Request for Additional Information Application Dated April 24, 1998 United States Enrichment Corporation Paducah Gaseous Diffusion Plant Docket 70-7001 Please provide the following information:

1. What is the reference code or standard to which the new cranes will be designed, operated, and maintained? The proposed revision to the TSRs only commits to having two hoist brakes that meet the requirements of ANSI B30.2, 1990 edition. The TSR does not address other portions of the standard.

Chapter 1, Appendix A of the Safety Analysis Report only lists portions of the standard which Paducah satisfies, however, there is no clear commitment to the standard. Since two new cranes are being installed, USEC should commit to the entire standard for the new cranes. If USEC is unwilling to commit to the complete standard for the new cranes, please explain why not, providing an explanation for each section/ subsection to which you are not willing to commit.

2. The issue of code commitment in relation to the cranes was originally ,

raised during the review of Amendment 2 on the feed facilities crane design features. During the review, the staff asked USEC to explain why the commitment to the standard was limited to specific portions. Although, USEC did not provide the explanation, the staff deferred resolution of the issue because of the pending Compliance Plan Issue 45 on codes and standards. This compliance Plan issue has yet to be resolved, therefore the staff believes it appropriate to reopen the discussion on code commitment for the existing cranes. Please provide an explanation for each section/ subsection for which USEC is not willing to commit for the existing cranes at the facility.

3. As part of the March 10, 1997, response for additional information on Amendment 2, USEC informed the staff that it was undertaking an initiative to determine if further application of industry codes and standardo at the GDPs was warranted. What is the status of this review?
