Removing hydrogen isotopes from gas circuit in nuclear reactor - by diffusion of esp. tritium into heated containers placed in gas stream

摘要

Hydrogen isotopes are removed from the gas phase, esp. tritium is removed from the prim. gas circuit in a high-temp. nuclear reactor, according to the Parent Patent by diffusion into containers placed in the gas stream, whose walls are heated to a temp. optimal for the hydrogen isotopes diffusion. This method is now improved in that the container walls are heated by suitably adjusting the temp. of the prim. gas by branching and re-uniting the gas stream after one part of it is heated e.g. by heat exchange with a steam producing installation. The temp. of the container walls is adequately stabilised by the stabilisation of the prim. gas temp. (the absence of such stabilisation caused fluctuations of the temp. of the container walls heated electrically according to the Parent Patent. The method is economical.
