(1) Letter from R. M. Krich (Commonwealth Edison Company) to U. S.
NRC, "Request for License Amendment for Power Uprate Operation,"
dated December 27, 2000 (2) Letter from U. S. NRC to 0. D. Kingsley (Exelon Generation Company, LLC), "Dresden Nuclear Power Station, Units 2 and 3 -
Issuance of Amendments for Extended Power Uprate," dated December 21, 2001 (3) Letter from U. S. NRC to O. D. Kingsley (Exelon Generation Company, LLC), "Quad Cities Nuclear Power Station, Units 1 and 2 Issuance of Amendments for Extended Power Uprate," dated December 21,2001 In Reference 1, Commonwealth Edison Company, now Exelon Generation Company (Exelon), LLC, submitted a request for changes to the operating licenses and Technical Specifications for Dresden Nuclear Power Station (DNPS), Units 2 and 3, and Quad Cities Nuclear Power Station (QCNPS), Units 1 and 2, to allow operation at uprated power levels. The NRC approved this request for DNPS and QCNPS in References 2 and 3, respectively.
The NRC Safety Evaluation accompanying the approval of the power uprate amendment requests required that Exelon confirm to the NRC that modifications to the main steam and torus-attached piping systems were completed prior to implementation of the power uprate. These modifications were determined to be necessary based on Exelon's
March 15, 2002 U.S. Nuclear Regulatory Commission Page 2 analysis and included changes to supports, structural attachments, and supporting steel.
For DNPS, Unit 2, these modifications were completed during the refueling outage that ended on November 9, 2001. Implementation of the power uprate occurred on December 21, 2001, for DNPS, Unit 2. For QCNPS, Unit 2, these modifications were completed prior to implementation of the power uprate during the refueling outage that ended on March 5, 2002.
The piping system modifications for DNPS, Unit 3 and QCNPS, Unit 1 will be completed during the next refueling outages on these units, scheduled for fall 2002. Power uprate will be implemented following completion of these modifications. Exelon will notify the NRC upon completion of these modifications and implementation of power uprate at these units.
