Reference:
Certificate of Compliance No. USA /5341/B( )F.
Gentlemen:
The Babcock & Wilcox Company, Naval Nuclear Fuel Division (NNFD) requests that the referenced certificate of compliance be renewed for a period of 18 months.
The enclosed operating procedures and the acceptance tests and maintenance program for the NFP-55 container are provided in support of this request.
NNPD needs the additional time to complete the design and to test the new inner container.
The 18-month period also allows time for the NRC to review and approve an application for licensing the new container for use and for the fabrication of new containers to replace those presently in use.
If ycu need additional information in this regard, please contact me.
Sincerely, Arne F. Olsen i
