LCR S06-03 SUPPLEMENT REQUEST FOR CHANGE TO TECHNICAL SPECIFICATIONS ACCIDENT MONITORING INSTRUMENTATION AND SOURCE CHECK DEFINITION
References:
(1) Letter from PSEG to NRC: "LCR S06-03, Request for Change to Technical Specifications, Accident Monitoring Instrumentation and Source Check Definition, Salem Nuclear Generating Station, Units 1 and 2, Facility Operating Licenses DPR-70 and DPR-75, Docket Nos. 50-272 and 50-311", dated May 1, 2006 (2) Letter from PSEG to NRC: "Response to RAls on LCR S06-03, Request for Change to Technical Specifications, Accident Monitoring Instrumentation and Source Check Definition, Salem Nuclear Generating Station, Units 1 and 2, Facility Operating Licenses DPR-70 and DPR-75, Docket Nos. 50-272 and 50-311", dated October 9, 2006 In accordance with the requirements of 10 CFR 50.90, PSEG Nuclear LLC (PSEG) previously submitted License Change Request (LCR) S06-03, dated May 1, 2006, to amend the Technical Specifications (TS) for Salem Generating Station Unit 1 and Unit 2 (Reference 1). LCR S06-03 contained two proposed changes: (1) Relocation of the Main Steamline Discharge (Safety Valves and Atmospheric Dumps) Radiation Monitors (R46) from the radiation monitoring instrumentation technical specification (3.3.3.1) to the accident monitoring technical specification (3.3.3.7), and (2) Modification of TS Definition 1.31, SOURCE CHECKS, to allow for different methods to comply with the SOURCE CHECK requirement.
PSEG received a Request for Additional Information (RAI) from the NRC on LCR S06-
- 03. The response to the RAI was provided via Reference 2 dated October 9, 2006.

FEB 2 1 2007 Document Control Desk LR-N07-0036 On February 8, 2007, PSEG and the NRC Staff discussed (via telecon) the SOURCE CHECK definition change requested in LCR S06-03. PSEG agreed to revise the definition to include specific options for complying with the source check requirement.
The revised wording is provided below:
"SOURCE CHECK shall be the qualitative assessment of channel response when the channel sensor is exposed to either (a) an external source of increased radioactivity, (b) an internal source of radioactivity (keep-alive source), or (c) an equivalent electronic source check."
The revised TS pages are provided in Attachment 1.
The revised definition is an updated clarification, and meets the intent of the original definition and ensures the proper functioning of detectors, based on the detector design.
If a detector is designed with source check capability via exposure to an external source (i.e., by an actual source attached to a mechanical device as part of the detector design), then this method would be employed. Improved technology detectors will be "qualitatively assessed" in a manner that is a significant improvement over the old methodology, and that is appropriate to their design. The proposed revised definition will allow for equivalent qualitative assessment methods, recognizing the technology of improved designs. As examples, the R46 detectors use a keep alive source, and the R44 detectors use an equivalent electronic source check (refer to Salem Amendments 272 and 253, NRC letter dated May 5, 2006)1.
If you have any questions or require additional information, please do not hesitate to contact Mr. Jamie Mallon at (610) 765-5507.
I declare under penalty of perjury that the foregoing is true and correct.

/e Site Vice President Salem Generating Station Attachments 1 Note that the SOURCE CHECK requirement is only applicable for detectors in TS 3.3.3.1. The R44 detectors were relocated to TS 3.3.3.7, and the R46 detectors are proposed for relocation to TS 3.3.3.7.
