SYSTEMATIC EVALUATION PROGRAM Topic IV-I-A: Operation with less than all loops in service PLANT: Oyster Creek Nuclear Power Plant Unit No.1 Discussion The majority of the presently operating BWR's and PWR's are designed to permit operation with less than full reactor coolant flow. If a PWR reactor coolant pump or a BWR recirculation pump becomes inoperative,

' the flow provided by the remaining ' loop or loops is sufficient for

. steady state operation at some definable power level, usually less than full power.

Plants authorized for long term operation with one reactor coolant pump out of service have submitted, and the staff has approved, the necessary ECCS, steady state, and transient analyses. The remaining PWR and BWR licensees have Technical Specifications which require reactor shut-down within 24 h'ours if one of the operating loops becomes inoperable and cannot be returned to operation within the time period.

Evaluation The docketed material for Oyster Creek has been reviewed with respect to operation with less than all loops in service.

Oyster Creek is a five loop General Electric design Boiling Water Reactor (BWR).

In a submittal dated February 5,1976, Jersey Central Power & Light Company (JCP&L) presented an analysis for operation with a single recirculation pump inoperable. The analysis supported n-1 loop operation and concluded that ECCS analyses would not be affected provided that the inoperable pump was not isolated from the system.

The NRC staff reviewed and approved the February partial loop submitted in a safety evaluation (dated February 24, 1976).

In addition the staff issued Technical Specification 3.3.F.1, 3.3.F.2, and 3.3.F.3 which state that operation is permitted with one inoperable recirculation loop provided that the inoperable loop is no.t isolated from the reactor system.

Based on the information reviewed we conclude that Topic IV-I-A:

- Operation with less than all loops 'in service at Oyster Creek is acceptable and complete requiring no facility or Technical Specification changes.
