چکیده :
The amount of tritium created in the blanket cover for each reactive neutron Is called the tritium birth ratio (TBR).Until now, it has not been possible to design a cover with a TBR greater than 1/15. The melting fraction depends on the triple product of Tn .By emitting an electron from the nucleus, tritium undergoes beta decay and becomes a helium-3 nucleus , which has 1 proton and 2 neutrons. There for, tritium is radioactive and the necessary safety precautions must be taken in the fusion reactor. Tritium is removed from the Tokamak in two ways. Either by Vacuum pumps that are pumped towards the deflector or they are dischared through the primary wall and fertile cover, The amount of tritium in fusion is much larger than in fission and there is no experience in large amount of tritium contamination Isotope separation is done by cooling gases to liquid helium temperature and selective heating in four Coupled distillation columns. In addition, the water in the ether facilities and the air in the buildings pass through a purification machine to remove the tritium in them. Heat pumps maintain a Vacuum in the body of the device. These pumps have porous carbon surfaces that are cooled by liquid helium at a temperature of 5k.
