Laboratory and pilot-plant studies on the conversion of uranyl nitrate hexahydrate to uranium hexafluoride by fluidized-bed processes: Laboratory and pilot-plant studies on the conversion of uranyl nitrate hexahydrate to uranium hexafluoride by fluidized-bed processes. Youngblood, E. L.; Urza, I. J.; Cathers, G. I. (USA). Report, ORNL/TM-5913, 64 pp. Avail. NTIS From: Energy Res. Abstr. 1978, 3(1), Abstr. No. 240 (English) 1977. DOCUMENT TYPE: Report CA Section: 71 (Nuclear Technology) Lab. and pilot-plant studies are described on the conversion of uranyl nitrate hexahydrate (UNH) [13520-83-7] to UF6 [7783-81-5] and on purifn. of the UF6. Exptl. lab. studies on the removal of residual nitrate from UO3 calcine and the fluorination of Tc and subsequent sorption on MgF2 were conducted to support the pilot-plant work. Two engineering-scale pilot plants utilizing fluidized-bed processes were constructed for equipment and process testing of the calcination of UNH to UO3 [1344-58-7] and the direct fluorination of UO3 to UF6.

Aerosols generated by accidents: pressurized liquid release experiments: Aerosols generated by accidents: pressurized liquid release experiments. Sutter, Sue L.; Halverson, Mark A. (Pac. Northwest Lab., Richland, WA 99352, USA). Am. Ind. Hyg. Assoc. J., 45(4), 227-30 (English) 1984. CODEN: AIHAAP. ISSN: 0002-8894. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Mass airborne and particle size distribution of the aerosol generated by the releases of uranine [518-47-8] and uranyl nitrate hexahydrate [13520-83-7] solns. from a pressurized chamber into static air were measured in a series of expts. to investigate the effect of source size and chamber pressure on the airborne release. Chamber pressure is not a significant variable in aerosol generation produced by release of a pressurized liq. Source vol. is not a significant variable when the rupture occurs above the liq. level. All pressurized releases produced a significant fraction of respirable particles. The wt. percent airborne ranged from 4 ′ 10-4 to 0.15% of the source.
