In a preliminary finding released on Wednesday, staff at the Nuclear Regulatory Commission (NRC) found that Southern California Edison’s (SCE’s) request for a license amendment that would allow limited operations at San Onofre Nuclear Generating Station (SONGS) this summer, does “not involve an increased risk of an accident or create the possibility of a new or different accident from those previously evaluated for its license.”

An accident at Entergy’s Arkansas Nuclear One station near Russelville, Ark., left one worker dead and eight injured Sunday morning. The accident involved the 836-MW Unit 1, which was in a refueling and maintenance outage at the time. The 987-MW Unit 2 was operating but tripped offline and was reported to be in a stable mode. No nuclear material was released.

Apparently, deciding that half a loaf is better than none, Southern California Edison (SCE) on Monday submitted a draft proposal for a voluntary license amendment to the Nuclear Regulatory Commission (NRC) for the troubled San Onofre Nuclear Generating Station (SONGS), in hopes of salvaging its plan for a five-month limited-power restart test. The move appeared to be in response to pressure from local groups seeking to keep the reactor shut down.

Three workers were injured by an arc flash while working in the switchyard at the Callaway Energy Center in Missouri on April 2. Ameren Missouri said the accident, which happened outside the nuclear plant’s protected area, did not affect power generation.

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 18th and 19th chapters, “The Great Uranium Conspiracy” and “Breeding at the Turkey Farm,” the final two chapters of the “False Scarcity and Fools for Fuels” section.

Nuclear power generation is well established, but efforts worldwide to develop permanent disposal sites for highly radioactive waste remain nascent at best. If this were a horse race, you’d have to say the smaller horses are winning.

NuScale on Wednesday announced it would seek federal funding to accelerate deployment of the company’s small modular reactor technology, saying it would submit a letter of intent in response to a funding opportunity announcement (FOA) announced by the Department of Energy (DOE) earlier this month.

The Nuclear Regulatory Commission’s (NRC’s) Atomic Safety and Licensing Board (ASLB) on Tuesday rejected challenges by environmental groups to Progress Energy’s application to license two new nuclear plants in Levy County, Fla.

Southern California Edison (SCE) on Friday released a new technical evaluation that concludes steam generators at its San Onofre Nuclear Generating Station (SONGS) Unit 2 can safely be operated at 100% power. The evaluation reinforces a more conservative plan proposed by the company to federal regulators to operate the unit, which has been shut down since January 2012, at 70% for five months.

The Nuclear Regulatory Commission (NRC) on Tuesday delayed approving a recommendation made by technical staff that calls for upgrades or replacements of "hardened" venting systems at the nation’s 31 Mark I and Mark II boiling water reactors (BWRs), giving staff a year instead to assess other options and produce a "technical evaluation" on the proposal.

Responding to a recent claim by the Nuclear Regulatory Commission (NRC) that the Entergy’s Palisades nuclear power plant is at risk of pressurized thermal shock., the Louisiana-based company said the plant "is a safe and secure facility [and has a] license to operate … through 2031."

On the second anniversary of the 9.0-magnitude Great Tohuku Earthquake that killed more than 25,000 people and set off the worst nuclear disaster in 25 years, Tokyo Electric Power Co.’s (TEPCO’s) devastated Fukushima Daiichi Units 1 through 4 were in cold shutdown and set to be abolished. All Japan’s nuclear reactors remain shuttered for safety inspections, and the rattled nation has yet to finalize a future energy roadmap. Meanwhile, as panelists at the IHS CERAWeek noted, the world’s global nuclear sector seems to have made a slow but determined recovery.

On Monday, the Department of Energy issued a new funding opportunity announcement designed to help U.S. industry design and certify innovative small modular nuclear reactors (SMRs). This follow-on solicitation to the cost-share agreement with Babcock & Wilcox for its mPower SMR technology, announced in November 2012, is open to other companies and manufacturers and is focused on furthering SMR efficiency, operations, and design.

The Environmental Protection Agency (EPA) estimates final regulations curbing greenhouse gas (GHG), mercury, and air toxics emissions from new sources could appear in the Federal Register over the next six weeks. Also forthcoming are final cooling water intake rules and proposed effluent guidelines. The coal ash rule, which has no target date for a final rule, may not be issued this year, the agency said.

The Nuclear Regulatory Commission (NRC) on Monday denied a petition from Unistar Nuclear Operating Services to review an August 2012 decision by the NRC’s Atomic Safety and Licensing Board (ASLB) that found the company was ineligible to obtain a construction and operation license (COL) for its proposed—and then abandoned—Calvert Cliffs 3 EPR because it was completely foreign-owned.

Bill Gates didn’t mince words last night when sharing with the IHS CERAWeek crowd his thoughts about public support for basic scientific research in the United States.

China will reduce the nation’s carbon emissions and energy use per unit of gross domestic product (GDP) by at least 3.7% this year and perform trials for a carbon-trading program, China’s National Development and Reform Commission (NDRC), said in a report on Tuesday. The country would also make "greater efforts to conserve energy" and "reduce the discharge of major pollutants," it’s top economic planner said.

The U.S. Court of Appeals for the D.C. Circuit last week reopened and set a relatively expedited briefing schedule for a case in which several states and nuclear utilities have claimed collection of a nuclear waste fee by the Department of Energy (DOE) is unlawful.

GE–Hitachi division Global Laser Enrichment (GLE) has reportedly submitted a nonbinding proposal to establish an additional uranium enrichment facility at the Department of Energy’s (DOE’s) Paducah enrichment site in Kentucky.

Construction of a $310 million repository about 250 meters below Earth’s surface for low- and intermediate-level radioactive waste from the operation and future decommissioning of Hungary’s power plants reached a significant milestone at Bataapati.

Japan’s scramble to replace generation lost from nuclear power plants that were shuttered after the March 2011 Fukushima Daiichi nuclear accident has forced it to rely on pricey imports of fossil fuels—and soaring energy costs are hammering the world’s third-largest economy.

Southern California Edison now expects the Nuclear Regulatory Commission to decide in late April or May whether or not the 2,300-MW San Onofre Nuclear Generating Station (SONGS) Units 2 and 3 may restart in time for this summer’s demand season.

Nuclear power will play a significant role in the nation’s energy future, though a nuclear expansion will be hindered by several factors—foremost among them low natural gas prices and a lack of a comprehensive national energy policy, Dominion Chair, President, and CEO Thomas Farrell II told attendees at the Platts Nuclear Energy Conference in Washington, D.C., on Wednesday.

An EPR reactor under construction by an AREVA-Siemens consortium in Finland may not start operating until 2016, two years later than its revised start date in 2014, Finnish utility Teollisuuden Voima (TVO) said on Monday. Construction of the Olkiluoto 3 (OL3) unit began in May 2005, and the new possible start date could put it eight years behind its initial schedule.

The beleaguered Crystal River Nuclear Plant in Citrus County, Fla.—which has been in shutdown and offline since late 2009 due to damage to its containment building—is to be retired, Progress Energy Florida announced on Tuesday.

Progress in electronics and information technology has created incentives to replace traditional analog instrumentation and control (I&C) systems in nuclear power plants with digital I&C systems, or systems based on computers and microprocessors. About 40% of the world’s operating reactors have been modernized to include at least some digital I&C systems, according to the International […]
