Dear Mr. Denton:

Enclosure 2 to the referenced letter provided a report of the comparison of the finite element method and the lumped mass method of seismic analysis for selected SNUPPS structures. This comparison was provided in response to a request by the NRC's Structural Engineering Branch. The report has recently been updated to include the effects of a dcsign spectrum suggested by Lawrence Livermore National Laboratory for the Wolf Creek site and mod-ifications to the elastic half-space analysis computer code made since the original report. The revised report is attached.

Very ruly yours,
