SUMMARY
OF NOVEMBER 6, 2020, CATEGORY 2 PUBLIC WORKSHOP ON SPENT FUEL PERFORMANCE MARGINS On November 6, 2020, the U.S. Nuclear Regulatory Commission (NRC) held a Category 2 remote public workshop with the Nuclear Energy Institute (NEI) and other industry representatives to continue dialogue on recommendations contained in the NEIs white paper on Spent Fuel Performance Margins dated November 8, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19318D971). This workshop built upon previous held meetings and workshops including those conducted on January 22, 2020 (ADAMS Accession No. ML20028F277), March 25-26, 2020 (ADAMS Accession No. ML20106F135), April 15-16, 2020 (ADAMS Accession No. ML20126G388), June 11, 2020 (ADAMS Accession No. ML20170A355), June 23 (ADAMS Accession No. ML20197A299), and July 28, 2020 (ADAMS Accession No. ML20223A352), and September 9, 2020 (ADAMS Accession No. ML20262H259), respectively.

SUMMARY
CATEGORY 2 PUBLIC WORKSHOP ON SPENT FUEL PERFORMANCE MARGINS November 6, 2020 On November 6, 2020, the U.S. Nuclear Regulatory Commission (NRC) held a Category 2 remote public workshop with the Nuclear Energy Institute (NEI) and other industry representatives to continue dialogue on recommendations contained in the NEIs white paper on Spent Fuel Performance Margins dated November 8, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19318D971). This workshop built upon previous held meetings and workshops including those conducted on January 22, 2020 (ADAMS Accession No. ML20028F277), March 25-26, 2020 (ADAMS Accession No. ML20106F135), April 15-16, 2020 (ADAMS Accession No. ML20126G388), June 11, 2020 (ADAMS Accession No. ML20170A355), June 23 (ADAMS Accession No. ML20197A299), and July 28, 2020 (ADAMS Accession No. ML20223A352), and September 9, 2020 (ADAMS Accession No. ML20262H259), respectively.
During the November 6, 2020, workshop, the NRC staff, the NEI, and industry representatives held discussions to facilitate better understanding of the new method of evaluation (MOE) approach for meeting 10 CFR Part 72 regulations pertaining to shielding and dose rate. As part of this meeting, the industry provided examples similar to what the NRC staff had provided at the September 9, 2020, workshop.
After the opening remarks by the NRC and the NEI, the industry representatives discussed the information contained in the NEI submittal, Submittal of NEI/Industry-Developed Shielding Method of Evaluation Examples and Introductory Presentation for the November 2020 Table Top Exercise, dated October 15, 2020 (ADAMS Accession No. ML20309A220). Specifically, the NEIs October 12, 2020, submittal provided introductory presentation of industry-developed shielding MOE examples by applying the NRCs new licensing review practices and looking forward to subsequent implementation of these practices.
The two MOE examples as discussed during the workshop were developed by NEIs industry members: Holtec International, and TN Americas, respectively. For both examples, the industry outlined a number of proposed updates relevant to facility documentations, including Final Safety Analysis Report, Technical Specifications, Certificate of Compliance, and other site-specific reports. The industry then gave a presentation regarding its perspective related to the spent fuel performance margin with the new MOE in mind, and described the content of the Core Operations Limits Report pertaining to 10 CFR Part 50, associated applicability to 10 CFR Part 72, and its vision for the cask documentation.
The NRC staff summarized the November 6, 2020, workshop on Spent Fuel Performance Margins by sharing upcoming plans including a meeting being planned between NRC and the industry in December 2020, as well as an anticipated submission of a proposed topical report and a pilot for the proposed amendment, both expected from the industry. The NRC staff shared a summary chart which detailed technical topics related to the NEIs November 8, 2019, white paper, with requested regulatory products, and associated milestones for the NRC and the industry. The staff and industry continued to refine project plans and identify next steps for enhancing spent fuel storage licensing.
Enclosure 3
At the end of the workshop, the NRC staff provided an opportunity for the members of the public to comment or ask questions regarding NRCs regulatory process related to the topics discussed. A member of the public shared a general comment with the NRC staff. The comment expressed did not require follow-up by NRC staff.
More than 50 individuals from industry, vendor groups, public citizens, and NRC staff attended the workshop (some participating in portions only) via WebEx and telephone bridge line. The NRC staff is planning future workshops to continue efforts on the NEI white paper recommendations.
