Abstract

The results of corrosion damage to the surface of fragments of the SFA cover after neutron irradiation in a BN-350 reactor and subsequent “wet” storage are presented. The relative value of the deflection of the cover fragments as a result of radiation swelling and creep of fuel assemblies was determined.

Keywords

BN-350 reactor, SFA, “wet” storage, ferritic-martensitic steel, neutron irradiation, damaging dose
