February 10, 2020 MEMORANDUM TO: Christopher Regan, Deputy Director Division of Fuel Management Office of Nuclear Material Safety and Safeguards FROM: Bernard White, Senior Project Manager /RA/

SUMMARY
OF NOVEMBER 14, 2019, MEETING TO DISCUSS THE TN-EAGLE TRANSPORTATION PACKAGE APPLICATION Purpose TN Americas LLC (TN) requested the partially-closed meeting to provide to the U.S. Nuclear Regulatory Commission (NRC) staff an overview of its design and preliminary evaluations for the Model No. TN-Eagle spent fuel transportation package.
Background
On November 14, 2019, a partially-closed meeting was held in Rockville, Maryland, with the NRC staff at the request of TN to discuss TNs design for the TN-Eagle transportation package.
The meeting was noticed on October 25, 2019 (see Agencywide Documents Access and Management System (ADAMS) Accession No. ML19298B001). The list of meeting attendees, including those participating via telephone, is provided as Enclosure 1. The non-proprietary presentation slides are in ADAMS under Accession No. ML19291B709, and the proprietary slides are under Accession No. ML19291B711.
Discussion The TN-Eagle will be a single-forged body surrounded by neutron shielding. The package will be designed to transport bare pressurized-water (PWR) and boiling-water reactor (BWR) spent fuel, and canisters for the Model Nos. NUHOMS EOS-37PTH, and -89BTH (Docket No.
72-1042) storage system. The package is designed to hold up to 37 PWR fuel assemblies or 89 BWR fuel assemblies. The package will employ a double lid system (primary and secondary lids) for containment when transporting bare fuel but will only use the primary lid when transporting spent fuel inside a canister.
CONTACT: Bernard White, NMSS/DFM (301) 415-6577
C. Regan 2 TN provided an overview of the package design and its preliminary evaluations for each technical discipline. TN plans to follow NUREG-2224, Dry Storage and Transportation of High Burnup Spent Nuclear Fuel, for evaluation of high burnup spent fuel. The package would have single or double lid configurations, depending on the content. TN also discussed moderator exclusion and burnup credit for PWR fuel assemblies.
TN provided an overview of its materials, structural, containment, thermal, shielding, and criticality evaluations. TN discussed its fracture toughness calculations and package material properties and how these properties are utilized in the structural evaluation. TN also discussed the results of tests performed on its neutron shield material. TN also provided a description of the impact limiter and discussed the results of static and dynamic tests performed on the impact limiters.
TN discussed how it will demonstrate that the packages containment system will meet the containment criteria in Title 10 of the Code of Federal Regulations 71.51 for both the bare fuel and EOS canister configurations. TN also discussed its structural evaluation for the bare fuel and canister configurations, along with the assumptions that TN will use in evaluating criticality safety and package dose rates, based on the structural evaluation.
TN discussed its thermal analysis methodology and how it plans to evaluate packaging and the spent fuel temperatures for low and high burnup fuel. TN discussed briefly discussed how it will model the spent fuel assemblies, basket assembly, DSC assembly, TN Eagle packaging and impact limiters.
Finally, TN discussed its proposed approach to evaluating criticality safety and maximum dose rates for low and high burnup fuel, and bare fuel and fuel in a canister utilizing methodology in NUREG-2224. The evaluation will consider damage to the package, from the tests for hypothetical accident conditions as appropriate, based on the structural and thermal evaluations.
TN Americas LLC stated that it plans to submit its application in late 2020.
