~PSEG Nuclear LLC JUL 1, 2 2012 LR-N12-0229 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Salem Generating Station, Unit 1 Facility Operating License No. DRP-70 NRC Docket No. 50-272

Subject:

Special Report 272/12-003-00, pursuant to the Requirements of Salem Unit I Technical Specification (TS) 3.5.2, Action b, for SI Accumulated Actuation cycles to date.

This Special Report is being submitted pursuant to the requirements of Salem Unit I Technical Specification (TS) 3.5.2, Action b. TS 3.5.2 Action b states:

"In the event the ECCS is actuated and injects water into the Reactor Coolant System, a Special Report shall be prepared and submitted to the Commission pursuant to Specification 6.9.2 within 90 days describing the circumstances of the actuation and the total accumulated actuation cycles to date."

DESCRIPTION OF OCCURRENCE On April 30, 2012, Salem Unit 1 was operating in Mode 1 at 100% Rated Thermal Power. Instrument and Control technicians were performing a functional surveillance on turbine first-stage pressure transmitter 1 PT505. Test preparations require the tripping of High Steam Line Flow bistables which make up the High Steam Line Flow coincident with either the Low Steam Line Pressure or Low-Low Tavg Safety Injection logic of the Solid State Protection System. At 1003 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.816415e-4 months <br /> (hrs.), upon trip of the second bistable, a Train "A" Safety Injection and Reactor Trip occurred. All SI, Phase A and Containment Ventilation Isolation components actuated as expected for a single train SI. The unit experienced a Main Feedwater Isolation, a Main Steam Isolation, and auto start of the Auxiliary Feedwater (AFW) system and Emergency Diesel Generators.

Operations entered Emergency Operations Procedure 1 -EOP-TRIP-1, Reactor Trip or Safety Injection, to respond to the trip and SI. Train B of SI was manually actuated. The

Document Control Desk Page 2 JUL 1, 2 2012 LR-N 12-0229 unit then transitioned to 1 -EOP-TRIP-3, Safety Injection Termination, to terminate the SI and realign the plant to transition to Mode 3, Hot Standby conditions.

Accumulated Cycles:

The total number of accumulated actuation cycles to date for Salem Unit I is 22 SI cycles to date.

There are no new commitments in this letter.
