Abstract:

This report describes progress in a program to characterize material properties performance with respect to the structural integrity of light water reactor pressure boundary components. The work is sponsored primarily by the U.S. Nuclear Regulatory Commission. Studies on dynamic fracture toughness are also being conducted on a cooperative basis between the Electric Power Research Institute and NRL. Additional support for the dynamic fracture toughness studies is provided by the Office of Naval Research. This report describes progress in the following areas Warm prestress investigations related to thermal shock of a vessel fracture toughness degradation of commercial weld deposits following low fluence irradiation auger spectrography study on the mechanism of phosphorus contribution to steel radiation sensitivity elastic analysis of three-point bend specimens subject to impact loading and a survey of reactor materials research underway at two foreign laboratories.
