NEA report calls for more accurate data on SNF heat decay
The OECD Nuclear Energy Agency has issued a report calling for more-detailed information on tracking the decay heat of spent nuclear fuel from light water reactors. According to the NEA, the report highlights the increasing importance of accurate decay heat estimations due to evolving fuel characteristics, including higher initial fuel enrichment, increased burn-up rates, and extended reactor cycle lengths.
The report, Summary of the NEA Assessment on Spent Nuclear Fuel Decay Heat for Light Water Reactors, summarizes the findings of a subgroup of the NEA’s Working Party on Nuclear Criticality Safety (WPNCS), which ran from January 2022 to January 2024.

Session Organizer:
In order to support the growing demand and sentiments around clean energy generation of all different scaled, nuclear energy technologies will require a true paradigm shift, with shorter deployment timelines, to usher in the next fleet of advanced reactors by 2030 and beyond. This Summer, NEI, in coordination with their members, submitted a comprehensive proposal to the NRC to streamline the regulatory framework for micro-reactors and other larger advanced reactors (light-water and non-light-water) titled, “Regulations of Rapid High-Volume Deployable Reactors in Remote Applications (RHDRA) and Other Advanced Reactors.” The proposal package contains numerous proposed changes to the NRC’s processes, guidance, and regulations for 31 unique regulatory topics, that would achieve a more modern regulatory framework, in response to the ADVANCE Act, and provide a more effective and efficient approach to address the unique considerations for new industrial customers.
