The U.S. Nuclear Regulatory Commission (NRC) has granted the request of Union Electric Co., (the licensee) to withdraw its application dated June 30, 2011 (ADAMS Accession No. ML111820367), as supplemented by letter dated September 10, 2012 (ADAMS Accession No. ML1225A040), for proposed amendment to Facility Operating License No. NPF-30 for the Callaway Plant, Unit 1, located in Callaway County, Missouri.

The proposed amendment would have revised Technical Specification (TS) 3.6.6, “Containment Spray and Cooling Systems.” Specifically, the amendment would have revised Surveillance Requirement (SR) for verifying the minimum required containment cooling train cooling water flow rate. Rather than require verifying each containment cooling train has a cooling water flow rate greater than or equal to 2200 gallons per minute, TS SR would have been revised to require verification that the flow rate is capable of being “within limits” for achieving the heat removal rate assumed in the Callaway Plant safety analyses.

The Commission had previously issued a Notice of Consideration of Issuance of Amendment published in the Federal Register on November 1, 2011 (76 FR 67491). However, by letter dated October 26, 2012 (ADAMS Accession No. ML12305A202), the licensee withdrew the proposed change.

For further details with respect to this action, see the application for amendment dated June 30, 2011, the supplement dated September 10, 2012, and the license's letter dated October 26, 2012, which withdrew the application for license amendment.

Dated at Rockville, Maryland, this 5th day of November 2012.

For the Nuclear Regulatory Commission.

Carl F. Lyon,

Project Manager, Plant Licensing Branch IV, Division of Operating Reactor Licensing, Office of Nuclear Reactor Regulation.
