1.         NAME AND TITLE

ART MOD2: Fission Product Migration in Primary System and Containment

2.         CONTRIBUTORS

Japan Atomic Energy Research Institute, Severe Accident Research Laboratory, Department of Reactor Safety Research, Tokai-mura, Naka-gun, Ibaraki-ken, Japan through the OECD Nuclear Energy Agency Data Bank, Issy-les-Moulineaux, France.

3.         CODING LANGUAGE AND COMPUTER

Fortran (P00611PCX8600).

4.         NATURE OF PROBLEM SOLVED

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 radio-nuclides 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 radio-nuclides, 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 into ART MOD2

ART MOD2 was modified in January 2015 to correct coding errors and improve the vibration of the calculation result of water (H2O) vapor.
