By letter dated November 5, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18192B1310), the U.S. Department of Transportation requested that the U.S. Nuclear Regulatory Commission (NRC) staff perform a review of the French Certificate of Approval F/41 O/B(U)-96 Revision Ad, for the Model No. MANON transport package and make a recommendation concerning the revalidation of the package for import and export use. Specifically, you requested that the NRC only review the content in Appendix 3 to the French certificate. The NRC staff performed an acceptance review of your application to determine whether the application contains sufficient technical information in scope and depth to allow the NRC staff to complete a detailed technical review per the International Atomic Energy Agency Specific Safety Requirements No. 6, Regulations for the Safe Transport of Radioactive Material, 2012 Edition. | |||
This letter is to advise you that based on our acceptance review, the application does not contain sufficient technical information. The information needed to begin our review is described in the enclosed request for supplemental information. In order to start our technical review, this information should be provided within 2 weeks from the date of this letter. Upon receiving your responses to this request for supplemental information, the NRC staff will evaluate the information to determine whether the supplementary information is responsive to the NRC staffs concerns. | |||
The staff is available for a public meeting if you wish to discuss these issues in more detail prior to deciding on your course of action. Please reference Docket No. 71-3094 and EPID L-2018-NEW-0010 in future correspondence related to this action. | |||

The staff needs this information to verify whether the MANON package meets the International Atomic Agencys Specific Safety Requirements No. SSR-6, Regulations for the Safe Transport of Radioactive Material 2012 Edition, requirements relating to allowable maximum radiation levels in paragraphs 526, 527, 648(b), 659(b)(i).
