Abstract:

The report includes the following 1 a comparison of the response of selected structural steels to irradiation at 550 and 650F to high neutron fluences, 2 the through-thickness Charpy-V notch ductility performance of a 10-12-in.-thick plate of irradiated A302-B steel, 3 an investigation of the effects of oxygen and nitrogen contents on the radiation embrittlement sensitivity of 7-12Ni-Cr-Mo steel at 250F, 4 the notch ductility behavior of irradiated 12Ni-5Cr-3Mo maraging steel weldments, 5 the response of A350-LF1 Modified steel to postirradiation annealing at temperatures in the range of 550 to 590F, 6 the notch ductility behavior of A350-LF1 Modified steel with cyclic 430F irradiation-168 hour annealing, 7 the preirradiation mechanical properties of the MH-1A reactor pressure vessel steel, 8 the notch ductility of several reactor structural steels after irradiation in a heavy water moderated reactor, 9 the modification, installation, and initial operation of a remotely operated, tape-controlled milling machine, and 10 a description of newly acquired remotely operated precision measuring equipment.
