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.
Technical Session|Panel|Sponsored by FCWMD
Monday, November 13, 2023|1:00–2:45PM EST|Fairchild East/West
Session Chair:

Alternate Chairs:

Session Organizer:
The FCWMD has approximately 12 standards maintained by the FWDCC. Many of these standards are endorsed by the NRC and written to support the existing LWR fleet of reactors (e.g., ANS‐57.1‐1992 Design Requirements for LWR Fuel Handling Systems). However, with the significant effort under way to develop and deploy advanced reactor (AR) concepts, many of these standards may either not apply to these AR concepts or require exemptions to be utilized to allow for their application. This panel will discuss the FWDCC maintained standards and identify potential issues and needs to update them to allow for their application to ARs.
