Any future European DEMO reactor which is based upon the D-T fusion reaction will require a tritium plant to reprocess gases such that they can be effectively resupplied to the tokamak fueling systems, and to protect the environment and personnel from tritium releases. The plant must also be designed to allow replacement of burnt fuel with tritium and deuterium. This document outlines the preliminary stages of the design of the European DEMO tritium plant, from initial interface and requirements determination, through to identification of required subsystems and proposal of a new tritium plant architecture. It then goes on to cover the review, assessment and selection of potential technologies for each tritium plant subsystem.

Where possible, a proposed technology is put forward. Elsewhere the required further research is identified.
