SUBJECT:

Special Report 272/2014-008, One Channel of Reactor Vessel Level Instrumentation System (RVLIS) Inoperable Greater Than 30 Days The attached Special Report is being submitted pursuant to the requirements of Salem Unit 1 Technical Specification (TS) 3.3.3.7, which requires that both channels of Reactor Vessel Level Instrumentation System (RVLIS) be operable in Modes 1, 2, and 3. With one channel inoperable, the action statement requires restoration of that channel to operable status within 30 days or submission of a Special Report in accordance with administrative TS 6.9.4.

There are no commitments contained in this letter. Should you have any questions or comments regarding the submittal, please contact David Lafleur of Salem Regulatory Assurance at 856-339-1754.

Sincerely, Site Vice President - Salem Attachment

Attachment LR-N14-0268 Special Report 272/2014-008 Description of Occurrence The Salem Unit 1 Technical Specification ( TS) 3.3.3.7 requires both channels of Reactor Vessel Level Instrumentation System ( RVLIS) to be operable in Modes 1, 2 and 3. With one channel inoperable, TS 3.3.3.7, Action 8 requires the inoperable channel to be returned to operable status within 30 days or submittal of a Special Report in accordance with TS 6.9.4.

On November 19, 2014, while in Mode 4, a leak was discovered on the Train A RVLIS capillary tubing inside containment. As a result of the leak, the tubing was cut and capped near the source of the leak inside containment. This condition renders the Train A RVLIS channel inoperable. Based on the nature of the repairs required, the unit would need to be placed in Mode 5 to make the repairs. As allowed by TS 3.3.3.7, Unit 1 entered Mode 3 on November 20, 2014.

Preplanned Alternate Monitoring Method The current Salem unit 1 operating procedure for RVLIS states that when one or both RVLIS channels are inoperable, the preplanned alternate method of monitoring for inadequate core cooling is that the required channels in Salem Unit 1, TS Table 3.3-11 for both Reactor Coolant System ( RCS) Sub-cooling Margin Monitor ( SCMM) and the Core Exit Thermocouples ( CET) are operable. These channels are currently operable.

Cause of the lnoperability The cause of the inoperability is a result of a leak in the Train A RVLIS capillary tubing inside containment. As a result of the leak, the tubing was cut and capped near the source of the leak inside containment.

Plans to Return to Operable Status The 'A' RVLIS train will be returned to operable status in the next refueling outage

( 1R24) , scheduled for the Spring of 2016.
