1.0 INTRODUCTION
l This report provides the cycle-specific limits for operation of the Cooper Nuclear Station through Cycle 16.
It includes the limits for the Rod Block Monitor Upscale Set Point, Average Planar Linear Heat. Generation Rate (APLHGR), Linear Heat Generation Rate (LHGR), and Minimum Critical Power Ratio (MCPR). If any of these limits are exceeded, the action will be taken as defined in the Technical Specifications.
These core operating limit values have been determined using the l
NRC-approved methodologies given in Revision.10 to Reference 1 and are established such that all applicable limits of the plant safety analysis are met.
2.0 CORE OPERATING LIMITS Cooper Nuclear Station shall be operated within the bounds of the below limits.
The applicable Technical Specifications are referenced in each I
subsection.
2.1 Rod Block Monitor Unseale Setnoint Technical Specifications Table 3.2.C states that the Rod Block Monitor (RBM) upscale (Power Referenced) trip level setting is
.j determined from the following:
Lowest Rated MCPR Limit:
LTSP ITSP HTSP-(LPSP 5 P < IPSP)
(IPSP $ P < HPSP)
(HPSP S P) 2 1.20 5 117.0/125 5 111.2/125 s 107.4/125-2 1.25 5 120.0/125 5 115.2/125 5 110.2/125 2 1.30
$ 123.0/125 5 118.0/125 5 113.2/125 LPSP, IPSP, and HPSP are the power level. setpoints listed on Table 3.2.C.
The lowest rated MCPR limit to be used with this table for Cycle 16 is 2 1.20.
The trip level settings associated with this MCPR limit have been generically calculated and verified to bound the. Rod Withdrawal Error Analysis for Cycle 16 operation.
Technical Specifications
Reference:
3.2.C.
2.2 Average Planar Linear Heat Generation Limits The limiting APMGR value for the mo'st limiting lattice l (excluding.
natural uranium) for each fuel type as a function of Planar Average
'l Exposure and core power and flow is calculated by taking the value j
.from Figure 1, 2, 3, 4, 5, or 6, and multiplying it by the smaller
'i of the-MAP M GR-Flow. Factor, MAPFACy from-Figure 7,
or the
.j Power-Dependent MAPMGR Factor, MAPFAC, from Figure 8.
On Figure 7, use the curve associated with.a maximum. core flow of 102.5 percent, which is the mechanical RRMG scoop tube limit specified in OPLi7.
APMGR values were determined with the SAFE /REFIDOD LOCA methodology j
1 03/26/93 1
t and are given in References 2 and 3, while the MAPFAC and MAPFAC y
p were determined in Reference 6.
i The fuel types referred to in Figures 1, 2, 5, and 6 consists of multiple combinations of enriched uranium and gadolinia called i
lattices with each having its own calculated maximum APMGR (MAPMGR) value.
Hence, these fuel types have multiple MAPLHGR limiting values at a given planar exposure. The MAPMGR values for.
these lattices, along with the axial location of each lattice in the bundle, are considered proprietary information by General Electric and are given in Reference 4 as a function of planar average
{
exposure.
The MAPMGR limits referred to above are for two recirculation loop operations. For single loop operation, the limiting APLHGR value is obtained as explained by the note at the bottom of Pages 5 through i
10.
Technical Specification
Reference:
3.11.A.
}
2.3 Linear Heat Generation Rate Limits
[
These limits are equivalent to the design LHGR, limiting power
[
density, and maximum allowable LHGR referred to in the Technical Specifications. There are different LHGR limits for different fuel types. These limits are given in Table 1.

3.11.B i
2.4 Minimum Critical Power Ratio Limits The operating limit MCPR (OLCPR) values, which are a function of core thermal power, core flow, fuel type, scram time (r), and fuel i
exposure are calculated as follows:
2.4.1 For core thermal power 2 25 percent and < 30 percent of rated power, the OLMCPR is equal to the power dependent MCPR i
(MCPR ) from Figure 8.
p 2.4.2 For core thermal power 2 30 percent of rated power,-the OLMCPR is the greater of either:
i 2.4.2.1 The applicable. flow dependent MCPR (MCPR )
y determined from Figure 10, or l
2.4.2.2 The appropriate scram time (7) dependent MCPR at rated power from Figures 11 through 16, multiplied by the applicable power dependent MCPR l
multiplier (Kp) from Figure 9.
