The BOL/ARO/HZP-MTC shall be less positive than +0.7 x 10-4 'k/k/qF for power levels up to 70% RTP with a linear ramp to 0 'k/k/qF at 100% RTP.
The EOL/ARO/RTP-MTC shall be less negative than -5.35 x 10-4 'k/k/qF. 1 2.3.2 The MTC Surveillance limits are:
The 300 ppm/ARO/RTP-MTC should be less negative than or equal to
-4.60 x 10-4 'k/k/qF. 1 The revised predicted near-EOL 300 ppm MTC shall be calculated using Figure 6 and the following algorithm:
Revised Predicted MTC = Predicted MTC* + AFD Correction** + Predictive Correction***
where,
- Predicted MTC is calculated from Figure 6 at the burnup corresponding to the measurement of 300 ppm at RTP conditions,
- AFD Correction is the more negative value of:

CORE OPERATING LIMITS REPORT, VEGP UNIT 1 CYCLE 23 MARCH 2020 Table 1 FQ(Z) PENALTY FACTOR Burnup Penalty (MWD/MTU) Factor 9941 1.0200 10158 1.0215 10376 1.0215 10593 1.0209 10811 1.0200 Notes:
The Penalty Factor, to be applied to FQ(Z) in accordance with SR 3.2.1.2, is the maximum factor by which FQ(Z) is expected to increase over a 39 EFPD interval (QRPLQDOsurveillance interval of 31 EFPD plusthe maximum allowable extension not to exceed 25% of the surveillance interval per SR 3.0.2) starting from the burnup at which the FQ(Z) was determined.
Linear interpolation is adequate for intermediate cycle burnups.
For all cycle burnups outside the range of the table, a penalty factor of 1.0200 shall be used.

Fully withdrawn shall be the condition where control rods are at a position within the interval t 225 and d 231 steps withdrawn.
NOTE: The Rod Bank Insertion Limits are based on the control bank withdrawal sequence A, B, C, D and a control bank tip-to-tip distance of 115 steps.
