SUBJECT:
Waterford SES Lhit No. 3 Docket No. 50-382 Final Report Status for Significant Construction Deficiency No. 5 "LPSI Pumps Impeller Shaf t Pataining Mechanism Failure"
REFERENCE:
- 1) LP&L Telecon discussion with NRC dated July 18, 1978, reporting LP&L Incident No.14
- 2) LP&L letter LPL 9379 to NRC dated August 17, 1978
Dear Mr. Seyf rit :
This is to advise you that submittal of the final report for subject deficiency will be delayed due to additional time required for completion of corrective action. Installation of the i=peller locking device modification kit was completed for one LPSI pu=p, and installation of same on the second LPSI pump has been rescheduled for completion in April, 1980.
Submittal of the final report for this deficiency will not be accomplished until May 1, 1980, rather than January 31, 1980, as previously identified in Reference 2.
Yours very truly, f& $M D. L. Aswell 9g Bon 50 JMR:dsk cc: 1) Director 2) Director Office of Inspection & Enforcement Office of Management U. S.
