Radioactive contamination in the environs of the Hanford Works for the period January, February, March 1949

Description: This report summarizes in somewhat more detail than the monthly H.I. Environs reports the extent and magnitude of the radioactive contamination detected in the environs of the Hanford Works. Radioactive contamination resulting from the operation of the Hanford Works as well as that found occurring in natural quantities is included. This belated report is being issued merely for the records to serve as a composite summary of measurements already reported in the monthly H.I. Environs reports and … more

Investigation of Flow Coefficient of Circular, Square, and Elliptical Orifices at High Pressure Ratios

Description: Note presenting an experimental investigation conducted to determine the orifice coefficient of a jet directed perpendicularly to an air stream as a function of pressure ratio and jet Reynolds number for circular, square, and elliptical orifices. The effect of air-stream velocity on the jet flow was also determined for three tunnel-air velocities. Results regarding jets discharging into still air and effect of tunnel-air velocity on jet flow.

A preliminary experimental investigation of a submerged cascade inlet

Description: Report presenting an experimental investigation of a submerged air inlet incorporating a cascade of airfoils for turning and diffusing the entering air. Variables associated with submerged air inlets and airfoil-cascade designs were considered, including changes to the ramp plan form and angle for the submerged inlet and the cascade-axis inclination, cascade-blade angle, solidity, and inclination of the center line of the duct for the cascade.

Investigation of the Stack Gas Filtering Requirements and Development of Suitable Filters. Report No. 5

Description: Investigation of dust loading capacity for various assemblies of air filter media on atmospheric dust has continued using the small tester described in previous reports. The effect of fiber size and packing density in Fiberglas mat has been studied. The combination of very fine fibered glass mats now in use at Oak Ridge was given special investigation. Tests were made using a coarser mat as a prefilter and an economic advantage was showm for such protection. As a result of laboratory studies on… more

The Development of Equipment for the Continuous Burning and Leaching of Ground Carbon

Description: Equipment was developed for the continuous burning and leaching of ground carbon in order to recover uranium for the proposed Closed Cycle Beta Process. The burning apparatus consisted of a vertical tube with a grate to support the carbon. An uppdraft of air was used to support combustion. The burning rate of the apparatus was 500 grams of carbon per hour; combustion averaged over 98% complete. The leacher consisted of a heated nitric acid bath divided in four compartments through which ground … more
