WebThe second part of the paper addresses aspects of the tritium extraction from the considered coolants. Tritium will be produced in large amounts in the Pb-Li coolant which serves also as tritium breeding material. In the helium or the water coolant, small amounts of tritium may be present, mainly due to permeation processes. http://li.mit.edu/S/14/Paper/Utili17.pdf jerry and mike\u0027s subs near me
