Standard No.: GGNS-MS-48.0 Page: 1 of 5 Revision No.: 5 1.0 ' PURPOSE On October 4,1988, the NRC issued Generic Letter 8816 [1] encouraging licensees to remove cycle-specific parameter limits from Technical Specifications and to place these limits in a formal report to be prepared by the licensee. As long as the parameter limits were developed with NRC-approved methodologies, the letter indicated that this would remove unnecessary burdens on licensee and NRC resources.

On October 29,1992, Entergy Operations submitted a Proposed Amendment to the Grand Gulf Operating License requesting changes to the GGNS Technical Specifications to remove certain reactor physics parameter limits that change cach fuel cycle [2]. This amendment committed to placing these operating limits in a separate Core Operating Limits Report (COLR) which h

- defined in Technical Specifications. This PCOL was approved by the NRC by SER dated January 21,1993 [3].

The COLR is controlled via Mechanical Standard GGNS-MS-48.0. This standard is revised accordingly for each fuel cycle or remaining portion of a fuel cycle. Revision 5 of the COLR revises the Cycle 9 core operating limits to include additional LHGR limits.

a

Standard No.: GGNS-MS-48.0

- Page: 2 of_z5-Revision No.: 4 2.0 SCOPE As defined in Technical Specification 1.1, the COLR is the GGNS document that provides the core operating limits for the current fuel cycle. This document is prepared in accordance with Technical Specification 5.6.5 for each reload cycle using NRC-approved analytical methods.

The Cycle 9 core operating lircits included in this report are:

e the Average lha' Linear Heat Generation Rate (APLHGR),

! e the Minimum Cri.ical Power Ratio (MCPR), and e the Linear Heat Generation Rate (LHGR) limit.

l The cycle-specific MCPR safety limits are documented in Technical Specification 2.1.1.2.

', P:ge: 4 of 5 Revision No.: _4 4.0 DEFINITIONS

1. Average Planar Linear Heat Generation Rate (APLHGR) . the APLHGR shall be applicable to a specific planar height and is equal to the sum of the linear heat generation rates for all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle.
2. Average Planar Exposure - the Average Planar Exposure shall be applicable to a specific planar height and is equal to the sum of the exposure of all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle.
3. Critical Power Ratio (CPR) - the ratio of that power in the assembly, which is calculated by application of the fuel vendor's appropriate boiling correlation, to cause some point in l the assembly to experience boiling transition, divided by the actual assembly operating power.
4. Core Operating Limits Report (COLR) - The Grand Gulf Nuclear Station specific i document that provides core operating limits for the current reload cycle in accordance

! with Technical Specification 5.6.5.

5 Linear Heat Generation Rate (LHGR) - the LHGR shall be the heat generation per unit length of fuel rod. It is the integral of the heat flux over the heat transfer area associated with the unit length.

6. Minimum Critical Power Ratio (MCPR) - the MCPR shall be the smallest CPR which exists in the core.
7. MCPR Safety Limit - the minimum value of the CPR at which the fuel could be operated with the expected number of rods in boiling transition not exceeding 0.1% of the fuel rods in the core.

  • e Standard No.: GONS-MS-48.0 Page: 5 of 5 Revision No.: 5 5.0 GENERAL REQUIREMENTS l This section reports the Grand Gulf Cycle 9 core operating limits. As discussed in Technical Specifications 3.2.1,3.2.2, and 3.2.3, these operating limits are applicable when the core thermal power is greater than 25% of rated power.

5.1 Average Planar Linear Heat Generation Rates Consistent with Technical Specification 3.2.1, all APLHGRs for Siemens 9x9-5 bundles shall not exceed the limits reported in Attachment I as a functions of exposure [7]. All APLHGRs for gel 1 lattices shall not exceed the limits reported in Reference 5 as a function of exposure multiplied by the smaller of either the power-dependent or flow dependent MAPI,HGR factors reported in attachment 1 [4]. For each GElI bundle type, Attachment I reports the MAPLHGR for the most limiting lattice at each exposure for reference purposes (4].

5.2 Minimum Critical Power Ratio

Consistent with Technical Specification 3.2.2, the MCPR shall be equal to or greater than the limits reported in Attachment 2 as functions of power, flow, and exposure [4].

5.3 Linear Heat Generation Rate Consistent with Technical Specification 3.2.3, The LHGR for Siemens 9x9-5 bundles shall not l exceed the limits reported in Attachment 3 as a function of exposure as multiplied by the smaller of either the power-dependent or flow-dependent LHGR factors reported in Attachment 3 [4,6].

The LHGR for gel 1 lattices shall not exceed the limits reported in Reference 5 as a function of exposure multiplied by the smaller of either the power-dependent or flow-dependent MAPLHGR factors reported in Attachment 1 [4,5,9].

5.4 Applicability These limits are applicable for operation in the Maximum Extended Operating Domain (MEOD) and with Feedwater Heaters Out of Service - For single-loop operation, the following changes must be performed.

1. The APLHGR for the GElI bundles shall not exceed the MAPLHGR limit as a function of exposure reported in Reference 5 multiplied by 0.83

[4]. The APLHGR for Siemens 9x9-5 bundles shall not exceed the MAPLHGR limit reported in Attachment I multiplied by .86 [4].

2. The MCPR shall be equal to or greater than the limits determined ~in accordance with Section 5.2 above multiplied by the ratio of the single-loop MCPR safety limit to the two-loop MCPR safety limit reported in I

Technical Specification 2.1.1.2 [8].
