Structural integrity of water reactor pressure boundary components. Progress report ending 31 August 1977

Technical Report ·
OSTI ID:6433258
This report describes research progress in a continuing program to characterize materials properties performance with respect to structural integrity of light water reactor pressure boundary components. Progress for this reporting period is summarized in the following areas: evaluation of critical factors in crack growth rate studies in a pressurized water reactor environment; irradiation and postirradiation (annealing) heat treatment study of the toughness of pressure vessel steels having a low upper shelf level; exploratory investigation of notch ductility changes in A508-2 forgings; compositional variables affecting upper shelf toughness; and investigation of warm prestress phenomenon as a means to limit crack extension in a vessel during a loss-of-coolant accident.
