3. DESCRIPTION OF PROGRAM OR FUNCTION
ART Mod2 aims at a comprehensive analysis for the FP behaviour in primary system and in containment during severe accidents and therefore the code considers the removal of radionuclides of up to 60 materials including chemical compounds by natural deposition and by the engineered safety features (ESF) such as spray systems. As for the natural deposition of radionuclides, the code can consider the phenomena such as gravitational settling, thermophoresis, diffusiophoresis, Brownian diffusion, diffusion under laminar or turbulent flows, resuspension, condensation, chemisorption and revaporization. The code also models the aerosol growth by agglomeration of aerosols and condensation/ evaporation of volatile material at the aerosol surface. Recently, the models for iodine chemistry in containment sump water was incorporated.

7. UNUSUAL FEATURES
ART Mod2 has a fast running capability to cover various accident sequences in a Probabilistic Safety Assessment (PSA). Since the code is a module of JAERI's integrated severe accident analysis code, THALES-2, the improvement of ART can be directly reflected on the source term analysis with THALES-2.
