Submittal of the Reload Analysis Report for Unit 1 Cycle 2 Revision

, File:

87-B-056-026 Attached please find revised pages of the Reload Analysis Report (RAR), which contained inaccurate information regarding the upper end fitting hold down plate design.

The proposed design change described in the referenced Reload Analysis Report will not be implemented until after Unit 1 Cycle 2 reload, at which time all fuel fabricated for PVNGS will be modified as described in the referenced RAR.

If you have any questions, please contact W. F. Quinn at (602) 371-4087.

'...- Fuel Oesian With the exception of the design features listed below the mechanical design of the Batch D reload fuel assemblies is identical to the design of the Core 1 Batch C fuel assemblies that were modified to inc&ease the shoulder gap from 1.682 inches to 2 382

inches, Reference 4-1.

No changes in mechanical design bases have occurred since the original fuel design.

The design features incorporated into Batch D were made to improve the fabricability and quality of the fuel and to improve the burnup capability of the poison rods.

The specific changes are discussed in the following paragraphs.

Deleted tw 2.'The inspection envelope for the fuel bundle assembly has been changed, from a square of 8.230 inches per side for all of the bundle with exception of the vicinity around the upper most grid where a square of 8.250 inches per side is permissible to a square of 8.290 inches per side for the entire length of the fuel bundle.

This change will not affect any of the mechanical design considerations from the standpoint of structural behavior and integrity, fuel assembly bow, handling, interface or other considerations.
