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.
Plenary Session
Monday, December 11, 2023|8:00–9:00AM CST|Galerie 3
Nuclear energy has been substantially enabled by the presence of materials that can withstand the harsh temperature and radiation temperature environments associated with the production of nuclear power. As we look forward to the future role of nuclear energy, the deployment of higher temperature reactors, higher radiation environments associated with fast spectrum and fusion reactors, and waste forms for advanced reactors will require continued advances in materials research to address these opportunities and challenges. ARPA-E has funded some materials research and this talk will highlight future needs, as well as some previously funded efforts.
