The Nuclear Regulatory Commission will hold a regulatory conference Tuesday, May 19, with Vistra Operations Company officials to discuss a preliminary "white" safety finding at Comanche Peak-2.

In a report sent to Vistra Chief Nuclear Officer Ken Peters on April 10, NRC Division of Operating Reactor Safety Acting Director Patricia Vossmar said the finding is a result of an inspection conducted by the NRC at the Glen Rose, Texas, plant from March 22 through April 6. The inspection was a follow-up to an August 2025 incident where a leak rendered a safety chiller in Unit 2, train B inoperable due to low refrigerant pressure.

The Nuclear Regulatory Commission scheduled a meeting with Vistra Operations Company to address a white safety finding at the Comanche Peak nuclear plant. The finding stems from an inspection following a 2025 incident where a refrigerant leak rendered a safety chiller inoperable. This conference provides an opportunity for the licensee to discuss the safety significance and corrective actions related to the equipment failure.
