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 Organizers:
Most advanced reactor designers plan to use high-assay low-enriched uranium (HALEU) fuel, including the two reactors selected by DOE’s Advanced Reactor Demonstration Program. Moreover, some utilities seek to use slightly higher enrichments in existing light-water reactors. However, there is an insufficient supply of HALEU to supply demonstration reactor needs, no domestic HALEU enrichment capability, and significant uncertainty surrounding long-term HALEU demands. To address these challenges, DOE has been down blending high-enriched uranium and has solicited input on a HALEU Availability Program. In addition, several enrichment companies have established HALEU programs. At this panel, panelists from the enrichment industry and government discuss the status and next steps for establishing a domestic HALEU fuel supply chain. Establishing domestic HALEU production capability will enable the US to expand its position in the global nuclear energy market while promoting its own nonproliferation agenda.
