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.

Multiphase thermal-hydraulics, such as boiling flows, plays an important role in nuclear safety and reactor design. However, its understanding, facilitated by both computation and experiment, is still relatively modest as a result of complexities encountered in multiphase modeling and measurement. In this panel session, leading multiphase modelers and experimentalists will join in a discussion to identify current multiphase thermal-hydraulic challenges, and to propose new ideas on how to address those. Specific attention is paid to the synergy between modeling and experiment, and to the role that AI may play in the path forward towards safer and more efficient reactor design.
