SUBJECT:

SALEM NUCLEAR GENERATING STATION, UNIT NOS. 1 AND 2, REQUEST FOR ADDITIONAL INFORMATION (RAI) RE: REQUEST FOR CHANGE TO TECHNICAL SPECIFICATIONS ON STEAM GENERATOR LOW-LOW TRIP SETPOINT (TAC NOS. MB6489 AND MB6490)

Dear Mr. Keiser:

By letter dated September 26, 2002, PSEG Nuclear LLC submitted a request for a revision to Technical Specification (TS) Table 2.2-1, Reactor Trip System Instrumentation Trip Setpoints, and Table 3.3-4, Engineered Safety Feature Actuation System Instrumentation Trip Setpoints, for the Steam Generator Low-Low Level Trip setpoint and allowable values at the Salem Nuclear Generating Station, Unit Nos. 1 and 2.

The U.S. Nuclear Regulatory Commission staff is reviewing your request and has determined that additional information is necessary in order to complete its evaluation. We discussed the enclosed RAI with your staff during a telephone call on January 27, 2003. During the call, you agreed to respond to the enclosed RAI within 30 days from the date of this letter. If circumstances result in the need to revise the target date, please contact me at (301) 415-1324.

Sincerely,

/RA/

Robert J. Fretz, Project Manager, Section 2 Project Directorate I Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket Nos. 50-272 and 50-311

The U.S. Nuclear Regulatory Commission (NRC) staff is reviewing your request and has determined that additional information is necessary in order to complete its evaluation.

Question:

Section 4 of Attachment 1 to the September 26, 2002, letter states that the total calculated channel uncertainties for the low-low level channel are +12.233% and 10.339% for Salem Unit Nos. 1 and 2, respectively.

Describe the setpoint methodology, the calculations for the proposed setpoint, and allowable value for the low-low steam generator trip function. If the setpoint methodology is different from the existing methodology, the NRC will review it. The setpoint calculation for each unit should include the uncertainty values and the bases for all measurement instrument components, rack calibration accuracy, and the bias (pressure drop and equivalent % of narrow range span) assigned to account for the effect of the mid-deck plate pressure differential induced by the primary separator downcomer steam flow.
