Review of the stack discharge active particle contamination problem

Description: Quantities of the order of ten million to 100 million radioactive particles per month were emitted from the stacks over a period of several months. High activity in the range 0.1 to 3..mu..c was probably confined to large carrier particles of corrosion debris from iron ductwork in the separations plant ventilation air system. This report discusses chemical, physical and radiochemical properties of the particles, and possible biological and health effects of exposure to them. (ACR)

200 Area stack contamination. Interim report, August 2, 1948--October 11, 1948

Description: In connection with the problem of eliminating contamination of the atmosphere by the exhaust from the 221 Building ventilation air stacks, sand filters were previously recommended. Construction of a sand filter in West Area is about completed and construction of a filter in East Area is well underway. This report summarizes the status, technical findings, and comments and suggestions since the writer`s last Interim Report, dated August 6, 1948, was issued.

Process research progress report, April 1--30, 1948

Description: Word was received that the Eimco filter has been shipped from the Salt Lake City plant. It is expected within two weeks or about May 10, 1948. In place of a float gauge referred to in the Process Research Progress Report, March 1--31, 1984, a Uehling Tank-O-Meter will be used on the chemical solution tanks for the W. D. Building. Word was also received that the steam ejector has been shipped. It can be expected within the next few days. This item will complete the equipment to be used for the r… more

Process research progress report, February 16--29, 1948

Description: Treatment of Hot Liquid Waste: Three runs, D-73, D-74, and D-75, were made in the model clariflocculator during this period. In D-73 and D-74 a mixture of hydrolysis supernatant and water was used as the original solution and in D-75 a hydrolysis supernatant, bismuth free activity and water mixture was used as the starting solution. D-73 gave acceptable results, but D-74 and D-75 gave results that were not too satisfactory. It is believed that contamination in the laboratory has effected the re… more

Process research progress report, March 1--31, 1948

Description: Treatment of Hot Liquid Waste: According to the Eimco Corporation, the filter on order in to be shipped the first week of April. Sketches have been prepared giving the general location of the Eimco filter and equipment to be used in testing the unit. No suitable gauge is available for the tanks to be used in the W. D. Building for storing corrosive solutions. A gauge, to be fabricated from polystyrene, has been designed. Treatment of Hot Solid Burnable Waste: Construction of the model incinerat… more
