Dear Mr. Stolz:
This letter is to provide formal notification of delays in implementing two NUREG-0737, Clarification of TMI Action Plan Requirements, items at the Davis-Besse Nuclear Power Station, Unit No. 1.
As discussed with your staff, our best efforts will not accomplish all the tasks originally scheduled for the upcoming outage.
Specifically, the items related to Sections II.F.1.2 and II.B.3 of NUREG-0737. The station vent stack monitor, part of the II.F.1.2 modifications, has been delayed until after the outage. This delay is due to the extremely large manpower effort (estimated 35,000 manhours) required for this modification.
Imposing this activity concurrent with the refueling outage would interfere with other significant THI Requirements actually needing outages to complete. As a result, installation has been deferred until after the outage work schedule is complete.
Complete installation of the reactor coolant sampling system of NUREG-0737 II.B.3, is also being deferred. This is a new remotely operated post-accident reactor coolant. sampling system.
Although all hardware requiring outage work will be available and will be installed as planned, the actual operators' panel will not be delivered prior to the scheduled startup date. As a result, the reactor coolant post-accident sample system will not be functional as previously scheduled.
In both of the above cases, all outage required work is to be completed such that the systems can be expeditiously placed into operation after the refueling without additional outages. These systems will be completed prior to the end of 1982.
In both cases, interim systems are currently operational and will remain so until the upgraded systems are operational. These interim systems have been recently reviewed during a two-week NRC Emergency Planning Appraisal.
