UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 MEMORANDUM TO: Cinthya Román, Deputy Director Division of Fuel Management Office of Nuclear Material Safety and Safeguards FROM: Bernard White, Senior Project Manager Storage and Transportation Licensing Branch Division of Fuel Management Office of Nuclear Material Safety and Safeguards

SUMMARY

OF APRIL 30, 2024, MEETING TO DISCUSS AGING MANAGEMENT FOR REVALIDATION OF MODEL NOS.

JMS-87Y-18.5T AND JRC-80Y-20T PACKAGES

Background

By application dated April 3, 2023 (Agencywide Documents Access and Management System Package Accession No. ML23100A181), the U.S. Department of Transportation (DOT) requested the U.S. Nuclear Regulatory Commission (NRC) review the Japanese Certificate of Approval No. J/2044/B(U)F for the Model No. JMS-87Y-18.5T package and recommend whether the DOT should revalidate the Japanese certificate for import and export. On June 14, 2023 (ML23158A141), the NRC issued a request for additional information (RAI) related to the revalidation request. On June 27, 2023 (ML24043A216), August 28, 2023 (ML24023A047 and ML23255A102), September 11, 2023 (ML24022A297), September 14, 2023 (ML24023A031) and March 20, 2024 (ML24046A242), DOT or Edlow International (Edlow) provided a response and supplemental responses to the NRCs RAI on the Model No. JMS-87Y-18.5T package revalidation.

By application dated April 3, 2023 (ML23115A059) the DOT requested NRC review the Japanese Certificate of Approval No. J/2045/B(U)F, dated July 29, 2022, for the Model No.

JRC-80Y-20T package and recommend whether the DOT should revalidate the Japanese certificate for import and export use. On June 14, 2023 (ML23159A001), the NRC issued an RAI related to the package design. On June 27, 2023 (ML24044A118), August 28, 2023 (ML24023A047), September 11, 2023 (ML24022A284, non-public), and March 20, 2024 (ML24046A242), DOT or Edlow provided a response and supplemental responses to the NRCs RAI on the Model No. JRC-80Y-20T package revalidation.

On July 12, 2023 (ML23212B068), the NRC held a conference call with DOT, the Department of Energy, and Edlow to discuss the NRCs RAI and provide more specificity on the type of information the NRC desires in the RAI response.

On April 30, 2024, the NRC held a closed meeting with the DOT and Edlow to discuss the aging management issues raised in the NRCs RAIs on its revalidation recommendation for the Model Nos. JMS-87Y-18.5T and JRC-80Y-20T packages. The meeting was noticed on April 17, 2024 (ML24108A096). The list of meeting attendees is provided as Enclosure 1. There were no presentations used at the meeting.

Discussion

The meeting started with a status of the revalidation request starting with the short-term revalidations that DOT issued for both model Nos. JMS-87Y-18.5T and JRC-80Y-20T package to accommodate shipments since the NRCs remaining questions were on managing aging effects. Both DOT short-term revalidations expire on July 4, 2024. Edlow expressed its desire to complete the current revalidations. The NRC reiterated that all remaining questions are related to evaluation of aging effects. Edlow asked what else, in addition to the information supplied by them, is needed to satisfactorily respond to the NRC questions. The NRC noted that many documents precede 2000 and asked whether there are updated versions.

Each of the materials questions for the Model No. JMS-87Y-18.5T were discussed. In the first materials question, the NRC requested a description of codes and standards or other methods, programs, or procedures that are implemented to ensure package maintenance activities are adequate to manage the effects of aging. As an example, the NRC stated that it needed more granularity in the inspection criteria. Also, the NRC stated that it wants to ensure that the application is clear on what maintenance and inspections are performed and what are their success criteria.

There was discussion on the second materials questions related to depth of information the NRC needs in the response on abrasion. The applicant stated that abrasion didnt occur, however, the NRC is looking for justification of that statement.

The third materials question requested a gap analysis. Edlow stated that the gap analysis is not required since neither of these packages are used for transportation after the storage of spent fuel. The NRC agreed that packages that are not dual-purpose (approved and used for both spent fuel storage and transportation) and therefore, do not need a gap analysis.

The fourth and fifth materials questions are about the wood in the impact limiters. Edlow stated that the temperatures reported for the wood were reported for different locations azimuthally around the package, which is the reason for the discrepancy. Edlow stated that it would ensure that consistent temperatures, as appropriate, are provided in the next RAI supplement. For the response to the fifth materials question on the basis for the wood evaluation. The RAI response did not discuss managing the effects of aging on the wood. The NRC stated that the applicant should ensure that, even though the impact limiters are sealed, they are not gaining water. This could be accomplished by one of a number of methods, such as weighing the limiters or a leak test.

In the sixth materials question, the NRC requested more information related to the maximum temperature for the Boral and its qualified temperature limits. The applicant stated that the C. Román 3

maximum temperatures do not reach temperatures needed to induce aging effects, however that was not clear to staff.

Finally, the discussion briefly mentioned the need to address vibration fatigue, which could be done at another meeting, if the applicant deems it necessary.
