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.







A report by the OECD Nuclear Energy Agency proposes a new approach to assessing the financial adequacy for undertaking nuclear decontamination and decommissioning projects and high-level radioactive waste management.

Adequate uranium resources exist to support the long-term, sustainable use of nuclear energy for low-carbon electricity generation, as well as for other applications, including hydrogen production. That assessment is contained in the latest (28th) edition of
