Corrosion experience with the secondary side of steam generators in the United States
- Dominion Engineering, Inc., McLean, VA (United States)
This paper reviews experience with secondary side corrosion in pressurized water reactor (PWR) steam generators in the US. It describes the history of the various types of corrosion that have occurred on the secondary side, and the actions that have been taken by the industry to address them. It describes the current situation, indicating that denting and pitting are largely controlled, but that intergranular attack/stress corrosion cracking (IGA/SCC) is an increasingly severe problem. Factors possibly involved in the worsening IGA/SCC are discussed, as are the results of failure investigations the results of application of various remedial actions. Conclusions and recommendations regarding needs for further research directed at resolving unknowns with regard to causes and remedial actions are provided. 74 refs.
