UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001
..Jure 16, 2Dl1 Mr. Mark B. Bezilla Site Vice President FirstEnergy Nuclear Operating Company Mail Stop A-PY-A290 P.O. Box 97, 10 Center Road Perry,OH 44081-0097 SUB~IECT:
PERRY NUCLEAR POWER PLANT, UNIT NO.1 - CORRECTION LETTER RE: LICENSE AMENDMENT NO. 157
Dear Mr. Bezilla:
On May 19, 2011 the U.S. Nuclear Regulatory Commission (NRC) issued Amendment No. 157 to Facility Operating License (FOL) No. NPF-58 for the Perry Nuclear Power Plant (PNPP), Unit No.1 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML11105A0380). This license amendment modified the requirements for testing control rod scram times following fuel movement within the reactor pressure vessel by incorporating the NRC approved Technical Specification Task Force (TSTF) change traveler TSTF-222-A, Revision 1.
Also, on May 19, 2011, the NRC issued Amendment No. 156 to FOL No. NPF-58 for PNPP (ADAMS Accession No. ML1110502670). This license amendment modifies the required testing frequency of Surveillance Requirement 3.1.4.2 from "120 days cumulative operation in MODE 1" to "200 days cumulative operation in MODE 1," by incorporating NRC-approved T TSTF-460, Revision O.
Amendment No. 156 made changes on the same Technical Specification (TS) page (TS 3.1-13) as Amendment No. 157. Since both amendments were issued so close to each other, Amendment No. 157 TS changes did not reflect the Amendment No. 156 changes. Therefore the TS pages (3.1-12 and 3.1-13) for Amendment No. 157 are being reissued by this letter, with the Amendment No. 156 changes incorporated.
