By David Wagman Denver, April 23, 2013 — Japan’s Nuclear Regulatory Agency (NRA) is expected to release this July regulations for restarting the nation’s fleet of nuclear generating stations. Much of that capacity shut down following the March 2011 Fukushima nuclear accident. Those nuclear closures threw domestic Japanese and global energy markets into turmoil as […]

Even though the U.S. Nuclear Regulatory Commission (NRC) believes the current 10-mile radiological emergency planning zone around nuclear power plants is sufficient, a Government Accountability Office (GAO) report released last Thursday recommends that a larger zone would improve emergency preparedness for possible radiological incidents “and is consistent with NRC guidance.”

The operator of South Korea’s 23 nuclear power plants said over the weekend that it had separated its internal computer network and plant control systems from the Internet and sealed USB ports in an effort to prevent hacking.

The carbon intensity of the global energy supply has barely budged in more than two decades despite otherwise successful efforts in deploying renewable energy, the International Energy Agency (IEA) warns in an annual report submitted to the Clean Energy Ministerial (CEM) on Wednesday.

The increasing cost of natural gas relative to coal is expected to increase coal’s share of total generation from 37.4% in 2012 to 39.9% in 2013, according to the U.S. Energy Information Administration (EIA) April release of its Short-Term Energy Outlook (STEO). Though that would leave coal’s percentage below its 42.3% share in 2011, it indicates that gas may not be on an inevitable path to overtake a significantly greater share of the generation pie.

Polish utility PGE scrapped plans to build two 900-MW coal-fired power units worth $3.6 billion at a plant near the southwestern city of Opole, citing falling electricity prices and weak demand.

Dr. Ernest Moniz, President Obama’s nominee for the next Secretary of Energy, appears poised for easy confirmation after responding to questions from the Senate Energy & Natural Resources Committee on April 9. His remarks indicated support for, among other things, small modular reactors, carbon capture technology research, and moving forward with the recommendations of the Blue Ribbon Commission on America’s Nuclear Future.

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.”

More than two years after an earthquake and tsunami caused catastrophic damage at Japan’s Fukushima Daiichi Nuclear Power Station, its operator, Tokyo Electric Power Co. (TEPCO), still struggles to ensure stability at the site. In the latest unwelcome development, the site has experienced leaks of contaminated water from storage pools and is running out of space to store radioactive water.

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.
