実験手順

A calcium nitrate solution 14 from the Calcium Nitrate Reconstitution Station and, as needed, fresh calcium nitrate powder 3 are combined with deionized water 4 obtained from the Deionized Water Supply 2 in a mixing vessel. The resulting calcium nitrate solution 7 and uranyl fluoride solution 1 from the UO2F2 Storage facility are introduced into a precipitator vessel. Tramp and washwater 6 from the Slurry Washer/Dryer, described below, may also be introduced into the Precipitator. The aqueous calcium nitrate reacts with the uranyl fluoride solution to form a slurry 8 of uranyl nitrate and calcium fluoride according to the following stoichiometric relation: UO2F2(aq)+Ca(NO3)2(aq)→UO2(NO3)2(aq)+CaF2(s) The heat of reaction is expected to negligible. The slurry 8 is transferred to a liquid cyclone where the calcium fluoride precipitate is removed. A fraction of the calcium fluoride can be recirculated to function as seed crystals in the Precipitator.
