NRC Completes Safety Review of Construction Permit Application for TerraPower's Kemmerer Power Station in Wyoming

LCG, December 1, 2025--The Nuclear Regulatory Commission (NRC) announced today that the NRC staff completed its final safety evaluation for the application submitted by TerraPower, on behalf of its subsidiary US SFR Owner, to construct the Kemmerer Power Station Unit 1 in Kemmerer, Wyoming. Unit 1 will be the first nuclear project of its kind using the Natrium advanced reactor design. The evaluation concludes there are no safety aspects that would preclude issuing the construction permit.

California County Expands Nation's Largest Rooftop Solar Array

LCG, Dec. 6, 2001--Alameda County (Calif.) plans to expand what it claims to be the "nation's largest rooftop solar electric system" from about 640 kilowatts to 1.14 megawatts. The giant solar array is on top of the county's Santa Rita Jail in Dublin, east of Oakland.

The county said that when completed the system will cover about three acres of the jail's roof and will be the fourth-largest solar photovoltaic system in the world.

"The decision to expand solar electric generation capacity at the Santa Rita Jail was easy because the economics were so compelling," said Alameda County supervisor Scott Haggerty, who is president of the county's Board of Supervisors.

The economics are indeed compelling. The county did not have to authorize any general fund revenues to finance its solar electric generation and energy efficiency projects. Money for the projects come from taxpayer-funded programs of the California Energy Commission and the California Public Utilities Commission.

The county also made use of a low interest rate energy efficiency loan from the Energy Commission.

"Harnessing the sun's power to generate clean on-site electricity is not only a good investment, but it's also a safe way to become more electrically independent and environmentally friendly at the same time," Haggerty said.
