The pressure relief and safety valve configuration for this plant are presented in Table A-2. Additionally, the operating flexibility options listed in Section 8 are supported by the reload licensing analysis 14 Table A-1 Reactor Operating Conditions Analysis Value Parameter ICF LCF ICF LCF NFWT NFWT RFWT RFWT Thermal power, MWt 3458.0 3458.0 3458.0 3458.0 Core flow, Mlb/hr 107.6 83.0 107.6 83.0 Reactor pressure (core mid-plane), psia 1066.0 1061.5 1057.7 1053.4 Inlet enthalpy, Btu/lb 526.0 518.2 519.7 510.3 Non-fuel power fraction 0.036 0.036 0.036 0.036 Steam flow, Mlb/hr 14.17 14.14 13.26 13.23 Dome pressure, psig 1035.0 1035.0 1027.4 1027.4 Turbine pressure, psig 988.8 989.0 986.8 986.9 Table A-2 Pressure Relief and Safety Valve Configuration Valve Type Number of Lowest Setpoint Valves (psig)

Page 186

BROWNS FERRY 1 0000-0044-1520-SRLR Reload 6 Revision 0 Appendix B Decrease in Core Coolant Temperature Events The Loss-of-Feedwater Heating event was analyzed at 100% rated power using the BWR Simulator Code. The use of this code is permitted in GESTAR II. 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 accordance with Determination of Limiting Cold Water Event, NEDC-32538P-A, February 1996. The Inadvertent HPCI with a Turbine Trip results are presented in Sections 9 and 11 and have been confirmed to be bounded by other pressurization events for Browns Ferry Unit 1 Cycle 7.

Page 187

BROWNS FERRY 1 0000-0044-1520-SRLR Reload 6 Revision 0 Appendix C Expanded Operating Domain Analyses To provide Browns Ferry Nuclear Plant Unit 1 with operating improvements, expanded operating domain analyses were performed for maximum extended load line limit (MELLL) operation (81% flow),

increased core flow (ICF) operation up to 105% of rated flow, final feedwater temperature reduction (FFWTR) and feedwater heaters out-of-service (FWHOOS) were performed at a temperature of 327.0'F

(-54.7°F at rated power), turbine bypass valves out-of-service (TBVOOS), and recirculation pump trip out-of-service (RPTOOS). In addition, in the event of power load unbalance failure (PLUOOS), limits have also been provided.

Coastdown operation beyond full power operation to 40% power 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 (Reference C-1).

Maximum Extended Load Line Limit The operating domain MELLL was established for Browns Ferry Nuclear Plant Unit 1 in Reference C-2.

Increased Core Flow and Final Feedwater Temperature Reduction Operation with ICF throughout the operating cycle and with ICF and FFWTR at the end of the operating cycle was justified for Browns Ferry Nuclear Plant Unit 1 in Reference C-3.

Feedwater Heaters Out-of-Service (FWHOOS)

Operation with FWHOOS (-54.7°F at rated power) throughout the cycle was justified for Browns Ferry Nuclear Plant Unit 1 in Reference C-3. The operating limit MCPR for FWHOOS is bounded by the operating limit for FFWTR (-54.7°F at rated power).

Power Uprate Operation with power uprated to 3952 MWth was justified for Browns Ferry Nuclear Plant Unit 1 in Reference C-3. Operation with power uprated to 3458 MWth was justified for Browns Ferry Nuclear Plant Units 2 & 3 in Reference C-8; this analysis is also applicable to Browns Ferry Nuclear Plant Unit 1.

Turbine Bypass Valve Out-of-Service (TBVOOS)

Operation with TBVOOS was justified for Browns Ferry Nuclear Plant Unit 1 in References C-3, C-5, and C-7.

Page 188

BROWNS FERRY 1 0000-0044-1520-SRLR Reload 6 Revision 0 EOC Recirculation Pump Trip Out-of-Service (EOC-RPTOOS)

Operation with the EOC RPTOOS was justified for Browns Ferry Nuclear Plant Unit 1 in Reference C-3, C-5, and C-7.

Turbine Bypass and Recirculation Pump Trip Out-of-Service Operation with the combined Turbine Bypass and Recirculation Pump Trip (RPT) Out-of-Service condition was justified in Reference C-7.

Rod Block Monitor (RBM) Considerations The ARTS Rod Withdrawal Error (RWE) analysis validated that the following MCPR values provide the required margin for full withdrawal of any control rod during Browns Ferry Nuclear Plant Unit 1 Cycle 7:

For Power < 90%: MCPR > 1.70 For Power > 90%: MCPR > 1.40 The reported results below are a maximum of the cycle specific and the generic limit for each setpoint.

The RWE OLMCPR values for the 114% and 117% HTSPs are the same as the generic values calculated in Reference C-2 scaled by the change in the Browns Ferry Nuclear Plant Unit 1 Cycle 7 safety limit.

HTSP Reference C-2 Browns Ferry 1 Cycle 7 Without RBM Filter MCPR Limit (based on 1.07 SL) Rated MCPR Limit (based on a 1.09 SL) 107% 1.20 1.32 111% 1.25 1.32 114% 1.30 1.32 117% 1.35 1.38 Filtered setpoints are specified to be lower than unfiltered setpoints due to the additional lag or delay time associated with filtering. The RWE results shown above for the four HTSPs are unblocked for the Cycle 7 specific calculation at 3952 MWth. Thus the results for the filtered signals would remain the same as the lags or delays in the block associated with the filtered signal makes no difference in the results. The RWE results reported above are those calculated at 3952 MWth and they bound the cycle specific calculations performed for Browns Ferry Unit 1 at 3458 MWth.

ARTS Power and Flow Dependent Limits The ARTS power and flow dependent operating limits for all operating flexibility options are provided in Reference C-6.

Page 189

BROWNS FERRY 1 0000-0044-1520-SRLR Reload 6 Revision 0 The Reference C-6 MCPRp limits are calculated for a SLMCPR of 1.09. The Reference C-6 Kp limits are based on a PLU Power Level of 50% rated power.

The Reference C-6 MCPRf limits are calculated for a SLMCPR of 1.09.

The Reference C-6 LHGRFACp limits are based on a PLU Power Level of 50% rated power.

The Reference C-6 LHGRFACf limits remain unchanged from Reference C-2.

SLO Pump Seizure Operating Limit The cycle-independent OLMCPR calculated for a recirculation pump seizure event when operating in Single Loop Operation (SLO) is 1.51. When adjusted for the off-rated power/flow conditions for SLO (i.e., Kp), this limit corresponds to a rated power/flow OLMCPR of 1.35, assuming SLO SLMCPR <

1.11.

To ensure that the SLO pump seizure analysis is bounded for the current operating cycle, Browns Ferry 1 Cycle 7, the rated OLMCPR must be set > 1.35 when operating in SLO.

BROWNS FERRY 1 0000-0044-1520-SRLR Reload 6 Revision 0 Appendix D Thermal Mechanical Compliance A thermal mechanical compliance check is performed for the fast pressurization transients as well as for the loss-of-feedwater heating event and rod withdrawal error to assure that the fuel can operate without violating the thermal mechanical design limits. These limits are established 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. All thermal mechanical limits are met for Browns Ferry 1 Cycle 7.

Operation with VFD was modeled in this reload analysis.
