Description
The problem of Source Term qualification is one of the most important topics in order to predict possible releases of the Activation Products (APs) and tritium from the DEMO Fusion reactor. The prevention of any possible consequence, which can affect the environment and the population, is the mission of Fusion technology. In the frame of the EUROfusion Work Package of Safety Analyses and Environment (WPSAE) a methodology to scale and to evaluate the source term provided by ITER and a Conceptual Study of Commercial Fusion Power Plant (PPCS) sources has been studied.
This paper refers to the activity currently done for the DEMO source terms assessment and the preliminary results obtained in the ongoing activity. During activities in the task, the methodology was developed for prediction of the tritium and APs concentration. The methodology is explained in details useful for prediction of the tritium and APs concentration in Vacuum Vessel (VV) and in the Breeding Blanket (BB) starting from the DEMO current design data and the inventories assumed in ITER, PPCS and SEAFP programs. These results refer to the Helium Cooled Lead Liquid (HCLL) and the Helium Cooled Pebble Bed (HCPB) concepts. This approach is based on the foundations, set in the fission technology safety analysis of the Design Basis Accidents (DBA), Design Extension Conditions (DEC) and Beyond Design Basis Accident (BDBA).
