Carbon-14 immobilization via the Ba(OH)/sub 2/8H/sub 2/O process

Description: The airborne release of /sup 14/C from various nuclear facilities has been identified as a potential biohazard due to the long half-life of /sup 14/C (5730 yrs) and the ease in which it may be assimilated into the biosphere. At Oak Ridge National Laboratory, technology is under development, as part of the Airborne Waste Management Program, for the removal and immobilization of this radionuclide. Prior studies have indicated that the /sup 14/C will likely exist in the oxidized form as CO/sub 2/ … more

Decommissioning of a tritium-contaminated laboratory

Description: A tritium laboratory facility at the Los Alamos National Laboratory, Los Alamos, New Mexico, was decommissioned in 1979. The project involved dismantling the laboratory equipment and disposing of the equipment and debris at an on-site waste disposal/storage area. The laboratory, constructed in 1953, was in service for tritium research and fabrication of lithium tritide components until 1974. The major features of the laboratory included 25 meters of gloveboxes and hoods, associated vacuum lines… more

Facility for in-vivo measurement of lithium

Description: Although lithium, an alkali metal is found in trace quantities in human, animal and plant tissue, no essential function has yet been ascribed to it. The concentration of Li in normal human tissue is in the 0.01 ..mu..g/g range, being largest in the cortical bone - 0.12 ..mu..g/g. Lithium was first used clinically for the treatment of mania. The most important clinical effect today is the prophylactic action or its ability to attenuate or prevent recurrences of manic and depressive episodes. Whi… more

Tritium-target performance at RTNS-II

Description: The Rotating Target Neutron Source (RTNS-II) uses a 360-keV deuteron beam and the /sup 3/He(d,n)/sup 4/He reaction to generate 14-MeV neutrons. The neutrons are used for fusion materials damage studies. The tritium target consists of a band of titanium tritide on copper alloy substrates of 23- or 50-cm diameter. During operation, the substrates are internally cooled and rotated at approx. 4000 rpm to withstand beam intensities in excess of 100 mA. Neutron production data have been accumulated f… more

ICF with momentum-rich beams

Description: A novel approach to obtain thermonuclear ignitions condition is suggested. Utilizing state-of-the-art ion source brightness parameters, and high gradient acceleration columns, it is possible to focus 10 kJ of heavy ions to a few mm spot, using a 1-meter radius spherical ion source. Heavy ion energies of 500 to 1000 keV have the velocity required for volume ignition of DT. The beam mass is typically 10 times greater than that of the DT which is to be burned. A spherical array of ion sources is e… more

Inertial-confinement-fusion targets

Description: Much of the research in laser fusion has been done using simple ball on-stalk targets filled with a deuterium-tritium mixture. The targets operated in the exploding pusher mode in which the laser energy was delivered in a very short time (approx. 100 ps or less) and was absorbed by the glass wall of the target. The high energy density in the glass literally exploded the shell with the inward moving glass compressing the DT fuel to high temperatures and moderate densities. Temperatures achieved … more

Emanation of tritiated water from disposal sites at Los Alamos, New Mexico

Description: The level of contamination induced by the presence of tritiated water (HTO) on the Bandelier tuff near Los Alamos, New Mexico has been seen to decrease vertically and horizontally at the same rate. This decrease in radioactivity with distance from the source has been measured around three different disposal shafts and found to be somewhat slower than the decrease in emanation rate with distance from the source. Physical factors, suspected of influencing HTO emanation, were entered as independen… more

Development of advanced technologies for photochemical tritium recovery. Bi-quarterly progress report, July 1, 1981-December 31, 1981. [From heavy water]

Description: A process to photochemically remove tritium from heavy water has been described previously. Order-of-magnitude cost estimates for this process have been made, based on the specifications, assumptions, and parameters. The estimated costs of each unit and of the complete system are given. The total capital cost (excluding laser cost) of $650,000 corresponds to a cost of $0.08/Ci tritium removed, for plant amortization over one year. The electrical load is about 154 kW; this is equal to a cost of … more

Metabolic changes associated with shoot formation in tobacco callus cultures

Description: Callus tissue derived from Nicotiana tabacum L. stem pith parenchyma cells was grown either on medium which maintains the callus in an undifferentiated state, or on medium which induces the formation of shoots. Two complementary types of studies were performed with the goal of establishing metabolic markers for the initiation of shoot formation: one designed to characterize the flow of radioactive sucrose into various metabolic pools, and one which allowed measurement of intermediary metabolite… more

Assessment of microbial processes on gas production at radioactive low-level waste disposal sites

Description: Factors controlling gaseous emanations from low level radioactive waste disposal sites are assessed. Importance of gaseous fluxes of methane, carbon dioxide, and possible hydrogen from the site, stems from the inclusion of tritium and/or carbon-14 into the elemental composition of these compounds. In that the primary source of these gases is the biodegradation of organic components of the waste material, primary emphasis of the study involved an examination of the biochemical pathways producing… more

On-demand production of uniform DT droplets using pulsed electrohydrodynamic spraying. Charged Particle Research Laboratory report No. 1-82

Description: A technique suitable for on-demand production of uniform DT droplets is investigated using pulsed electrohydrodynamic (EHD) spraying. Liquid hydrogen is employed as the working liquid, into which charge is injected using a sharp tungsten needle raised to high voltage. By controlling this high voltage, the amount of charge injection required for disrupting the liquid surface into a smooth liquid jet of desired size is determined. For on-demand production of the liquid jet (which breaks up into u… more

Photon-activation therapy

Description: Photon Activation Therapy (PAT) is a technique in which radiation dose to tumor is enhanced via introduction of stable /sup 127/I in the form of iodinated deoxyuridine (IdUrd). Stimulation of cytotoxic effects from IdUrd is accomplished by activation with external (or implanted) radiation sources. Thus, accumulations of this nucleoside in actively competing cellpools do not preclude therapy in so far as such tissues can be excluded from the radiation field. Calculations show that 5% replacement… more
