SUBJECT:

CHECK LIST FOR DESIGN ADEQUACY AUDIT In order to complete our raview of your application for an operating license for Waterford Steam Electric Station, Unit 3, the staff must perform a audit of the structural design. We have developed the enclosed check list which you may use as a guide for preparing for the structural audit. This audit is currently scheduled to take place in the New York EBASCO office during the week of April 6,1981.

If you require any clarification, please contact the staff's project manager Suzanne Kebiusek on 492-7119.

Sincerely,
