SUMMARY
OF NOVEMBER 20, 2020, MEETING WITH NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (EPID L-2019-PMP-0110)
On November 20, 2020, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) staff and representatives of National Institute of Standards and Technology (NIST) via teleconference. The purpose of this meeting was to discuss the licensing approach with NIST regarding the installation of a liquid deuterium (LD2) cold source for its cold neutron research at the NIST National Bureau of Standards Test Reactor. The NIST is in the process of designing and building an LD2 cold source to replace the current liquid hydrogen (LH2) source. This was the first public meeting related to the installation of the LD2 cold source. The meeting notice and agenda, dated November 3, 2020, is available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML20309A221. NISTs presentation used in the meeting is also available in ADAMS at Accession No. ML20329A526. A list of meeting attendees is provided as an enclosure to this summary.
NIST began the meeting by providing an overview for the use of the LH2 cold source including the description of the LH2 and associate regulatory review process involved in approving the LH2 use at the NIST. NIST also provided a brief analysis on the difference between LH2 and LD2 cold sources and the potential for anticipated accidents. An external expert panel also reviewed NIST LD2 project and it went through the performance calculations, deuterium safety, operation strategy for LH2 and LD2 at different temperatures and pressures and recommended that the NIST specifically evaluate off-site dose from an uncontrolled release of the deuterium inventory with the expected tritium inventory. The presentation also went through the efforts so far that NIST has invested in this LD2 project study, as part of addressing any differences in accident analysis results from the NIST current licensing basis.
Following the presentation, NIST and the NRC staff discussed the potential licensing pathway and schedule for a LD2 cold source license amendment. NIST stated that it could submit a license amendment request (LAR) for the potential use of LD2 cold source by the end of 2020 and is targeting an installation date for the cold source in 2023. The LAR would be a request for a 20.1302, Compliance with dose limits for individual members of the public, paragraph (c) of Title 10 of the Code of Federal Regulations (10 CFR) adjustment to the Part 20 Appendix B Derived Air Concentrations for the tritiated deuterium (DT) gas to enable the Department of Energy methodology, which was based on the International Commission on Radiological Protection (ICRP) 66 and ICRP 66 amends ICRP 30 to include DT inhalation research by Peterman (1985). If the NRC approves the LAR, the rest of the LD2 cold source installation would be conducted under 10 CFR 50.59, Changes, tests and experiments.
At the end of the meeting, NIST and the NRC staff discussed and agreed that, if it would be beneficial for both NIST and the NRC staff, an additional pre-application meeting can be arranged.
