Reactor Primary Coolant System Pipe Rupture Study Method for Detection of Sensitization in Stainless Steel Progress Rpt. No. 45 July-Sept. 1978

摘要

A program is in progress to develop a quantitative method [Electrochemical Potentiokinetic Reactivation (EPR)] for nondestructively measuring the degree of sensitization in Type-30^ and -304L stainless steels. The technique has been extended to characterize weld heat-affected zones and to correlate degree of sensitization with intergranular stress corrosion cracking resistance. Current studies are directed toward establishing procedures for, and qualifying, a technique to obtain EPR measurements in-situ on reactor components in the field.
