SUBJECT:

Duke Energy Corporation (DEC)

McGuire Nuclear Station Units 1 and 2 Docket Nos. 50-369/50-370 Proposed Technical Specification (TS) Amendments TS 3.7.1S - Spent Fuel Assembly Storage TS 4.3 - Fuel Storage Pursuant to 10 CFR 50.90 and 10 CFR 50.4, thi letter submits a 3 icense amendiaent request (LAR) for the McGuire Nuclear Station Facility Operating Licenses (FOL) and Technical Specifications (TS). This LAR will change the McGuira TS's to provide revised spent fuel pool storage configurations, revised spent fuel pool storage criteria, and revised fuel enrichment and burnup requirements which take credit for soluble boron in maintaining acceptable margins of subcriticality in the spent fuel storage pools. In addition, this LAR will change the McGuire 7S's to provide additional criteria for ensuring acceptable levels of subcriticality in the McGuire spent fuel storage pools. These changes are necessary given the degradation of the spent fuel storage cell Boraflex panels at McGuire. This proposed amendment is applicable to Facility Operating Licenses NPF-9 and NPF-17 for the McGuire Nuclear Station.

Attachmer.t 1 provides marked up pages of the existing McGuire TS's showing the proposed changes. attachment 2 contains the new McGuire TS pages. The Description of Proposed Changes and Technical Justification is provided in Attachment 3. Pursuant to 10CFR50.92, Attschment 4 documents the determination that this proposed amendment contains no significant hazards considerations.

Pursuant to 10CFR51.22 (c) (9) , Attachment 5 provides the basis for the categorical exclusion from performing an Environmental Assessment or Impact Statement. The McGuire Spent Fuel Pool Criticality Analysis, McGuire Spent Fuel Pool Dilution Analysis Summary, and the McGuire Boraflex Degradation Analysis used to support this LAR are shown on Attachments 6, 7, and 8 respectively. Attachments 10 and 11 show the proposed and revised BASES for TS 3.7.14 and 3.7.15.

I L U.S. Nuclear Regulatory Commissi'on.

'i April 5, 1999 Page 2 of 4 Implementation of this amendment to the McGuire FOL's and TS's

will. impact the stations UFSAR. Consequently, upon appro, val of i' this LAR, the applicabl.e revisions will be included in a McGuire UFSAR update. These revisions include a' proposed addition to Chapter 16 of the UFSAR, " Selected Liceasee Commitments" as shown

! in Attachment 9. This commi.tment will provide for periodic j . monitoring of future Boraflex. degradation. If this monitoring determines that the Boraflex in a spent fuel storage pool has

' degraded to levels that would not support the conclusions of the McGuire Cr,i,ticality Analysis that provides a basis for this LAR, then a future LAR would be submitted proposing additional changes to the McGuire TS's as needed to maintain acceptable levels of subcriticality in the McGuire spent fuel storage pools. Note that an evaluation by DEC determined that this Boraflex panel monitoring did not meet the TS criteria specified in 10 CFR 50.36 (c) (2 ) (ii) and as such a new TS is not proposed for this feature.

~

In accordance with Duke internal procedures and the Quality i Assurance Program Topical Report, this proposed amendment has

-been previously reviewed and approved by the McGuire Station's Plant Operations Review Committee and the Duke Corporate Nuclear Safety Review Board. Note that this proposed TS change has been previously discussed with NRC Staff during a January 27, 1999 meeting. During that meeting and in sub3equent docketed correspondence, DEC had committed to submit this LAR by 31 March 1999. However, due to internal reviews, DEC was unable to submit this LAR by that date. Pursuant to 10CFR50.91, a copy of this LAR'is being forwarded to the appropriate North Carolina state officials.

This IJMR includes a new fuel design not currently analyzed.

Consequently, approval of this LAR by July 1, 2000 will allow receipt of this new fuel design for McGuire's Unit 2 Cycle 14

. refueling outage. Timely review will also facilitate removal of administrative controls which are currently being utilized to maintain acceptable margins of suberiticality in the storage pools.

Please contact Julius Bryant at 704-875-4162 with any questions regarding this LAR.
