Compilation of yields from neutron-induced fission of /sup 232/Th, /sup 235/U, /sup 236/U, /sup 237/Np, /sup 238/U, and /sup 239/Pu measured radiochemically at Los Alamos

Description: Radiochemically measured relative fission yields have been compiled for targets of /sup 232/Th, /sup 235/U, /sup 236/U, /sup 237/Np, /sup 238/U, and /sup 239/Pu that were irradiated with neutrons, the average energies of which were in the 0.0253-eV to 14-MeV range. The yields were examined for consistency by means of the two-mode-of-fission hypothesis. The circumstances associated with inconsistencies were investigated, but the yields in questions were rejected only when good cause was found. F… more

Hydrology of some deep mines in Precambrian rocks

Description: A number of underground mines were investigated during the summer of 1975. All of them are in Precambrian rocks of the Lake Superior region. They represent a variety of geologic settings. The purpose of the investigations was to make a preliminary study of the dryness, or lack of dryness of these rocks at depth. In other words, to see if water was entering the deeper workings through the unmined rock by some means such as fracture or fault zones, joints or permeable zones. Water entering throug… more

Measurement of wakefields generated in accelerator test structures using the SLC

Description: Research is underway at SLAC to develop accelerator structures for the next generation linear collider. An important feature of the design is a detuning of the dipole modes of the cells to suppress the long-range transverse wakefield by two orders of magnitude. This paper describes a facility, called ASSET, that will be incorporated into the SLAC Linear Collider (SLC) to test the long-range wakefield suppression and also to measure the other components of the wakefields generated in accelerator… more

Bubbles and their implications for laser-fusion

Description: Bubbles are concentrations of electromagnetic energy in the region of the critical density that force out the plasma to form a void. Since the critical density surface is cratered, absorption may be greater than a smooth surface since a larger area will be available for absorption and the reflected light will have a large probability of restriking the critical density. The distance between bubbles is several wavelengths and consequently they may encourage Rayleigh--Taylor instabilities. The thr… more

Observation of the forbidden magnetic dipole transition 6/sup 2/P/sub 1/2/. -->. 7/sup 2/P/sub 1/2/ in atomic thallium. [Interference, M1 and E1 amplitudes, polarization, fluorescence, hyperfine structure]

Description: A measurement of the 6/sup 2/P/sub 1/2/ ..-->.. 7/sup 2/P/sub 1/2/ forbidden magnetic dipole matrix element in atomic thallium is described. A pulsed, linearly polarized dye laser tuned to the transition frequency is used to excite the thallium vapor from the 6/sup 2/P/sub 1/2/ ground state to the 7/sup 2/P/sub 1/2/ excited state. Interference between the magnetic dipole M1 amplitude and a static electric field induced E1 amplitude results in an atomic polarization of the 7/sup 2/P/sub 1/2/ sta… more

LARC-1: a Los Alamos release calculation program for fission product transport in HTGRs during the LOFC accident

Description: The theoretical and numerical data base development of the LARC-1 code is described. Four analytical models of fission product release from an HTGR core during the loss of forced circulation accident are developed. Effects of diffusion, adsorption and evaporation of the metallics and precursors are neglected in this first LARC model. Comparison of the analytic models indicates that the constant release-renormalized model is adequate to describe the processes involved. The numerical data base fo… more

Coal Technology Program progress report, August 1976

Description: The first experiment utilizing the hydrocarbonization reactor in a recirculating fluidized bed mode was completed successfully. A residue carbonization experiment was completed in which there was no significant agglomeration in the fluidized bed reactor, but which was terminated prematurely because of a plug in the off-gas line. The characterization and settling tests of oils derived from the SRC process were continued. High-temperature coal block pyrolysis studies were completed to fill out a … more

Development of a geothermal thesaurus

Description: An attempt was made to develop a thesaurus of terminology associated with geothermal energy for use in the information storage and retrieval system of LBL's Geothermal Information Group. The development of the thesaurus is discussed, beginning with an outline of its subject scope, sources, and methods used in compiling the list of terms. The tendency was to include, rather than exclude, terms of unknown usefulness, and to provide paths through the thesaurus to make these terms accessible. The t… more

Power plant siting; an application of the nominal group process technique

Description: The application of interactive group processes to the problem of facility siting is examined by this report. Much of the discussion is abstracted from experience gained in applying the Nominal Group Process Technique, an interactive group technique, to the identification and rating of factors important in siting nuclear power plants. Through this experience, interactive group process techniques are shown to facilitate the incorporation of the many diverse factors which play a role in siting. In… more

Separation of radioactive krypton from carbon dioxide and oxygen with molecular sieves

Description: In the reprocessing of HTGR nuclear fuels, the off-gas cleanup system generates a stream containing about 1 percent krypton, 90+ percent CO/sub 2/, and various amounts of O/sub 2/, N/sub 2/, and xenon. The krypton is radioactive and must be separated from the CO/sub 2/ before it is bottled or zeolite-encapsulated for final disposal. A series of theoretical and experimental investigations to find the best method for separating CO/sub 2/ and krypton under the required conditions showed that 5A mo… more

Power threshold for neutral beam current drive

Description: For fully noninductive current drive in tokamaks using neutral beams, there is a power and density threshold condition, setting a minimum value for P{sup 3/2}/n{sup 2}. If this condition is not met, stationary state cannot occur, and a tokamak discharge will collapse. This is a consequence of the coupling between current and electron temperature, or between current drive efficiency and energy confinement time. 4 figs.

Effect of deposition conditions on the properties of pyrolytic silicon carbide coatings for high-temperature gas-cooled reactor fuel particles

Description: Silicon carbide coatings on HTGR microsphere fuel act as the barrier to contain metallic fission products. Silicon carbide coatings were applied by the decomposition of CH/sub 3/SiCl/sub 3/ in a 13-cm-diam (5-in.) fluidized-bed coating furnace. The effects of temperature, CH/sub 3/SiCl/sub 3/ supply rate and the H/sub 2/:CH/sub 3/SiCl/sub 3/ ratio on coating properties were studied. Deposition temperature was found to control coating density, whole particle crushing strength, coating efficiency… more

Issues in radioactive-waste management for fusion power

Description: Analysis of recent conceptual designs reveals that commercial fusion power systems will raise issues of occupational and public health and safety. This paper focuses on radioactive wastes from fusion reactor materials activated by neutrons. The analysis shows that different selections of materials and neutronic designs can make differences in orders-of-magnitude of the kinds and amounts of radioactivity to be expected. By careful and early evaluation of the impacts of the selections on waste ma… more
