- 10. Rod Withdrawal Error AO0 Summary The Rod Withdrawal Error (RWE) is analyzed in NEDC-33286P, Nine Mile Point Nuclear Station Unit 2 APRM/RBM/Technical Specifications / Maximum Extended Load Line Limit Analysis (ARTS/MELLLA),
Revision 0, March 2007.
RWE Results:
RBM Setpoint (%) ACPR 108.0 0.23 111.0 0.25 114.0 0.25 117.0 0.29 Unblocked 0.257 The more limiting of the cycle specific and the generic ACPR values are reported in the table above. The RWE OLMCPR is determined by adding the ACPR for the desired RBM setpoint from the table above to the SLMCPR in Section 11.
The ARTS RWE analysis validated that the following MCPR values provide the required margin for full withdrawal of any control rod during this cycle:
For Power < 90% MCPR > 1.70 For Power > 90% MCPR >_1.40 The RBM operability requirements have been evaluated and shown to be sufficient to ensure that the SLMCPR and cladding 1% plastic strain criteria will not be exceeded in the event of a RWE.
7The cycle specific unblocked response is used to validate the MCPR operating limits for a full withdrawal provided in the paragraph below the table.

- 14. Control Rod Drop Analysis Results Nine Mile Point Unit 2 is a banked position withdrawal sequence plant, so the control rod drop accident analysis is not required. NRC approval is documented in NEDE-2401 1-P-A-US.
- 15. Stability Analysis Results Nine Mile Point Unit 2 is licensed to operate in the MELLLA+ operating domain. Operation within the MELLLA+ operating domain requires the use of the Detect and Suppress Solution - Confirmation Density (DSS-CD) stability solution. Stability results for operation at EPU with MELLLA+ and DSS-CD are contained in this section.
15.1 Stability DSS-CD Solution Nine Mile Point Unit 2 implements the stability DSS-CD solution using the Oscillation Power Range Monitor (OPRM) as described in Reference I in Section 15.4. Plant-specific analyses for the DSS-CD Solution are provided in Reference 2 in Section 15.4. The Detect and Suppress function of the DSS-CD 15 Includes a 0.02 penalty due to variable water gap R-factor uncertainty.
Page 17
NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 solution based on the OPRM system relies on the Confirmation Density Algorithm (CDA), which constitutes the licensing basis. The Backup Stability Protection (BSP) solution may be used by the plant in the event that the OPRM system is declared inoperable.
The CDA, enabled through the OPRM system, and the BSP solution described in Reference 2 in Section 15.4 provide the stability licensing bases for Nine Mile Point Unit 2 Cycle 15. The safety evaluation report for Reference I in Section 15.4 concluded that the DSS-CD solution is acceptable subject to certain limitations and conditions. These limitations and conditions are met for Nine Mile Point Unit 2 Cycle 15.
15.2 Detect and Suppress Evaluation A reload DSS-CD evaluation has been performed in accordance with the licensing methodology described in Reference 1 in Section 15.4 to confirm the Amplitude Discriminator Setpoint (SAD) of the CDA established in Reference 2 in Section 15.4. The Nine Mile Point Unit 2 Cycle 15 DSS-CD evaluation and the results for the DSS-CD Reload Confirmation Applicability Checklist documented in Table 15-1 demonstrate that: 1) the DSS-CD Solution is applicable to Nine Mile Point Unit 2 Cycle 15; and, 2) the SAD= 1 . 10 established in Reference 2 in Section 15.4 is confirmed for operation of Nine Mile Point Unit 2 Cycle 15.
The SAD=I. 1 0 setpoint is applicable to TLO and to SLO. The SAD=1'* 0 setpoint is applicable for a rated feedwater temperature equal to or greater than 420.5°F in the MELLLA+ domain per Reference 2 in Section 15.4.

The Manual BSP region boundaries and the BSP Boundary were calculated for Nine Mile Point 2 Cycle
- 15. The endpoints of the regions are defined in Table 15-2. The Scram Region boundary, the Controlled Entry Region boundary, and the BSP Boundary are shown in Figure 22.
The ABSP APRM Simulated Thermal Power setpoints associated with the ABSP Scram Region are provided for Cycle 15 and are defined in Table 15-3. These ABSP setpoints bound both TLO and SLO.

NRC approval of the PRIME methodology is contained in the Final Safety Evaluation of the PRIME model Licensing Topical Report provided in Section 16.4, Reference 2. The licensing basis results applicable to GE14C fuel type in the new cycle are summarized in the following table.

GEI4C 1580 < 1.00 < 0.10 The SAFER/PRIME ECCS-LOCA analysis results for GE14C fuel type are documented in Section 16.4, Reference I.
For GE14C, the small break Appendix-K ECCS-LOCA result at EPU power and rated core flow is 1561 °F as documented in Reference 1.
16.2 10CFR50.46 Error Evaluation All ECCS-LOCA errors up to 2011-03 and the SAFER/PRIME methodology are addressed in Section 16.4, Reference 1. Hence, there are no errors applicable to the new cycle for GE14C fuel type. The Licensing Basis PCT remains below the 10 CFR 50.46 limit of 2200 'F.
16.3 ECCS-LOCA Operating Limits The ECCS-LOCA MAPLHGR operating limits for GE14C fuel bundles in this cycle are shown in the following table.

The power and flow dependent LHGR multipliers are sufficient to provide adequate protection for the off-rated conditions from an ECCS-LOCA analysis perspective. The MAPLHGR multipliers can either be set to unity, or, set equal to the LHGR multipliers, which remain compliant with the basis of the ECCS-LOCA analysis with no loss of ECCS-LOCA margin.
The single loop operation multiplier on LHGR and MAPLHGR and the ECCS- LOCA analytical initial MCPR value applicable to the GE14C fuel type in the new cycle core are provided in the following table.

NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 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 steady-state operation and postulated AOOs. The fuel thermal-mechanical limits are met for the current cycle.

NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 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 11.

NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 Appendix D Off-Rated Limits Off-Rated Power Dependent Limits ARTS power dependent thermal limits have been confirmed for operation with Equipment In-Service, Turbine Bypass Valves Out-Of-Service (TBVOOS), Recirculation Pump Trip Out-Of-Service (RPTOOS) and Pressure Regulator Out-Of-Service (PROOS). The Kp/MCPRp and LHGRFACp thermal limits applicable to the Equipment In-Service, TBVOOS and RPTOOS conditions are documented in Reference D-4. The Kp/MCPRp and LHGRFACp thermal limits applicable to the PROOS condition are documented in References D-4 and D-2. The off-rated power dependent limits provided in References D-4 and D-2 have been validated for this cycle.
The MCPRp limits provided in References D-4 and D-2 are based on a SLMCPR of 1.07; therefore, a SLMCPR adjustment is required for this cycle. The off-rated power dependent limits have been scaled by (1.09/1.07). The Reference D-2 limits for PROOS below 55% power have been adjusted as a result of the shift in fuel thermal monitor threshold and scaling of Pbypass similar to the adjustment shown in Reference D-3.
The MCPRp and LHGRFACp limits below the turbine power/scram bypass setpoint of 26% rated power have only been evaluated for core flow less than or equal to 75% of rated core flow. Therefore, the MCPRp and LHGRFACp limits below 26% power are not applicable above 75% of rated core flow.
The LOSC report in Reference D-6 has been confirmed to be applicable to the MELLLA+ operating domain.

NINE MILE POINT 2 000N0123-SRLR Reload 14 Revision 2 Appendix E Expanded Operating Domain Analyses Expanded operating domain analyses were performed for Maximum Extended Load Line Limit Analysis Plus (MELLLA+) operation, Increased Core Flow (ICF) operation up to 105% of rated core flow, turbine bypass valve out-of-service (TBVOOS), recirculation pump trip out-of-service (RPTOOS), and pressure regulator out-of-service (PROOS).
Coastdown operation beyond full power to 40% power under conditions bounded by 105% core flow is conservatively bounded by the MCPR operating limits given in Section II of this document at the applicable core flow and feedwater temperature conditions in the expanded operating domain. The basis for this statement is contained in Reference E-1 & E-3.
100% Core Flow (Standard Domain)
It has been established that ICF and/or MELLLA+ domain results bound the standard (rated core flow) domain. Therefore, a cycle-specific analysis is not performed for the 100% rated core flow.
Maximum Extended Load Line Limit Analysis Plus The operating domain MELLLA+ was established for Nine Mile Point Unit 2 in Reference E-2.
Increased Core Flow Operation with ICF throughout the operating cycle was justified for Nine Mile Point Unit 2 in Reference E-2.
The MSIV closure event (flux scram) was analyzed at 100% rated thermal power and both 85% and 105% rated core flow at the rated dome pressure.
An operational band of - 20'F from nominal feedwater temperature is supported this cycle for all Application Conditions specified in Section 11.
Turbine Bypass Valve Out of Service (TBVOOS)
Operation with TBVOOS was justified for Nine Mile Point Unit 2 in Reference E-2.
EOC Recirculation Pump Trip Out of Service (EOC RPTOOS)
Operation with EOC RPTOOS was justified for Nine Mile Point Unit 2 in Reference E-2.
Pressure Regulator Out of Service (PROOS)
Operation with PROOS was addressed for Nine Mile Point Unit 2 from a thermal limits perspective only in Reference E-2.

Supplementary Information The safety evaluation for licensing topical report NEDC-33173P-A (Reference G-1) concluded that the application of GEH/GNF methods to expanded operating domains was acceptable subject to certain limitations and conditions. Several of these conditions request that additional, application-specific information be provided in the SRLR. The information provided below responds these requests for the identified items.
Limitation and Condition 9.5 (SLMCPR 2)
Limitation and Condition 9.5 states:
"For operation at MELLLA+, including operation at the EPU power levels at the achievable core flow state-point, a 0.01 value shall be added to the cycle-specific SLMCPR value for power-to-Ilow ratios up to 42 MWt/Mlbm/hr, and a 0. 02 value shall be added to the cycle-specific SLMCPR value for power-to-flow ratios above 42 MWt/Mlbrn/hr. "
For operation at MELLLA+, a 0.02 value was added to the cycle specific SLMCPR. The SLMCPR values reported in Section 11 reflect this adder.
Limitation and Condition 9.8 (ECCS-LOCA 2)
Limitation and Condition 9.8 states:
"The ECCS-LOCA will be performed for all statepoints in the upper boundary of the expanded operatingdomain, including the minimum core flow statepoints, the transition statepoint, as defined in Reference G-2 and the 55 percent core flow statepoint. The plant-specific application will report the limiting ECCS-LOCA results as well as the ratedpower andflow results. The SRLR will include both the limiting statepoint ECCS-LOCA results and the rated conditions ECCS-LOCA results. "
This limitation and condition is satisfied by the Appendix K PCTs reported in Reference 16.4. The SRLR reports the bounding Licensing Basis PCT for all statepoints analyzed.
Limitation and Condition 9.10 (Transient LHGR 2)
Limitation and Condition 9.10 states:
"Each EPU and MELLLA + fiuel reload will document the calculation results of the analyses demonstratingcompliance to transient T-M acceptance criteria. Tihe plant T-M response will be provided with the SRLR or COLR, or it will be reported directly to the NRC as an attachment to the SRLR or COLR. "

Mechanical Overpower 14.9%
Limitation and Condition 9.11 (Transient LHGR 3)
Limitation and Condition 9.11 states:
"To accountfor the impact of the void history bias, plant-specific EPU and MELLLA +
applicationsusing either TRACG or ODYN will demonstrate an equivalent to 10 percent margin to the fuel centerline melt and the 1 percent cladding circumferential plastic strain acceptance criteriadue to pellet-claddingmechanical interactionfor all oflimiting AO0 transient events, including equipment out-of-service. Limiting transients in this case, refers to transients where the void reactivity coefficient plays a significant role (such as pressurizationevents). If the void history bias is incorporatedinto the transient model within the code, then the additional 10 percent margin to the fiuel centerline melt and the I percent cladding circumferentialplastic strain is no longer required."
The void history bias was incorporated into the transient model within the TRACG04 code, and therefore the 10 percent margin to the fuel centerline melt and the 1 percent cladding circumferential plastic strain acceptance criteria are no longer required.
Limitation and Condition 9.17 (Steady-State 5 Percent Bypass Voiding)
Limitation and Condition 9.17 states:
"The instrumentationspecification design bases limit the presence of bypass voiding to 5 percent (LRPM (sic) levels). Limiting the bypass voiding to less than 5 percent for long term steady operation ensures that instrumentation is operated within the specification.
For EPU and MELLLA + operation, the bypass voiding will be evaluated on a cycle-specific basis to confirm that the void fraction remains below 5 percent at all LPRM levels when operating at steady-state conditions within the MELLLA+ upper boundary.
The highest calculatedbypass voiding at any LPRM level will be provided with the plant-specific SRLR. "
Page 61
NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 The bypass voiding was evaluated for the licensed core loading and confirmed that the bypass void fraction remained below 5 percent at all LPRM levels when operating at steady-state conditions within the licensed upper boundary.
Limitation and Condition 9.18 (Stability Setpoints Adjustment)
Limitation and Condition 9.18 states:
"The NRC staff concludes that the presence bypass voiding at the low-flow conditions where instabilities are likely can result in calibration errors of less than 5 percent for OPRM cells and less than 2 percentfor APRM signals. These calibrationerrors must be accounted for while determining the setpoints for any detect and suppress long term methodology. The calibrationvalues for the different long-term solutions are specified in the associatedsections of this SE, discussing the stability methodology."
This limitation and condition is not applicable to DSS-CD because the significant conservatisms in the current licensing methodology and associated MCPR margins are more than sufficient to compensate for the overall uncertainty in the OPRM instrumentation.
Limitation and Condition 9.19 (Void-Quality Correlation 1)
Limitation and Condition 9.19 states:
"For applications involving PANCEA(sic)/ODYN/ISCORITASC for operation at EPU and MELLLA+, an additional 0.01 will be added to the OLMCPR, until such time that GE expands the experimental database supporting the Findlay-Dix void-quality correlationto demonstrate the accuracy and performance of the void-quality correlation based on experimental data representative of the current fuel designs and operating conditions duringsteady-state, transient,and accident conditions."
The OLMCPR limitation requiring an additional 0.01 adder on the OLMCPR does not apply to EPU or MELLLA+ licensing calculations when TRACG04 methods are used (Reference G-3). Therefore, the OLMCPR adder is not applied to NMP2 Cycle 15.

Supplementary Information The safety evaluation for licensing topical report NEDC-33006P-A Revision 3 (Reference H-i) approved the operation of GE BWRs in the MELLLA+ expanded operating domain, subject to certain limitations and conditions. Several of these limitations and conditions request that additional, application-specific information be provided in the SRLR. The information provided below responds to these requests for the identified items.
The pressurization transients are generally limiting at high core flow conditions. However, the transients were performed at both the minimum MELLLA+ flow (85%) and the maximum ICF flow (105%). This ensures that the pressurization transient results bound MELLLA, MELLLA+ and ICF operating conditions. Additionally, the loss of feedwater heating (LFWH) transient, which is more limiting at low core flow, was performed at the minimum MELLLA+ flow. Therefore, the limiting subcooling transient bounds MELLLA, MELLLA+ and ICF operating conditions. Single loop operation (SLO) will not be allowed in conjunction with operation in the MELLLA+ domain.
Limitation and Condition 12.6 (SLMCPR Statepoints and CF Uncertainty)
Limitation and Condition 12.6 states:
"Until such time when the SLMCPR methodology (References H-2 and H-3) for off-rated SLMCPR calculation is approved by the stafffor MELLLA + operation, the SLMCPR will be calculatedat the rated statepoint (120 percent P/I00 percent CF), the plant-specific minimum CF statepoint (e.g., 120 percent P/80 percent CF), and at the 100 percent OLTP at 55 percent CF statepoint. The currently approved off-rated CF uncertainty will be used for the minimum CF and 55 percent CF statepoints. The uncertainty must be consistent with the CF uncertainty currently applied to the SLO operation or as NRC-approved for MELLLA+ operation. The calculated values will be documented in the SRLR. "
As requested, the SLMCPR calculated results at specified off-rated power/flow conditions are reported in Table H-i below, including the low CF statepoint.

Limitation and Condition 12.10.b states:
"LOCA analysis is not peiformed on cycle-specific basis; therefore, the thermal limits applied in the A'I+SAR LOCA analysisfor the 55 percent CF MELLLA + statepoint and/or the transition statepoint must be either bounding or consistent with cycle-specific off-rated limits. The COLR and the SRLR will contain confirmation that the off-rated limits assumed in the ECCS-LOCA analyses bound the cycle-specific off-rated limits calculated for the MELLLA + operation. Every future cycle reload shall confirm that the cycle-specific off-rated thermal limits applied at the 55 percent CF and/or the transition statepoints are consistent with those assumed in the plant-specific ECCS-LOCA analyses. "
The off-rated limits assumed in the ECCS-LOCA analyses are confirmed to be consistent with the cycle-specific off-rated LHGR multipliers calculated for the MELLLA+ operation.
Limitation and Condition 12.18.d (ATWS TRACG Analysis)
Limitation and Condition 12.18.d states:
"In general, the plant-specific application will ensure that operation in the MELLLA+
domain is consistent with the assumptions used in the ATWS analysis, including equipment out of service (e.g., FWHOOS, SLO, SRVs, SLC pumps, and RHR pumps, etc.).
If assumptions are not satisfied, operation in MELLLA+ is not allowed. The SRLR will specify the prohibitedflexibility options for plant-specific MELLLA + operation, where applicable. For key input parameters, systems and engineering safety features that are important to simulating the ATWS analysis and are specified in the Technical Specification (TS) (e.g., SLCS parameters,A TWS RPT, etc.), the calculation assumptions must be consistent with the allowed TS values and the allowedplant conifiguration. If the analyses deviate from the allowed TS configurationfor long term equipment out of Page 64
NINE MILE POINT 2 00ON0123-SRLR Reload 14 Revision 2 service (i.e., beyond the TS LCO), the plant-specific application will specify andjustify the deviation. In addition, the licensee must ensure that all operability requirements are met (e.g., NPSH) by equipment assumed operable in the calculations."
This ATWS TRACG Analysis limitation and condition requires that the SRLR specify the prohibited flexibility options for plant-specific MELLLA+ operation, where applicable, as expressed by EOOS options in Section 8.
