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.

Massachusetts Politicians Request Delay in SeaBrook License Extension

LCG, January 23, 2019--Two U.S. senators and a U.S. representative from Massachusetts jointly sent a letter to the Nuclear Regulatory Commission (NRC) last week opposing the NRC's decision to grant NextEra, the owner of the Seabrook, New Hampshire, nuclear power plant, a 20-year license extension and amendment later this month for the plant.

The NRC had recently announced plans to grant NextEra the extension of its operating license "on or about January 30," together with an amendment to the license regarding the presence of concrete degradation at the plant caused by alkali-silica reaction (ASR), which was discovered in 2009. The politicians requested a delay in the license amendment and renewal until after this summer's Atomic Safety Licensing Board hearing, which would include public input.

A NextEra representative stated, "Since 2011, the Nuclear Regulatory Commission has held more than a dozen public meetings, with the opportunity for members of the community to weigh in. Public meetings are an important part of the NRC's process, and we expect public conversations to continue. License renewal is important for protecting the role of Seabrook Station as a regional asset and a producer of clean, reliable and low-cost electricity for New England."

Commercial operations for the 1,250-MW pressurized water reactor (PWR) began in August 1990. The current license is due to expire March 15, 2030, and the license extension will enable carbon-free, electric generation from the nuclear facility into 2050.
