Activities and Tasks

The project consists of four types of activities:

  • Scientific management of the code, i.e. implementation of models in the ASTEC code through Fortran 95 programming, overall verification of the integration of the different models: this task will be exclusively performed by the ASTEC code developers, IRSN and GRS;
  • Elaboration and review of general specifications of the code and of the validation matrix: this task will be commonly performed by all partners;
  • Elaboration and review of detailed specifications of the new models, share of knowledge of existing physical models, validation of the code vs. available experiments, and benchmarking by comparison with existing codes: this task will be performed by all partners.
  • Dissemination of knowledge and training of young researchers or students.

Four main domains of associated physical phenomena can be defined: sodium thermal-hydraulics, pin thermo-mechanical behaviour (before and after rupture), source term (i.e. behaviour of fission products after their release from fuel) and neutronics. The detailed modelling work for each of these domains will be organized in four problem-driven sub-WPs. For the sake of simplicity, the containment phenomena will be addressed in the same sub-WP as the evaluation of the source term.

The tasks for each of these four activity types are organized as follows:

  1. Modelling
  2. Integration
  3. Dissemination
