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.NRC FORM 366 (6-1998)
