From the letter: "We strongly encourage the commission to identify actions to accelerate the development of this technology-inclusive regulatory framework prior to the statutory deadline. Advanced nuclear reactors are expected to be smaller, safer, and more efficient. Some even hold the promise of re using spent nuclear fuel. We expect the NRC’s regulatory framework will account for the innovative features of advanced nuclear technologies. We also expect the NRC’s rulemaking to establish the rules to license and regulate these advanced nuclear technologies in a predictable, efficient, and affordable manner. This will help nuclear innovators successfully deploy advanced nuclear technologies with enhanced performance and reduced risk.”
Rulemaking status: The commission is currently reviewing the NRC staff’s proposed rulemaking plan, titled “Risk-Informed, Technology-Inclusive Regulatory Framework for Advanced Reactors.” The plan proposes to publish the final rule in August 2027, but in the senators’ view, this date could fail to provide adequate time to comply with NEIMA’s statutory deadline in the event that the NRC encounters unexpected delays. “NEIMA’s statutory deadline is intended to serve as a backstop, not a target completion date,” the senators write. “The proposed rulemaking plan acknowledges staff may find opportunities and efficiencies that could support earlier completion of the rulemaking. Setting high expectations for an aggressive schedule will more likely result in the realization of those efficiencies.”
Background: NEIMA authorizes appropriations through fiscal year 2024 to complete the rulemaking. To date, Congress has appropriated nearly $40 million, including $15 million in FY 2020, to develop the rule.
