Tritium storage/delivery and associated cleanup systems for TFTR
The Tritium Storage and Delivery System (TSDS) will provide the tritium for high power plasmas in TFTR. TSDS will store tritium as solid uranium tritide at room temperature. At greater than or equal to 400/sup 0/C gas may be released from uranium and pumped through a metal bellows pump to a holding volume. Acceptably pure T/sub 2/ will be passed along a 40 m manifold into the storage volumes of three piezoelectric gas injection valves above the torus. Tests on several above components are described. Process components are contained within evacuable housings and three seismically qualified gloveboxes. Two of these boxes are serviced by catalytic oxidation/dessicant adsorption-based T/sub 2/ cleanup systems, one of which is dedicated and the other also detritiating torus and neutral beam exhaust gases. TSDS is located in a sealable vault, its air purifiable by a third such system. Emergency dehumidification of the torus test cell and its basement is also provided. TSDS and the cleanup systems will operate remotely under hardwired interlocks and operator-interactive computer control. Interlocks are safety-oriented and, e.g., prevent overheating of uranium, overpressurization of bellows pumps, and large glovebox pressure excursions. Tritium monitors are important to cleanup interlocks.
