Dear Sir:

Subject:

Oyster Creek Nuclear Generating Station Docket No. 50-219 Containment Venting and Purging During Normal Operation By letter dated September 27, 1979, the Nuclear Regulatory Commission (NRC) requested that Jersey Central Power S Light Company (JCPSL) commit to an expedited valve qualification program for containment vent and purge valves.

It is JCPSL's intention, through a consultant, to initiate such a prograa. Initial contact has been made with some of the valve manufacturers, and it is expected that the actual testing of valves will commence April or May of 1980 depending on the availability of the hardware and facilities to do such testing. In parallel with this effort, a cost benefit analysis is being conducted to determine if it would be more suitable to replace some or all of the containment vent and purge valves.

By letter dated October 23, 1979, the NRC requested that JCPSL commit on an interim basis to the guidelines provided as an enclosure te that letter.

It is JCPSL's intention to follow the interim position for containment purge and vent valve operation provided by the October 23, 1979 lette.'. In regard to the requirement of the interim guidelines that all valves greater than 3" nominal diameter must be qualified for use or not be used unless the reactor is in cold shutdown or the refueling mode, it is our intention to limit the opening of these butterfly valves to 30* or less until such time as the valves are demonstrated to be fully qualified or replaced with fully qualified valves.

If you have any questions regarding this matter, please feel free to
