none needed This specification is implied and the operability of RC Pumps 4.4.1.2.2 and is a part of the routine operator shift and daily checks.
3.4.1.3 3.1.1.2.a. 3.4.2 The THI-l specifications requirn OTSG operability when greater 3.1.1.1.c, 3.3.1.4 than 250 F and require DIIR or RCP operation during deboration.
and 3.3.2 Plant procedures are being revised to address UliR system operability when greater than 250 F as well as during cold shutdown. With respect to operability of RC and DilR pumps / loops during cold shutdown, it should be noted that: (1) The RC pumps can only he operated under certain pressure conditions and are therefore not immediately available; (2) With the RC loops unavailabic, (as above) per the NRC prepc4cd specification, no DllR loop maintenance could be performed (without entering a refueling mode per spec. 3.9.8.2)*.
The requirements of the action statements are, however, covered by TMI-1 specifications 3.4.2, 3.3.1.4 (considering the definition of operability), and 3.1.1.1.c.
We agree that DilR system downtime should be minimized.
(We do not believe that it is appropriate to place this philosophy in Technical Specifications.) This is based on the slow response of the RCS under cold shutdown conditions and the variety of methods (OTSG with natural circulation, IIPI biced and feed, and restoration of RC pumps, etc.) which can be made availabic for core cooling long before a core integrity concern could exist due to insufficient cooling or core uncovery.
- 1his involves a RV head lift which is believed to be a greater risk than the reduced DilR system availability.
