BVPS-1 LICENSING REQUIREMENTS MANUAL 4.1 CORE OPERATING LIMITS REPORT This Core operating Limits Report provides the cycle specific parameter limits developcd in accordance with the NRC approved methodologies specified in Technical Specification Administrative Control 6.9.1.12.
Specification 3.1.3.5 Shutdown Rod Insertion Limits The shutdown rods shall be withdrawn to at least 225 steps.
Specification 3.1.3.6 Control RosLInsertion Limits Control Banks A and B shall be withdrawn to at least 225 steps.
Control Banks C and D shall be limited in physical insertion as shown in Figure 1.
Specification 3.2.1 Axial Flux Difference NOTE:
The target band is 17% about the target flux from 0% to 100% RATED THERMAL POWER.
The indicated Axial Flux Difference:
a.
Above 90% RATED THERMAL POWER shall be maintained within the i7% target band about the target flux difference, b.
Between 50% and 90% RATED THERMAL POWER is within the limits shown on Figure 2.
i c.
Below 50% RATED THERMAL POWER may deviate outside the target band.
