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 RPD
Tuesday, November 14, 2023|1:00–2:45PM EST|Lincoln East
Session Chair:
Abdalla Abou-Jaoude (INL)
Session Organizer:
Alternate Chair:
Massimiliano Fratoni (UC Berkeley)
The Department of Energy (DOE) granted demonstration and risk reduction awards to multiple U.S. companies via the Advanced Reactor Demonstration Program (ARDP). This panel will discuss technical updates from vendors pursuing reactor demonstrations such as Natrium, Xe-100, Hermes, and the Molten Chloride Reactor Experiment (MCRE). The panel will primarily focus on the technical design challenges of the reactor systems and recent progress in demonstration efforts.
