LWR (Light Water Reactor) Pressure Vessel Surveillance Dosimetry Improvement Program: PSF (Poolside Facility) Physics-Dosimetry Program.

摘要

The goal of the program is to test, against well-established benchmarks, the methodologies and data bases that are used to predict the irradiation embrittlement and fracture toughness of pressure vessel and support structure steels. The prediction methodology includes procedures for neutron physics calculations, dosimetry and spectrum adjustment methods, metallurgical tests, and damage correlations. The benchmark experiments serve to validate, improve, and standardize these procedures. The results of the program are implemented in a set of ASTM Standards on pressure vessel surveillance procedures.
