Tritium Research. Scientists of VNIINM (part of Rosatom) have successfully completed studies on the behavior of tritium in advanced innovative reactor facilities: the molten salt research reactor, the lead-cooled fast neutron reactor BREST-OD-300, as well as research on the development of a tritium complex at the tokamak. This work will solve the problem of accumulation, detection and control of this radioactive hydrogen isotope.
