Navigating the Regulatory Waters: Fusion Energy's Evolving Framework

The journey towards establishing a robust regulatory framework for fusion energy systems has witnessed a significant milestone in early 2023. This period observed the release of a crucial document by the US Nuclear Regulatory Commission (NRC) that laid down the foundational stones for regulating fusion energy systems, marking a progressive step in fusion energy's commercial voyage.

Unveiling the 2023 Regulatory Blueprint

On January 3, 2023, the NRC staff submitted a document titled "Options for Licensing and Regulating Fusion Energy Systems" to the Commission. This document delineated three potential regulatory avenues:

Treating fusion systems as utilization facilities and developing a new framework to address the associated specific hazards.

Adopting a byproduct material approach that augments the existing framework outlined in 10 CFR Part 30, titled "Rules of General Applicability to Domestic Licensing of Byproduct Material."

Instituting a hybrid framework, with decision criteria based on the potential risks and hazards posed by a specific fusion system to determine the appropriate regulatory approach1.

Following a thorough examination, the Commission on April 13, 2023, issued a directive approving a limited-scope rulemaking to establish a regulatory framework for fusion systems. This framework is an extension of the NRC's byproduct material framework as outlined in 10 CFR Part 30. The directive also included additional guidelines for the staff, emphasizing:

Consideration of existing licensed fusion systems and those awaiting licensing prior to the rulemaking's completion.

Development of a new volume of "NUREG-1556, Consolidated Guidance About Materials Licenses," dedicated to fusion systems to ensure consistent guidance across the National Materials Program.

Evaluation of necessary controls, such as controls-by-design approaches, export controls, or other relevant controls for near-term fusion systems.

A provision for future scenarios where an anticipated fusion design presents hazards sufficiently beyond those of near-term fusion technologies, mandating staff to notify the Commission and provide recommendations for appropriate action1.

Deliberations and Submissions: A Collaborative Venture

The development of a regulatory framework is a meticulous process that involved comprehensive deliberations. In 2021, the NRC began contemplating options for a regulatory framework for fusion power plants. By early 2023, a report evaluating three regulatory options was submitted to the Commissioners2.
