SEPARATION OF ISOTOPE AND THERMAL DIFFUSION TOWER USED FOR SAID SEPARATION

摘要

PURPOSE:To obtain high safety and high separating efficiency by cooling the cold wall of a thermal diffusion tower with a refrigerant and repeatedly using the refrigerant by a closed system through a refrigerator. CONSTITUTION:Gas contg. isotopes is fed into the space between the peripheral cold wall of a refrigerant jacket 11 and the peripheral warm wall of a heating element 6 through gas inflow/outflow holes 4, 5 and the isotopes are separated. At this time, the warm wall is heated by supplying heat, the cold wall is cooled to ordinary temp. or below with an He refrigerator 15 and the used refrigerant is returned to the refrigerator 15 and used again in a closed cycle. High safety and high separating efficiency can be obtd.
