The cold leg mixing computational fluid dynamics (CFD) – uncertainty quantification (CLM-UQ) benchmark is the fifth benchmark concerning CFD applications to nuclear reactor safety to be organised in the framework of the Nuclear Energy Agency (NEA) Working Group on Accident Management and Analysis (WGAMA).

The main objective of this benchmark is to go a step further in the application of single phase CFD to nuclear safety issues involving mixing problems in the presence of buoyancy effects, like pressurised thermal shocks (PTS).
