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.

Panelists will present the experimental capabilities of test facilities that can be used to support the development of new reactor concepts and designs. These facilities will have the ability to generate high-quality data that can be used for system and computational fluid dynamic code validation. Such data can support safety analyses and reduce uncertainty, especially for thermal hydraulic phenomena of interest, enhance our technical understanding, and fill in technical gaps. The panelists will also provide information on the current status and on future testing that is being planned. The presentations include: Thermal Hydraulic Testing Facilities for Lead Fast Reactor Development; Developing Nuclear Technology through Design-Build-Test; High Pressure/High Temperature Helium Flow Test Facility at City College of New York; and Combined Positron Emission Particle Tracking/CT Experimental Capabilities for Nuclear Engineering Applications.
