Abstract

PURPOSE: To activate sodium floride and reduce the waste of sodium fluoride by connecting chemical traps packed with sodium fluoride and provided with heaters in parallel to a cold trap.
CONSTITUTION: The uranium hexaflouride and hydrogen fluoride failed to be captured in a cold trap 1 are flowed via valves 3a, 3b into chemical traps 2a, 2b, and are adsorbed by sodium fluoride 8. To regenerate the sodium fluoride 8 of the chemical trap 2a, first the valves 3a, 4a are closed and heaters 9 are operated, then the sodium fluoride 8 is heated. When it attains 100°C, the adsorbed hydrogen fluoride is dissociated 100% and the uranium hexafluoride about 30%. When the temp. of the sodium fluoride rises to 200°C, the remaining uranium hexafluoride is dissociated. The dissociated uranium hexafluoride and hydrogen fluoride are adsorbed by a trap 10.
