Abstract
In the scenery of next coming fusion facilities as ITER and DEMOthe environmental impact of systems managing large (kg) tritium amount represents a public scrutiny issue. Furthermore, potentially new dose limits imposed by International Commission on Radiological Protection (ICRP) shall impact the overall costs of fusion technology deployment and the next coming devices designs . Refined environmental tritium dose impact assessment schemes are then overwhelming. Detailed assessments can be procured from the knowledge of the real boundary conditions of the primary tritium discharge phase into atmosphere (and into soils). Lagrangiandispersion models using real-time meteorological and topographic data provide different meteorological scenarios (and consequently plume over Mediterranean Sea, or as consequence of midjornwind, plume over Interior of Iberian Peninsula) and further strong tuning . Advance simulation tools are under development looking for effective refinement. The tool integrates modeled numerical records (analysis and forecast fields) from European Centre for Medium range Weather Forecast (ECMWF) with a lagrangianatmospheric dispersion model (FLEXPART). These model outputs can be coupled with tritium dose secondary phase pathway assessment tools. Nominal tritium discharge operational reference and selected incidental ITER-like plant systems tritium form source terms have been assumed. The real-time daily data and mesh-refined records together with lagrangiandispersion model approach provide accurate results for doses to population by inhalation or ingestion in the secondary phase.
