philadelphia, Pennsylvania 19101

Gentlemen:

Subject: Special Inspection 50-352/85-43

This refers to the special inspection by Mr. E. M. Kelly on November 1 - 6,

and November 13 and 14, 1985 at the Limerick Generating Station, Limerick,

Pennsylvania. The inspection consisted of a review of the circumstances sur-

rounding the discovery of both Emergency Service Water (ESW) system Loop B pump

discharge valves locked in a throttled position at 8 p.m. on October 31,1985.

This inspection also addresses the discovery of an ESW Loop A pump discharge

valve in a fully open but unlocked condition on November 14, 1985. The findings

of this inspection were discussed with Mr. G. M. Leitch and other members of

, -your staff.

We conclude from the findings of this inspection that certain weaknesses exist

with respect to your administrative control of manually operated valves.

Specifically, the ability to more positively identify the position of a manual

valve, and the methods utilized to independently verify the correct position of

such valves, require your management attention. Both ESW system loops were

available, and apparently capable of delivering sufficient design flow to the

required essential equipment, so that the impact of these instances on system

operability and reactor safety was minimal. However, even though both instances

were found and corrected by your operations staff, we are concerned that the

valves in question remained' undetected for an indeterminant time in a condition

other than.the required locked and fully open position. In your response to

Appendix A you are requested to provide a description of your actions taken and

planned relative to the adminstrative control of manually operated valves.

A violation of NRC requirements is cited in Appendix A and categorized under

the NRC Enforcement Policy, 10 CFR 2 Appendix C (49 FR 8583), March 8, 1984.

A reply is required and should be prepared in accordance with Appendix A.

Your reply to Appendix A is exempt from the Office of Management and Budget's

clearance procedures under the Paperwork Reduction Act of 1980, PL 96-511,
