The Benchmark for Uncertainty Analysis in Best-Estimate Modelling (UAM) for Design, Operation and Safety Analysis of Light Water Reactors (LWRs) is an international high-visibility benchmark for uncertainty analysis in best-estimate coupled code calculations for design, operation, and safety analysis of LWRs.
The annual workshops are attended by many experts in industry, research institutes, national laboratories, academia, and government agencies. Benchmark activities have the the oversight of the Expert Group on Uncertainty Analysis in Modelling (EGUAM), which reports to the Working Party on Scientific issues of Reactor Systems (WPRS) at the Nuclear Science Committee (NSC), OECD/NEA. Since it addresses multiscale/multi-physics aspects of uncertainty analysis, it works in close co-ordination with the benchmark groups on coupled neutronics/thermal-hydraulics simulations and on coupled core-plant problems. The Expert Group also coordinates its activities with the Working Group on Analysis and Management of Accidents (WGAMA) of the Committee on the Safety of Nuclear Installations (CSNI). The Expert Group provides advice to the WPRS and the nuclear community on the scientific development needs (data and methods, validation experiments, scenario studies) of sensitivity and uncertainty methodology for modelling of different reactor systems and scenarios.
