Abstract

The paper presents the environmental source term EST evaluation for two ITER reference accident sequence related to the divertor primary heat transfer system. An ex-vessel LOCA and a pump seizure have been considered as initiating events. The thermal-hydraulic transient analysis and the containment response to the accident have been assessed using the Athena and Intra codes while the Naua Mod 5M code has been considered for aerosol transport to the environment. Ground and stack releases are evaluated, both for tritium and activated materials
