Strategy for Environmentally and Socially Attractive Fusion Tritium System

Some strategic considerations for fusion energy to be deployed in the future as environmentally and socially attractive option are presented from safety and resource aspects. With the environmental and biological behavior of tritium being understood, not only emission control by technological approach, controlling impacts on public health and social acceptability also became more important. Safety feature of the fusion plant that exhausts small amount of tritium in normal operation based on active control of emission leads to possible better scenario for reduced impacts. Selection of the coolant and possible emergency procedure will have impact on accidental scenario. Fuel resource issue is another major feature that affects attractiveness. Self sufficiency of tritium and deuterium in the total plant system was considered in relation with the operation scenario and development strategy.
