Abstract : The report, covering research for the period 1 August - 31 October 1970, includes: (1) initial radiation damage surveillance results for the MH-1A reactor vessel, (2) development of a reference fluence decrease through a reactor vessel wall, (3) analysis of the fluence gradient in terms in terms of fracture behavior, including fracture extension resistance for the through-wall vessel properties, (4) correlation of Charpy-V and dynamic tear test results for reactor steels after irradiation, (5) true stress-natural strain determinations for several high temperature alloys irradiated in the EBR-II reactor, and (6) the nature of dislocation loop growth during annealing of irradiated vanadium.
