Description
Summary:The IGNITOR tokamak project is one of main directions of scientific collaboration between Russia and Italy. The project is entering the stage of technical design for the location of the machine at the TRINITI site in Troitsk of the Moscow region. The IGNITOR machine differs considerably from other machines based on the tokamak concept by using a super strong magnetic field (13 T) and plasma current (11 MA). It will operate with short pulses (of approximately 10 s in length) and will not have a tritium breeding blanket. The requirements of the tritium fuel cycle are high because three tritium pulses per day are foreseen with a total amount of approximately 10 g to be processed daily. Fuelling will be based on gas injection. It necessary to provide a full tritium processing cycle including the storage and supply of the tritium, plasma exhaust purification, separation of the hydrogen isotopes, detritiation of gaseous and water streams, and tritium recovery from the plasma facing components. This paper considers tritium storage and delivery system as part of the fuel cycle.
