Abstract
A problem of current concern in the design of liquid-metal cooled, fast breeder reactors (LMFBR) for commercial power generation is the volumetric expansion of structural components due to the agglomeration of vacancies produced during irradiation. Present plans call for LMFBR fuel cladding and major structural components to be fabricated of an austenitic stainless steel; with operating temperatures and fuel cycles now anticipated, projected values of the volumetric expansion in fuel clad at the end of a fuel cycle are as high as 10-12%. The attainment of such fluences in present test reactors is costly and time-consuming, requiring an irradiation time of some 4-5 years.
