This publication by the International Atomic Energy Agency (IAEA) presents the results of a coordinated research project focused on benchmarking computational tools for fuel burnup and material activation against experimental data in research reactors. Conducted from 2015 to 2020, the project aimed to enhance the knowledge and expertise of member states in numerical analysis to improve the design, operation, utilization, and safety of research reactors. It involved research groups from 11 member states and developed benchmarks for nine different research reactors. The study included multicycle core depletion analysis and experiments on sample activation and structural material activation. The publication provides insights into the benchmark modelling approaches, computer codes used, and the effects of these tools, with supplementary files available online. This work serves as a resource for the research reactor community to validate and refine analytical tools for reactor safety and performance. |
