Dear Mr. Case:

Xn response to Mr. Karl Kniel's request or additional information on seismic qualification of safety related electrical and mechanical components, we stated that a more refined seismic analysis for main steam safety valves would be furnished by December 3,

1977.

A copy of this more refined analysis was handed to Ms. M. Mlynczak, NRC Project Manager for D.C. Cook Unit 2 on December 3,

1977 at the ACRS Subcommittee meeting.

This letter formally transmits an additional copy of the above report.

Very truly yours,
