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.

Bonding nature of hydrogen isotopes on the surface of Li2O has been studied with the CRYSTAL92, ab-initio Hartree-Fock calculation code for periodic systems. It was found that the exothermic dissociative adsorption of H2O molecule could occur on the relaxed surface. The adsorption energy for the most stable site was 0.438eV per one H2O. The nature of -OH on the surface of Li2O was also analyzed. Calculation results showed that the stretching vibration of O–H is affected by the chemical species around the -OH.
