CALLAWAY PLANT, UNIT 1-ACCEPTANCE OF APPLICATION DATED MAY 4, 2009 (ME1325)

Mr. Adam C. Heflin Senior Vice President and Chief Nuclear Officer Union Electric Company P.O. Box 620 Fulton, MO 65251

SUBJECT:

CALLAWAY PLANT, UNIT 1 - ACCEPTANCE OF REQUESTED LICENSING ACTION RE: REVISION TO TECHNICAL SPECIFICATIONS 3.7.3 AND 3.3.2 (TAC NO. ME1325),

Dear Mr. Heflin:

By letter dated May 4, 2009 (Agencywide Document Access and Management System (ADAMS) Accession No. ML091280111), Union Electric Company (the licensee) requested the U.S. Nuclear Regulatory Commission (NRC) staff for approval of a revision to Callaway Plant, Unit 1 Technical Specifications (TS).

The proposed amendment would revise (TS) 3.7.3, "Main Feedwater Regulating Vales (MFIVs) and Main Feedwater Regulating Valve Bypass Valves(MFRVBVs)," so that the Limiting Condition for Operation (LCO) and Applicability more accurately reflect the conditions for when the LCO should be applicable and more effectively provide appropriate exceptions to the Applicability for certain valve configurations. Additionally, changes are proposed for the exception footnotes in Table 3.3.2.1 of TS3.3.2, "ESFAS Instrumentation," in order to improve the application of existing notes and/or incorporate more appropriate notes as applicable.

The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staff=s acceptance review of this request. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.

The NRC staff has reviewed the application and concluded that it does provide technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed revision to TS 3.7.3 and TS 3.3.2, in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised of it by separate correspondence.

If you have any questions, please contact me at (301) 415-1476 or email Mohan.Thadani@nrc.gov.
