SUPPLEMENTARY INFORMATION:

The NRC has granted the request of Exelon Generation Company, LLC (the licensee) to withdraw its January 31, 2012, application (ADAMS Accession No. ML12033A023), as supplemented by letter dated February 1, 2013 (ADAMS Accession No. ML13035A017), for proposed amendments to Braidwood Station, Units 1 and 2, Facility Operating License No(s). NPF-72 and NPF-77, located in Will County, Illinois and Byron Station, Unit No(s). 1 and 2, Facility Operating License Nos. NPF-37 and NPF-66, located in Ogle County, Illinois.

The proposed amendment would have modified the Updated Final Safety Analysis Report (UFSAR) to describe the use of an Auxiliary Feedwater (AF) cross-tie. Specifically, this change would have added information to the UFSAR describing the design and shared operation of cross-tie piping between the discharges of the Unit 1 and Unit 2 Train A motordriven AF pumps.

The Commission had previously issued a notice of consideration of issuance of amendment published in the Federal Register on May 29, 2012 (77 FR 31660). However, by letter dated June 3, 2015 (ADAMS Accession No. ML15154B363), the licensee withdrew the proposed change.

Dated at Rockville, Maryland, this day of July 9, 2015.

For the Nuclear Regulatory Commission.
