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.

In recent years there has been an increased interest in advanced reactors in the United States. Several concepts are being proposed by multiple vendors and start-ups, with an accelerated pathway to market. In particular, DOE has recently issued two awards aimed at deploying demonstration reactors and several more aimed at accelerating current research activities. An important activity related to commercialization of these concepts is licensing and the overall role of the regulator. Furthermore, central to licensing and safety analysis is the understanding of thermal-hydraulics phenomena, which present considerable differences compared to light-water reactors. In this panel we will address current thermal-hydraulic issues in the licensing of advanced reactor concepts and ongoing research on this topic. This panel serves as a follow-up to the previous panel discussion from the 2021 Winter meeting.
