An introduction to technetium in the gaseous diffusion cascades

Molten Salt Reactor Engineering Study for Off-Gas Management

“…Magnesium fluoride (i.e., MgF 2 ) in the form of porous pellets has been used at large scale for the selective trapping of volatile technetium fluorides and oxyfluorides of technetium mixed with UF 6 (Golliher et al, 1963;Katz, 1964a;Simmons, 1996). Magnesium fluoride is fairly insoluble in water (i.e., 0.0076 g/100 mL at 18°C) (Kohlrausch, 1905), so trapped technetium can be easily removed by washing with water or dilute HNO 3 .…”

Identification of Potential Waste Processing and Waste Form Options for Molten Salt Reactors

“…Magnesium fluoride (i.e., MgF 2 ) has been used at large scale for the selective trapping of volatile technetium fluorides and oxyfluorides of technetium comingled with UF 6 (Golliher et al, 1963;Katz, 1964a;Simmons, 1996). Magnesium fluoride is fairly insoluble in water (i.e., 0.0076 g/100mL at 18°C) (Kohlrausch, 1905).…”
