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 fuelling 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…


Functional materials’ properties are influenced by microstructures which can be changed during manufacturing. Experimental characterisation is often time consuming and expensive. A technique is presented which digitises graphite foam via X-ray tomography and converts it into image-based models to determine properties in silico. By simulating a la…

The aim of the Exhaust Detritiation System (EDS) of the JET Active Gas Handling System (AGHS) is to convert all Q-based species (Q2, Q-hydrocarbons) into Q2O (Q being indifferently H, D or T) which is then trapped on molecular sieve beds (MSB). Regenerating the saturated MSBs leads to the production of tritiated water which is stored in Briggs drum…

Analytical results of a complete JET cryopump regeneration, including the nitrogen panel, follow- ing the first ITER-Like Wall campaign are presented along with the in-situ analyses of residual gas. H/D mixtures and impurities such as nitrogen and neon were injected during plasma operation in the vessel to study radiation cooling in the scrape-off-…
