CORRECTION TO AMENDMENT NOS. 308 AND 312 REGARDING SURVEILLANCE REQUIREMENTS FOR HIGH PRESSURE COOLANT INJECTION SYSTEM AND REACTOR CORE ISOLATION COOLING SYSTEM (CAC NOS. MF6774 AND MF6775)

Dear Mr. Hanson:

By letter dated July 5, 2016 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16159A148), the U.S. Nuclear Regulatory Commission (NRC) staff issued Amendments Nos. 308 and 312 to Renewed Facility Operating License Nos. DPR-44 and DPR-56 for the Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3. The amendments: (1) revised the allowable test pressure band in the technical specification (TS}

surveillance requirements (SRs) for the pump flow testing of the high pressure coolant injection system and the reactor core isolation system; (2) revised the surveillance frequency requirements for verifying the sodium pentaborate enrichment of the standby liquid control system; and (3) deleted SRs associated with verifying the manual transfer capability of the normal and alternate power supplies for certain motor-operated valves associated with the suppression pool spray and drywell spray sub-systems of the residual heat removal system.

In preparation for implementation of the above referenced amendments, the Exelon Generation Company, LLC (Exelon) staff informed the NRC staff that several of the TS pages revised by Amendment Nos. 308 and 312, did not reflect changes made in PBAPS, Units 2 and 3, Amendment Nos. 297 and 300, issued by the NRC staff on June 30, 2015 (ADAMS Accession No. ML15154A614). The error resulted, in part, due to the wrong camera ready pages being provided by Exelon in support of the issuance of Amendment Nos. 308 and 312. The corrected pages are enclosed.

If you have any questions, I can be reached at (301) 415-1420 or by e-mail at Rick.Ennis@nrc.gov.
