This paper outlines the multi-code methodological approach foreseen to estimate the environmental releases of the activated corrosion/erosion products involved in accidents scenarios of a fusion machine. The radioactive releases associated with some Reference Accident Sequences RAS for the Next European Torus NET have been calculated, based on the following items: Radioactive Inventory RI, Process Source Term PST, and Environmental Source Term EST evaluation. The assessment concerns the NET Basic Performance Phase. Various materials (such as AISI 316L, graphite, beryllium, and boron carbide for the PFC, and water as coolant) and operating conditions (normal running and conditioning) are considered. Different codes have been used and compared. The final environmental releases have been obtained by using RELAP5/Mod.3, FUMO, NAUA-Mod.5 M, and ANITA codes.

Abstract
This paper outlines the multi-code methodological approach foreseen to estimate the environmental releases of the activated corrosion/erosion products involved in accidents scenarios of a fusion machine. The radioactive releases associated with some Reference Accident Sequences RAS for the Next European Torus NET have been calculated, based on the following items: Radioactive Inventory RI, Process Source Term PST, and Environmental Source Term EST evaluation. The assessment concerns the NET Basic Performance Phase. Various materials (such as AISI 316L, graphite, beryllium, and boron carbide for the PFC, and water as coolant) and operating conditions (normal running and conditioning) are considered. Different codes have been used and compared. The final environmental releases have been obtained by using RELAP5/Mod.3, FUMO, NAUA-Mod.5 M, and ANITA codes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
