- 10. Rod Withdrawal Error AOO 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 0.25' 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.

10The cycle-independent OLMCPR for the recirculation pump seizure event for GE14C is 1.44 based on the cycle-specific SLO SLMCPR. When adjusted for the off-rated power/flow conditions of SLO, this limit corresponds to a rated OLMCPR of 1.31. This limit does not require an adjustment for the SLO SLMCPR.
" Each application condition (Appl. Cond.) covers the entire range of licensed flow and feedwater temperature unless specified otherwise. The OLMCPR values presented apply to rated power operation based on the two loop operation safety limit MCPR.

- 15. Stability Analysis Results 15.1 Stability Option III Solution Nine Mile Point 2 has implemented BWROG Long Term Stability Solution Option III 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 15 Option III stability evaluation. Backup Stability Protection (BSP) regions are used by the plant in the event that the Option III OPRM system is declared inoperable.
The following Option Ill 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 Nine Mile Point 2 Cycle 15.
15.2 Detect and Suppress Evaluation A reload Option III 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 15 in accordance with the BWROG regional mode DIVOM guidelines described in Reference 4 in Section 15.4. The Cycle 15 Option III 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 15.2-2.
The relationship between the OPRM Successive Confirmation Count Setpoint and the OPRM Amplitude Setpoint is provided in Table E-I of Reference 3 in Section 15.4 and Table 15.2-1. 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 power and flow dependent LHGR multipliers are sufficient to provide adequate protection for the off-rated conditions from an ECCS-LOCA analysis perspective and there is no need for MAPLHGR multipliers, in addition to off-rated LHGR multipliers.
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.

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.

Nine Mile Point 2 000N2528-SRLR Reload 14 Revision 1 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 000N2528-SRLR Reload 14 Revision 1 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-1. 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 not required for this cycle. 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.

Nine Mile Point 2 000N2528-SRLR Reload 14 Revision 1 Appendix E Expanded Operating Domain Analysis 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). The MELLLA+ analysis is bounding for the MELLLA domain.
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 11 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.
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 standard domain.
Maximum Extended Load Line Limit Analysis The operating domain MELLLA was established for Nine Mile Point 2 in Reference E-2.
Increased Core Flow Operation with ICF throughout the operating cycle was justified for Nine Mile Point 2 in Reference E-3.
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 2 in Reference E-3.
EOC Recirculation Pump Trip Out of Service (EOC RPTOOS)
Operation with EOC RPTOOS was justified for Nine Mile Point 2 in Reference E-3.
Pressure Regulator Out of Service (PROOS)
Operation with PROOS was addressed for Nine Mile Point 2 from a thermal limits perspective only in Reference E-3.

Section 11 of this report presents the MCPR limits based on the TRACG04 methodology of Reference F-2.
The safety evaluation report for licensing topical report NEDE-32906P (Reference F-2) concluded that the application of TRACG04 methods to AOO and overpressure transient analyses were acceptable subject to certain limitations and conditions. Nine Mile Point 2 Cycle 15 is in compliance with these limitations and conditions.

Supplemental Information The safety evaluation for licensing topical report NEDC-33173P-A Revision 4 (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 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.
Limitation and Condition 9.10/9.11 (Transient LHGR 2/3)
Limitation and Condition 9.10 states:
"Each EPU and MELLLA+ fitel reload will document the calculation results of the analyses demonstratingcompliance to transient T-M acceptance criteria. The 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."
Limitation and Condition 9.11 states:
"To account for 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 fiel centerline melt and the 1 percent cladding circumferentialplastic strain acceptance criteria due to pellet-cladding mechanical interactionfor all of limiting 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 pressurization events). If the void history bias is incorporated into the transient model within the code, then the additional 10 percent margin to the fitel centerline melt and the 1 percent cladding circumferentialplastic strain is no longer required."
Appendix B documents the fact that the results for all analyzed transients demonstrate compliance with thermal-mechanical acceptance criteria.
Table G-1 summarizes the percent margin to the Thermal Overpower and Mechanical Overpower acceptance criteria.
As referenced in Appendix F 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 is 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 percentfor 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 firaction remains below 5 percent at all LPRM levels when operating at steady-state conditions within the MELLLA + upper boundary.
The highest calculated bypass voiding at any LPRM level will be provided with the plant-specific SRLR. "
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 calibrationerrors 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 calibration values for the different long-term solutions are specified in the associatedsections of this SE, discussing the stability methodology. "
The OPRM system will incorporate a 5% calibration error on the OPRM setpoints to address the bypass voiding uncertainty at low-flow conditions. This calibration error has been included in the OPRM amplitude setpoints. However, the APRM calibration error required by this limitation and condition is not applicable.

Nine Mile Point 2 000N2528-SRLR Reload 14 Revision 1 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 correlation to demonstrate the accuracy andpetformance of the void-qualitv 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-2). Therefore, the OLMCPR adder is not applied to Nine Mile Point 2 Cycle 15.
