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.
Radiation Protection and Shielding Division 2024 (RPSD 2024)
Sean Fournier is a nuclear engineer in the Sandia National Laboratories Nuclear Incident Response Program (NIRP). He received his MS in Nuclear Engineering from the University of New Mexico in 2018. Sean started his career in 2010 working in the radiochemistry laboratory at Sandia. Sean has participated in several inter-agency working groups on nuclear incident response preparedness; most notably, the Department of Energy’s Federal Radiological Monitoring and Assessment Center (FRMAC) Laboratory Analysis Working Group. This group is responsible for determining the methods, procedures, and training for sample control and analysis during a national-scale nuclear emergency. Sean is the current skillset leader for the Consequence Management Laboratory Analysis Unit and works toward maintaining readiness of the responders and the technology used by the team.
