- Boric acid corrosion and stress corrosion cracking are serious risks in stainless clad RPV pressure vessel steels, and both are influenced by residual stresses from the strip cladding process and differing thermal and mechanical properties of the two alloys. This paper addresses the important issue of accurate measurement of residual stresses at the alloy interfaces through the 150mm RPV wall. Measurements use deep-hole drilling or neutron diffraction, both of which experience difficulties at the critical interface. This paper is the first to have applied both techniques to a large sample of clad RPV pressure and to hence determine measurement errors.
