SUBJECT:

Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Cycle 29-1 Core Operating Limits Report Pursuant to the requirements of Beaver Valley Power Station, Unit No. 1 Technical Specification 5.6.3, "CORE OPERATING LIMITS REPORT (COLR)," Energy Harbor Nuclear Corp. hereby submits the COLR for Cycle 29. Technical Specification 5.6.3.d requires, in part, that the COLR be provided to the Nuclear Regulatory Commission upon issuance for each reload cycle, including any midcycle revisions or supplements.

The Cycle 29-1 COLR was made effective on October 25, 2022.

The initial Cycle 29 Reload Safety Evaluation (RSE) and COLR were found to be inconsistent with the model files prior to issuance. These inconsistencies are corrected with the Cycle 29-1 revision.

There are no regulatory commitments contained in this submittal. If there are any questions, or if additional information is required, please contact Mr. Phil H. Lashley, Manager - Fleet Licensing, at (330) 696-7208.

Sincerely, John J Digitally signed by John J Grabnar Gra b na r Date: 2022.10.31 o9:o3:o6-o4'oo*

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 (SDM)

a. In MODES 1, 2, 3, and 4, SHUTDOWN MARGIN shall be~ 1.77% ~k/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% ~k/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 ~k/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 bumup 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: MFD is the measured AFD minus the predicted AFD from an incore flux map taken at or near the burn up corresponding to 300 ppm.

and AFD Sensitivity = 0.10 pcm/°F / MFD

      • Predictive Correction is -3 pcm/°F.

(1) The MODE 1 and MODE 2 with kett ~ 1.0 SDM requirements are included to address SDM requirements (e.g., MODE 1 Required Actions to verify SDM) that are not within the applicability of LCO 3.1.1, SHUTDOWN MARGIN (SDM).

COLR Cycle 29-1 Beaver Valley Unit 1 5.1 - 1 LRM Revision 114

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. <2J
b. Control Banks C and D shall be limited in physical insertion as shown in Figure 5.1-2. <2J
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 (Fo(Z))

The Heat Flux Hot Channel Factor- F0 (Z) limit is defined by:

F0 (Z) ~[ c:a} K(Z) for P > o.5 F0 (Z) ~ [CFQ]*K(Z) for P ~ 0.5 0.5 THERMAL POWER Where: CFQ = 2.40 p = RATED THERMAL POWER K(Z) = the function obtained from Figure 5.1-3.

$ 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.

[FXY(Z)Jrurv is the measured planar radial peaking factor and is equal to the value of F~(Z)/PM(z), where pM(z) is the measured core average axial power shape.

The T(Z) values in Tables 5.1-1 and 5.1-2 were generated assuming that they will be used for a full power surveillance, applicable to RAOC Operating Space (ROS) #1 and #2, respectively. The Rj values in Table 5.1-3 and 5.1-4 were generated to account for the increase in Fa between surveillances, applicable to ROS #1 and #2, respectively. The Axv(Z) factors adjust the surveillance to the reference conditions assumed in generating the T(Z) factors. AXY(Z) may be assumed to equal 1.0 or may be determined for specific surveillance conditions using the approved methods listed in TS 5.6.3.

Either ROS1 or ROS2 may be implemented at any time during operation.

If ROS1 is implemented and entering LCO 3.2.1 Condition B for F~ (Z) not within limits, EITHER take Action 8.1.1 and implement ROS2, OR take Action 8.2.1 by using Table 5.1-5 to determine required THERMAL POWER and AFD limits based on Required F~ (Z) margin improvement.

If ROS2 is implemented and entering LCO 3.2.1 Condition B for F~ (Z) not within limits, take Action 8.2.1 by using Table 5.1-5 to determine required THERMAL POWER and AFD limits based on Required F~ (Z) margin improvement.

FfH ~ CF!iH * (1 + PF!iH (1-P))$

Where: CF!iH = Value listed in Table 5.1-6 PF!iH = 0.3 THERMAL POWER p = RATED THERMAL POWER 5.1.8 LCO 3.2.3 Axial Flux Difference (AFD)

The AFD acceptable operation limits for both ROS1 and ROS2 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 FN~H of 1.04, where T is the total number of measured thimbles. At least three measured thimbles per core quadrant are also required.
