COLR Cycle 32 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for the R.E. Ginna Nuclear Power Plant has been prepared in accordance with the requirements of Technical Specification 5.6.5.
The Technical Specifications affected by this report are listed below:
3.1.1 SHUTDOWN MARGIN (SDM) 3.1.3 MODERATOR TEMPERATURE COEFFICIENT (MTC) 3.1.5 Shutdown Bank Insertion Limit 3.1.6 Control Bank Insertion Limits 3.2.1 Heat Flux Hot Channel Factor (FQ(Z))
3.2.2 Nuclear Enthalpy Rise Hot Channel Factor (FN AH) 3.2.3 AXIAL FLUX DIFFERENCE (AFD) 3.4.1 RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB)
Limits 3.9.1 Boron Concentration R.E. Ginna Nuclear Power Plant COLR-2 Revision 0
COLR Cycle 32 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections. These limits have been developed using the NRC approved methodologies specified in Technical Specification 5.6.5. All items that appear in capitalized type are defined in Technical Specification 1.1, Definitions.
2.1 SHUTDOWN MARGIN' (LCO 3.1.1) 2.1.1 The SHUTDOWN MARGIN in MODE 2 with Keff < 1.0 and MODES 3 and 4 shall be greater than or equal to the limits specified in Figure COLR - 1 for the number of reactor coolant pumps in operation (non main feedwater operation).
2.1.2 The SHUTDOWN MARGIN in MODE 4 when both reactor coolant pumps are not OPERABLE and in operation and in MODE 5 shall be greater than or equal to the one loop operation curve of Figure COLR - 1.
2.1.3 The SHUTDOWN MARGIN required in LCO 3.1.4, LCO 3.1.5, LCO 3.1.6, LCO 3.1.8, and LCO 3.4.5 shall be greater than the limits specified in Figure COLR -
I for the number of reactor coolant pumps in operation and the status of the main feedwater system.
2.2 MODERATOR TEMPERATURE COEFFICIENT 1 (LCO 3.1.3) 2.2.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOL ARO/HZP - MTC shall be less positive than +5.0 pcm/0F for power levels below 70% RTP and less than or equal to 0 pcm/OF for power levels at or above 70% RTP.
The EOL ARO/RTP - MTC shall be less negative than -42.9 pcm/OF.
where:
ARO stands for All Rods Out BOL stands for Beginning of Cycle Life EOL stands for End of Cycle Life HZP stands for Hot Zero Power RTP stands for RATED THERMAL POWER R.E. Ginna Nuclear Power Plant COLR-3 Revision 0
COLR Cycle 32 2.3 Shutdown Bank Insertion Limitl (LCO 3.1.5) 2.3.1 The shutdown bank shall be fully withdrawn which is defined as 2 221 steps.
2.4 Control Bank Insertion Limits1 (LCO 3.1.6) 2.4.1 The control banks shall be limited in physical insertion as shown in Figure COLR-2.
2.4.2 The control banks shall be moved sequentially with a 100 (i 5) step overlap between successive banks.
2.5 Heat Flux Hot Channel Factor (FQ(Z)) 2 (LCO 3.2.1) 2.5.1 FQ(Z) * ((F0) *K(Z) / P) when P > 0.5 FQ(Z) * ((FQ) *K(Z) / 0.5) when P
- 0.5 where:
Z is the height in the core, FQ = 2.45, K(Z) is provided in Figure COLR - 3, and P = THERMAL POWER / RATED THERMAL POWER 2.6 Nuclear Enthalpy Rise Hot Channel Factor (FNH)l (LCO 3.2.2) 2.6.1 F NAH
- FRTPAH * (1 + P FAH * (1-P))
where:
FRTPAH= 1.75, PFAH = 0.3, and P = THERMAL POWER / RATED THERMAL POWER R.E. Ginna Nuclear Power Plant COLR-4 Revision 0
COLR Cycle 32 2.7 AXIAL FLUX DIFFERENCE 3 (LCO 3.2.3) 2.7.1 The AXIAL FLUX DIFFERENCE (AFD) target band is +/- 5%. The actual target bands are provided by Procedure RE-11.1.
2.7.2 The AFD acceptable operation limits are provided in Figure COLR - 4.
2.8 RCS Pressure, Temperature, and Flow Departure from Nucleate Boiling (DNB)
Limits4 (LCO 3.4.1) 2.8.1 The pressurizer pressure shall be 2 2205 psig.
2.8.2 The RCS average temperature shall be
