SUBJECT:

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY -

ACCEPTANCE OF THE APPLICATION FOR A LICENSE AMENDMENT RE:

REQUEST FOR LICENSE AMENDMENT AND ADJUSTMENT OF TRITIUM EFFLUENT VALUES FOR D2 COLD SOURCE UNDER TITLE 10 OF THE CODE OF FEDERAL REGULATIONS 20.1302(c) (EPID L-2021-LLL-0004)

Dear Dr. Dimeo:

By letter dated December 11, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21053A038), as supplemented by letter(s) dated October 11, 2020, and December 7, 2020 (ADAMS Accession Nos. ML21053A039, and ML21053A040 respectively), the National Institute of Standards and Technology (NIST) applied for an amendment to Facility Operating License No. TR-5 for the National Bureau of Standards Test Reactor.

The license amendment request (LAR) proposes for a new method of evaluation to adequately evaluate the tritium (HT) (and by inference, tritiated deuterium (D2) or DT) dose from a hypothetical release of gaseous DT. Specifically, the NIST requested, in accordance with Title 10 of the Code of Federal Regulations (10 CFR) 20.1302, Compliance with dose limits for individual members of the public, paragraph (c) to adjust the Derived Air Concentration value for HT in Appendix B to 10 CFR Part 20, Standards for Protection against Radiation, and approval for use of the actual chemical characteristics of gaseous DT in using the gaseous HT dose conversion factor adopted by the International Commission on Radiological Protection (ICRP) and published in ICRP Publication 66 (ICRP-66). The ICRP-66 value is to be used to determine an individuals dose and to demonstrate compliance with the occupational dose limit from potential exposure to tritiated water as a result of replacing the current liquid hydrogen source with a new liquid D2 cold source to be installed in 2023.

The U.S. Nuclear Regulatory Commission (NRC) staff performed an acceptance review of the LAR and concluded that it includes sufficient information for the NRC staff to begin its detailed technical review. Our acceptance review has also concluded that, in addition to a license amendment, an exemption in accordance with 10 CFR 20.2301, Applications for exemptions, from the requirements of 10 CFR 20.1201, Occupational dose limits for adults, paragraph (d) and an associated environmental assessment will be completed by the NRC. Notwithstanding the acceptance review, the NRC staff may require additional information to complete the detailed technical review. If needed, the NRC staff will request this information by separate correspondence within approximately 90 days of the date of this letter.

R. Dimeo Based on the acceptance review, the NRC staff expects to complete its review and make a final determination on the LAR by June 30, 2022. This date could change due to several factors, including requests for additional information, unanticipated changes to the scope of the review, unsolicited supplements to the LAR, and others. If the forecasted date changes, the NRC staff will notify you in writing of the new date and an explanation of the reason for the change.

Please reference the above EPID in future correspondence related to this request.

If you have any questions, please contact me at (301) 415-5656, or by electronic mail at Paulette.Torres@nrc.gov.
