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.

Machine-learning models have generated a lot of interest in thermal hydraulics and are starting to penetrate the practice of engineering and design. However, the methods on verification, validation and uncertainty quantification are not routinely applied and the methodology is still in development. The panelists will discuss their experience with ML-based model applications and development and the challenges of V&V and UQ approaches towards ML.
