A facility is described that allows safe handling of high tritium gas activ
ity as dozens kilocuries in a regular laboratory environment. It is used to
make and deliver into the target a mixture of specific isotopic compositio
n with the contamination requirement of 10(-7) v.f. for Z>1 elements, and r
ecover it upon completion of operation. With this facility, efforts have be
en accomplished to investigate into the muon catalyzed fusion on two target
s - liquid tritium and high-pressure tritium types. Also, the operation ran
ge was 0.1-120 MPa for pressure and 20-800 K for temperature and the amount
of tritium used was about 100 kCi. The facility showed reliability in oper
ation without indications of radiation beyond the safety level.
