The core operating limits and setpoints presented in this COLR have been determined using NRC approved methodologies (References 7, 12, 14-32) in accordance with TS 5.6.5.b and are established such that all applicable limits of the plant safety analysis are met in accordance with TS 5.6.5.c.
In addition to the TS required core operating limits and setpoints, this COLR also includes maps showing the allowable power/flow operating range including the Option III stability ranges.
The generation of this COLR is documented in Reference 1 and is based on analysis results documented in References 2, 3, 4 and 5.
Progress Energy Nuclear Fuels Mgmt. and Safety Analysis Design CaIc. No. 2B21-0640 B2C20 Core Operating Limits Report Page 9, Revision 0 APLHGR Limits Steady-state MAPLHGRss limits are provided for AREVA Fuel (Table 20) and GE14 (Tables 21 - 23).
These steady-state MAPLHGRss limits must be modified as follows:
- GE14 MAPLHGR limits have a core power and core flow dependency. GE14 power-dependent MAPFACP multipliers (Table 24) and flow-dependent MAPFACf multipliers (Table 25) must be used to modify the steady-state MAPLHGRss limits (Tables 21 - 23) for off-rated conditions.
- AREVA Fuel MAPLHGR limits do not have a power or flow dependency. However, in order to be consistent with the determination of GE14 MAPLHGR limits, power-dependent MAPFACp multipliers and flow-dependent MAPFACf multipliers with a constant value of 1.0 under all conditions have been assigned to AREVA Fuel.
- GE14 power-dependent MAPFACp multipliers include all allowed EOOS conditions as indicated in Table 24. See COLR section titled "Equipment Out of Service" for a list of analyzed EOOS conditions. Care should be used when selecting the appropriate multiplier set.
- The applied MAPLHGR limit is dependent on the number of recirculation loops in operation.
The steady-state MAPLHGR limit must be modified by a MAPFACsLo multiplier when in SLO.
MAPFACSLo has a fuel design dependency as shown below.
The applied TLO and SLO MAPLHGR limits are determined as follows:
MAPLHGR LimitTLO = MAPLHGRss x (MAPFACp, MAPFACf, 1.0)min MAPLHGR LimitsLo = MAPLHGRss x (MAPFACp, MAPFACf, MAPFACSLO)min where MAPFACsLo = 0.85 for ATRIUM-10 fuel
= 0.80 for ATRIUM 1OXM fuel
= 0.80 for GE14 fuel Linear interpolation should be used to determine intermediate values between the values listed in the tables. Some of the limits tables show two breakpoints at 26.0%P and 50.0%P. IF performing a hand calculation of a limit AND the power is exactly on the breakpoint (i.e. 26.0 or 50.0), THEN select the most restrictive limit associated with the breakpoint.
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 applicable fuel type provided in Reference 5 and as validated in Reference 9.
MCPR Limits The MCPR limits presented in Tables 5 through 11 are based on the TLO SLMCPR listed in Technical Specification 2.1.1.2.
" MCPR limits have a core power and core flow dependency. Power-dependent MCPRp limits are presented in Tables 5 through 10 while flow-dependent MCPRf limits are presented in Table 11.
" Power-dependent MCPRp limits are dependent on CAVEX, SCRAM insertion speed, EOOS, fuel design, number of operating recirculation loops (i.e., TLO or SLO) and core thermal power.
Values for the CAVEX breakpoints are provided in Table 4. See COLR section titled
Progress Energy Nuclear Fuels Mgmt. and Safety Analysis Design Calc. No. 2B21-0640 B2C20 Core Operating Limits Report Page 10, Revision 0 "Equipment Out of Service" for a list of analyzed EOOS conditions. Care should be used when selecting the appropriate limits set.
" The MCPR limits are established such that they bound all pressurization and non-pressurization events.
" The power-dependent MCPRp limits (Tables 5-10) must be adjusted by an adder of 0.02 when in SLO.
The applied TLO and SLO MCPR limits are determined as follows:
MCPR LimitTLO = (MCPRP, MCPRf)max MCPR LimitSLO = (MCPRP + 0.02, MCPRf)max Linear interpolation should be used to determine intermediate values between the values listed in the tables. Some of the limits tables show two breakpoints at 26.0%P and 50.0%P. IF performing a hand calculation of a limit AND the power is exactly on the breakpoint (i.e. 26.0 or 50.0), THEN select the most restrictive limit associated with the breakpoint.
LHGR Limits Steady-state LHGRss limits are provided for AREVA Fuel (Table 12) and GE14 (Table 13). These steady-state LHGRss limits must be modified as follows:
- AREVA Fuel LHGR limits have a core power and core flow dependency. AREVA Fuel power-dependent LHGRFACP multipliers (Tables 14-17) and flow-dependent LHGRFACf multipliers (Tables 18-19) must be used to modify the steady-state LHGRss limits (Table 12) for off-rated conditions.
- AREVA Fuel power-dependent LHGRFACp multipliers are dependent on CAVEX, SCRAM insertion speed, EOOS, fuel design and core thermal power. Values for the CAVEX breakpoints are provided in Table 4. See COLR section titled "Equipment Out of Service" for a list of analyzed EOOS conditions. Care should be used when selecting the appropriate multiplier set.
- The original licensing basis for GE14 LHGR limits did not include a core power and core flow dependency. However, in order to be consistent with the determination of AREVA Fuel LHGR limits, power-dependent LHGRFACP multipliers and flow-dependent LHGRFACf multipliers with a constant value of 1.0 under all conditions have been assigned to GE14.
- GE14 LHGR limits are effectively monitored by GE14 APLHGR limits in accordance with the NRC approved methodology described in Reference 12.
- The applied LHGR limit is not dependent on the number of operating recirculation loops. No adjustment to the LHGR limit is necessary for SLO.
The applied LHGR limit is determined as follows:
LHGR Limit = LHGRss x (LHGRFACp, LHGRFACf)min Linear interpolation should be used to determine intermediate values between the values listed in the tables. Some of the limits tables show two breakpoints at 26.0%P and 50.0%P. IF performing a hand
Progress Energy Nuclear Fuels Mgmt. and Safety Analysis Design Calc. No. 2B21-0640 B2C20 Core Operating Limits Report Page 11, Revision 0 calculation of a limit AND the power is exactly on the breakpoint (i.e. 26.0 or 50.0), THEN select the most restrictive limit associated with the breakpoint.
PBDA Setpoints Brunswick Unit 2 has implemented BWROG Long Term Stability Solution Option III (OPRM) with the methodology described in Reference 6. Plant specific analysis incorporating the Option III hardware is described in Reference 13. Reload validation has been performed in accordance with Reference 7.
The analysis was performed at 100%P assuming a two pump trip (2PT) and at 45%F assuming steady-state (SS) conditions at the highest rod line power (60.5%). The PBDA setpoints are set such that either the least limiting MCPRP limit or the least limiting MCPRf limit will provide adequate protection against violation of the SLMCPR during a postulated reactor instability. Based on the MCPR limits presented in Tables 5 through 11, the required Amplitude Trip Setpoint (1.12) is set by the least limiting 100%P MCPRP limit (1.39) which has an associated Confirmation Count Setpoint (14). The PBDA setpoints shown in Table 3 are valid for any feedwater temperature.
Evaluations by General Electric (GE) have shown that the generic DIVOM curves specified in Reference 7 may not be conservative for current plant operating conditions for plants which have implemented Stability Option I1l. To address this issue, AREVA has performed calculations for the relative change in CPR as a function of the calculated HCOM. These calculations were performed with the RAMONA5-FA code in accordance with Reference 8. This code is a coupled neutronic-thermal-hydraulic three-dimensional transient model for the purpose of determining the relationship between the relative change in ACPR and the HCOM on a plant specific basis. The stability-based OLMCPRs are based upon using the most limiting ACPR calculated for a given oscillation magnitude or the generic value provided in Reference 7.
In cases where the OPRM system is declared inoperable, Backup Stability Protection (BSP) in accordance with Reference 10 is provided. Analyses have been performed to support operation with nominal feedwater temperature conditions and reduced feedwater temperature conditions (FHOOS and FFTR).
The power/flow maps (Figures 1-6) were developed based on Reference 4 to facilitate operation under Stability Option III as implemented by Function 2.f of Table 3.3.1.1-1 and LCO Condition I of Technical Specification 3.3.1.1. All maps illustrate the region of the power/flow map above 25% RTP and below 60% drive flow (correlated to core flow) where the system is required to be enabled. The generation of these maps is documented in Reference 2.
The maps supporting an operable OPRM (Figures 1, 3 and 5) show a Scram Avoidance Region, which is not a licensing requirement but is an operator aid to illustrate where the OPRM system may generate a scram to avoid an instability event. Note that the STP scram and rod block limits are defined in Technical Specifications, the Technical Requirements Manual, and Plant procedures, and are included in the COLR as an operator aid rather than a licensing requirement.
Figures 3 and 4 implement the corrective action for AR-217345 which restricts reactor power to no more than 50% RTP when in SLO with OPRM operable or inoperable. This operator aid is intended to mitigate a spurious OPRM trip signal which could result from APRM noise while operating at high power levels.
Progress Energy Nuclear Fuels Mgmt. and Safety Analysis Design Calc. No. 2B21-0640 B2C20 Core Operating Limits Report Page 12, Revision 0 RBM Setpoints The nominal trip setpoints and allowable values of the control rod withdrawal block instrumentation are presented in Table 1 and were determined to be consistent with the bases of the ARTS program (Reference 11). These setpoints will ensure the power-dependent MCPR limits will provide adequate protection against violation of the SLMCPR during a postulated CRWE event. Reference 3 revised these setpoints to reflect changes associated with the installation of the NUMAC PRNM system. RBM operability requirements, consistent with Notes (a) through (e) of Technical Specification Table 3.3.2.1-1, are provided in Table 2.
Equipment Out-of-Service Brunswick Unit 2, Cycle 20 is analyzed for the following operating conditions with applicable MCPR, APLHGR and LHGR limits.
" Base Case Operation
" SLO
" FHOOS
- Combined TBVOOS and FHOOS Base Case Operation as well as the above-listed EOOS assumes all the items OOS below. These conditions are general analysis assumptions used to ensure conservative analysis results and were not meant to define specific EOOS conditions beyond those already defined in Technical Specifications.
- Any 1 inoperable SRV
- 2 inoperable TBVs (Note that for TBVOOS and TBVOOS/FHOOS all 10 TBVs are assumed inoperable)
- Up to 50% of the LPRMs OOS Please note that during FFTR/Coastdown, FHOOS is included in Base Case Operation and TBVOOS.
Single Loop Operation Brunswick Unit 2, Cycle 20 may operate in SLO over the entire MEOD range with applicable MCPR, APLHGR and LHGR limits. The following must be considered when operating in SLO:
- SLO is not permitted with MSIVOOS.
Various indicators on the Power/Flow Maps are provided not as operating limits but rather as a convenience for the operators. The purposes for some of these indicators are as follows:
" The SLO Entry Rod Line is shown on the TLO maps to avoid regions of instability in the event of a pump trip.
" A maximum core flow line is shown on the SLO maps to avoid vibration problems.
" APRM STP Scram and Rod Block nominal trip setpoint limits are shown at the estimated core
Progress Energy Nuclear Fuels Mgmt. and Safety Analysis Design Calc. No. 2B21-0640 B2C20 Core Operating Limits Report Page 13, Revision 0 flow corresponding to the actual drive flow-based setpoints to indicate where the Operator may encounter these setpoints (See LCO 3.3.1.1, Reactor Protection System Instrumentation Function 2.b: Average Power Range Monitors Simulated Thermal Power - High Allowable Value).
When in SLO, Figures 3 and 4 implement the corrective action for AR-217345 which restricts reactor power to no more than 50% RTP with OPRM operable or inoperable. This operator aid is intended to mitigate a spurious OPRM trip signal which could result from APRM noise while operating at high power levels.
Inoperable Main Turbine Bypass System Brunswick Unit 2, Cycle 20 may operate with an inoperable Main Turbine Bypass System over the entire MEOD range and cycle with applicable APLHGR, MCPR and LHGR limits as specified in the COLR. An operable Main Turbine Bypass System with only two inoperable bypass valves was assumed in the development of the Base Case Operation limits. Base Case Operation is synonymous with TBVINS. The following must be considered when operating with TBVOOS:
- Three or more inoperable bypass valves renders the entire Main Turbine Bypass System inoperable requiring the use of TBVOOS limits. The TBVOOS analysis supports operation with all bypass valves inoperable.
" SLO is not permitted with TBVOOS.
Feedwater Temperature Reduction Brunswick Unit 2, Cycle 20 may operate with RFWT over the entire MEOD range and cycle with applicable APLHGR, MCPR and LHGR limits as specified in the COLR. NFWT is defined as the range of feedwater temperatures from NFWT to NFWT - 10'F. NFWT and its allowable variation were assumed in the development of the Base Case Operation limits. The FHOOS limits and FFTR/Coastdown limits were developed for a maximum feedwater temperature reduction of 11 0.3*F.
The following must be considered when operating with RFWT:
" Although the acronyms FWTR, FHOOS, RFWT and FFTR all involve reduced feedwater temperature, the use of FFTR is reserved for cycle energy extension using reduced feedwater temperature at and beyond a core average exposure of EOCLB using FFTR/Coastdown limits.
- Prior to reaching the EOCLB exposure breakpoint, operation with FWTR >107F and reactor power > 30% RTP requires use of the FHOOS limits. Below 30% RTP, Base Case Operation limits bound FHOOS limits.
- Until a core average exposure of EOCLB is reached, implementation of the FFTR/Coastdown limits is not required even if coastdown begins early.
" When operating with RFWT, the appropriate Stability Option III Power/Flow Maps (Figures 5 and 6) must be used.
" FHOOS operation coincident with TBVOOS is supported using the combined TBVOOS/FHOOS limits.
" SLO is not permitted with RFWT.
