Analysis of tellurium behaviour in the Marviken large scale Aerosol Transport Test with an improved RAFT code version
This report refers to the work carried out in the frame of the project "Modelling the chemical behaviour of tellurium species in the reactor pressure vessel and the reactor cooling system under severe accident conditions". It is related to the validation and improvement work on the tellurium chemistry model in the RAFT code. This involves: (i) the inclusion of new tellurium species in both the gaseous and condensed phases; (ii) the incorporation of a simple model for the interaction of tellurium with silver aerosols; (iii) other minor changes, such as the introduction of new variables to compute separately chemisorption and condensation of Te(2) onto walls, and the detection and correction of some Fortran errors found in the as received version of the code. The validation effort described in this report includes the analysis of the Marviken 4 and 7 experiments with the modified/improved versions of RAFT 1.0 and RAFT 1.1.
