- 5. Prior LOCA Assessment The referenced letter provided the annual 50.46 report for QCNPS Units 1 and 2.
This letter reported GE LOCA errors related to SAFER level/volume table and Steam Separator pressure drop and mid-cycle reload of GE14 fuel for Unit 1 Page 1 of 4
Attachment 5 Quad Cities Nuclear Power Station Units 1 and 2 10 CFR 50.46 Report Assessment Notes (Cycle 18A). For Unit 2, this letter reported the same GE LOCA errors and second reload of GE14 fuel in Cycle 18 core. The PCT impact for these errors and reloads of GE14 fuel was determined to be 0°F.

- 6. Prior LOCA Assessment The referenced letter provided the annual 50.46 report for QCNPS Units 1 and 2.
This letter reported GE LOCA error due to new heat source for QCNPS Units 1 &
2 and QCNPS Unit 1 Cycle 19 with a new reload of GE14 fuel .
[Reference : Letter from Patrick R. Simpson (Exelon) to U .S. NRC, Transmittal of 10 CFR 50.46, "Acceptance criteria for emergency core cooling systems for light water nuclear power reactors," Annual Report for Quad Cities Nuclear Power Station, Units 1 and 2, RS-05-056, dated May 5, 2005.]
- 7. Prior LOCA Assessment The referenced letter provided the annual 50.46 report for QCNPS Units 1 and 2 .
This letter reported LOCA evaluations for installation of new steam dryers during mid-cycle outages for Q1 C19 and Q2C18, respectively . Also, the letter reported Q2C19 startup in April 2006 with the first reload of Westinghouse Optima2 fuel and implementation of the Westinghouse LOCA analysis . Additionally, LOCA evaluations by both GE and Westinghouse were reported for the QCNPS Unit 2 modification to the inlet configuration of the 6" inlet standpipe of eight main steam safety valves and four Electromatic relief valves, which replaced the previously installed inlet pipe and flange with a 6" Tee, flange and an Acoustic Side Branch (ASB). The PCT impact due to the plant modifications was determined to be 0°F.

- 8. Prior LOCA Assessment The referenced letter provided the annual 50.46 report for QCNPS Units 1 and 2.
This letter reported GE LOCA evaluation for installation of a modification to the inlet configuration of the 6" inlet standpipe of eight main steam safety valves and four Electromatic relief valves for QCNPS Unit 1 . Also, this letter reported evaluation of a change in the GE small break analysis assumption for axial power shape and Westinghouse LOCA analysis Hgap correlation input error. The PCT impact due to these changes was determined to be 0° F.

9 . Prior LOCA Assessment Westinghouse performed a new plant-specific LOCA Analysis for QCNPS. This new analysis applies to operation of the Westinghouse Optima2 fuel in the QCNPS Unit 1 and 2 reactors . This analysis applies specific inputs and assumptions in the LOCA calculation approved in the licensed Westinghouse methodology. Also, a second reload of SVEA-96 Optima2 fuel was implemented with the QCNPS Unit 2 Cycle 20 core . The limiting PCT for Optima2 as analyzed under the Westinghouse LOCA method is 2150 °F whereas the limiting PCT for GE14 as analyzed under GE LOCA method is 2110 °F .

10 . Current LOCA Assessment Westinghouse revised the QCNPS Units 1 & 2 LOCH report to address a non-conservative low-pressure core spray (LPCS) flow error identified for Dresden Nuclear Power Station (DNPS) Unit 2 in the DNPS LOCA analysis . The changes in Revision 4 of the DNPS report are required to be added to the QCNPS report to clarify the LPCS flow and leakage model for the QCNPS LOCA analysis . The QCNPS LOCA analysis is not affected by the non-conservative DNPS LPCS flow error.
