Letter from Mr. Jeffrey L. Hansen (Exelon Generation Company, LLC) to U. S. NRC, "Additional lnformation Supporting the Request for a License Amendment to Modify Clinton Power Station Facility Operating License in Support of the Use of lsotope Test Assemblies," dated November 17, 2009 In Reference 1, Exelon Generation Company, LLC (EGC) requested an amendment to the facility operating license for Clinton Power Station (CPS), Unit 1. Specifically, the proposed change would modify CPS License Condition 2.B.(6) and create new License Conditions 1 .J and 2.8.(7) as part of a pilot program to irradiate Cobalt (Co)-59 targets to December 14,2009 U. S. Nuclear Regulatory Commission Page 2 produce Co-60. | |||
In addition to the proposed license condition changes, EGC also requests an amendment to Appendix A, Technical Specifications (TS), of the CPS Facility Operating License. This proposed change would modify TS 4.2.1, "Fuel Assemblies," to describe the Isotope Test Assemblies (ITAs) being used. In Reference 2, the NRC requested that EGC provide additional information in support of their review of Reference | |||
: 1. The NRC request for additional information and the specific EGC responses were provided in References 3 and 4. In response to RAls 4 and 6, EGC agreed to provide the CPS Cycle 13 Supplemental Reload Licensing Report to the NRC. The attachment to this letter contains the final version of this report. EGC has reviewed the information supporting a finding of no significant hazards consideration that was previously provided to the NRC in Reference | |||

: 15. Stability Analysis Results 15.1 Stability Option 111 Solution Clinton has implemented BWROG Long Term Stability Solution Option 111 using the Oscillation Power Range Monitor (OPRM) as described in Reference 1 in Section 15.4. The plant specific Hot Channel Oscillation Magnitude (HCOM) (Reference 2 in Section 15.4) and other cycle specific stability parameters are used in the Cycle 13 Option I11 stability evaluation. Backup Stability Protection (BSP) regions are used by the plant in the event that the Option I11 OPRM system is declared inoperable. The following Option 111 OPRM stability setpoint determination described in Section 15.2 and the implementation of the associated BSP Regions described in Section 15.3 provide the stability licensing bases for Clinton Cycle 13. | |||
15.2 Detect and Suppress Evaluation A reload Option 111 evaluation has been performed in accordance with the licensing methodology described in Reference 3 in Section 15.4. The stability based OLMCPR is determined for two conditions as a function of OPRM amplitude setpoint. The two conditions evaluated are: (1) a postulated oscillation at 45% rated core flow quasi steady-state operation (SS), and (2) a postulated oscillation following a two recirculation pump trip (2PT) from the limiting rated power operation state point. The OPRM-setpoint-dependent OLMCPR(SS) and OLMCPR(2PT) values are calculated for Cycle 13 in accordance with the BWROG regional mode DIVOM guidelines described in Reference 4 in Section 15.4. The Cycle 13 Option I11 evaluation provides adequate protection against violation of the SLMCPR for the two postulated reactor instability events as long as the plant OLMCPR is equal to or greater than OLMCPR(SS) and OLMCPR(2PT) for the selected OPRM setpoint in Table 15-2. The relationship between the OPRM Successive Confirmation Count Setpoint and the OPRM Amplitude Setpoint is provided in Reference 3 in Section 15.4 and Table 15-1. For intermediate OPRM Amplitude Setpoints, the corresponding OPRM Successive Confirmation Count Setpoints have been obtained by using linear interpolation. The OPRM setpoints for TLO are conservative relative to SLO and are, therefore, bounding. | |||

Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix B Thermal-Mechanical Compliance A thermal-mechanical compliance check is performed for all analyzed transients to assure that the fuel will operate without violating the thermal-mechanical design limits. These limits are designed such that reactor operation within these limits provides assurance that the fuel will not exceed any thermal- mechanical design or licensing limits during all modes of operation. The fuel thermal-mechanical limits are met for the current cycle. Page 32 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix C Decrease in Core Coolant Temperature Event The Loss-of-Feedwater Heating event was analyzed at 100% rated power using the BWR Simulator Code. The use of this code is consistent with the approved methodology. | |||
The transient plots, neutron flux and heat flux values normally reported in Section 9 are not an output of the BWR Simulator Code; therefore, those items are not included in this document. The OLMCPR result is shown in Section 1 1. Page 33 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix D Off-Rated Limits Off-Rated Power Dependent Limits The ARTS MCPRp and LHGRFACp thermal limits in this appendix have been validated this cycle for operation with Equipment-In-Service, PROOS, 1 Turbine Bypass Valve OOS (1 TBVOOS) and Turbine Bypass System OOS (TBSOOS). These limits support FFWTR of 120°F, 24 month cycle operation (Reference D-7) and the established EOOS options in References D-1 and D-2. The Effect of the PLU Power Level on Off-Rated Limits The results of Reference D-3 show that the generic Kp and LHGRFACp are validated, i.e., the PLU LRNBP is bounded by the Equipment-In-Service limits for the 0.3 14 second TT delay. The Effect of Feedwater Riser Flow Asymmetry on Thermal Limits The results of Reference D-4 show that the asymmetric effect in core enthalpy distribution on thermal limits due to the difference in flow to each of the 4 feedwater risers is insignificant. Reference D-4 concluded that for a feedwater riser flow deviation of 2.5% or less, the impact on MCPR thermal margins is less than 1% and no adjustment to the OLMCPRs is required. However, it was determined that when operating with FWHOOS or FFWTR up to 50°F, an adjustment of 1% to the LHGR limits is required. | |||
The Effect of Rated Dome Pressure at Reactor Powers of 70% to 100% on Thermal Limits To reduce excessive recirculation pump shaft seal wear associated with pressure reductions, Reference D-5 supports operation between 70% and 100% rated thermal power with rated dome pressure. There is no impact to the licensing and analysis bases based on this operation. However, changes to the pressure regulator to maintain rated dome pressure as power decreases should be gradual in order to avoid a plant scram due to pressure and power perturbations. Shroud Repair Impact on Thermal Limits The analyses addressed in this report do not invalidate the statements made in Reference D-6 with respect to the shroud repair impact on Transient and Accident analyses for Clinton Power Station. Potential Violation of Low Pressure Technical Specification Limit Evaluations of Pressure Regulator Failure Maximum Demand (Open) transients have shown that the typical PRFO (for plants known to be vulnerable) results in the dome pressure dropping below 785 psig for a short duration (approximately 5 seconds). The recommendations associated with lOCFR Part 21 Communication SC05-03 (Reference D-8) have not changed. Page 34 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 MCPRp Limits for: | |||

The CPS specific Option B scram times result in approximately 0.1 improvement in the OLMCPR for fast pressurization events such as the FWCF, LRNBP and TTNBP. The results of the pressurization events (FWCF, LRNBP and TTNBP) in Sections 6 and 9 with the corresponding figures are based on Option B scram times. The Pressure Regulator Failure event is based on Option A scram times. Reference for Appendix E: E-1 Option B Scram Times for Clinton Power Station, GE-NE-0000-0000-7456-OlP, February 2002. Page 41 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix F Final Feedwater Temperature Reduction (FFWTR) | |||
The reload transient analyses were performed using a Final Feedwater Temperature Reduction (FFWTR) of 120.0°F. The 120.0°F FFWTR reported in Section 8 is not consistent with Reference F-1 and is not currently licensed for Clinton Power Station. The reload transient analyses do not by themselves allow plant operation with 120.0°F FFWTR but are bounding for the FFWTR of 50.0" F in Reference F- 1. Reference for Appendix F: F-1 Safety Analysis Report for Clinton Power Station Extended Power Uprate, NEDC-32989P, June 200 1. Page 42 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix G GE141 Fuel Introduction Reference G-1 provided the results of the cycle-independent evaluations supporting the introduction of GE141 fuel in Clinton Power Station. | |||
These GE141 bundles, also referred to as GE141 Isotope Test Assemblies (ITAs), were designed for mechanical, nuclear and thermal-hydraulic compatibility with the GE14C fuel designs. The Cycle 13 core was designed such that the ITAs would be placed in non-limiting locations with respect to thermal limit margins and shutdown margins. Section 11 of this report presents the GE14C cycle-dependent MCPR limits; an adder of 0.07 should be applied to these results for the GE141 ITAs. References for Appendix G: G-1. Safety Analysis Report to Support Introduction ofGEI4i Isotope Test Assemblies (ITAs) in Clinton Power Station, NEDC-33505P Revision 0, GE Hitachi Nuclear Energy (Proprietary), June 2009; and Errata and Addenda Number I, December 4,2009. Page 43 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix H Calculated BSP Region End Points The BSP region end points reported in Section 15 represent the proposed BSP region. The proposed BSP region is conservative and bounds the calculated BSP region end points. To support the initial introduction of GE14I Isotope Test Assemblies (ITAs), this appendix provides the calculated BSP region end points and decay ratios.

Stability Analysis Results 15.1 Stability Option 111 Solution Clinton has implemented BWROG Long Term Stability Solution Option 111 using the Oscillation Power Range Monitor (OPRM) as described in Reference 1 in Section 15.4. The plant specific Hot Channel Oscillation Magnitude (HCOM) (Reference 2 in Section 15.4) and other cycle specific stability parameters are used in the Cycle 13 Option I11 stability evaluation. Backup Stability Protection (BSP) regions are used by the plant in the event that the Option I11 OPRM system is declared inoperable. The following Option 111 OPRM stability setpoint determination described in Section 15.2 and the implementation of the associated BSP Regions described in Section 15.3 provide the stability licensing bases for Clinton Cycle 13.
15.2 Detect and Suppress Evaluation A reload Option 111 evaluation has been performed in accordance with the licensing methodology described in Reference 3 in Section 15.4. The stability based OLMCPR is determined for two conditions as a function of OPRM amplitude setpoint. The two conditions evaluated are: (1) a postulated oscillation at 45% rated core flow quasi steady-state operation (SS), and (2) a postulated oscillation following a two recirculation pump trip (2PT) from the limiting rated power operation state point. The OPRM-setpoint-dependent OLMCPR(SS) and OLMCPR(2PT) values are calculated for Cycle 13 in accordance with the BWROG regional mode DIVOM guidelines described in Reference 4 in Section 15.4. The Cycle 13 Option I11 evaluation provides adequate protection against violation of the SLMCPR for the two postulated reactor instability events as long as the plant OLMCPR is equal to or greater than OLMCPR(SS) and OLMCPR(2PT) for the selected OPRM setpoint in Table 15-2. The relationship between the OPRM Successive Confirmation Count Setpoint and the OPRM Amplitude Setpoint is provided in Reference 3 in Section 15.4 and Table 15-1. For intermediate OPRM Amplitude Setpoints, the corresponding OPRM Successive Confirmation Count Setpoints have been obtained by using linear interpolation. The OPRM setpoints for TLO are conservative relative to SLO and are, therefore, bounding.

The endpoints of the regions are defined in Tables 15-3 and 15-4. The region boundaries, shown in Figures 8 and 9, are defined using the Modified Shape Function (MSF).

Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix B Thermal-Mechanical Compliance A thermal-mechanical compliance check is performed for all analyzed transients to assure that the fuel will operate without violating the thermal-mechanical design limits. These limits are designed such that reactor operation within these limits provides assurance that the fuel will not exceed any thermal- mechanical design or licensing limits during all modes of operation. The fuel thermal-mechanical limits are met for the current cycle. Page 32 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix C Decrease in Core Coolant Temperature Event The Loss-of-Feedwater Heating event was analyzed at 100% rated power using the BWR Simulator Code. The use of this code is consistent with the approved methodology.
The transient plots, neutron flux and heat flux values normally reported in Section 9 are not an output of the BWR Simulator Code; therefore, those items are not included in this document. The OLMCPR result is shown in Section 1 1. Page 33 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix D Off-Rated Limits Off-Rated Power Dependent Limits The ARTS MCPRp and LHGRFACp thermal limits in this appendix have been validated this cycle for operation with Equipment-In-Service, PROOS, 1 Turbine Bypass Valve OOS (1 TBVOOS) and Turbine Bypass System OOS (TBSOOS). These limits support FFWTR of 120°F, 24 month cycle operation (Reference D-7) and the established EOOS options in References D-1 and D-2. The Effect of the PLU Power Level on Off-Rated Limits The results of Reference D-3 show that the generic Kp and LHGRFACp are validated, i.e., the PLU LRNBP is bounded by the Equipment-In-Service limits for the 0.3 14 second TT delay. The Effect of Feedwater Riser Flow Asymmetry on Thermal Limits The results of Reference D-4 show that the asymmetric effect in core enthalpy distribution on thermal limits due to the difference in flow to each of the 4 feedwater risers is insignificant. Reference D-4 concluded that for a feedwater riser flow deviation of 2.5% or less, the impact on MCPR thermal margins is less than 1% and no adjustment to the OLMCPRs is required. However, it was determined that when operating with FWHOOS or FFWTR up to 50°F, an adjustment of 1% to the LHGR limits is required.
The Effect of Rated Dome Pressure at Reactor Powers of 70% to 100% on Thermal Limits To reduce excessive recirculation pump shaft seal wear associated with pressure reductions, Reference D-5 supports operation between 70% and 100% rated thermal power with rated dome pressure. There is no impact to the licensing and analysis bases based on this operation. However, changes to the pressure regulator to maintain rated dome pressure as power decreases should be gradual in order to avoid a plant scram due to pressure and power perturbations. Shroud Repair Impact on Thermal Limits The analyses addressed in this report do not invalidate the statements made in Reference D-6 with respect to the shroud repair impact on Transient and Accident analyses for Clinton Power Station. Potential Violation of Low Pressure Technical Specification Limit Evaluations of Pressure Regulator Failure Maximum Demand (Open) transients have shown that the typical PRFO (for plants known to be vulnerable) results in the dome pressure dropping below 785 psig for a short duration (approximately 5 seconds). The recommendations associated with lOCFR Part 21 Communication SC05-03 (Reference D-8) have not changed. Page 34 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 MCPRp Limits for:

The CPS specific Option B scram times result in approximately 0.1 improvement in the OLMCPR for fast pressurization events such as the FWCF, LRNBP and TTNBP. The results of the pressurization events (FWCF, LRNBP and TTNBP) in Sections 6 and 9 with the corresponding figures are based on Option B scram times. The Pressure Regulator Failure event is based on Option A scram times. Reference for Appendix E: E-1 Option B Scram Times for Clinton Power Station, GE-NE-0000-0000-7456-OlP, February 2002.

The reload transient analyses were performed using a Final Feedwater Temperature Reduction (FFWTR) of 120.0°F. The 120.0°F FFWTR reported in Section 8 is not consistent with Reference F-1 and is not currently licensed for Clinton Power Station. The reload transient analyses do not by themselves allow plant operation with 120.0°F FFWTR but are bounding for the FFWTR of 50.0" F in Reference F- 1.

These GE141 bundles, also referred to as GE141 Isotope Test Assemblies (ITAs), were designed for mechanical, nuclear and thermal-hydraulic compatibility with the GE14C fuel designs. The Cycle 13 core was designed such that the ITAs would be placed in non-limiting locations with respect to thermal limit margins and shutdown margins. Section 11 of this report presents the GE14C cycle-dependent MCPR limits; an adder of 0.07 should be applied to these results for the GE141 ITAs. References for Appendix G: G-1.

Page 43 Clinton 0000-0099-4244-SRLR Reload 12 Revision 0 Appendix H Calculated BSP Region End Points The BSP region end points reported in Section 15 represent the proposed BSP region. The proposed BSP region is conservative and bounds the calculated BSP region end points. To support the initial introduction of GE14I Isotope Test Assemblies (ITAs), this appendix provides the calculated BSP region end points and decay ratios. These calculated powerlflow points and decay ratios represent typical calculations for Clinton Power Station (CPS).
The plant- and cycle-specific calculations provide reasonable assurance that the thermal hydraulic stability as prescribed by Option I11 with respect to the size of the BSP regions is maintained with ITAs in the CPS core.
