Tritium inventory considerations in fusion reactors. Topical report

The feasibility of controlled thermonuclear fusion has yet to be proven. However, early attempts at a safety analysis of proposed plant designs can point out possible accident situations which can then be considered in future development programs. Tritium which will be present in early concern with regard to the exposure of the public to a radioactive material. Before any attempt can be made to ascertain the danger to the public of either steady state releases of tritium to the environment or of releases associated with a plant accident, it is necessary to determine the magnitude of the tritium inventory. This work presents a model which will allow for the determination of this inventory based on system operating parameters. A parametric study is also presented to show how system residence times and reactor operating parameters effect the plant inventory
