RWE Commissions the 200-MW Stoneridge Solar Project in Texas

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.

Oklo and Siemens Energy Sign Agreement to Accelerate Power Conversion System for New SMR in Idaho

LCG, November 19, 2025--Oklo Inc. and Siemens Energy announced today that the parties have signed a binding contract for the design and delivery of the power conversion system for Oklo’s Aurora-INL (Idaho National Laboratory) nuclear small modular reactor (SMR). The agreement authorizes Siemens Energy to begin engineering and design work to expedite procurement of long-lead components and to initiate the manufacturing process for the power conversion system. Oklo’s expertise in advanced fission technology will be combined with Siemens Energy’s extensive industry experience with steam turbine and generator systems, with the ultimate goal of generating carbon-free, reliable electricity.

NRC Asks Nuclear Plant Operators to Check Cooling Nozzles

LCG, Aug. 6, 2001-- The Nuclear Regulatory Commission on Friday issued a bulletin seeking information from several nuclear power licensees regarding the structural integrity of cooling nozzles which penetrate the reactor pressure vessel of pressurized water reactors.

Recent discoveries of cracked and leaking nozzles at two reactors prompted the request, the NRC said, because they have raised concerns about the structural integrity of reactor penetration nozzles inthe top of reactor pressure vessels at pressurized water reactors throughout the industry.

It's the direction the cracks go that has the agency concerned. During refueling outage inspections, some nozzles have been found with lengthwise cracks. These were not considered a safety problem and the nozzles were replaced during the outages. Earlier this year, however, cracks that went part way around the nozzles were found at the two reactors.

In addition to providing coolant to maintain the reactor coolant system pressure boundary, the nozzles also serve as guides for control rods which pass through them at the top of a reactor vessel head. The control rods are moved in and out of the bundles of fuel rods to regulate the level of a reactor's output.

The NRC said "cracking of the control rod drive mechanism nozzles represent a degradation of the primary reactor coolant system boundary, and hence, is potentially safety significant."

The agency said it is requesting information from pressurized water reactor licensees to determine whether current inspection practices are adequate and whether any additional regulatory response by the agency is necessary.

The bulletin requires that pressurized water reactor operators submit a written response indicatingwhether the requested information will be submitted within the required 30-day time period. NRClicensees unable to satisfy this requirement will have to submit a written description of any alternativecourse of action they propose to take, including the basis for its acceptability.
