Licensing Requirements Manual Core Operating Limits Report 5.1 5.0 ADMINISTRATIVE CONTROLS 5.1 Core Operating Limits Report This Core Operating Limits Report provides the cycle specific parameter limits developed in accordance with the NRC approved methodologies specified in Technical Specification Administrative Control 5.6.3.
5.1 .1 SL 2.1 .1 Reactor Core Safety Limits See Figure 5.1-1 .
5.1.2 SHUTDOWN MARGIN (SOM)
- a. In MODES 1, 2, 3, and 4, SHUTDOWN MARGIN shall be ~ 1.77% Llk/k.(1l
- b. Prior to manually blocking the Low Pressurizer Pressure Safety Injection Signal , the Reactor Coolant System shall be borated to ~ the MODE 5 boron concentration and shall remain ~ this boron concentration at all times when this signal is blocked.
- c. In MODE 5, SHUTDOWN MARGIN shall be ~ 1.0% L'lk/k.
5.1.3 LCO 3.1.3 Moderator Temperature Coefficient (MTC)
- a. Upper Limit - MTC shall be maintained within the acceptable operation limit specified in Technical Specification Figure 3.1.3-1 .
- b. Lower Limit - MTC shall be maintained less negative than - 4.4 x 10-4 L'lk/k/°F at RATED THERMAL POWER
- c. 300 ppm Surveillance Limit: (- 37 pcm/°F)
- d. The revised predicted near-EOL 300 ppm MTC shall be calculated using Figure 5.1-5 and the following algorithm from Reference 11 :
Revised Predicted MTC = Predicted MTC* + AFD Correction** + Predictive Correction***
where,
- Predicted MTC is calculated from Figure 5.1-5 at the burnup corresponding to the measurement of 300 ppm at RTP conditions,
- AFD Correction is the more negative value of :
{O pcm/°F or (MFD
- AFD Sensitivity)}
where: LlAFD is the measured AFD minus the predicted AFD from an incore flux map taken at or near the burnup corresponding to 300 ppm .
and AFD Sensitivity = 0.10 pcm/°F / LlAFD
- Predictive Correction is -3 pcm/°F.
(1) The MODE 1 and MODE 2 with keff ~ 1.0 SOM requirements are included to address SOM requirements (e.g., MODE 1 Required Actions to verify SOM) that are not within the applicability of LCO 3.1.1, SHUTDOWN MARGIN (SOM) .
COLR Cycle 27 Beaver Valley Unit 1 5.1 - 1 LRM Revision 104
Licensing Requirements Manual Core Operating Limits Report 5.1 5.1 Core Operating Limits Report If the revised predicted MTC is less negative than the SR 3.1.3.2 limit (COLR 5.1.3.c) and all of the benchmark data contained in the surveillance procedure are met, then an MTC measurement, in accordance with SR 3.1.3.2, is not required.
- e. 60 ppm Surveillance Limit: (- 42.5 pcm/°F) 5.1.4 LCO 3.1 .5 Shutdown Bank Insertion Limits The Shutdown Banks shall be withdrawn to at least 225 steps.(2l 5.1 .5 LCO 3.1.6 Control Bank Insertion Limits
- a. Control Banks A and B shall be withdrawn to at least 225 steps.(2l
- b. Control Banks C and D shall be limited in physical insertion as shown in Figure 5.1-2.(2)
- c. Sequence Limits - The sequence of withdrawal shall be A, B, C and D bank, in that order.
- d. Overlap Limits( 2l - Overlap shall be such that step 129 on banks A, B, and C corresponds to step 1 on the following bank. When C bank is fully withdrawn, these limits are verified by confirming D bank is withdrawn at least to a position equal to the all-rods-out position minus 128 steps.
5.1 .6 LCO 3.2.1 Heat Flux Hot Channel Factor (Fa(Z))
The Heat Flux Hot Channel Factor - F0 (Z) limit is defined by:
Fa(Z) ::::; [ c;a]
- K(Z) for P > 0.5 F (Z) ::::: [CFQ]
- K(Z) forP ::::: 0.5 Q 0.5 THERMAL POWER Where: CFQ = 2.40 p = RATED THERMAL POWER K(Z) = the function obtained from Figure 5.1-3.
Fg(Z) = F~(Z)
- 1.0815$
F'(j (Z) = Fg (Z)
- W(Z)
(2) As indicated by the group demand counter
$ An additional uncertainty is to be applied if the number of measured thimbles for the moveable incore detector system is less than 75% of the total number of thimbles. If there are less than 75% of the total number of thimbles and at least 50% of the total number of thimbles measured, an additional uncertainty of (0.01 )*(3-T/12.5) is added to the measurement uncertainty, 1.05, where T is the total number of measured thimbles. This adjusted measurement uncertainty is then multiplied by 1.03 to obtain the total uncertainty to be applied. At least three measured thimbles per core quadrant are also required .
COLR Cycle 27 Beaver Valley Unit 1 5.1 - 2 LRM Revision 104
Licensing Requirements Manual Core Operating Limits Report 5.1 5.1 Core Operating Limits Report The W(Z) values are provided in Table 5.1-1 and 5.1-2. The W(Z) v.:1lues in Table 5.1-1 were generated assuming that they will be used for full r, ower surveillance. The W(Z) values in Table 5.1-2 were generated assuming that they will be used for a part power surveillance during initial cycle startup following the refueling outage. When a part power surveillance is performed, the W(Z) values should be multiplied by the factor 1/P, when P > 0.5. When Piss; 0.5, the W(Z) values should be multiplied by the factor 1/(0.5), or 2.0. This is consisrent with the adjustment in the Fa(Z) limit at part power conditions .
The Fa(Z) penalty function , applied when the analytic Fa(Z) function increases from one monthly measurement to the next, is provided in Table 5.1-3.
5.1.7 LCO 3.2.2 Nuclear Enthalpy Rise Hot Channel Factor ( F~H)
F~H ~ CFt,H * (1 + PFt,H (1-P))$
Where: CF t,H = Value listed in Table 5.1-4 PFt,H = 0.3 THERMAL POWER p = RATED THERMAL POWER 5.1.8 LCO 3.2.3 Axial Flux Difference (AFD)
The AFD acceptable operation limits are provided in Figure 5.1-4.

$ An additional uncertainty is to be applied if the number of measured thimbles for the moveable incore detector system is less than 75% of the total number of thimbles. If there are less than 75% of the total number of thimbles and at least 50% of the total number of thimbles measured , an additional uncertainty of (0.01)*(3-T/12.5) is added to the standard uncertainty on FN11H of 1.04, where T is the total number of measured thimbles. At least three measured thimbles per core quadrant are also required.
(1) T' represents the cycle-specific Full Power Tavg value used in core design.
