FROM: Thomas E. Murley, Director Office of Nuclear Reactor Regulation

SUBJECT:

INTENTIONAL ENTRY INTO TECHNICAL SPECIFICATION LIMITING CONDITION FOR OPERATION 3.0.3 This is in response to Region V's memorandum of March 18, 1987, (Enclosure 1) wherein they referred to an inappropriate use of Technical Specification Limiting Condition for Operation (LCO) 3.0.3 by the Palo Verde licensee. It I

was suggested that it might be beneficial for NRR to issue some generic communication to reiterate NRC's position on the intended purpose of LCO 3.0.3 and clarify the NRC's expectation concerning licensee management control of entry into it.

LCO 3.0.3 is not intended to be used as an operational convenience which permits redundant safety systems to be out of service for a limited period of time. Its intended purpose is to provide guidance on the time limits for an

" orderly" shutdown when the individual Limiting Conditions for Operation or ACTION statements in other specifications cannot be complied with. Voluntary entry into LCO 3.0.3 deliberately removes the last echelon of defense against deleterious events by allowing removal of a system from service when its redundant counterpart is already out of service or inoperable. An action such as this would show a significant disregard for plant safety and is unacceptable.

It should also be emphasized that removal of a s only for test, maintenance, or repair purposes. ystem from service is justified On June 4,1987 as part of the short term Technical Specifications Improvement Program we issued Generic Letter 87-09 which, among other things, addresses

==- this subject in a rewritten BASES for LCO 3.0.3 (Enclosure 2). Additionally, we recommend that all Regions increase communication with resident inspectors and plant management on this subject, thereby promoting a heightened awareness by the inspectors, licensee management and plant personnel of the intended limited use of LC0 3.0.3. We believe these actions will be sufficient to address this problem. .. signed bz hMMurley, Direttor Thomas ,E.
