Evaluation of the radionuclide concentrations in soil and plants from the 1975 terrestrial survey of Bikini and Eneu Islands

Description: In June 1975 a radiological survey was conducted of the terrestrial environment of Bikini and Eneu islands (Bikini Atoll) to evaluate the potential radiation dose to the returning Bikini population. In this report, we present measurements of the radionuclide concentration in soil profiles and in dominant species of edible and nonedible, indicator plants. The use of these data to derive relationships to predict the plant uptake of radionuclides from soil is described. Approximately 620 soil and … more

Three-dimensional temperature history of a multipass filled weldment. Part 2. [HEATINGS]

Description: Computer simulation of the three-dimensional temperature history in a multipass filled weldment was attempted by modifying a transient heat transfer code, HEATING5. The model includes temperature-dependent physical parameters, radiation and convection heat losses, turbulent and laminar convection in the molten pool, and variable arc velocity, intensity, and weld geometry. The model requires approximately 28 CPU min to simulate one second of welding. 15 figures, 8 tables.

Report on the reconnaissance resistivity survey in the East Mesa area, Imperial County, California for U. S. Department of the Interior, Bureau of Reclamation

Description: A section of notes on geothermal exploration using the resistivity method precedes the main body of the paper. Field data from the Broadlands Area of New Zealand, Java, and the Imperial Valley, California are included. The reconnaissance resistivity survey recently completed in the East Mesa Area confirmed that a broad zone of low resistivities at depth extends through the area in a NNW direction. The interpretation of the resistivity data and the location of the resistivity lows at depth is mu… more

Properties of Kel F-800 polymer

Description: Kel F-800 fluorocarbon polymer has been selected as the binder for the TATB explosive in the B77 bomb. Kel F-800 is a 3M copolymer derived from the monomers chlorotrifluorethylene (CTFE) and vinylidine fluoride (VF/sub 2/). To understand and define Kel F-800 in relation to its intended use, as well as to generate guidelines for controlling the WR material, a thorough evaluation of its properties and the expected variations from different production lots was made. The research showed that Kel F-… more

Thermal analysis of LOFT containment vessel penetrations S-5E and S-6A

Description: Thermal analysis of the LOFT containment vessel penetration S-6A was conducted for steady-state operation and blowdown transients. Penetration S-6A is a 20-inch pipe through which passes a 10-inch pipe from the steam generator containing 600/sup 0/F steam. Recommendations for penetration S-5E were based on the analysis of penetration S-6A. Penetration S-5E is an 18-inch pipe through which pass a 4-inch pipe containing the steam generator feedwater at 430/sup 0/F and a 0.5-inch pipe containing s… more

Analysis of stirred-tank carbonation reactors. [Removal of /sup 14/CO/sub 2/ by reaction with Ca(OH)/sub 2/]

Description: The removal of CO/sub 2/ from air in a calcium hydroxide slurry-agitated reactor was investigated to aid the design of such vessels. Gas-liquid interfacial areas were calculated using theoretical rate expression and experimental data at specific operating conditions. A correlation for interfacial areas was then determined as a function of impeller speed, impeller diameter, gas flow rate, and concentration of the slurry. Decontamination factors were also determined.
