0010U ANTICIPATE MAJOR STEAM GENERATOR REPAIRS IN ANY OF YOUR UNITS IN THE NEXT FIVE YEARS, AND IF SO HOW MUCH WOULD THESE REPAIRS COST, PLEASE SPECIFY.
In 1983, we expect a major outage to modify our model D-3 Westinghouse preheat steam generators.
This work will be performed under warranty.
- Westinghouse plugged one tube prior to delivery of the steam generators and plugged two more tubes for instrumentation purposes.
SCE&G plugged five tubes as a result of pre-initial criticality multi-frequency eddy current inspection.
