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 Organizer:
The MARVEL reactor is well on its way to become the first Department of Energy (DOE) advanced reactor demonstration in several decades. After completing the 90% final design, the MARVEL projected shifted focus to submitting the safety basis for the reactor to DOE, fabrication and testing of several key components (e.g., guard vessel, reactor control system), and the utilization strategy for the reactor. The panel will provide an overview of the current status of the demonstration project with an emphasis on these aforementioned topics.
