RS-05-176 December 15, 2005 U. S. Nuclear Regulatory Comm ATTN : Document Control Desk Washington, DC 20555-0001 sion Quad Cities Nuclear Power Station, Unit 2 Renewed Facility Operating License No. DPR-30 NRC Docket No. 50-265
Subject:
Request for Technical Specifications Change for Minimum Critical Power Ratio Safety Limit In accordance with 10 CFR 50.90, "Application for amendment of license or construction permit," Exelon Generation Company, LLC (EGC) requests an amendment to Renewed Facility Operating License No. DPR-30 for Quad Cities Nuclear Power Station, Unit 2. The proposed change revises the values of the safety limit minimum critical power ratio (SLMCPR) in Technical Specification (TS) Section 2.1.1, "Reactor Core SLs." Specifically, the proposed change would require that for Unit 2, the minimum critical power ratio (MCPR) for Global Nuclear Fuel (GNF) fuel shall be _> ~ 1.09 for two recirculation loop operation, or 2: 1.10 for single recirculation loop operation. Additionally, the proposed change would require that MCPR for Westinghouse fuel shall be ?: 1.11 for two recirculation loop operation, or ?~ 1.13 for single recirculation loop operation.
This request is subdivided as follows.
9 Attachment 1 provides an evaluation supporting the proposed change.
10C 0 Attachment 2 contains the marked-up TS page, with the proposed change indicated.
chment 3 provides the retyped TS page, with the proposed change incorporated.
5 provides a marked-up copy of the affected TS Bases pages. The TS Bases pages are provided for information only, and do not require NRC approval. provides a description of the SLMCPR evaluation for QC PS Unit 2 Cycle 19, as well as a summary of the Westinghouse establishment of a critical power rati correlation for G NF GE14 fuel.
December 15, 2005 U. S. Nuclear Regulatory Commission Page 2 The proposed change has been reviewed by the QCNPS Plant Operations Review Committee and approved by the Nuclear Safety Review Board in accordance with the requirements of the EGC Quality Assurance Program.
EGC requests approval of the proposed change by March 15, 2006, to support startup following the next refueling outage for Unit 2 (i.e., Q2R18), which is scheduled to start in March 2006. Once approved, the amendment shall be implemented prior to startup from Q2R1 8. This implementation period will provide adequate time for the affected station documents to be revised using the appropriate change control mechanisms.
In accordance with 10 CFR 50.91 (b), EGC is notifying the State of Illinois of this application for changes to the TS by transmitting a copy of this letter and its attachments to the designated State Official. contains information proprietary to Westinghouse Electric Company LLC; it is supported by an affidavit signed by Westinghouse, the owner of the information.
