Abstract
A pressurized tube experiment was conducted on a Russian Fe-16Cr-15Ni- Nb stainless steel in the BN-350 reactor in Kazakhstan. Strain data ar e reported on annealed tubes irradiated to 60 dpa at 480 degrees C and to 20 dpa at 520 degrees C, both at hoop stress levels ranging from 0 to 200 MPa. The strains observed were linear with applied stress, and the void swelling derived from density measurements was clearly enhan ced by stress, an observation confirmed by electron microscopy examina tion. The derived creep coefficients agree well with those found in We stern studies on stainless steels. (C) 1998 Elsevier Science B.V. All rights reserved.
