    Abstract

    A utility perspective on evaluating and managing radiation embrittlement of pressure vessels is presented in this paper. Included are observations and experiences gained from pressure vessel surveillance capsule programs, and activities on flux reduction through the use of low-leakage core-loading patterns. Also included are pressure vessel embrittlement considerations relating to plant rerating and plant life extension.
