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.

Hole Found in the Ohio Nuke

LCG, March 12, 2002-Federal inspectors were surprised to find a hole in an Ohio nuclear plant reactor cap. The hole has been plugged with a non-corroding layer and is no threat to public safety.

Very low concentrations of boric acid produced during nuclear fission ate away at the substantial protective cap that shields the reactor vessel. The hole was found during routine maintenance after similar corrosion was found in control rod nozzles, five of which were cracked.

Plant operator FirstEnergy says that the hole is unusual and unexpected but would have posed little hazard if it had penetrated the entire cap. Radioactive steam would have escaped into the reactor containment building, and even if the steam made its way outside of the building it would reportedly have little effect upon the public. No speculation was made regarding the effects of corrosion on other parts of the nuclear reactor, but FirstEnergy intends to replace the reactor head in 2004.

The plant, located near Lake Erie about 25 miles from Toledo, will remain shut down for at least a month.
