1.2. DESCRIPTION
The Rod Withdrawal Block Monite.- Upscale Instrumentation Trip Setpoint for two recirculation loop operation is determined from the following relationship:
__ (0.65)Wd + 4 3% **
" Clamped, with an allowable value rmt to exceed the allowable value for recirculation loop drive flow (Wd) ui 100%.
Wd is the percent of drive flow required to produce a rated core flow of 98 million Ib/hr. Trip level setting is in percent of rated power (2511 MWth).

Core Operating Limits Report 4.0 MINIMUM CRITICAL POWER RATIO (MCPR) (3.5/4.5) 4.1 TECHNICAL SPECIFICATION
REFERENCE:
Technical Specifications 3.5.K and 3.6.H
4.2 DESCRIPTION
During steady-state operation at rated core flow, the Operating Limit MCPR (OLMCPR) shall be greater than or equal:
1.29 for tave s 0.68 seconds 1.39 for tave 2 0.86 seconds (0. 5 5 7)tave +0.911 for 0.68 < tave < 0.86 seconds where tave -mean 20% scram insertion time for all surveillance data from Technical Specification 4.3.C which has been generated in the current cycle.
For core flows other than rated, these nominal values of OLMCPR shall be increased by a factor of Kf where Kfis as shown in Figure 4-1.
A cycle independent OLMCPR of 1.32 (Option B) was calculated (Reference 5) for operation with a Feedwater Heater Out of-Service (FWHOOS). Therefore, the OLMCPR, calculated using the abovd information, shall be increased by 0.03 whenever operating with a FWHOOS. This event, which conservatively bounds the requirements detailed within the EOD/EOOS document (Reference 5), goes beyond all normal operating conditions in the SRLR (Reference 3).
Q1C14 has been approved for operating up to 15% (Reference 6) above equilibrium coastdown power level with multiple control rods inserted.
At End of Full Power Capability (EFPC) a generic MCPR operating limit MCPR penalty of 0.06 must be added to the operating limit MCPR in order to exceed equilibrium coastdown power.
