10. Local Rod Withdrawal Error (With Limiting Instrument Failure) AQO Summary The rod withdrawal error (RWE) event in the maximum extended operating domain was originally analyzed in the GE BWR Licensing Report, Marimumn Extended Operating Domain Analysis for Brunswick Steam Electric Plant, NEDC-31654P, February 1989. The MCPRs for Brunswick Unit I Cycle 15 RWE are not generally bounded by the safety limit adjusted operating limit MCPRs in Table 10-5(a) or 10-5(b) of NEDC-31654P. The limiting results are shown in the table below for the RBM System setpoints shown in Table 10-5(c) of NEDC-31654P. The RBM operability requirements specified in Section 10.5 of NEDC-31654P have been evaluated to ensure that the Safety Limit MCPR and cladding 1% plastic strain criteria will not be exceeded in the event of an unblocked RWE event. The minimum OLMCPR with RBM inoperable, after cycle-specific SLMCPR adjustment, is 1.45 (=1.40*1.11/1.07).

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 Due to the Potential Reportable Condition (PRC 0 1-07) reported by GE on the DIVOM (Delta CPR Over Initial CPR Versus Oscillation Magnitude) slope issue, it is essential to confirm that the generic DIVOM slope used in this Option III stability analysis be applicable to Brunswick Unit I Cycle 15 or an interim OPRM setpoint be used based on a revised DIVOM slope. Should the Option 111 OPRM system be declared inoperable, the BWROG Interim Corrective Action will constitute the stability licensing basis for Brunswick Unit I Cycle 15.

Stability Option III Brunswick Unit I has implemented BWROG Long Term Stability Solution Option III (Oscillation Power Range Monitor-OPRM) as described in NEDO-31960-A, BTVR Owners Group Long-Term Stability Solutions Licensing Methodology, November 1995. Plant specific analysis incorporating the Option III hardware is described in GE-NE-C51-00251-00-01, Revision 0, Licensing Basis Hot Bundle Oscillation MagnitudeforBrunswickI and2, March 2001.

Reload validation has been performed in accordance with NEDO-32465-A, Reactor Stability Detect and Suppress Solutions Licensing Basis Methodology for Reload Application, August 1996. The stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint 17Includes a 0.02 penalty due to variable water gap R-factor uncertainty.

lxzuuu 1A I- Revision 0 in the following table. The two conditions evaluated are for a postulated oscillation at 45% 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.

The stability-based OLMCPR was calculated for Cycle 15. The reload validation calculation demonstrated that reactor stability does not produce the limiting OLMCPR for Cycle 15 as long as the selected OPRM setpoint produces values for OLMCPR(SS) and OLMCPR(2PT) which are less than the corresponding acceptance criteria.

Reload 14 Revision 0 Appendix B Decrease in Core Coolant Temperature Events The Loss of Feedwater Heating (LFWH) event and the Inadvertent HPCI start-up event are the only cold water injection AQOs checked on a cycle-by-cycle basis.

The LFWH event was analyzed for Brunswick Unit I Cycle 15 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 I Cycle 15 in accordance with Reference B-I.

BRUNSWICK UNIT I 0000-001 6-6502-SRLR Reload 14 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 SRVs in service. For MSIVOOS, the OLMCPRs presented in Section 11 and peak overpressure results in Section 12 are bounding. MSIVOOS will not be allowed while operating in the MELLLA+ domain (see Appendix F).

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 F).

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 I1.

Reference C4 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with all Turbine Bypass Valves Out of Service (TBPOOS). 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-3 and C-6. The safety limit change for Brunswick Unit I Cycle 15 from the reference safety limits used in References C-6 and C-3 requires an adjustment to the MCPR(p) below P-bypass limits and MCPR(f) limits. Further, the implementation of TRACG (Reference C-7) requires an adjustment to the K(P) above P-bypass.

The Reference C-6 MCPR(p) below P-bypass is increased for a Safety Limit of 1.1I by the ratio of (I41 J. The power-dependent limits in Figure C-I and Figure C-2 apply to all fuel types in the core.

The following coefficients apply for all fuel types in the core:

(% of Rated) A(f) B(i) Flow Intercept MCPR

(% of Rated) 102.5 -0.592 1.717 80.51 1.24 107.0 -0.608 1.760 85.61 1.24 112.0 -0.625 1.812 91.64 1.24 117.0 -0.656 1.877 97.10 1.24 The flow-dependent MAPLHGR limit multiplier, MAPFAC(f), is not altered for Brunswick Unit I Cycle 15.

Since the cycle-specific SLO SLMCPR is equal to 1.12, per Reference C-5, the TLO OLMCPR must be greater than or equal to 1.32 (to ensure that the SLO OLMCPR is greater than or equal to 1.40). From Reference C-5, the initial power for the licensing basis pump seizure event is 2143 MW4h, or 73.3% of licensed thermal power for Brunswick Unit I Cycle 15. The K(P) for this power, from Figure C-I, is 1.12. Therefore, the required minimum TLO OLMCPR of 1.32 is conservative for Brunswick Unit I Cycle 15.

BRUNSWICK UNIT I 0000-0016-6502-SRLR Reload 14 Revision 0 Appendix E Normal and Reduced Feedwater Temperature Limits In some cases, a distinction is made between the OLMCPR values for the normal feedwater temperature (NFWT) and reduced feedwater temperature (RFWT) domains. Specifically, for EOFPC15-5029 MWd/MT to EEOC15, the NFWT and RFWT limits are specified separately. Further, the NFWT and RFWT limits are separated at any cycle exposure for which the TBPOOS operating flexibility option is employed. The RFWT limits, when specified separately from the NFWT limits, apply to both feedwater temperature reduction and feedwater heater out of service. The results of the analyses are insensitive to feedwater temperature deviations of less than 100 F.

BRUNSWICK UNIT I 0000-00 1 6-6502-SRLR Reload 14 Revision 0 Appendix F MELLLA4 Implementation Brunswick is seeking approval to operate in the MELLLA+ domain, 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 I Cycle 15. 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 performed at MELLLA+ with I SRV out of service to ensure that both MELLLA and MELLLA+ are bounded. Finally, TBPOOS 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 I Cycle 15. The reload checklist as outlined in Reference F-2 is used to confirm that the DSS-CD is applicable to Brunswick Unit I Cycle 15 EPU/MELLLA+ operation.
