emeritus chair of economics and former chancellor of Duke University, said the costs of new nuclear plants continues to rise while electricity generated from solar voltaic panels is only half the cost of 12 years ago. In a study commissioned by the environmental group NC Warn, Dr. Blackburn estimates that the cost of new nuclear plants is now about 16 cents per kilowatt-hour and headed higher while solar energy can be generated with rooftop panels and solar farms in North Carolina for a comparable rate and solar costs are trending down. Solar costs are cut by about one-third because of state and federal tax credits, but Dr. Blackburn said the nuclear industry also benefits by federally backed insurance, loan guarantees and research assistance. "The message is that solar is here and now and not something exotic for the future," Dr. Blackburn said."

Twenty-five years ago, the Nuclear Freeze campaign mobilized hundreds of thousands of Americans to demand an end to the testing, production, and deployment of new nuclear weapons. At that time, advocating the complete abolition of nuclear weapons was a fringe position confined to a few utopians on the left. Even most antinuclear activists struggled getting past the "you can't put the genie back in the bottle" common sense of pundits and arms control experts.

"Zelenogorsk, a remote centre of nuclear technology, is a closed city with big ambitions. A French multinational has arrived with new technology and an eye toward renewable energy A Soviet-era nuclear plant in a closed city in Siberia is making a bid to become a player in the future of sustainable energy. Related Articles * Phenomenon of closed cities * Picture gallery: Russia's closed cities Since 1995, Zelenogorsk, a former closed city, has processed fuel for the nuclear reactors that supply many Americans with their electricity. Now it hopes that embracing a French company with new technology could lead to a more significant role. "

In remarks focused on the promise of renewable energy and demand-side management, US Federal Energy Regulatory Commission Chairman Jon Wellinghoff on Wednesday suggested that there may never be another new nuclear or coal power plant built in the country. Pointing to upwards of 1,000 GW of potential wind energy in the Midwest and West, new solar power production and storage technologies and emerging hydrokinetic power resources, Wellinghoff asserted that renewables are poised to play a substantial, gap-filling role in the US energy picture.

Ontario, Canada's economic hub, announced Monday the suspension of its plan to build two new nuclear reactors, citing concerns about vendor Atomic Energy Canada Limited's viability, and pricing. The provincial government said AECL's bid to build the two new nuclear power plants at its Darlington station, 43 miles (70 kilometers) east of Toronto, by 2018 was the only one to meet its terms and objectives. The project was to be the first step in the modernization of Ontario's aging nuclear fleet. France's Areva and Westinghouse Electric Company, a subsidiary of Japan's Toshiba, had also bid on the project in February.

About 350 people attended a meeting on a proposed $2 billion uranium enrichment plant planned by French-owned Areva SA to make fuel for commercial nuclear power reactors. The meeting was held by the federal Nuclear Regulatory Commission to outline its licensing process for the plant, slated to be operating by 2014. In a community that's been home to the Idaho National Laboratory since 1949, many at Wednesday's event said they were eager for the Nuclear Regulatory Commission to allow construction of the proposed plant to be located about 20 miles from Idaho Falls.

With research, development and implementation of alternative and renewable energy sources pushed to the front-burner, attention has naturally turned to nuclear power. But if nuclear power is to become more of a player in our energy future, the problem of where to dispose of nuclear waste must be addressed and solutions found.

Discussion of nuclear power regularly leads to the issue of what to do with the waste created during power generation. One course of action many experts and scientists support is building geologic repositories where the dangerous, long-lived waste can be stored--for instance, inside of a mountain. Throughout the next year, the Bulletin's web-edition will present a country-by-country analysis of how certain nations are proceeding with the disposal of the waste produced by their nuclear power plants and reactors.

Antoinette Bonsignore, writing on behalf of the Alliance of Nuclear Worker Advocacy Group, has responded the Labor Dept.'s recent response (by Rachel Leiton) to the group's criticisms of the federal agency and the performance evaluation of the sick nuclear workers compensation program. The letter states that ANWAG stands behind its earlier criticisms and said important issues continue to be ignored by the Labor Department. Here is a copy of the letter, dated today: ALLIANCE OF NUCLEAR WORKER ADVOCACY GROUPS

The US Chamber of Commerce on Thursday launched a campaign to promote "green projects" it said could proceed if only environmental groups, local governments and others would stop opposing sponsors' efforts to obtain sites and permits for the ventures. At a news conference at the chamber's Washington headquarters, officials said permitting and siting disputes, activist opposition and other "green tape" has killed or delayed "thousands" of coal, ethanol, natural gas, nuclear, transmission and wind projects.

If I am travelling down an "irrational" road to renewables, as Richard Phillips implies (Letters, 11 September), then I am not alone. Last year, solar PV generation capacity grew by 70% around the world, wind power by 29% and solar hot water increased by 15%. By 2008, renewables represented more than 50% of total added generation capacity in both the US and Europe, ie more new renewables capacity was installed than new capacity for gas, coal, oil, and nuclear combined; with no emissions, no wastes and no security issues to worry about - and no worries about fuel running out, or increasing in price. It's true the energy available from some renewable sources, like wind, varies over time, but we already have to have backup capacity for other plants (including for nuclear plants), which is also used to deal with the daily energy demand peaks. With variable renewables on the grid, these backup plants have to be used a bit more often, adding a small extra cost and, if they are fossil-fuelled, reducing the amount of emissions saved very slightly. But hydro can also be used as backup, and increasingly, so can other types of non-variable renewable source, including biomass and geothermal energy.

Get set for a new government carbon tax designed to subsidise the nuclear industry. The Guardian's Tim Webb says that figures he obtained show the additional levy would add £44 to an annual electricity bill of £500 - that's a nearly 10% increase

The UK's renewable energy targets could prove both costly and risky, and nuclear energy is the most reliable viable low-carbon alternative, according to the House of Lords Economic Affairs Committee. The committee's report - entitled The Economics of Renewable Energy - acknowledges government commitments to increase renewable energy use, but is sceptical as to whether the target of 15% renewables for the UK by 2020, proposed by the European Union (EU), can be met. It also warns that an over-reliance on intermittment power generation options, such as wind energy, could prove both costly and risky in terms of security of supply.
