SUMMARY

L

_ This report provides the values of. the AVERACE PLANAR LINEAR HEAT CENERATION RATE (APLHCR) limits, the Kg core flow adjustment-factor, cand the MINIMUM CRITICAL POWER RATIO (MCPR) limits for Brunswick Unit 1, Cycle 7.as required.by Technical Specification 6.9.3.1.

Per Technical Specifications'6.9.3.2 and 6.9.3.3, these values-have been determined using NRC-approved methodology and are established such that-all applicable limits of the plant safety analysis are met.

i Preparation of this report was performed in accordance with CP&L Nuclear Fuel Section Quality Assurance requirements and is documented in Reference 1.

APLHCR LIMITS The limiting APLHCR value for the most limiting lattice'(excluding.

natural uranium) of each fuel type as a function of AVERACE PLANAR EXPOSURE is given in Figures 1,2,3, 4, and 5.

These values were determined with the SAFE /REFLOOD LOCA methodology described in CESTAR-II (Reference 2).

Figures 1,2,3, 4, and 5 are used when hand calculations are required as-specified in Technical Specification 3.2.1.

MCPR LIMITS The ODYN OPTION A, ODYN OPTION B, and non pressurization transient MCPR limits'for use in Technical Specifications 3.2.3.1 and 3.2.3.2 for each fuel type as'a function of cycle average exposure are given in Table 1.

These values were determined with the CEMINI methodology and CEXL-PLUS critical powe. ratio correlation described in CESTAR-II (Reference 2) and are consistent with a Safety Limit MCPR of 1.04.

The Kg core flow adjustment factor for use in Technical Specification 3.2.3.1 is given in Figure 6.
