Subject:
McGuire Nuclear Station, Units 1 and 2 Docket Nos. 50-369'and 50-370 Unit 1/ Cycle 7 and Unit'2/ Cycle 6 Core Operating Limits Reports Gentlement By letter dated March 15, 1990 the NRC issued Amendment Nos. 105/87 to Facility Operating Licenses NPF-9 and NPF-17 for McGuire Nuclear Station Units 1 and 2, respectively. These amendments remove certain cycle-specific parameter limits from the Technical Specifications and relocate them to a
" Core Operating Limits Report" (COLR)... Technical Specification 6.9.1._9 as revised by those amendments requires that the COLR. including.any mid-cycle
{
revisions or supplements thereto, shall be.provided upon issuance, for each reload cycle, to the NRC Document Control Desk with copies to the Regional Administrator and Resident Inspector.
Accordingly, pursuant to Technical Specification 6.9.1.9 (and 10 CFR 50.4),
attached are the Core Operating Limits Reports for McGuire. Unit 1/ Cycle 7 and McGuire Unit 2/ Cycle 6.
These reports document the Core Operating l
l Limits which are determined so that all. applicable limits (e.g. fuel 1
thermal-mechanical limits. core thermal-hydraulic limits, ECCS limits, nuclear limits such as shutdown margin, and transient and accident analysis limits) of the Safety Analysis are met. Note that no base load operation-analysis was performed for Unit 1/ Cycle 7 or Unit 2/ Cycle 6, and therefore the axial flu gdifference target band during base load operation, the value for APL, and the W(z) functions for base load operation are not being provided (ref. COLR Sections 2.4 and 2.5). 'In addition, these COLRs L
include revised (via 10 CFR 50.59)' Rod Bank Insertion Limits, as was-previously discussed in my January 17, 1990 COLR License Amendment request-submittal (ref. COLR Sections 2.2 and 2.3).
These are the initial COLRs on McGuire Units 1 and 2, and are being issued / submitted at this time due to the recent License Amendment approval cited above. McGuire Unit 1 is currently in its end-of-cycle 6' refueling outage, with Cycle 7 startup (initial criticality) currently scheduled for May 19, 1990. McGuire Unit 2 is currently operating in Cycle 6, with the 9004240341 900417 l

These reloads are being/will be accomplished under the provisions of 10CFR'50.59.
In the future COLRs will be issued / submitted before cach reload cycle or any remaining part of a reload cycle.
