The Nuclear Regulatory Commission (NRC) on Tuesday urged owners of 62 nuclear power plants in the Central and Eastern U.S.—facilities housing 96 of the nation’s 104 commercial nuclear reactors—to reevaluate seismic hazards using a new seismic model and information from a recent report.

A failed electrical insulator at a switchyard at Exelon Generation Co.’s two-unit Byron nuclear plant in Lisle, Ill., has been blamed for the loss of offsite power on Monday morning that automatically shut down Unit 2 and forced Exelon to declare an “Unusual Event.”

The 15-member Blue Ribbon Commission (BRC) appointed by Energy Secretary Steven Chu in January 2010 to provide comprehensive recommendations for a long-term solution to managing and disposing the nation’s spent nuclear fuel and high-level radioactive waste released its much-anticipated final report last week.

A federal district court judge on Tuesday ruled that the Rural Utilities Service (RUS), an arm of the U.S. Department of Agriculture (USDA), must complete an environmental impact study (EIS) before any approvals or other major federal action can be taken on the $2.8 billion expansion at Sunflower Electric Power Corp.’s coal plant in Holcombe, Kansas. The ruling may delay construction of the 875-MW plant, a politically controversial project in the Kansas Legislature.

A high-voltage electricity panel arc reportedly sparked a brief fire at the 100-MW Nacogdoches Power, LLC biomass power plant under construction in Sacul, Texas, and sent two workers to hospital in critical condition on Tuesday.

Federal Energy Regulatory Commission (FERC) on Monday released a white paper that seeks comment on its proposals to “provide a fair, timely and transparent process” for FERC to advise the Environmental Protection Agency (EPA) on requests for extension of time to comply with its Mercury and Air Toxics Standards rule.

The Department of Energy (DOE) on Friday announced a draft funding opportunity to establish cost-shared agreements with private industry for the design and licensing of small modular reactors (SMR), targeting their deployment by 2022.

A federal judge last week ruled that Entergy’s Vermont Yankee nuclear power plant—Vermont’s only reactor—can remain operating beyond a state-mandated shutdown deadline. State laws that would force the closure of the 40-year-old plant, which recently garnered a 20-year operating license extension from the Nuclear Regulatory Commission (NRC), are preempted by federal law, the judge said.

In response to a recent decision by a federal court judge that reinstates rules stayed by the Environmental Protection Agency (EPA) in early 2011 and that govern hazardous air pollutant standards for industrial boilers and commercial and industrial solid waste incinerators—so-called Boiler MACT rules—EPA Administrator Lisa Jackson said the agency was committed not to enforce those standards until April, when a new revised suite of boiler standards will be finalized.

Over the next two decades, the U.S. power profile will be markedly different as generation from coal declines, natural gas power and renewables surge, and nuclear generation decreases slightly, said the Energy Information Administration (EIA) in its early release version of the Annual Energy Outlook 2012 on Monday. The full report, scheduled to be released this spring, presents updated projections of U.S. energy markets through 2035.
