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.

A number of research reactors, test reactors and facilities are in operation or are being developed and built. They support important R&D programs towards current and future developments. Many of these facilities are at university campuses serving as both educational and R&D instruments. While the design space of research facilities is dominated by light water systems, the research capabilities are rapidly expanding towards advanced reactors. This panel will discuss ongoing and planned efforts involving research reactors, test reactors, and research facilities focusing on the significant opportunities offered by these systems in support of advanced reactor R&D.
