NGG Nuclear Fuels Mgmt. & Safety Analysis B2C1 8 Core Operating Limits Report Design Cale. No. 21321-1267 Page 5, Revision 0 Introduction and Summary CAUTION References to COLR Figures or Tables should be made using titles only; figure and table numbers may change from cycle to cycle.

This report provides the values of the power distribution limits and control rod withdrawal block instrumentation setpoints for Brunswick Unit 2, Cycle 18 as required by TS 5.6.5. Revision 0 of this report supports operation at up to 2923 MWt. The main changes are those associated with the thermal limits and Power-Flow maps.

OPERATING LIMIT REQUIREMENT Average Planar Linear Heat Generation Rate (APLHGR) limits TS 5.6.5.a.1 (with associated core flow and core power adjustment factors)

Minimum Critical Power Ratio (MCPR) limits TS 5.6.5.a.2 (with associated core flow and core power adjustment factors)

Period Based Detection Algorithm (PBDA) Setpoint for Function 2.f of TS 3.3. 1. 1, TS 5.6.5.a.3 Oscillation Power Range Monitor (OPRM)

Allowable Values and power range setpoints for Rod Block Monitor Upscale TS 5.6.5.a.4 Functions of TS 3.3.2.1 Per TS 5.6.5.b and 5.6.5.c, these values have been determined using NRC approved methodology and are established such that all applicable limits of the plant safety analysis are met. The limits specified in this report support single recirculation loop operation (SLO) as required by TS LCO 3.4.1 and inoperable Main Turbine Bypass System as required by TS 3.7.6.

In order to support the Stability Option III with an inoperable OPR.M scram function, the following is also included in this report:

OPERATING LIMIT REQUIREMENT BWROG Interim Corrective Action Stability Regions TS LCO 3.3. 1. 1, Condition I This report conforms to Quality Assurance requirements as specified in Reference 1.

Sin2le Loop Operation Brunswick Unit 2, Cycle 18 may operate over the entire MEOD range with SLO over the entire cycle as permitted by TS 3.4.1 with applicable limits specified in the COLR for TS LCO's 3.2. 1, and 3.2.2.

The applicable limits are:

LCO 3.2. 1, Average Planar Linear Heat Generation Rate (APLHGR) Limits: per Reference 1, the Figures 9 and 10 described in the APLHGR Limits section below include a SLO limitation of 0. 8 on the MAPLHGR(F) and MAPLHGR(P) multipliers.

NGG Nuclear Fuels Mgmt. & Safety Analysis Design Caic. No. 21321-1267 B2C18 Core Operating Limits Report Page 6, Revision 0 LCO 3.2.2, Minimum Critical Power Ratio (MCPR) Limits: per Reference 1, Table 1 and Figures 11I and 12, the MCPR limits presented apply to SLO without modification.

Various indicators on the Power/Flow maps are provided not as operating limits but rather as a convenience for the operators: a single ioop operation (SLO) Entry Rod Line is shown on the two ioop operation maps to avoid regions of instability in the event of a pump trip; a maximum core flow line is shown on the single loop operation maps to avoid vibration problems; a maximum core power of 50%

RTP in SLO mitigates a spurious trip signal which could result from APRM noise;, and Average Power Range Monitors (APRM) Simulated Thermal Power (STP) Scram and Rod Block nominal trip setpoint limits are shown to illustrate where these setpoints occur. Note that the APRM STP setpoints are only approximations, shown at the estimated core flow corresponding to the actual drive flow-based setpoints. The approximations serve to indicate where the operator may encounter the APRMSTP -

High Allowable Value setpoints (LCO 3.3. 1. 1, Table 3.3. 1. 1-1: Reactor Protection System Instrumentation, Function 2. b).

Inoperable Main Turbine Bypass System Brunswick Unit 2, Cycle 18 may operate with an inoperable Main Turbine Bypass System in accordance with TS 3.7.6 with applicable limits specified in the COLR for TS LCO 3.2.1 and LCO 3.2.2. The applicable limits are as follows:

LCO 3.2. 1, Average Planar Linear Heat Generation Rate (APLHGR) Limits: in accordance with Reference 1 as shown in Figure 10, TBPOOS does not require an additional reduction in the MAPLGHR(P) limits, as the Turbine Bypass Operable and Inoperable limits are identical.

LCO 3.2.2, Minimum Critical Power Ratio (MCPR) Limits: in accordance with Reference 1, TBPOOS does not require an additional increase in the MCPR(P) multiplier as shown in Figure 12, as the Turbine Bypass Operable and Inoperable limits are identical. TBPOOS requires increased MCPR limits, included in Table 1.

The system response time assumed by the safety analyses from event initiation to start of bypass valve opening is 0.10 seconds, with 80% of the bypass flow capacity achieved in 0.30 seconds Although the Turbine Bypass Out-of-Service (TBPOOS) analysis supports operation with all bypass valves inoperable for the entire maximum extended operating domain (MEOD) range and up to 1 I100F rated equivalent feedwater temperature reduction, three or more turbine bypass valves inoperable renders the Main Turbine Bypass System inoperable.

Feedwater Temperature Reduction A variation within 1 0O F of nominal feedwater temperature or a power level less than 3 0% RTP has been evaluated as being in compliance with normal feedwater temperature operating limits. AI feedwater temperature reduction in excess of 1 0O F together with the reactor power at a minimum of 30% rated requires the use of the Reduced FWTR MCPR limits (Table 1) and Stability Option III Power/Flow limits (Figures 17 and 18).

NGG Nuclear Fuels Mgmt. & Safety Analysis Design Caic. No. 21321-1 267 B2C18 Core Operating Limits Report Page 7, Revision 0 APLHGR Limits The limiting APLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of planar average exposure is given in Figures 1 through 7. These values were determined with the SAFER/GESTR LOCA methodology described in GESTAR-11 (Reference 2).

Figures 1 through 7 are to be used only when hand calculations are required as specified in the bases for TS 3.2. 1. Hand calculated results may not match a POWERPLEX calculation since normal monitoring of the APLHGR limits with POWERPLEX uses the complete set of lattices for each fuel type provided in Reference 3.

The core flow and core power adjustment factors for use in TS 3.2.1 are presented in Figures 9 and 10.

For any given flow/power state, the minimum of MAPLHGR(F) determined from Figure 9 and MAPLHGR(P) determined from Figure 10 is used to determine the governing limit.

MCPR Limits The Scram Speed MCPR OPTION A, OPTION B, and non-pressurization transient MCPR limits for use in TS 3.2.2 for each fuel type as a function of cycle average exposure are given in Table 1. These values were determnined with the GEMINI(TRACG) methodology and GEXL14 critical power correlation described in GESTAR-11 (Reference 2) without assuming EOC-RPT, and are consistent with a Safety Limit MCPR of 1. 11 specified by TS 2.1.1.2.

The core flow and core power adjustment factors for use in TS 3.2.2 are presented in Figures I11 and

12. For any given power/flow state, the maximum of MCPR(F) determined from Figure 11I and MCPR(P) determined from Figure 12 is used to determine the governing limit. All MCPR limits presented in Table 1, Figure 11I and Figure 12 apply to two recirculation pump operation (TLO) and SLO without modification.

RBM Rod Block Instrumentation Setpoints The nominal trip setpoints and allowable values of the control rod withdrawal block instrumentation for use in TS 3.3.2.1 (Table 3.3.2. 1-1) are presented in Table 2. These values were determined to be consistent with the bases of the ARTS program, and the determination of MCPR limits with the GEMINI(TRACG) methodology and the GEXL-PLUS critical power correlation described in GESTAR-11 (Reference 2) as well as the NUMAC PRNM system as discussed in Reference 8. The table also includes the cycle-specific MCPR limits regarding the required operability of the RBM, consistent with Technical Specification Table 3.3.2. 1 -1.

Stability Option III Brunswick Unit 2 has implemented BWROG Long Termn Stability Solution Option III using Oscillation Power Range Monitors (OPRMs) with the methodology described in Reference 4. Plant specific analysis incorporating the Option III hardware is described in Reference 5. Reload validation has been performed in accordance with Reference 6. The resulting stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint in Table 3. If desirable, Table 3 would support higher stability limits for various MCPR operating limits greater than the least limiting AQO OLMCPR values provided in Table 1 or Figures I11 or 12, but the suggested stability setpoints ensure no OLMCPR restrictions from Option III. Table 3 shows that for an OPRM setpoint

NGG Nuclear Fuels Mgmt. & Safety Analysis Design Caic. No. 21321-1267 B2C18 Core Operating Limits Report Page 8, Revision 0 (Amplitude Setpoint Sp) of 1. 13, OLMCPR(SS) is less restrictive than Figure 11I at 45% maximum flow or Figure 12 at 60.6% maximum power. Table 3 also shows that OLMCPR(2PT) is less restrictive than any limiting Table I OLMCPR for Sp equal to 1. 13. Therefore the OPRM Period Based Detection Algorithm (PBDA) setpoint limit for Amplitude Sp referenced by fuinction 2.f of Table 3.3. 1. 1-1 of Technical Specification 3.3. 1.1 is 1. 13 for Cycle 18. Per Table 3-2 of Reference 6, an Sp value of 1. 13 supports selection of a Confirmation Count Setpoint NP of 15 or less.

Stability Option III also affects the power/Flow maps as described below.

Power/Flow Maps

'Six Power/Flow maps for use at up to 2923 MWt (Figures 13-18) were developed based on References 1 and 7 to facilitate operation under Stability Option III as implemented by LCO 3.3.1..1, Condition I and function 2.f of Table 3.3.1.1-1 of the Technical Specifications. All six maps illustrate the region of the power/flow map above 25% power and below 60% drive flow (which is approximately 63-64%

core flow) where the system is required to be enabled. [Note that the power/flow maps can only approximate the licensed Enabled Region, because the maps display core flow, while the Enabled Region is based on drive flow]

Figures 13, 15 and 17 support an operable OPRM function 2.f and Figures 14, 16 and 18 support an inoperable OPRM function 2.f for TLO, SLO or FWTR, respectively. Each figure for an operable OPRM shows a Scram Avoidance Region where the OPRM system may generate a scram to avoid an instability event. The figures for an inoperable OPRM event show the additional stability regions which address BWROG-94078 Interim Corrective Actions required to support LCO 3.3. 1. 1, Condition I. Figures 14, 16 and 18 for OPRIV inoperable also includes a 5% Buffer Region around the Immediate Exit Region as an operator aid [Note for Figure 16 (SLO), the 5% Buffer Region does not fully enclose the Immediate Exit Region as on Figures 14 and 18].

Figures 15 and 16 for SLO show the maximum allowable core flow at 45 Mlbs/hr and has the STP scram and rod block limits appropriately reduced. Note that the STP scram and rod block limits are defined in Technical Specifications, the Technical Requirements Manual, and Plant procedures.

Figures 15 and 16 also implement the corrective action for A/R 217345217345which restricts reactor operation to no more than 50% RTP in SLO with OPRM operable or inoperable. This operator aid is intended to mitigate a spurious trip signal which could result from APRM noise while operating at high power levels.

Figures 17 and 18 for FWTR differ from ILO and SLO by including extended scram regions to provide additional stability protection. Although the scram region for SLO above 50% RTP is more restrictive, intentional operation with SLO and FWTR is prohibited.

10. Local Rod Withdrawal Error (With Limiting Instrument Failure) AOO Summary The rod withdrawal error (RWE) event in the maximum extended operating domain was originally analyzed in the GE BWR Licensing Report, Maximum Extended Operating Domain Analysis for Brunswick Steam Electric Plant, NEDC-3 1654P, February 1989. The Brunswick Unit 2 Cycle 18 RWE MCPRs for the 108%, 111 %, and 114% RBM system setpoints are not generally bounded by the safety limit adjusted operating limit MCPRs in Tables 10-5(a), 10-5(b), and 10-5(c) of NEDC-3 1654P. However, the RWE MCPR for the 117% RBM system setpoint is bounded by the safety limit adjusted operating limit MCPR in Table 10-5(c) of NEDC-3 1654P. The limiting results are shown in the table below for the 108%, 111%,

114%, and 117% RBM system setpoints. The RBM operability requirements specified in Section 10.5 of NEDC-3 1654P (for RBM inoperable: OLMCPR Ž: 1.45 for power Ž: 90% and OLMCPR Ž! 1.76 for power

< 90% for a SLMCPR of 1. 11) have been evaluated and shown to be sufficient to ensure that the Safety Limit MCPR will not be exceeded in the event of an unblocked RWE event. In addition, the cladding 1%

plastic strain criteria have been met.

14. Control Rod Drop Analysis Results This is a banked position withdrawal sequence plant, therefore, the control rod drop accident analysis is not required. NRC approval is documented in NEDE-2401 1-P-A-US.
15. Stability Analysis Results 15.1 Introduction The BWROG Regional Mode DIVOM Guideline recommends that a plant specific DIVOM slope be used for Option III OPRM setpoint determination (Reference 1 in Section 15.4). However, since Brunswick Unit 2 will be implementing the Detect and Suppress Solution - Confirmration Density (DSS-CD) solution in the near future, the interim DIVOM approach as a function of Figure of Merit will be applied until DSS-CD is implemented (Reference 2 in Section 15.4).

Should the Option III OPRM system be declared inoperable, the BWROG Interim Corrective Action will constitute the stability licensing basis for Brunswick Unit 2 Cycle 18.

15.2 Stability Option III Brunswick Unit 2 has implemented BWROG Long Term Stability Solution Option III (Oscillation Power Range Monitor-OPRM) as described in Reference 3 in Section 15.4. Plant specific analysis incorporating the Option III hardware is described in Reference 4 in Section 15.4. Reload validation has been performed in accordance with the licensing basis methodology described in Reference 5 in Section 15.4. The stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint in the following table. The two conditions evaluated are for a postulated oscillation at 45% rated core flow steady state operation (SS) and following a two recirculation pump trip (2PT) from the limiting full power operation state point.

Current power and flow dependent limits provide adequate protection against violation of the Safety Limit MCPR for postulated reactor instability as long as the operating limit is greater than or equal to the specified value for the selected OPRM setpoint.

17 Includes a 0.02 penalty due to variable water gap R-factor uncertainty.

Page 13

Brunswick Unit 2 Reload 17 0000-0052-0675-SRLR Revision 0 The stability-based OLMCPR was calculated for Cycle 18. The reload validation calculation demonstrated that reactor stability does not produce the limiting OLMCPR for Cycle 18 as long as the selected OPRM setpoint produces values for OLMCPR(SS) and OLMCPR(2PT) that are less than the corresponding acceptance criteria. The OPRM setpoints for Two Loop Operation (TLO) are conservative relative to Single Loop Operation (SLO) and are therefore bounding.

Regions of restricted operation defined in Attachment I of Reference 7 in Section 15.4 and expanded in Reference 6 in Section 15.4, are applicable to Brunswick Unit 2. The standard ICA stability regions are expanded as appropriate to offer stability protection for Brunswick Unit 2 Cycle 18 in accordance with Reference 8 in Section 15.4.

18 The off-rated OLMCPR is the maximum of the Kp adjusted MCPR or the MCPRf at 45% core flow.

Brunswick Unit 2 Reload 17 0000-0052-0675-SRLR Revision 0 Appendix B Decrease in Core Coolant Temperature Events The Loss of Feedwater Heating (LFWH) event was analyzed for Brunswick Unit 2 Cycle 18 using the BWR Simulator Code. The use of this code is permitted in GESTAR 11. 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.

In addition, the Inadvertent HPCI start-up event was shown to be bounded by the LFWH event in Brunswick Unit 2 Cycle 18 in accordance with Reference B-i1.

Brunswick Unit 2 0000-0052-0675-SRLR Reload 17 Revision 0 Appendix C Operating Flexibility Options Reference C-I provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with one Main Steamline Isolation Valve Out of Service (MSIVOOS) (three steamline operation) and all S/RVs in service.

For MSIVOOS, the OLMCPRs presented in Section I11 and peak overpressure results in Section 12 are bounding. MSIVOOS will not be allowed while operating in the MELLLA+ domain (See Appendix E).

Reference C-2 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with Feedwater Temperature Reduction (FWTR).

The required OLMCPRs are provided in Section 11.

FWTR and FWHOOS will not be allowed while operating in the MELLLA+ domain (See Appendix E).

Reference C-3 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with Maximum Extended Operating Domain (MEOD). The required OLMCPRs are provided in Section 11.

Reference C-4 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with all Turbine Bypass Valves Out of Service (TBVOOS). The required OLMCPRs are provided in Section 11.

The impact of GE14 fuel on the operating flexibility options is addressed in Reference C-5.

The ARTS power and flow dependent operating limits for all operating flexibility options are provided in References C-9, C-3, and C-6.

The ARTS power and flow dependent MCPR limits apply to two recirculation pump system operation and SLO without modification for Brunswick Unit 2 Cycle 18.

The ARTS power dependent limits in Reference C-9 include an adjustment to the limits provided in References C-3 and C-5 to address the 10 CFR Part 21 Communication in Reference C-8. The power dependent MCPR limits in Reference C-9 also include an adjustment to the Kp above P-bypass due to the implementation of TRACG (Reference C-7). The MCPRp limits provided in Reference C-9 are based on a Safety Limit of 1. 11. The Reference C-9 power dependent limits are not altered for Brunswick Unit 2 Cycle 18.

The ARTS flow dependent limits provided in Reference C-3 are based on a Safety Limit of 1.07. Due to the cycle-specific safety limit adjustment for Brunswick Unit 2 Cycle 18, there will be a required adjustment to the MCPRf limits and a validation of the required minimum GE14 OLMCPR for the recirculation pump seizure event. The Reference C-3 MCPRf limits are increased for a Safety Limit of 1.11 by the ratio of (1.11/1.07). The following coefficients apply:

Brunswick Unit 2 0000-0052-0675-SRLR Reload 17 Revision 0 The flow dependent MAPLHGR limit multiplier, MAPFACf, is not altered for Brunswick Unit 2 Cycle 18.

From Reference C-5, the SLO OLMCPR was determined to be 1.40 with a SLO SLMCPR of 1. 12. The initial power for the licensing basis pump seizure event is 2143 MWth, which was about 83.8% of the plant licensed thermal power at the time of the analysis.

Consequently, the Kp for this power level from Reference C-5 was approximately 1.06, resulting in a minimum full power OLMCPR of 1.32 to cover the pump seizure event for GEl14 fuel for a SLO SLMCPR of 1. 12. After EPU, the licensing basis GE 14 pump seizure initial power in MWth is unchanged, but represents about 73.3% of licensed thermal power, resulting in a Kp of about 1. 12. Since the SLO SLMCPR is 1. 13 for Brunswick Unit 2 Cycle 18, the SLO OLMCPR must be greater than or equal to 1.41 for the pump seizure event. Therefore, the minimum GE14 OLMCPR of 1.35 (See Section 11) is conservative for the SLO pump seizure event (l.35*K(73.3)=

1.35*1.12 =1.51 >1.41).

.Appendix E MELLLA+ Implementation Brunswick is seeking approval to operate in the MELLLA+ domain (Reference E-1), which would provide greater core flow flexibility, particularly as power approaches 120% of the original licensed thermal power (OLTP).

Approval is not expected prior to startup of Brunswick Unit 2 Cycle 18.

However, the cycle-specific reload licensing analyses were performed to support operation with or without the MELLLA+ domain. Special consideration of MELLLA+ was given during performance of the transient analyses, stability analyses, and LOCA analyses.

The pressurization transients are generally limiting at high flow conditions. However, the transients were performed at both the minimum MELLLA+ flow (85%) and the maximum ICF flow (104.5%). This ensures that the pressurization transient results bound both MELLLA and MELLLA+. Additionally, the loss of feedwater heating (LFWH) transient, which is more limiting at low flow, was performed at the minimum MELLLA+ flow.

Therefore, the limiting subcooling transient bounds both MELLLA and MELLLA+. Reduced feedwater temperature (FFWTR and FWHOOS) and single loop operation (SLO) will not be allowed in conjunction with operation in the MELLLA+ domain. Further, no SRVs will be allowed to be out of service in the MELLLA+ domain.

However, the pressurization transients were performned at MELLLA+ with 1 SRV out of service to ensure that both MELLLA and MELLLA+ are bounded. Finally, TBVOOS will be allowed in the MELLLA+ domain, but MSIVOOS will not.

For EPU/MELLLA+ operation, the Detect and Suppress Solution - Confirmation Density (DSS-CD) is the licensing basis for Brunswick Unit 2 Cycle 18. The reload checklist as outlined in Reference E-2 and shown in Table E-1 is used to confirm that the DSS-CD is applicable to Brunswick Unit 2 Cycle 18 EPU/M\\ELLLA+ operation.

The appropriate BSP Option may be implemented based on the inform-ation provided in Reference E-3.

The application of the ECCS-LOCA analysis to operation in the MELLLA+ power/flow region was addressed in Reference E-4. Elimination of the 1 600'F Upper Bound peak cladding temperature limit has been incorporated as defined in Reference E-5.
