The proposed rule would replace prescriptive certification requirements with a more flexible, risk-informed framework that allows applicants to use NRC-endorsed methodologies to demonstrate the safety of transportation packages.
Additionally, the proposal would also update package approval requirements to accommodate larger and more advanced nuclear technologies, helping ensure the regulatory framework keeps pace with innovation across the nuclear fuel cycle.
“America’s next generation of nuclear technologies requires a transportation framework designed for today’s challenges,” said NRC Chairman Ho K. Nieh. “Enabling regulation protects people without slowing down innovation.”
The NRC said the proposed changes would:
- Modernize the package certification process using risk-informed methodologies that support innovative package designs.
- Update package approval requirements to accommodate advanced reactors, new fuel types, and other emerging nuclear technologies.
- Streamline regulatory reviews by providing applicants greater flexibility in demonstrating compliance with NRC safety requirements.
- Eliminate paper reporting requirements by allowing electronic submission of required reports and certification documents.
The proposal is part of the NRC’s broader effort to modernize regulations under Executive Order 14300 and the ADVANCE Act of 2024, ensuring the agency’s regulatory framework reflects modern technologies while maintaining its unwavering commitment to safety.
The NRC will accept public comments on the proposed rule for 30 days following publication in the Federal Register. The agency also plans to hold a public meeting during the comment period to explain the proposal and answer questions.
