Background:
- a. The S-6213 power unit shipping container (PUSC) is used to transport submarine power units (fully assembled and unirradiated cores). The S-6213 PUSC is certified as a Type B package for shipment of fissile and highly radioactive material. Compliance with Title 10, Code of Federal Regulations, Part 71 (10CFR71) is demonstrated through a safety analysis report for packaging (SARP). The S9G power unit in the S-6213 PUSC SARP evaluates the Next Generation Reactor (NGR) and VIRGINIA Forward Fit (VAFF) cores as authorized contents in the S-6213 PUSC.
- b. Reference (a) notified the NRC that a design modification was being pursued for the S-6213 PUSC and that NRC review and concurrence would be requested with the revised SARP incorporating the design modification. Reference (b) requested renewal of NRC Certificate of Compliance (CoC) USA/9186/B(U)F-96 for the S-6213 PUSC, and recommended NRC take action on the renewal request as part of the review of the SARP revision for the S-6213 PUSC design modification.
Discussion:
- a. The Naval Nuclear Propulsion Program has designed and manufactured a new internal pressure cap design for the S-6213 PUSC.

UNCLASSIFIED 2
NR:RR:JHKampen G#C2205956 UNCLASSIFIED PUSC SARP is revised via an Addendum that, together with the SARP, demonstrates compliance with 10CFR71 for the S9G power unit in the S-6213 PUSC package. The Addendum addresses all aspects of the S9G power unit in the S-6213 PUSC package that have changed as a result of the internal pressure cap design change. Enclosure (1) provides a high level summary of the changes presented in the Addendum.
Enclosure (2) provides the full text of the Addendum.
- b. Reference (b) requested renewal of the S-6213 PUSC NRC CoC (USA/9186/B(U)F-96) and removal of NGR and TDC power units as authorized contents because no further shipments of these contents are planned. Naval Reactors requested NRC take action on the renewal as part of this SARP review. Additionally, no shipments of S6W power units are planned and S6W power units are removed as authorized contents from the CoC. The S9G power unit in the S-6213 PUSC package weight is revised because the Addendum calculates a slightly different weight compared to previous analyses. Enclosure (3) contains all CoC changes requested in reference (b) and this letter.
Request for Action: Naval Reactors requests NRC review and concurrence with the S9G Power Unit in the S-6213 PUSC SARP Addendum, Revision Original, provided in Enclosure (2). NRC is requested to renew NRC CoC USA/9186/B(U)F-96, as requested in reference (b), with the changes as documented in Enclosure (3). To support planned shipments of S9G power units to support national security needs for VIRGINIA Class submarine construction, Naval Reactors requests NRC schedule their review to complete by October 2023. Naval Reactors will schedule a review kickoff meeting with the NRC.
