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.

The supply of radioactive and stable isotopes is essential for medicine and industry. Medical isotopes are utilized for both therapy and diagnostic imaging. Isotopes are utilized in industry as tracers, for imaging, and for calibration. Stable isotopes play an important role in radioactive isotope production, as environmental tracers, and clinical pharmacology. This panel will examine the current use and necessary supply chain for radioactive and stable isotopes.
