RAI REGARDING LICENSE AMENDMENT RELATED TO REQUEST TO REVISE BATTERY CONNECTION RESISTANCE ACCEPTANCE CRITERIA IN TECHNICAL SPECIFICATIONS Mr. Hentz The following Request for Information (RAI) from the Nuclear Regulatory Commission (NRC) staff pertains to the proposed 125 volt direct current battery connection resistance acceptance values in the TS for Catawba 1 and 2 and McGuire 1 and 2 as described in the license amendment request (LAR) sent by letter dated December 14, 2009 (Agencywide Documents Access and Management System (ADAMS), Accession No. ML093500597), as supplemented by letter dated September 8, 2010 (ADAMS Accession No. ML102560066), submitted by Duke Energy Carolinas, LLC (the licensee):
Attachment 1 of both Enclosure 1 (for McGuire 1 and 2) and Enclosure 2 (for Catawba 1 and 2) of the licensees letter dated September 8, 2010, responded to an NRC staff RAI pertaining to the battery resistance TS LAR. This letter included two recommendations from the battery manufacturer for each station. One of the battery manufacturers recommendations was to add one 1/4-inch intercell connector on each side of the battery post (NCN-27 for McGuire 1 and 2 or NCN-21 for Catawba 1 and 2) for a total of 2 x 1/4-inch connectors on each side of each battery post.
a) Describe how the licensee addressed the battery manufacturers recommendation; and b) Explain how the maximum allowable voltage drop of 0.050V relates to this recommendation.
Please contact me if you are not able to respond to this RAI within 30 days of receipt.
Sincerely Jon Thompson, Project Manager Plant Licensing Branch II-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation E-mail Properties Mail Envelope Properties ()
