SUBJECT:

Waterford SES Unit 3 Docket No. 50-382 I Potential Construction Deficiency Report Defective Top Cover Gaskets NAMCO EA-180 LIMIT SWITCHES

Dear Mr. Seyfrit:

As discussed with your Mr. Stewart, we have determined that NAMCO EA-180 limit switches with defective top cover gaskets have not been used on HVAC system components at Waterford 3 SES. We are now in the process of determining if these switches are located in other Waterford 3 SES mechanical systems. We expect to complete this review by January 31, 1980 and will notify you of the results by that date.

Yours very 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 Washington, D.C. 20555 8002200 \
