NEUP CINR-21-24382: Advanced High-Fluence Low-Flux RPV Mechanical Property Models for Extended Life

We propose to further develop accurate models of the mechanical property changes under life-extension conditions in reactor pressure vessel (RPV) steels using reduced order Avrami models, cluster dynamics, and atomistic methods combined with massive comprehensive databases on irradiated steels. The work will provide models critical to extending the life of US PWRs as well as new fundamental insights into flux and fluence effects and sink and precipitate evolution in RPV and related steels.
