Narrative

Report for LER 50-366/1982-088 On August 6, 1982, with the unit in hot standby, a control rod reed switch position indicator was found to be inoperable during the performance of the " Normal Startup" procedure.

This event is contrary to Technical Specification 3.1.3.7 which states that all control rod reed switch position indicators shall be operable.

Continued operation was permitted under a limiting condition of operation (LCO) as per Tech. Spec. sections 3.1.3.7.a.1.a and b.

Section (a) requires that the position of the control rod be determined by an alternate method (full-in indication was functional).

When the unit was brought back up in power, operation was permitted under T.S.

section (b) which permits continued operation if the control rod is moved to a position with an operable reed switch position indicator.

The health and safety of the public were not affected.

This event is non-repetitive.

The cause of this event has been attributed to component failure.

The cause of the failure has not been determined.

An update report will be submitted upon completion of the corrective action.

This action will be completed during the 1983 refueling outage.
