Plans for the development of the IFR (Integral Fast Reactor) fuel cycle

Description: The Integral Fast Reactor (IFR) is a concept for a self-contained facility in which several sodium-cooled fast reactors of moderate size are located at the same site along with complete fuel-recycle and waste-treatment facilities. After the initial core loading with enriched uranium or plutonium, only natural or depleted uranium is shipped to the plant, and only wastes in final disposal forms are shipped out. The reactors have driver and blanket fuels of uranium-plutonium-zirconium alloys in st… more

Design methodologies for energy conservation and passive heating of buildings utilizing improved building components. Progress report, 1 August 1977--31 October 1977

Description: Construction of the experimental building demonstrating light weight ceiling thermal storage tiles, transparent insulation assemblies, and specialized louvers is well underway. Difficulties in acquiring materials have put the building two weeks behind schedule. A superior heat mirror product is being used in place of the original proposed transparent insulation for the south windows. Negotiations are underway to acquire superior logging devices at no additional cost for monitoring the building.

Immobilization of IFR salt wastes in mortar

Description: Portland cement-base mortars are being considered for immobilizing chloride salt wastes produced by the fuel cycles of Integral Fast Reactors (IFR). The IFR is a sodium-cooled fast reactor with metal alloy fuels. It has a close-coupled fuel cycle in which fission products are separated from the actinides in an electrochemical cell operating at 500/degree/C. This cell has a liquid cadmium anode in which the fuels are dissolved and a liquid salt electrolyte. The salt will be a mixture of either l… more

Evaluation of available MHD seed-regeneration processes on the basis of energy considerations

Description: Of the several processes described in the literature that are capable of separating sulfur from alkali-metal sulfates, seven processes were selected as candidates for regenerating seed material for reuse in open-cycle MHD. After a brief assessment of each process, two were selected for a detailed analysis, namely, a process developed by the Pittsburgh Energy Research Center (PERC) and a modified version of the Tampella process. The processes were compared on the bases of energy requirements and… more

Choice of pyroprocess for Integral Fast Reactor fuel

Description: A design objective for the Integral Fast Reactor (IFR) is fuel self sufficiency. This can be achieved only by employing chemical reprocessing as part of the fuel cycle. Because the fuel is a metal alloy (U-Pu-Zr), direct production of metal is highly advantageous. This makes a pyrometallurgical process attractive. (JDB)

Proposed methods for treating high-level pyrochemical process wastes. [Integral Fast Reactor]

Description: This survey illustrates the large variety and number of possible techniques available for treating pyrochemical wastes; there are undoubtedly other process types and many variations. The choice of a suitable process is complicated by the uncertainty as to what will be an acceptable waste form in the future for both TRU and non-TRU wastes.

Surface-spark discharges compared with exploding wires/films as high temperature uv sources. [40,000/sup 0/K]

Description: Extensive experimental studies of electrically exploded 0.05- to 0.25-mm-diameter metal wires and film thicknesses from 0.1 to 10 ..mu..m (coated on 0.6- to 10.0-cm diameter substrates) were made for lengths from 3.0 to 100 cm. These exploded metal-conductor-initiated discharges proved to be excellent sources for intense radiation in the near-ultraviolet range, 200 to 300 nm, with brightness temperatures measured over 40,000 K. The impedance-matching characteristics and scaling laws developed t… more

Process to remove rare earth from IFR electrolyte

Description: The invention is a process for the removal of rare earths from molten chloride electrolyte salts used in the reprocessing of integrated fast reactor fuel (IFR). The process can be used either continuously during normal operation of the electrorefiner or as a batch process. The process consists of first separating the actinide values from the salt before purification by removal of the rare earths. After replacement of the actinides removed in the first step, the now-purified salt electrolyte has… more

Partition of actinides and fission products between metal and molten salt phases: Theory, measurement, and application to IFR pyroprocess development

Description: The chemical basis of Integral Fast Reactor fuel reprocessing (pyroprocessing) is partition of fuel, cladding, and fission product elements between molten LiCl-KCl and either a solid metal phase or a liquid cadmium phase. The partition reactions are described herein, and the thermodynamic basis for predicting distributions of actinides and fission products in the pyroprocess is discussed. The critical role of metal-phase activity coefficients, especially those of rare earth and the transuranic … more

New high-level waste management technology for IFR pyroprocessing wastes

Description: The pyrochemical electrorefining process for recovery of actinides in spent fuel from the Integral Fast Reactor accumulates fission product wastes as chlorides dissolved in molten LiCI-KCI and as metals, some of which are in molten cadmium. Pyrochemical processes are being developed to recover uranium and transuranium elements for return to the reactor, and to separate and immobilize fission products in suitable waste forms. Solvent cadmium is recycled within the process. Electrolyte salt is tr… more

Condensation and deposition of seed in the MHD bottoming plant

Description: The computer models of slag vapor nucleation and particle deposition have been extended to predict the growth and deposition of seed particles in the steam and air heater sections of the MHD bottoming plant. The model represents a hot combustion gas stream, which contains vaporized seed and entrained slag particles of a selected initial size distribution, flowing through a bank of cooled tubes. The energy balance includes convective and radiant heat transfer to the cool surfaces. The material b… more

Measurement of photodynamic therapy drug concentrations in a tissue

Description: This is the final report of a one-year laboratory-directed research and development project at the Los Alamos National Laboratory (LANL). Photodynamic therapy (PDT) is an experimental treatment modality for cancer in which a photoactive molecule with an affinity for tumors in administered to the patient, then excited by light. Photoactivation creates singlet oxygen consequently killing the tissue. Knowledge of the concentration of the photoactive compound in the tissue is necessary for proper l… more

Correlation of the growth of Chinese hamster V/sub 2/79-171b multicellular spheroids with cytokinetic parameters

Description: The volumes of Chinese hamster V/sub 2/79-171b multicellular spheroids grown in spinner culture were measured and correlated to DNA distribution and cell volume distribution information. Spheroid growth curves were obtained over a 21 day period using both electronic cell volume measurements and microscope micrometer sizing. The spheroids were collected from the aperture tube after electronic sizing, and single cell suspensions were prepared via trypsinization. Saline-washed cells were then stai… more
