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.

LCG, November 26, 2025--RWE announced today the commissioning of the Stoneridge Solar project, located in Milam County, Texas. The project capacity is 200 MW of solar power, plus a battery energy storage system (BESS) that provides 100 MW (200 MWh) of battery storage capacity. The BESS improves the supply of short-term, reliable, affordable electricity in ERCOT.

Boric Acid Leak in Texas Reactor Worries Other Plant Owners
LCG, May 1, 2003A routine inspection at a Houston, Texas nuclear plant resulted in the discovery of mysterious and foreboding boric acid residue. After Ohios Davis-Besse nuclear plant suffered a large hole in its reactor head from boric acid-related corrosion, the nuclear industry has stepped up its efforts regarding especially susceptible plants. Although Davis-Besse has yet to return to service, other similarly engineered plants have increased inspections to prevent such dramatic corrosion. However, in the case of the South Texas Project plant, corrosion seems to have occurred in a much more problematic region, the bottom of the reactor. In March, plant inspectors found two small minute boric acid deposits underneath the reactor vessel. While a leak of this type will have no effect on public health, ensuring the safety of the technician responsible for fixing the holes is challenging at best. Beyond mere repair, the finding has worried those who run or own the other 68 U.S. nuclear plants of similar design. Reactor 1 underwent inspections more rigorous than those required by NRC and is a mere 15 years old. If the leaks turn out to be associated with normal wear and tear, the finding would come as bad news all around. Boric acid is used to absorb extra neutrons produced in nuclear reactors. Radiation, high temperatures, and stress (force per area), combined with acidic conditions, can result in the oxidation, or corrosion, of metal, even specially designed alloys like steels. South Texas Project Nuclear Operating Company, which is responsible for daily operation of Reactor 1 as well as a second reactor on-site, has not been able to determine a cause for the deposits and has told the Nuclear Energy Regulatory Commission that the plants reactor will be disassembled in order to investigate the leak further. The reactor has 1,250 megawatts of capacity and was initially shut down for refueling. CenterPoint Energy Inc. and American Electric Power Company, as well as San Antonio and Austin municipal utilities jointly own the plant.
