“…A set of reference accident sequences has been assessed [ 11 for ITER Non-site Specific Safety Report (NSSR-1). Some of those accidents were analysed by the European Union ITER Home Team EU HT, and the relevant results presented in [2]. The updating of the ITER design and the results of the safety analyses performed for NSSR-1 ask for a revision of the reference,accident sequences specification and assessment.…”

The paper presents the environmental source term EST evaluation for two ITER reference accident sequence related to the divertor primary heat transfer system. An exvessel 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.
