Abstract : The research program involves a broad study of the effects of nuclear radiation upon materials. The report, covering research for the period, 1 May-31 July 1971, includes: (1) the plastic fracture resistance of thick-section A533-B steel, (2) a radiation resistant weld for fabricating A533-B reactor vessels, (3) the effects of irradiation and temperature on the fatigue properties of A533-B steel, (4) the vacancy condensates produced by laser bombardment, and (5) the low-energy neutron contributions to embrittlement of pressure vessel steel.
