Atlanta, GA 30323 L

Dear Frank:

Upon reviewing the NRC Inspection Manual Procedure 37700, " Design, Design

Changes, and Modifications",

it appears that one goal of the inspection procedure is to evaluate in detail current design modifications, in order to facilitate the inspection you will be conducting during the week of October 15th, I have attached a listing of design modifications which were implemented during the last Unit 1 -refueling outage.

Also attached is a listing of design modifications planned for the 1991 Unit 2 refueling outage with completed design packages on site.

If you will identify to us (prior totheinspection) which design modifications you wish to evaluate, we will ensure that the design paccages are pulled from Document Control and that the design engineer is on site to answer questions.

Please call me as soon as possible so that we can assemble the pachges -

I for your revite and make travel arrangements for the design engineer:,.

Sincerely c

Steve J. Bethay DRM/eb-001164 Attachments cc: J. D. Heidt C. T. Moore NORMS
