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.
Advances in Nuclear Nonproliferation Technology and Policy Conference (ANTPC 2025)
Plenary Session|Panel
Monday, November 10, 2025|3:15–5:00PM EST|International Ballroom West
Session Organizer:
Dr. Sunil S. Chirayath (ORNL)
For America to truly achieve energy dominance in the global nuclear industry, American products must be exported around the world. To achieve this, such products must meet stringent U.S. and international standards. The Department of Energy’s National Nuclear Security Administration (DOE/NNSA) is responsible for helping U.S. commercial partners facilitate the deployment of U.S. A/SMR technology in a safe, secure, and safeguardable way. Nuclear Nexus is an easy, one-stop-shop for U.S. industry to get support on all things nonproliferation, but what really sits behind this simple portal?
This panel will discuss the broad expertise behind Nuclear Nexus and showcase the support that the NNSA is providing U.S. industry. The DNN participants on this panel represent hundreds of nuclear experts who are addressing complex problems while keeping us safe. This panel will highlight some of their work and summarize how this impressive workforce is supporting U.S. industry.
