United States Nuclear Regulatory Commission The NRCs Power Reactor Partial Site Release Regulations and Process
- 10 CFR Part 50 - covers licensing of nuclear power reactors
- § 50.82 - Termination of license
- § 50.83 - Release of part of a power reactor facility or site for unrestricted use 7
United States Nuclear Regulatory Commission Power Reactor Partial Site Release 10 CFR 50.83
- Used for unrestricted release of areas before license termination
- Prior written approval from NRC required
- Typically applied to outlying unused areas
- Different requirements for impacted vs non-impacted areas*
- Non-impacted areas - areas with no reasonable potential for residual radioactivity in excess of natural background or fallout levels 8
United States Nuclear Regulatory Commission
§ 50.83 requirements for partial site release (non-impacted areas)
- There is no reduction in the effectiveness of emergency planning or physical security
- Effluent releases remain within license conditions
- Environmental monitoring program and offsite dose calculations are revised to account for the changes
- All other applicable statutory and regulatory requirements continue to be met 9
United States Nuclear Regulatory Commission
§ 50.83 requirements for partial site release (non-impacted areas), contd
- Licensee performs a historical site assessment of the part of the facility or site to be released
- Provide the results of the safety evaluations performed in accordance with § 50.59
- Provide the reasons for concluding that the environmental impacts associated with the proposed release are bounded by previously issued environmental impact statements 1
0
United States Nuclear Regulatory Commission Other NRC requirements for approval of partial site release
- 10 CFR Part 20, Subpart D - Radiation Dose Limits for Individual Members of the Public
- 10 CFR 50.75 - Reporting and recordkeeping for decommissioning planning
- 10 CFR Part 100 - Reactor siting criteria continue to be met 11
United States Nuclear Regulatory Commission NRC actions (non-impacted areas)
- Notice receipt of the release approval request and make the approval request available for public comment
- Conduct a public meeting in the vicinity of the licensee's facility for the purpose of obtaining public comments 12
United States Nuclear Regulatory Commission NRC actions (non-impacted areas) contd
- Determine whether the licensee has adequately evaluated the effect of releasing the property relative to dose, emergency planning, security, environmental, and regulatory requirements
- Determine whether the licensee's classification of any release areas as non-impacted is adequately justified
- Upon determining that the licensee's submittal is adequate, inform the licensee in writing that the release is approved 13
United States Nuclear Regulatory Commission Radiological Surveys
- GEH conducted an environmental site assessment to verify that the properties proposed for release were not impacted by previous operations involving radioactive materials
- A survey was conducted to support release of sites for unrestricted use
- NRC conducted a confirmatory survey to confirm the licensees findings 14
United States Nuclear Regulatory Commission NRC Confirmatory Survey
- Surveys conducted by NRC and ORAU staff, Oak Ridge, TN on behalf of the NRC
- ORAU is NRCs independent contractor with experience, equipment, and trained staff to conduct radiological surveys
- ORAU developed and submitted a proposed sampling plan to NRC prior to onsite inspection )
- The confirmatory survey was conducted the week of February 4th, 2019 and consisted of surface scans and soil sampling.

United States Nuclear Regulatory Commission Forthcoming reports ORAU will send a report to NRC
- Scan survey maps, location of soil samples
- Soil sample results NRC safety evaluation
- Results of ORAU survey
- NRC will draw conclusion about GEHs site assessment The NRC safety evaluation and ORAU report is expected to be issued and will be publicly available with the NRC decision on the requests by the end of August 2019.
