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.

Nuke Corrosion Costs Burden Ohio Plant

LCG, March 26, 2002-Investigations regarding regarding reactor corrosion may keep nuclear plants shut down.

Boric Acid in an Ohio nuclear plant corroded the cap of the reactor, forming a significant hole.

The Nuclear Regulatory Commission (NRC) ordered that 69 pressurized water reactors be inspected after the hole was found in the 25-year-old David-Besse plant. Special attention will be given to the six reactors sharing the same Babcock and Wilcox construction as the David-Besse reactor.

The damaged reactor will take three months to two years to repair, depending on whether or not a new reactor head will need to be constructed. In the meantime the plant will be forced to pay ten to fifteen million dollars monthly to buy power in order to sustain its 7 percent of company FirstEnergy's total energy. Repairs will cost at least $10 million and replacing the head would cost $20 million.

Midwest wholesale power prices for deliveries next summer increased by twelve percent last week, possibly caused by energy traders who fear limited energy supply.

Corrosion has been found in reactor nozzles of other plants, but none of the damage is nearly as serious as that at the David-Besse reactor. Plants and generators anxiously wait for inspectors from NRC to approve their reactors.

Officials say corrosion of this type poses no public risk.
