2025 annual assessments out for U.S. reactors
The Nuclear Regulatory Commission has released its 2025 annual performance assessments of the country’s 95 operating commercial nuclear reactors. And of the 95 reactors, all but five earned the highest marks.
Nuclear power plant assessments can fall under one of five categories: Licensee Response, Regulatory Response, Degraded Cornerstone, Degraded Performance, and Unacceptable Performance. Ninety reactors fell under Licensee Response, the highest performance category in safety and security. Plants that achieve this level of performance are subject to a Reactor Oversight Process (ROP) baseline inspection.

This Education in Thermal Hydraulics Panel is the second in a series of panels focused on understanding and improving existing practices within thermal hydraulics related education, best practices, and tactical methods that may be feasible to deploy as a nuclear community to serve as resources for all ANS members. The goal of this second educational in thermal hydraulics panel is to reflect on the outcomes of the first which resulted in the understanding that a suite of resources should be developed for the community. The panel will also involve discussions on progress made on these efforts while providing discussion and dialogue through examples of success.
