Radiation-Embrittlement Resistance of Advanced NiCrMo Steel plates, Forgings, and Weldments.
Abstract
The promise of selected nNiCrMo steels for advanced reactor vessel applications was demonstrated. Generally superior radiation embrittlement resistance, as well as superior preirradiation transition temperatures (Charpy-V 30-ft-lb index), were observed relative to the performance of A533 plates and welds of current usage. With only two exceptions, the A543 plates and A508 forgings examined showed sufficient resistance to a fluence of 4 x 10 to the 19th power n/sq cm>1 MeV to retain a subzero transition temperature. Weld deposits typically had higher postirradiation temperatures than parent plates.
