Abstract (Limit to 1400 spaces, I.e., approximately 15 single-spaced typewritten lines) (16)

On November 22, 1998, during a review of Technical Specification (TS) surveillance requirements for the engineered safety feature actuation system instrumentation by engineering, it was discovered that in Modes 3 and 4 the, reactor trip signal from a manual initiation of a safety injection (Sl) had not been verified in accordance with TS 4.3.2.1.1, Table 4.3-2, Item 9.a. The TS requires the Sl tests be performed for Modes 1, 2, 3 and 4 on a refueling frequency. Normally'during preparations for unit restart from refueling, the reactor trip breakers are required to be open in Modes 3 and 4 for other TS surveillance testing. The tripping of the reactor trip breakers from manual Sl initiation cannot be verified with the reactor trip breakers open. Therefore the reactor trip portion of the manual Sl test has not normally been performed for Modes 3 and 4. In accordance with 10CFR50.73(a)(2)(i)(B), this interim LER is being reported as a condition prohibited by the plant's TS.

Maintenance is currently evaluating the significance and cause of this event. Corrective actions will be developed based on the results of the evaluation. It is anticipated that an update to this LER will be submitted by January 12, 1999.
