Abstract: The thermal-hydraulic and physico-chemical code HELIO is developed for numerical simulations and analyses of radiolytic gases (hydrogen and oxygen) accumulation in non-vented steam pipelines of nuclear power plant systems. The HELIO code simulates all relevant process, such as the steam-radiolytic gases mixture convection, the condensate drainage, the buoyancy forces induced by concentration and related gas mixture density differences, the gas mixture and condensate film interfacial shear, the steam condensat…
