Multistructural examination of low activation ferritic steels following irradiation in ORR at 330 and 400 degrees C to ~ 10 dpa

Abstract

Microstructural examinations are reported for a series of low activation steels containing Mn following irradiation in the Oak Ridge Reactor at 330 and 400°C to ~10 dpa. Alloy compositions included 2% Cr, 9% Cr and 12% Cr steels with V to 1.5% and W to 1.0%. Results include compositional changes in precipitates and microstructural changes as a function of composition and irradiation temperature. It is concluded that temperatures in ORR are on the order of 50ºC higher than anticipated.
