The ampoule facility for irradiation of structural and absorbing materials in the dissociating coolant N2O4 medium on the Polish reactor ''Mariya''

The ampoule facility is presented, the mode of its operation is described for irradiation of structural and absorbing materials in the medium of dissociating coolant N2O4 applicable to the conditions of material irradiation in the reactor ''Mariya'' (PPR). The faCility is designed for CondUctipg investigations with the following parameters: coolant pressure in the channel up to 16.0 MPa, temperature of sample tests 573-973, the time of investigation up to 5000 h. The facility allows control of the material investigation parameters (temperature, pressure, coolant chemical composition) and heat removal from the materials tested with the help of natural circulation of the cooland in a closed loop of the ampoule channel
