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.

The MARVEL reactor demonstration is proceeding to deployment with manufacturing underway on long-lead items. This panel will provide a status update on the overall project along with an overview of the TREX-C facility (TREAT Reactor Experiment Cell). A discussion of the safety review for MARVEL, including hazard evaluation will be provided. Additionally an overview of the MARVEL utilization plan will be presented to highlight how MARVEL can be leveraged as a testbed for future users.
