Objective
The ultimate intention beyond this shared cost action is to provide end-users like utilities, vendors and licensing authorities with a well-validated European Integral Code for the simulation of severe accident sequences in NPPs. The main objective of this proposal is to distribute the integral code ASTEC to European Partners in order to apply the validation strategy issued from the VASA project (4th EC Framework Programme 1994-1998) to ASTEC. Based on this a guidance of numerical modelling and validation will be developed and applied to ASTEC, so that the reliable simulation of severe accident sequences and severe accident management measures will be possible with the code. This will lead to the use of the knowledge gained in 4th EC Framework Programme in the ASTEC development and validation process. The close co-operation of code-developers, validating institutions, and end-users is of special benefit for the proposed work.
Key experiments and severe accidents sequences, which form the basis of analysis, will be selected and defined. Following the risk-oriented approach of the VASA project a guidance for the ASTEC validation process fitting for specific end-user needs as well as for research requirements will be established. The two ASTEC developing organisations have to supply the other project partners with the code. The first release of ASTEC is foreseen for the mid of 2000, the second one of an improved code version for the beginning of 2002. Both of these versions will be made available for all the users on their different platforms. Then the validation process of ASTEC based on the experiments defined before will be performed. The experiments may be taken from the test series PBF-SFD, LOFT, STORM, BETA, HDR, VANAM, PHEBUS and others. Furthermore plant applications with ASTEC for the severe accident sequences defined before, and for the demonstration of the capability for studying accident management measures will be performed. The sequences should be representative for different types of reactors like PWR, BWR, VVER and future concepts like EPR. After the discussion of the results the various European ASTEC users will give their feedback to the developing organisations. Finally the specific users' needs concerning further ASTEC development will be harmonised.
Guidelines for the validation of the integral code ASTEC will be commonly defined and documented by developers, researchers, and end-users. The basis version of ASTEC and an improved one will be available for the partners on different platforms. The extension and quality of the ASTEC validation will be increased considerably. The validation status reached and the needs for further ASTEC development will be defined by the partners with special attention to specific end-users' requirements.
