| Title | Technical Specification Required Shutdown Due to Two Rod Position Indicators (Rpis) Out in One Rod Bank |
| Event Description | At 0408 EST [the licensee] entered into TS 3.0.3 due to an observed RPI B-10 erratic indication. This RPI is in the same bank as currently inoperable F-2 RPI. TS 3.1.3.2 has actions for a maximum of one RPI per bank inoperable. Since there are two [RPIs inoperable] in one bank, and entry into TS 3.0.3 is required.
Power reduction was initiated at 0502. Repairs are currently in progress and [the licensee] anticipates correction prior to completion of the power reduction. The licensee notified the NRC Resident Inspector.
The licensee reports that repairs have been completed to RPI B-10 and it has been returned to service. Technical Specification 3.0.3 was exited at 0625. Reactor power has been returned to 100%. The NRC Resident Inspector will be notified. The R2DO (Ayres) has been informed. |
