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.

Alternate Chair:
Richard T. Wood
Major activities in updating standards for digital I&C are occurring worldwide, for both operating reactor upgrades and also SMR and advanced reactor deployment. This panel will focus on the standard updates and new standards and regulations that are being issued to address the multiple regulatory frameworks in the U.S. and around the world. Panelists will represent the standards organizations (ANS, IEEE, IEC) as well as regulators, NEI and international for the range of subjects that are included in these upgrades including Defense-In-Depth and Diversity, Human Factors Engineering and advanced methods of applying risk insights.
