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.

Millstone 3 Nuclear Plant Runs 585 Days at 99.9 Percent

LCG, June 5, 2001As Northeast Utilities' 1,154 megawatt Millstone Unit 3 nuclear power plant coasted down for a refueling outage Saturday, the company said that the once-troubled plant had operated for a record 585 continuous days and had turned in a capacity factor of 99.9 percent over that period.

In the early 1990s, cost-cutting was the by-word at Northeast's nuclear plants, with the result that its Connecticut Yankee plant in Haddam Neck, Conn., had to be permanently shuttered and its three-reactor Millstone complex near Waterford, Conn., was shut down at a cost to the utility of more than a billion dollars.

The nuclear "culture" at Northeast changed in 1997 when Michael G. Morris replaced Bernard M. Fox as chief executive and Bruce D. Kenyon, a no-nonsense former nuclear Navy officer was installed as president of the utility's nuclear operations.

Millstone Unit 1 was adjudged too costly to fix, but Unit 2, an 871 megawatt reactor, and Unit 3 were brought back up to standard and restarted. Together, those two units produced 16.4 billion kilowatt-hours of electricity in 2000, Northeast said.

Last August, Dominion Resources Inc. agreed to purchase Millstone for $1.3 billion. That transaction is expected to be completed sometime in April.
