Input and decayed values of radioactive liquid wastes discharged to the ground in the 200 Areas through 1975

Description: Low and intermediate level liquid wastes from chemical separations processing of spent reactor fuel elements have been discharged to the ground in the 200-Areas since 1944. Large volumes of process cooling water, normally free of radioactive contaminants, are discharged to surface ditches or natural surface depressions (ponds). Lesser volumes of liquid waste such as steam condensates, process condensates, scavenged process waste supernatants, and plutonium processing wastes have been, or are be… more

Acoustic emission from beryllium

Description: The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensi… more

Regional transport model of atmospheric sulfates

Description: A regional transport model of atmospheric sulfates was developed. This quasi-Lagrangian three-dimensional grid numerical model uses a detailed SO/sub 2/ emission inventory of major anthropogenic sources in the eastern U.S. region and observed meteorological data during an episode as inputs. The model accounts for advective transport and turbulent diffusion of the pollutants. The chemical transformation of SO/sub 2/ and SO/sub 4//sup 2 -/ and the deposition of the species at the earth's surface … more

Geochemistry and hydrothermal alteration at selected Utah hot springs. Final report: Volume 3 (revised)

Description: Application of Na-K-Ca geothermometry to warm springs in Utah indicates several areas with sufficiently high apparent temperatures to be of interest as geothermal exploration targets. A zone of warm springs in the Bonneville Basin show Na-K-Ca temperatures from 150/sup 0/C to 233/sup 0/C. Examination of Great Salt Lake, Bonneville sediment pore water, and Jordan Valley well-water chemistry indicates that mixing a small percent of these fluids with warm spring water can cause substantial errors … more

Assessment of radiological impact of the inactive uranium-mill tailings pile at Salt Lake City, Utah

Description: One of the largest inactive uranium mill tailings piles in the United States is located within metropolitan Salt Lake City, Utah. A radiological survey was performed at this site during the fall of 1975. A series of field and laboratory analyses were performed to characterize the spread of contamination from the tailings pile to surrounding areas. These analyses provided a basis for discussion of the important pathways for transport of radioactivity to man. Measurements of radionuclide concentr… more

Geothermal direct-contact heat exchange. Final report

Description: A glass direct contact heat exchange column was operated in the laboratory at atmospheric pressure using hot water and normal hexane. Column internals tested included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1{sup 0}C for packing to 13{sup 0}C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the … more

Tritium containment and blanket design challenges for a 1 GWe mirror fusion central power station

Description: Tritium containment and removal problems associated with the blanket and power-systems for a mirror fusion reactor are identified and conceptual process designs are devised to reduce emissions to the environment below 1 Ci/day. The blanket concept development proceeds by starting with this emission goal of 1 Ci/day and working inward to the blanket. At each decision point, worker safety, operational labor costs, and capital cost tradeoffs are contrasted. The conceptual design uses air for the r… more

Silica scale technology and water conservation. [Recirculating evaporative cooling]

Description: Conservation of water at the Los Alamos Scientific Laboratory (LASL) has been accomplished by recirculating evaporative cooling waters. Because of high silica concentration (80 mg/l) in Los Alamos groundwater, the concentration of recirculating water must be carefully controlled to prevent scaling. The most troublesome scale at Los Alamos has been identified as colloidal silica bound in a crystalline matrix of calcium carbonate. Several approaches to controlling this scale are: (1) chemical tre… more

Chemically reactive turbulent plumes

Description: This paper describes an investigation into the practicality of using a probability density function of joint concentrations as the primary dependent variable in a description of a turbulent reactive flow. It has been established in the last decade that this manner of prescription of reactive flows has profound theoretical advantages over a moment formulation especially for rapidly reacting species and for non-isothermal reactive systems. However, since the probability density function contains … more

Geologic feasibility of talc and serpentinite bodies from the Appalachian Mountain region of eastern United States with regard to siting of radioactive-waste repositories. Part I. Additional conclusions relating to ultramafic rocks. Part II. Field investigations of talc and serpentinite deposits. Supplementary report

Description: Ultramafic rocks and serpentinites appear to have many favorable features that make them worthy of further consideration. Such rock types are widely distributed in this country and display wide variations in their physical properties, based largely on the degree of serpentinization and mineral content. For example, serpentinite has certain self-sealing and flowage characteristics that render it impermeable at depth, whereas unserpentinized ultramafic rocks are structurally very rigid and strong… more
