Under the guidance of the Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC), the Working Party on Nuclear Criticality Safety (WPNCS) deals with technical and scientific issues relevant to criticality safety.
This report summarises the findings obtained by Subgroup (SG) 16 of the WPNCS, which ran for two years from January 2024 to December 2025. SG-16 was dedicated to defining and running two decay heat benchmarks, to comparing calculated and measured values, and to comparing calculated values between themselves.
