SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE BYRON STATION, UNITS 1 AND 2, AND BRAIDWOOD STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION, SET 34 (TAC NOS. MF1879, MF1880, MF1881, AND MF1882)
Dear Mr. Gallagher:
By letter dated May 29, 2013, Exelon Generation Company, LLC, submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54, to renew the operating licenses NPF-37, NPF-66, NPF-72, and NPF-77 for Byron Station, Units 1 and 2, and Braidwood Station, Units 1 and 2, respectively, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review.
These requests for additional information were discussed with John Hufnagel, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-4115 or by e-mail at Lindsay.Robinson@nrc.gov.
Sincerely,
/RA/
Lindsay R. Robinson, Project Manager Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket Nos. 50-454, 50-455, 50-456, and 50-457

BYRON STATION, UNITS 1 AND 2, AND BRAIDWOOD STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION, SET 34 (TAC NOS. MF1879, MF1880, MF1881, MF1882)
RAI 2.3.3.12-4 Applicability:
Byron Station (Byron) and Braidwood Station (Braidwood), Units 1 and 2
Background:
For Byron Station, Units 1 and 2, and Braidwood Station, Units 1 and 2, the staff reviewed the combined license renewal application (LRA), drawings, and several other applicable documents.
LRA Section 2.3.3.12 discusses requirements for the fire water supply system but does not mention suction screens for the fire pump suction water supply. The intake traveling screens were not included in the license renewal boundaries; however, they appear to have fire protection intended functions required for compliance with Title 10 of the Code of Federal Regulations (CFR) 50.48, Fire protection, as stated in 10 CFR 54.4. Intake traveling screens are located upstream of the fire pump suctions to remove any major debris from the fresh or raw water. Intake traveling screens are necessary to remove debris from and prevent clogging of the fire protection water supply system and have a passive intended function of filter.
Issue:
Tables 2.3.3-12 and 3.3.2-12 of the LRA do not include the intake traveling screens.
Request:
The staff requests that the applicant verify whether the intake traveling screens are in the scope of license renewal in accordance with 10 CFR 54.4(a) and whether they are subject to an aging management review (AMR) in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and are not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
