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.

Target design, fabrication and handling are central to the design of a Laboratory Microfusion Facility (LMF). Both direct and indirect drive target designs are being considered. This paper will address the target issues for the LMF concept, for the case of direct drive targets. Current direct-drive designs call for uniform liquid DT layers to be contained in a low density hydrocarbon foam shell at 20–25°K, or uniform solid DT layers to be created on the interior of a solid shell at about 19°K. A conceptual plan for LMF target fabrication is presented which addresses many of the issues raised by this new generation of ICF targets. Since these targets will require a cryogenic environment until they are imploded, solutions to a number of problems including temperature stability, fill methods for various target designs, tritium supply, target transport, and target alignment must be integrated into a single cryogenic system which maintains the target over its lifetime. The simultaneous solution of all these issues will require a complex facility capable of integrating technologies ranging from foam chemistry to novel cryogenics. This paper outlines the requirements on such a facility as well as many solutions under consideration.
