DPR-33, DPR-52, and DPR-68 NRC Docket Nos. 50-259, 50-260, and 50-296
Subject:
Emergency Response Data System Changes The purpose of this letter is to provide changes to the Emergency Response Data System (EROS), as required by Title 10 of the Code of Federal Regulations (1 O CFR) 50, Appendix E, Section Vl.3, "Maintaining Emergency Response Data System" for Browns Ferry Nuclear Plant (BFN), Units 1, 2, and 3. This revision to the EROS changed the upper range limit on EROS data point SPDS0024. The changes to the EROS Data Point Library are summarized in the Enclosure.
This change is being provided in accordance with 10 CFR 50, Appendix E, Section Vl.3.a, which requires a notification within 30 days after the changes are made for any software or hardware changes to any transmitted data points identified in the Data Point Library. This change went into effect on June 2, 2017.
There are no new regulatory commitments in this letter. Please direct questions concerning this issue to Jamie L. Paul at (256) 729-2636.
