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.

Quad Cities 1 Completes 21-Day Refueling Outage

LCG, Nov. 6, 2000--Exelon Nuclear said it had set a record with a 21-day refueling outage at the 810 megawatt Quad Cities Unit 1 nuclear power plant, but it wasn't a record for Commonwealth Edison Co. or the utility's Nuclear Generation Group.

ComEd and its nuclear group have a couple of 17-day refueling outages under their belts but now that ComEd's parent, Unicom Corp., has merged with Peco Energy Co. to form Exelon Corp. a lot of names have changed and everybody gets to start over.

In the mid-1990s, ComEd had a half-dozen of the worst nuclear plants in the United States, but since former U.S. Navy submarine commander Oliver Kingsley came on board in 1997 as president of the newly formed Nuclear Generation Group the utility's fleet of 10 reactors has become an industry leader for reliability, efficiency and safety.

Pretty much the same thing happened at Peco when Corbin A. McNeill assumed the watch in its nuclear generation operations. McNeill, also a former submarine captain, instilled a blend of the Admiral Rickover nuclear ethic and sea service leadership to turn Peco's nuclear operations around. He became chairman, president and chief executive of Peco and is now co-chairman of Exelon along with Unicom's John Rowe.

While 20 days, 17 hours and 26 minutes isn't bad, even by ComEd's standards, it didn't set a record when the reactor went back on line late Friday. The unit will reach full power in a day or two, Exelon Nuclear said.

Before shutting down to refuel on October 14, Quad Cities Unit 1 had operated continuously at 100 percent of capacity for one year, four months and three and one-half weeks. No coal-fired or gas-fired power plant can do that.
