Analyses of the thermophoretic Deposition in STORM and TUBA tests using the Fission Product Transport Code SOPHAEROSFunded under: FP6-JRC
In order to validate the mechanistic fission product transport code SOPHAEROS  selected STORM tests (-) as well as TUBA tests TT28 and TT31 were analysed. A detailed description of test facilities and the experimental procedures of the analyzed tests are given. In these separate effect tests the aerosol deposition is caused by thermophoresis. One aim of this study was to investigate whether a general overestimation of deposited mass predicted by the SOPHAEROS code is valid in these separate tests. The main reason was the significant overestimation of the deposited mass in the steam generator obtained in the circuit analyses of the integral PHEBUS FP tests . Different analyses showed that with SOPHAEROS an overestimation by a factor of about approximately 1.5 for the whole circuit (approximately 25 m long piping) and by a factor of approximately 2 in the hot leg of the steam generator (length approximately 4 m) was obtained . Similar results were also predicted with the other commonly used fission product transport codes such as VICTORIA  and RAFT . The final aim, supported by this analysis, is to identify the weaknesses of the models implemented in the fission product transport codes as well as to make suggestions for model improvements. Therefore the results of the TUBA deposition tests TT28 and TT31  as well on mechanical resuspension of the STORM tests SR09 and SR11 calculated with the SOPHAEROS V2.1 module implemented in ASTEC V1.0 are analyzed and discussed.
