The Drying System (DYS) provides removal of water from the Tokamak Cooling Water System (TCWS) that cannot be gravity drained and gas baking of divertor cassettes. The DYS should be (a) capable to dry the in-vessel components of the client systems in preparation for periodic leak testing, maintenance or component replacement; (b) able to blow-out (where required) and dry Integrated Blanket/ELM/Divertor (IBED) Primary Heat Transfer System (PHTS) and Vacuum Vessel (VV) PHTS loops to meet operational requirements; (c) able to provide hot nitrogen for gas baking of the divertor cassettes; (d) capable to provide the primary confinement for small amounts of activated corrosion products and tritium during drying operations. Within this system, the Charging Compressor transfers nitrogen from the Nitrogen Gas Distribution System to the nitrogen storage tanks, charges the DYS and client systems.
