Gentlemen:
Haddam Neck Plant Millstone Nuclear Power Station, Unit Nos.1 and 2 Response to I&E Bulletin No. 80-21 In reference (1) and (2), Connecticut Yankee Atomic Power Company (CYAPCO) and Northeast Nuclear Energy Company (NNECO), respectively, were requested to take appropriate action in response to I&E Bulletin No. 80-21.
CYAPCO and NNECO have formally initiated the determination of the affected valves (I&E Bulletin No. 80-21, action item (1)) in their respective plants by contacting suppliers of active valves in safety related systems.
CV '.PCO and NNECO have also indicated by telephone to the NRC that a complete response to the Bulletin may well require an effort of a year Once the responses from the valve suppliers are received, a or more.
schedule will be established for an orderly inspection program; until that time it is not possible to accurately estimate a completion date for either CYAPCO's or NNECO's ef forts. The staff should be aware that visual inspection of the valves is not necessarily a simple task.
As an example of one significant complicating factor, many of the valves may be covered with insulation which must be removed.
