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 February-30 April 1968, includes the following 1 controlling the radiation embrittlement sensitivity of Ni-Cr-Mo weld deposits by varying their chemical composition, 2 influence of prior temper embrittlement on the irradiation response of Ni-Cr-Mo steel, 3 relative 550F irradiation response of base plate, Weld metal, and weld heat affected zone of a 7-12-in.-thick A533-B Class I production weldment, 4 drop weight NDT versus Charpy-V energy absorption level in 6-38-in. Type A533-B Class I and II steel plate, and 5 mechanical properties evaluation of PM-2A reactor pressure vessel steel. Author
