Subject:
Salem Nuclear Generating Station, Unit Nos. 1 and 2 - Request to Return Documents for License Amendment Request Data Validation and Reconciliation Date:
Tuesday, February 24, 2026 9:10:00 AM
Dear Mr. Jurek,
By letter dated December31, 2025 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML26002A031), PSEG Nuclear LLC (PSEG) submitted a license amendment request (LAR) for Salem Nuclear Generating Station, Unit Nos. 1 and 2 (Salem). The amendments would allow the licensee to use a data validation and reconciliation (DVR) methodology as the primary means of measurement uncertainty recapture (MUR) at Salem. The letter also requested that Enclosures 3 through 8, 10, and 11 to the letter be withheld from public disclosure because they contain information claimed to be proprietary by GSE Performance Solutions LLC (GSE). Enclosure 12 of the letter provided an affidavit dated November20, 2025, executed by a representative of GSE to support the request to withhold Enclosures 3 through 8, 10, and 11 from public disclosure.
The letter with Enclosures 1, 2, 9, 12, and 13 were made publicly available in ADAMS as they did not include any markings to indicate they should be withheld and PSEG did not request them to be withheld.
Subsequently, the U.S. Nuclear Regulatory Commission (NRC) staff had several nonpublic discussions with PSEG representatives regarding the December31, 2025, submittal.
During these discussions, the NRC staff raised concerns regarding the proprietary claims and the overall scope of the LAR. Finally, on January 15, 2025, the NRC staff held a nonpublic virtual meeting with PSEG representatives to discuss the staffs concerns regarding the overall scope of the LAR in detail. During this meeting, the NRC staff emphasized that recent NRC initiatives to improve the efficiency of its reviews begins with a high-quality application. Although the submittal may have the information needed to support the staffs review of the LAR, the NRC staff noted that the packaging of the information made it difficult for the staff to review in an efficient manner and there appeared to be a lot of information that did not need to be on the docket. The staff noted that the LAR could be improved if a self-contained document that fully addressed the limitations and conditions of the topical report referenced in the LAR was provided. Additionally, the staff noted that it would be more efficient for the staff to audit information not needed on the docket including the calorimetric uncertainty calculation provided in Enclosure 9. The NRC staff recommended that PSEG could either (1) withdraw and resubmit the LAR or (2) withdraw portions of the LAR and submit a supplement.
By letter dated February6, 2026 (ML26037A270), PSEG submitted a supplement to the LAR in response to the concerns raised by the NRC staff. This letter also requested the return of Enclosures 3 through 11 (i.e., Enclosure 9, which was publicly available, and all the enclosures claimed to be proprietary) to the December31, 2025, letter. The NRC staff has reviewed PSEGs request to return these documents in accordance with Title 10 of the Code of Federal Regulations paragraph 2.390(c)(3) and determined that the request can be granted. Therefore, Enclosures 3 through 11 to the December31, 2025, letter will be removed from NRC records in their entirety. No physical copies of these enclosures were provided by PSEG; thus, no physical copies will be returned to PSEG. In addition, as these documents will be removed from NRC records, the NRC staff makes no determination
regarding the proprietary claims in the November20, 2025, GSE affidavit.
Sincerely,
