This event is reported in accordance with 10 CFR 50.73 (a)(2)(i)(B), "Any operation or condition which was prohibited by the plant's Technical Specifications.... "

CAUSE OF EVENT

The cause of the 11 SG, Channel 2 drifting indication and subsequent failure was due to failure of the 1 L T519 level transmitter. The completion of the past functionality review was delayed and not completed until February 12, 2015 due to lack of timeliness guidance in the past functionality evaluation process.

SAFETY CONSEQUENCES AND IMPLICATIONS

The safety significance of this event is minimal. This event did not result in any offsite release of radioactivity or increase of offsite dose rates, and there were no personnel injuries or damage to any other safety-related equipment. The remaining two 11 SG level protection channels were functional and their SG LO-LO Level protective trip functions remained capable of generating a reactor trip signal during the time in which 1 L T519 was inoperable.

SAFETY SYSTEM FUNCTIONAL FAILURE A review of this event determined that a Safety System Functional Failure (SSFF) as defined in Nuclear Energy Institute (NEI) 99-02, Regulatory Assessment Performance Indicator Guideline, did not occur. This event did not prevent the ability of a system to fulfill its safety function to either shutdown the reactor, remove residual heat, control the release of radioactive material, or mitigate the consequences of an accident.

PREVIOUS OCCURRENCES

A review of Salem Unit 1 and 2 Licensee Event Reports for the previous three years identified no other

similar events

CORRECTIVE ACTIONS

1.

1 L T519 was replaced and tested satisfactorily on March 27, 2015.

2.

The removed 1 L T519 has been sent to the manufacturer for failure analysis.

3.

Guidance will be added to the engineering technical evaluation procedure for past operability and functionality reviews to be completed within 45 days from the discovery date.

COMMITMENTS

This LER contains no regulatory commitments.
