NuScale Power Achieves Standard Design Approval from NRC for 77 MW SMR

LCG, May 30, 2025--NuScale Power Corporation (NuScale), a leading provider of advanced small modular reactor (SMR) nuclear technology, yesterday announced that it has received design approval from the U.S. Nuclear Regulatory Commission (NRC) for its uprated 77 MW power modules. NuScale states that it remains the only SMR technology company with design approval from the NRC, and the company remains on track for deployment by 2030, with 50- and 77-MW SMR options.

EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

Cook Unit 1 Restart on Schedule, AEP Says

LCG, Nov. 15, 2000--American Electric Power Co. said yesterday that it is on schedule to restart its 1,020 megawatt Cook Unit 1 nuclear power plant by the end of next March, and might even be ready to put the long-idle reactor on line before that.

"We remain on track for the first quarter (of 2001), possibly before, and we continue to make very good progress," an AEP spokesman said. When the company's 1,090 megawatt Cook Unit 2 was returned to service in June, the company said Unit 1 would follow shortly after the first of the year.

AEP's predictions of Cook restarts have become more realistic in recent years. Both units were shut down in September 1997 when dirty ice was discovered in their emergency cooling systems. At that time, AEP said that both units would be back on line by the end of that year.

The restart dates were moved further and further into the future as AEP discovered just how big its ice problem was. Each of Cook's two units has more than 2.5 million pounds of ice held in 1,944 cylindrical baskets that are 40 feet long. The ice got dirty because the baskets needed renovation.

The Nuclear Regulatory Commission has been closely monitoring AEP's progress with the Cook plants and has held regular monthly public meetings at the plant. The next meeting is scheduled for December 4 and AEP may propose a restart date at that time.
