The second revision of the V2.0 version has been released to all WP4 partners in December 2011 (after a first revision in March 2011). Besides the account for the feedback of maintenance efforts, the following model evolutions have been included in these revisions:
- Additional improvements of thermal-hydraulics behaviour for swollen water level volumes in primary/secondary circuits,
- Additional improvements of models of corium behaviour in the vessel lower head,
- New user option to manage iodine speciation at primary circuit break (waiting for further improvements on the on-going gas chemistry kinetics developments),
- Improvements of iodine reactions, in particular Ag/I in the sump,
- New improvements of MCCI modelling: first for the EPR core catcher, and also new user option to make easier the selection of adequate thermo-chemistry data as function of the concrete type,
- Modelling improvements on containment phenomena such as hydrogen combustion (flame FRONT model) and dry aerosol resuspension.
A one-week training course for ASTEC beginners was again hosted by IRSN in April 2011 at Cadarache (France). 20 participants coming from 16 Institutes attended this second edition of an ASTEC V2 course which focused of course on the use of the V2.0-rev1-p2 patch version that had been frozen and delivered a few weeks before.
