No. 1821-0537 B'iC12 Core Operating Limits Report Page 7 Revision 1 j SINGLE LOOP OPERATION Brunswick Unit 1, Cycle 12 may operate over the entire MEOD range with Single recirculation Loop Operation (SLO) as permitted by ITS 3.4.1 with applicable limits specified in the COLR for ITS LCO's 3.2.1,3.2.2, and 3.3.1.1. The applicable limits are: LCO 3.2.1 Average Planar Linear Heat Generation Rate (APLHGR) Limits: per Reference 1, the Figuies 9 and 10 described in the APLHGR LIMITS section below include a SLO limitation of 0.8 on the MAPHGR(F) and MAPLHGR(P) multipliers. LCO 3.2.2 Minimum Critical Power Ratio (MCPR) Limits: per Reference 1, the MCPR limits described below and presented in Table I and Figures 11 and 12 apply to SLO { without modification. LCO 3.3.1.1 Reactor Protection System Instrumentation Function 2.b (Average Power Range Monitors Flow Biased Simulated Thermal Power- High) Allowable Value: per Reference 1, these limits - described below under THI EI A STABILITY SOLUTION - apply to SLO without modification. INOPERABLE MAIN TURBINE BYPASS SYSTEM Brunswick Unit 1, Cycle 12 may operate with an inoperable Main Turbine Bypass System in accordance with ITS 3.7.6 with applicable limits specified in the COLR for ITS LCO 3.2.1 and 3.2.2. One bypass valve inoperable renders the System inoperable, although the Turbine Bypass Out-of-Service (TBPOOS) analysis supports operation with all bypass valves inoperable for the l entire MEOD range and up to 110 F rated equivalent feedwater temperature reduction. The system response time assumed by the safety analyses from event initiation to start of bypass valve opening is 0.10 seconds, with 80% bypass flow is achieved in 0.30 seconds. The applicable limits are: I LCO 3.2.1 Average Planar Linear Heat Generation Rate (APLHGR) Limits: in accordance with Reference 1, TBPOOS requires a reduction in the MAPLGHR(P) limits between 25% and 30% power. This reduction is plotted on Figure 10. i LCO 3.2.2 Minimum Critical Power Ratio (MCPR) Limits: in accordance with Reference 1, TBPOOS requires a increase in the MCPR(P) multiplier between 25% and 30% power. This increase is plotted on Figure 12. TBPOOS also requires increased MCPR limits, included in Table 1.

                                             - 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 I through 8. These values were determined with the SAFER /GESTR LOCA methodology described in GESTAR-II (Reference 2). Figures I through 8 are to be used only when hand calculations are required as specified in the bases for ITS 't,2.1 Normal monitoring of the APLHGR limits with POWERPLEX uses the complete set oflattices for each fuel type provided in Reference 3.

The core flow and core power adjustment factors for use in ITS 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 fro.a Figure 10 is used to determine the governing limit. MCPR LIMITS l The ODYN OPTION A, ODYN OPTION B, and non-pressurization tran ient MCPR limits for use in ITS 3.2.2 for each fuel type as a function of cycle average exposure are given in Table 1. These values were detennined with the GEMINI methodology and GEXL-PLUS critical power correlation described in GESTAR-II (Reference 2) and are consistent with the Safety Limit MCPR of 1.09 specified by ITS 2.1.1.2. The core flow and core power adjustment factors for use in ITS 3.2.2 are presented in Figures 11 and 12. For any given flow / power state, the maximum of MCPR(F) determined from Figure 11 and MCPR(P) determined from Figure 12 is used to determine the goveming limit. , i All MCPR limits presented in Table 1, Figure 11 and Figure 12 apply to two-recirculation pump operation and SLO without modification.

l APRM FLOW BIASED SIMULATED THERMAL POWER-HIGH The APRM Flow Biased Simulated Thermal Power-High setpoint as referenced by ITS 3.3.1.1 and TRMS 3.2 is described in the TH1 El A Stability Solution section below. l L_________________.______..__ _

l CP&L Nuclear Fuels Mgrnt. & Safety Analysis Design Calc. No. 1821-0537 B1C12 Core Operating Lirnsts Report Page 9, Revision 1 I APRM CONTROL ROD BLOCK UPSCALE (FLOW BIASED) The APRM Control Rod Block Upscale (Flow Biased) setpoint as referenced in TRMS 3.3 is described in the THI EI A Stability Solution section below. l THI EI A STABILITY SOLUTION Implementation of the THI El A Stability Solution involves exclusion from certain areas of the power / flow map and specific restrictions for operating in other areas. Stability Regions generally protect the high power / low flow regions of the power / flow map and include: an Exclusion Region from which plant operation is excluded by the APRM Flow-biased Scram; a Restricted Region in which operation is restricted to conditions where the Boiling Boundary exists at least four feet above the bottom of the core (Fraction of Core Boiling Boundary or FCBB shall be s 1.0, per ITS 3.2.3); and a Monitored Region in which operation is allowed only if the potential for a developing THI event is monitored by the Period Based Detection System (PBDS operable, per ITS 3.3.1.3). Flow Control Trip Reference (FCTR) cards provide the ITS 3.3.1.1 automatic APRM Flow-biased Scram and the TRMS 3.2 Restricted Region Entry Alarm (RREA) using the TRMS 3.3 Flow-biased Rod Block setpoint. Because the flow signal for these automatic functions is based on drive flow and not core flow, the COLR Flow-biased Scram and Rod Block limits Allowable Values are included as functions of drive flow (Figures 17-20). These curves allow quantification of Technical Specification compliance, once the drive flow input is aligned in accordance with Table 3. However, the Stability Regions defined by these limits as well as the Monitored Region (which is not incorporated into the FCTR card) are analyzed by El A in terms of power versus core flow. Because the plant Operators are accustomed to monitoring plant j condition in terms of core flow, the COLR provides the Stability Regions on the power /(core)  ! flow map for Operations in recognition of human performance factors. Day-to-day and time- I pressured responses by the Operator should use the power / flow map stability regions (Figures 13-16). These Figures define the Monitored and Restricted Regions for compliance with ITS 3.2.3 and 3.3.1.3 and TRMS 3.2. Core flow nominal trip setpoint values on Figures 13-16 correspond to the nominal trip setpoint values translated into drive flow and installed in the FCTR cards. As required by TRMS 3.2, should neither channel of the RREA be operable to protect against unintentional entry into the Restricted Region, the plant must be operated below the flow control line associated with the lowest thermal power in the Restricted Region, or continuous monitoring i of thermal power and core flow maintained by a qualified individual. l l The EI A Stability Solution provides for distinct Flow-biased Scram and Rod Block setpoints for

                                                                " Setup",as well as normal or "non-Setup" conditions (the Monitored Region boundary is unchanged by Setup). "Non-Setup" setpoints (Figures 13,15,17,19) enforce the normal l

Setup setpoints (Figures 14,16,18,20) are to be used only when the FCBB s 1.0, and allow operation in the Restricted Region. When operating in Setup, the Flow-biased Rod Block setpoints generally increase in power to the Flow-biased Scram or power / flow map boundaries. The Flow-biased Scram setpoint generally increases by an equivalent amount (within the power / flow map boundaries) to avoid spurious - scrams from power spikes. The inherent stability from maintaining FCBB less than onejustifies continued operation in the Restricted Region, but not in that portion of the power / flow map

    .which in Setup becomes unprotected by the Flow-biased Scram. The alarm associated with the Rod Block ceases to be a RREA when in Setup, but signals to Operations a similar need to immediately move to a more stable region of the power / flow map.
   ~ The EI A Stability Solution generically provides for distinct Flow-biased Scram and Rod Block
setpoints for recirculation pump SLO and two loop operation. However, for BNP the two loop
   - operation (TLO) Flow-biased Scram and Rod Block setpoints, and TLO Stability Regions, are applicable for SLO without modification (Reference 1).

The EI A Stability Solution provides for distinct Flow-biased Scram and Rod Block setpoints for normal and reduced feedwater temperature conditions (" normal" and " alternate" setpoints) because the core stability decreases with feedwater temperature. Normal setpoints (Figures 13, 14,17,18) are to be used below 30% power or when feedwater temperature is within 50*F rated equivalent of nominal. The alternate setpoints (Figures 15,1619,20) are to be used above 30% rated thermal power when feedwater is reduced by more than 50'F rated equivalent (50*F * (% power /100)") in accordance with IOP-32. For example, a feedwater temperature reduction of 40"F from the design value associated with 50% power would require the attemate setpoints because this reduction would exceed the allowable reduction of 38.3 F, calculated by 50*0.50 * .
