Nuclear

Achieving a balance between affordable and sustainable electricity while improving reliability is a challenge unlike any the electricity sector has faced since its inception. Technology innovations in key areas such as energy efficiency, smart grid, renewable energy resources, hardened transmission systems, and long-term operation of the existing nuclear and fossil fleets are essential to shaping the future of electricity supplies.

North American shale gas was supposed to realign the generation fleet here and abroad (thanks to anticipated exports) far into the future. Turns out, that’s not exactly how the near term is shaping up. Despite stagnant (and even putrid) economies and legislative bodies in the U.S. and EU, there promises to be sufficient market volatility to keep everyone alert.

Exports of natural resources have given Russia increased global political and economic clout. But domestically, the world’s fourth-largest generator of electricity has had to embark on the most ambitious reforms ever undertaken to modernize dilapidated Soviet-era power infrastructure and incentivize a massive capacity expansion to support a revived economy.

The Nebraska Public Power District’s (NPPD’s) Board of Directors on Friday unanimously voted to increase the amount of power produced at its 800-MW Cooper Nuclear Station by 146 MW through an extended power uprate.

Fuel for power generation will account for about 55% of demand-related energy growth through 2040, ExxonMobil forecasts in its freshly released annual energy forecast. Like several other forecasters, the Irving, Texas–based oil and gas company also predicts that natural gas will emerge as the leading source of electricity generation by 2040. Among key findings in […]

While announcing that staff would meet with Southern California Edison (SCE) representatives on Dec. 18 to discuss the utility’s proposal to restart the San Onofre Nuclear Generating Station’s (SONGS’) Unit 2, the Nuclear Regulatory Commission (NRC) warned that the meeting was "only one step in a long process," and that "a final decision on whether […]

The Nuclear Regulatory Commission (NRC) on Friday announced it was proposing to amend rules that govern low-level radioactive (LLR) waste disposal facilities. The proposal, published in the Federal Register, requires new and revised site-specific analyses and would permit the development of criteria for waste acceptance based on the results of those analyses.

After a four-year analysis, UK nuclear regulators on Thursday approved the generic nuclear design of the UK EPR proposed by France’s EDF and AREVA, confirming that it meets regulatory expectations on safety, security, and environmental impact. The decision paves the way for EDF to begin construction on two EPRs at Hinkley Point in Somerset.

A day after French utility EDF released a cost update for its Flamanville EPR reactor under construction in Normandy, France, claiming increases of a stunning $2.6 billion—bringing overall estimated costs for the advanced reactor to $10.5 billion—Italian power giant Enel formally withdrew its participation from that project and five other French EPR projects.

Compared to projections from last year, an Early Release Overview of the Energy Information Administration’s (EIA’s) Annual Energy Outlook 2013 (AEO2013) released on Wednesday foresees higher gas production and, with it, a higher share of gas generation by 2040. The outlook also projects a growing share of renewable and nuclear power, but dampened future coal use.

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the eighth, ninth, and 10th chapters, “Flightless Birds and Flying Elephants,” “The Devil Flies Nukes,” and “Flatulence in Space,” the concluding chapters of the “Up in the Air: Flights of Radioactive Fancy” section.

The U.S. Department of Energy contracted Shaw AREVA MOX Services LLC to design, construct, and operate a Mixed Oxide (MOX) Fuel Fabrication Facility (MFFF) at its Savannah River Site in South Carolina. The MFFF will convert depleted uranium and excess weapons-grade plutonium stockpiles, equivalent to approximately 17,000 nuclear weapons, into MOX fuel assemblies that will be used in U.S. nuclear power plants by 2018.

Note on the Oconee Top Plant Some of our readers may have been confused by the wording of a press release about our November issue’s nuclear Top Plants, the table of contents blurb about Duke’s Oconee plant, or a sentence in the cover story about that plant. In the interest of brevity, it seems we […]

The U.S. Department of Energy (DOE) has announced an award to support a new project to design, license, and help commercialize small modular reactors (SMR) in the U.S. The project supported by the award will be led by Babcock & Wilcox (B&W) in partnership with the Tennessee Valley Authority and Bechtel.

No other country has been as frequently cited as an example of exploiting the virtues of a nuclear-heavy energy policy as France. Deriving more than 75% of its electricity from 58 operational nuclear reactors with a total capacity of about 63 GW, France has one of the lowest costs of generation and is the world’s largest net exporter of power, earning €3 billion ($3.9 billion) a year from sales of surplus power to buyers beyond its borders. But that is all about to change.

When a nuclear power plant experiences ground motion due to an earthquake, an evaluation may be needed before allowing the plant to continue operating or to resume operating if it has been shut down, as was the case after the seismic event that shut down both units at Dominion’s North Anna Power Station on August 23, 2011.

In 2007, Dominion Resources contracted Alstom to perform steam turbine retrofits on two generating units at its North Anna nuclear power station. The Unit 1 retrofit, with its ongoing instrumentation upgrade, was the second to be completed at the North Anna plant and the fourth overall for Dominion. Completion of this project marked a significant milestone in terms of both technical achievement and investment in providing clean, safe, and reliable baseload electricity for Dominion customers.

With license extensions for its three units in hand, Duke Energy’s Oconee Nuclear Station began a digital controls upgrade program in 2006, and in January 2010, AREVA became the first supplier to receive Nuclear Regulatory Commission approval for a safety-related digital instrumentation and controls system.

On August 23, 2011, at 1:51 p.m., a magnitude 5.8 earthquake knocked both units at Dominion’s North Anna Power Station off-line—the first time such an event has occurred in the U.S. After 80 days of extensive evaluation and inspection by plant staff and representatives from the U.S. Nuclear Regulatory Commission, both units were back online. What occurred during those days is a remarkable story.

Data detailing plans for new nuclear reactors worldwide show few effects of the March 2011 Fukushima accident. China and Russia in particular continue to be hot spots for nuclear development, but cost overruns, construction glitches, and ongoing safety reviews are slowing construction projects elsewhere.

The California Public Utilities Commission (CPUC) has opened a formal investigation into the extended outages of Units 2 and 3 at the San Onofre Nuclear Generating Station (SONGS). The investigation will determine whether to remove all costs related to SONGS from the rates of Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E) going forward, and whether to refund SONGS-related costs already collected in rates back to Jan. 1, 2012.

On Tuesday morning, half a day after Hurricane Sandy made landfall in New Jersey, the enormous storm, now being called a superstorm or a post-tropical cyclone, was still causing destruction far inland while as many as 6 million electric customers from Maine to North Carolina and west to Pennsylvania and West Virginia were without power.

Hitachi announced on Tuesday that it had acquired Horizon Nuclear Power in a deal expected to be completed by the end of November. In another example of the global nature of the nuclear business, the Japanese firm purchased Horizon, which was developed by the UK to build new nuclear plants, from German companies RWE and E.ON.

China regards nuclear energy as a critical part of its strategic goal of achieving sustainable economic development while reducing environmental pollution. An analysis by North China Electric Power University predicts that the pace of nuclear power development may slow for a short time as a result of the Fukushima accident, but nuclear power is still a top development priority.

The Clean Water Act Section 316(b) rule changes regarding cooling water intake structures that are expected next year could affect up to 428 power plants, representing 1,156 individual units, according to the Electric Power Research Institute. Depending on plant size and the complexity of the retrofit project, retrofit capital costs could range from very low to over $500 million for large nuclear plants. The power industry total cost is projected to be over $100 billion.
