The service background to the intergranular stress corrosion cracking (IGSCC) problem in boiling water reactors (BWRs) is summarized in order to bring the problem into focus, and the technical background to the basic phenomenon is given. The possibility of preventing SCC by the addition of inhibitors stable up to BWR temperatures is investigated as an exploratory study. In the past there have been five systems (combinations of alloy and environment) in which the use of inhibitors has been proven so effective that it has advanced to extensive engineering utilization without requiring modifications of alloy, reductions of stress, or other changes in the environment. Unfortunately these systems are not related to the BWR IGSCC case, as far as is known. The finding of inhibitors for these five disparate systems clearly implied a justification for looking for a similar simple solution to the BWR IGSCC problem.
