چکیده

The OECD Nuclear Energy Agency (NEA) Science Committee (NSC) established the Expert Group on Multi-physics Experimental Data, Benchmarks and Validation (EGMPEBV) in 2014 to bridge gap between advanced, multi-physics simulation capabilities relatively low availability of dedicated, high-fidelity experimental data benchmarks specifically for modelling tools. EGMPEBV was mandated establish mechanisms certification benchmark models processes procedures validation oversees three task forces, covering (1) qualification evaluation, (2) guidelines needs (3) example application experiments. These have generated numerous reports surveying state-of-the-art validation, challenge areas recommendations evaluation benchmarks, while parallel developing specifications benchmarks. Three are active development, including a reactivity compensation scenario Rostov Unit 2 VVER-1000, multi-cycle depletion TVA Watts Bar 1 study pellet cladding mechanical interaction within ramp tests performed at Studsvik R2 reactor. We provide an overview recent progress these summary future activities establishing international
