Subject:

Supplement to License Amendment Request to Revise Technical Specification Surveillance Requirements for Direct Current Batteries In Reference 2, DTE Electric Company (DTE) submitted a License Amendment Request (LAR) to revise Technical Specifications (TS) Surveillance Requirements (SR) associated with TS 3.8.4, "DC Sources - Operating" and TS 3.8.6, "Battery Cell Parameters." During a telephone conversation with NRC staff on June 2, 2014, it was determined that a clarification was needed to align the TS markup and revision for SR 3.8.4.2 with the changes proposed in Enclosure 1 of Reference 2. of this letter provides a revised TS markup page to replace Reference 2, , TS page 3.8-17. Enclosure 2 of this letter provides a revised clean TS page to replace Reference 2, Enclosure 3, TS page 3.8-17.

Should you have any questions or require additional information, please contact Mr.

Zackary W. Rad of my staff at (734) 586-5076.

Sincerely,
