UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 30, 2015 Mr. Eric A. Larson, Site Vice President FirstEnergy Nuclear Operating Company Beaver Valley Power Station Mail Stop A-BV-SEB1 P.O. Box 4, Route 168 Shippingport, PA 15077

SUBJECT:

BEAVER VALLEY POWER STATION, UNIT NOS. 1AND2-CORRECTION TO AMENDMENT NOS. 293 AND 180 REGARDING EXTENSION OF CONTAINMENT LEAKAGE TEST FREQUENCY {TAC NOS. MF3985 AND MF3986)

Dear Mr. Larson:

On April 8, 2015, the U.S. Nuclear Regulatory Commission (NRG) issued Amendment Nos. 293 and 1801 to Renewed Facility Operating License Nos. DPR-66 and NPF-73 for the Beaver Valley Power Station (BVPS), Unit Nos. 1 and 2, in response to your application dated April 16, 2014, as supplemented by letters dated November 4, 2014, and March 23, 2015. The amendments modified the Technical Specification requirements for containment leakage test frequency.

On April 15, 2015, the FirstEnergy Nuclear Operating Company staff notified the NRG staff that one of the safety evaluation pages for BVPS Amendment Nos. 293 and 180 contained typographical errors. Specifically, on page 7 of the safety evaluation, two blocks within Table 4 contain repeated data. The corrected page is enclosed.

Please replace page 7 of the safety evaluation with the enclosed page. The NRG staff regrets any inconvenience this may have caused.

If you have any questions, please contact me at (301) 415-7128.

Sincerely, Taylf;(~oject Plant Licensing Branch 1-2 Manager Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-334 and 50-412

SCFD = Standard Cubic Feet per Day The limit for leakage is 0.6 La for both the as-found minimum pathway leak rate and the as-left maximum pathway leak rate. For BVPS-1, the average as-found minimum pathway leak rate is 19.9 percent of 0.6 La and high of 33.2 percent. Similarly, the average and high as-left maximum pathway leak rate was 38.9 percent and 52.8 percent, respectively.
