Overview of efforts in the field of fundamental and applied physics with tritium carried out with participation of RFNC-VNIIEF in 2007-2013 is made. New physical results of studying of muon-catalyzed fusion and neutron excess nuclei are presented; project of a new experiment on searching for a magnetic moment of neutrino using a tritium source and helium detector is discussed. Description of a tritium support testbed for a plasma focus-type neutron source with intensity of 1013 s-1is given. Results of studies in the area of interaction of hydrogen isotopes with structural materials are summarized.
