SUBJECT:

PERRY NUCLEAR POWER PLANT, UNIT NO. 1 -REQUEST FOR ADDITIONAL INFORMATION CONCERNING BATTERY SURVEILLANCE TEST FREQUENCIES (TAC NO. MF5298)(L-14-271)

Dear Mr. Harkness:

By application dated November 24, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14328A665), FirstEnergy Nuclear Operating Company (FENOC, the licensee) submitted a license amendment request for the Perry Nuclear Power Plant. The proposed amendment is intended to revise the battery capacity testing surveillance requirements in the technical specification to reflect test requirements when the battery is near end of life. The U.S. Nuclear Regulatory Commission (NRC) staff is reviewing your submittal and has determined that additional information is required to complete the review. The specific information requested is addressed in the enclosure.

During a discussion with Mr. Phil Lashley of your staff on April 1, 2015, it was agreed that FENOC would provide a response within 30 days from the date this letter is electronically distributed The NRC staff considers that timely responses to requests for additional information help ensure sufficient time is available for staff review and contribute toward the NRC's goal of efficient and effective use of staff resources.

E. Harkness Should circumstances result in the need to revise the requested response date, please contact me at (301) 415-2315.

Docket No. 50-440

UNIT NO. 1 DOCKET NO. 50-440 1. In Section 2.0 of the submittal dated November 24, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14328A665), FENOC states: [i]f the DC [direct current] batteries are the only available power source, the maintenance tie circuit breaker may be closed to allow the Unit 1 and Unit 2 [Class 1 E] batteries to be paralleled.

Address whether the impact of paralleling the Units 1 and 2 Class 1 E batteries, such as contribution of additional short circuit current from the Unit 2 batteries, protection coordination, and protective devices ratings among other factors has been considered in the design of Unit 1, 125 volts DC system. Enclosure E. Harkness Should circumstances result in the need to revise the requested response date, please contact me at (301) 415-2315.
