IRRADIATION EFFECTS ON REACTOR STRUCTURAL MATERIALS.
Abstract
The research program of the NRL Metallurgy Division, Reactor Materials Branch, is devoted to the determination of the effects of nuclear radiation upon the properties of structural materials. The overall program is sponsored by the Office of Naval Research, the U. S. Atomic Energy Commission, and the Army Nuclear Power Program. Since research findings which apply to the objectives of one sponsoring agency are also of interest to the others, the overall program progress is reported herein. This report, covering research for the period 1 May-31 July 1968, includes the following: (1) irradiation response of a 4-in. A533-C, Class 2, submerged arc weldment, (2) relative 550F irradiation response of a heavy section A533-B electroslag weldment, (3) special A533-B steel heat for variable radiation embrittlement studies, (4) thermal stability evaluation of Ni-Cr-Mo weld deposits, (5) thermal stability evaluations of 12Ni-5Cr-3Mo maraging steel plate at 550, 650, and 740F, (6) long-term irradiation of pressure vessel steels in the Big Rock Point Reactor, (7) plate directionality characteristics of irradiated LaCrosse reactor pressure vessel steel, and (8) preliminary study of the irradiation response of A537 Grade B steel at less than 250F.
