Dust and corrosion product effluents assessment in ITER

A detailed assessment of the activated corrosion products (ACPs) and tokamak dust escaping to the environment during international thermonuclear experimental reactor (ITER) normal operation, including scheduled maintenance, is presented. Calculation models were developed to assess ACPs environmental release through main pathways. The dust air transport to the environment was assessed by the NAUA-Mod.5 code and dedicated computational models. The analysis confirms the conservatism used in non-site specific safety report no.-2 (NSSR-2).
