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.

Thank you for participating in the 20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20)!
The Proceedings of NURETH-20 are now available to all who registered for the conference. Access to the Proceedings is linked to the account you used to register for the meeting.
You can also access the Proceedings by logging in to the ANS website and then:
Click Subscriber Access from the left-hand navigation bar to be taken to the publication platform, epubs.
On the epubs platform, click Proceedings from the navigation bar.
On the next page, the NURETH-20 Proceedings will be available.
NURETH is the premier gathering for experts in nuclear reactor thermal hydraulics and related topical areas. This meeting is held every two years. The Washington DC ANS Section is pleased to host NURETH-20 in Washington, DC, USA. Washington, DC is more than the capital of the USA– it is the center of both support and regulation of the nuclear industry. Washington DC is not only a center of government but also a tremendous visitor center with cultural attractions for all.
All exhibitors will also be acknowledged on the ANS website, at the Opening Plenary and on signage displayed throughout the meeting. Exhibitors also have the option to have their name placed on promotional items.
