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.
2022 ANS Annual Meeting
Jaime Marian is a professor in the Department of Materials Science & Engineering at UCLA. His group focuses on understanding materials evolution under extreme conditions using multiscale computational modeling, and developing efficient computational techniques, taking advantage of large-scale parallel computing capabilities. Specific areas of interest are microstructural evolution and mechanical property degradation in fusion materials, simulations of plastic deformation in alloys, simulations of thermodynamics and phase transformations in functional materials, strength in nanostructured crystals, and simulations of irradiation damage. He received his PhD in Nuclear Engineering from the Polytechnic University of Madrid, Spain, followed by a Postdoctoral Fellowship at the California Institute of Technology, and a staff scientist position at Lawrence Livermore National Laboratory. He has been the recipient of the DOE Early Career Award and is the author of over 100 publications in the areas of irradiation damage in materials, plasticity, deformation, mechanics, and numerical methods.
