Abstract : The effects of nuclear radiation upon the properties of structural materials are discussed. Data are included on the following: (1) comparison of the asirradiated properties of ASTM Type A350-LFl (Modified) plate and ring forging, (2) effects of various postirradiation annealing treatments on the notch ductility characteristics of ASTM Type A350-LFl steel, (3) notch ductility properties of uranium bearing steels after irradiation, (4) neutron dosage values for the OMRE pressure vessel and grid plate, and (5) preliminary efforts in the Yankee Atomic pressure vessel surveillance program.
