CREEP AND CORROSION RESISTANCE OF NI-ALLOYS IN MOLTEN NAF A LIF SALT
Original language description
The most promising materials for production of ADDT (Acceleration Driver Transmutation Technology) loop components for spent nuclear fuel transmutation are nickel superalloys. The excellent mechanical properties, creep resistance, corrosion resistance inan environment of fused fluoride salt and resistance against radiation embrittlement are required for these alloys. These alloys have to show good technological properties. The creep behaviour and high-temperature corrosion in molten fluoride salts of two experimental nickel alloys (MoNiCr type) and a comparative alloy (Hasteloy B type) have been investigated. The creep tests were performed at temperature 700 °C in stress range from 80 to 160 MPa. The longest times to rupture were achieved for samplesafter forging however the scatter of results was rather higher. Hasteloy B revealed slightly better creep resistance in comparison with alloys of MoNiCr types. The corrosion tests have been performed in a protection nitrogen/hydrogen atmo
