Actinide removal from aqueous solution with activated magnetite

Description: An actinide aqueous waste treatment process using activated magnetite has been developed at Rocky Flats. The use and effectiveness of various magnetites in lowering actinide concentrations in aqueous solution are described. Experiments indicate that magnetite particle size and pretreatment (activation of the magnetite surface with hydroxyl ions greatly influence the effective use of magnetite as an actinide adsorbent. With respect to actinide removal, Ba(OH)/sub 2/-activated magnetite was more … more

Magnetic mirror fusion systems: Characteristics and distinctive features

Description: A tutorial account is given of the main characteristics and distinctive features of conceptual magnetic fusion systems employing the magnetic mirror principle. These features are related to the potential advantages that mirror-based fusion systems may exhibit for the generation of economic fusion power.

The Department of Energy's collection procedures for defaulted Geothermal Loan Guaranties

Description: Delays of up to 2 years were experienced in liquidating $9.5 million in collateral on three defaulted loans. Although the Department had paid lenders $32.5 million on these defaulted loans, it had not notified the US Attorney General. Also, it had not prepared final liquidation plans as provided by regulations. As a result of these delays, the collective value of the collateral has decreased by about $2.7 million, and the Department has incurred over $690,000 in lease maintenance and administra… more

D-Zero Colling Loops

Description: This report provides the necessary sizing for the LN{sub 2} cooling coils in the D-Zero cryostats. Natural convection from finned tubes will be the means of cooling the cryostats and their contents until such time as liquid can be made by condensing. Each cryostat will contain three separate cooling runs. Two runs will be cooldown and the other steady state. These runs will be placed in each cryostat as shown in figure 3, 4a and 4b. By assuming a 100 K tube wall temperature, tube diameter (3/4-… more

Radiation effects and annealing kinetics in crystalline silicates, phosphates and complex Nb-Ta-Ti oxides. FInal Report

Description: Interaction of heavy particles (alpha-recoil nuclei, fission fragments, implanted ions) with ceramics is complex because they have a wide range of structure types, complex compositions and chemical bonding is variable. Radiation damage can produce diverse results, but most commonly, crystalline periodic materials become either polycrystalline or aperiodic (metamict state). We studied the transition from crystalline to aperiodic state in natural materials that have been damaged by alpha recoil n… more
