A AREVA Ref AFS-18-0010 January 30, 2018 ATTN: Document Control Desk Director, Spent Fuel Project Office Office of Nuclear Material Safety and Safeguards U. S. Nuclear Regulatory Commission Washington, DC 20555-0001
SUBJECT:
BRRPackageAmendmentRequest,DocketNo. 71-9341, SARRevision 11 AREVA Federal Services LLC (AFS) hereby submits Revision 11 of the Safety Analysis Report for the BRR Package, Docket No. 71-9341. This revision adds the transport ofCo-60 isotope production targets to the authorized payloads.
The Co-60 is generated at reactors such as the ATR in Idaho, and shipped to users in the BRR package.
A new basket has been designed to accommodate the targets, and target holders have been designed to house each target to confine any material that could escape from a target. In addition, a personnel barrier has been designed for use with the isotope payloads, to maintain the accessible surface temperature within regulatory limits. No changes have been made to the cask or impact limiters.
Structural, thermal, and shielding analyses (reflected in revisions to SAR chapters 2, 3, and 5, respectively) have been updated. All regulatory requirements have been met and and all margins of safety remain positive. Necessary changes to SAR chapters 1 and 7 have been made to accommodate the isotope payloads. Chapters 4, 6, and 8 remain unchanged from Revision 10. All changes are indicated by a revision bar in the right page margin. Due to the quantity of changed pages, and due to the fact that paper copies are now double-sided, the SAR is updated in its entirety, and all pages are identified as Revision 11. A brief SAR change summary table is provided below.
AFS would also like. to request a correction of a typographical error we discovered in the Certificate of Compliance (CoC), Revision 5, issued by the NRC on July 21, 2016. In Table 1.4 of the CoC, for TRlGA Fuel ID 201, the fuel OD should be corrected from 1.44 inches to 1.41 inches, consistent with the dimension given in* Table 1.2-1 of the BRR package SAR. Of note, this discrepancy has nQ saf~ty consequences.
As was discussed during our initial phone call in late October, an expedited NRC review of this SAR revision is requested by the Department of Energy Office of Science Isotope Programs customer, with the goal to have the CoC issued by early October, approximately 8 months from now. This expedited review is needed to support the current schedule for shipping the initial Co-60 irradiated targets in November 2018 in order to fulfill contracted deliveries of medical devices and isotopes, and to utilize a small window of availability for using the single BRR cask. The DOE Isotope Programs customer and AFS will provide prompt responses to any questions or requests for additional information to support the expedited review.
Included with this letter is one paper copy of the SAR and one CD-R containing the PDF file "BRRC SAR, Complete, Rev. 11.pdf' (48,049 kb, 777 pages). The CD is contained within an envelope labeled, "BRR Package, Docket 71-9341.SAR Revision 11, Electronic Copy of Document".
