HATCH NUCLEAR PLANT UNIT 2 BUILDING SEITLD1ENT Gentlenen:

In our subnittal of December 7, 1983, we delineated percentages of total allowable building settlement for Seismic category 1 Structures which have occurred. In further evaluation of the data it has been revealed that there were inaccuracies in the data presented. Also there is disagreement between the FSAR and the Technical Specifications as to the total allowable settlement with the FSAR beirg the more conservative of the two. We are reviewing our building settlement measurements and are conducting an ergineering analysis of the data in the FSAR and the Technical Specifications to determine which is the correct information. Upon completion cf our analysis we will subnit a request for change to the

@ propriate document and amend our subnittal of December 7, 1983, as necessary. The ergineering analysis is scheduled for ccznpletion May 25, 1984.

If you have other questions, please contact this office.
