SUBJECT:
Waterford SES Unit 3 Docket No. 50-382 Construction Deficiency Report No. 11 Switchgear Breaker Position Switch Operator Defect
Dear Mr. Seyfrit:
As discussed with your Mr. Stewart, the planned modifications of the GE switchgear breaker position switch operators will be delayed due to a slippage in the schedule requirements of the GE technical representative.
We have received the operators on site and expect replacement installation to commence in December. We now expect to be able to complete all work and submit the final report by March 31, 1979.
Yours verv truly, D. L. Aswell DLA/TFG/grf cc. Director Office of Inspection and Enforcement U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Director Office of Management Information and Program Control U. S. Nuclear Regulatory Commission 20555 Washington, D.C.
