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.
Uranium Chemistry Tutorial
December 8, 2020|10:30AM–12:00PM (11:30AM–1:00PM EST)
Available to 2020 ANS Virtual Winter Meeting Attendees
ANS Members, please log in to watch this webinar.
This is part four of a nine-part tutorial series exclusively available to 2020 ANS Winter Meeting attendees.
Examples where chemistry has unexpectedly impinged (or might have impinged) on criticality control are explored.
Case 1: How poor engineering altered the chemistry of a dissolver system and caused an unexpected criticality hazard… or how a lack of engineering know-how fooled the chemists.
Case 2: How a criticality safety improvement made things less safe as chemistry triumphed over physics.
Case 3: How chemistry fooled even the chemists.
