Dear Mr. Layton:
DAHER-TLI hereby submits an application for amendment of license USA/9342/AF-96 for Model No. Versa-Pac. All amendment contents have been consolidated to Revision 11 to the Versa-Pac Safety Analysis Report, Docket No. 71-9342.
Revision 11 adds a new criticality analysis to support an increased fissile mass limit for 20wt%
235U enriched material by limiting the total quantity of hydrogenous material in the package for this content limit to 1 lb. Also, an expanded definition of TRISO fuel contents of the package is provided to more clearly describe the permissible contents of this form.

DAHER-TLI is committed to providing timely responses to any proposed questions to support this timing.
