This report gives a brief description of the Molten Tin Process for nuclear fuel reprocessing, and summarizes the available data on thermodynamics and kinetics that pertain to the process. The two main reactions of concern in the process are illustrated by: MO/sub 2/(s) + 2C(in Sn sol'n) ..-->.. M(in Sn sol'n) + 2CO(g), and M(in Sn sol'n) + 1/2 N/sub 2/(g) ..-->.. MN(s), where M represents U or some other element in an oxide fuel. It is especially important for the Molten Tin Process to have information on the chemical activities of metals dissolved in tin at temperatures in the vicinity of 1900/sup 0/K. Sufficient thermodynamic and kinetic information is presented in this report to show that the various steps in the Molten Tin Process are scientifically feasible, but more information will need to be experimentally determined to work out a detailed process flow sheet.

Optical ionization effects in gases appear to be very sensitive indicators of nonuniformities caused by contamination, deformation, and other factors affecting a metal surface. These optical effects are influenced by surface electron emission, which is influenced in turn by the chemical, metallurgical, and mechanical condition of the metal surface. Based on these effects, a general technique for inspection of critical parts that is fast, inexpensive, nondestructive, and not limited by size or geometry is presented. Ionization effects that reveal nonuniformities and were recorded with standard photographic equipment are shown.

Two types of direct converters at up to 100 keV were tested. A beam direct converter was tested on a reduced area TFTR source at the Lawrence Berkeley Laboratory (LBL). After surface conditioning and outgassing, the efficiency was over 60% at the beginning of a pulse. During a pulse, the efficiency decreased as the gas density built up. A single-stage plasma direct converter with immersed grids is being tested on a steady-state ion beam with 6 kW of beam power. The power density at the grids can be varied by adjusting the beam focus. Recovery efficiencies over 70% are measured and we are now studying various loss mechanisms.

A crossed molecular beam study was made of the reactions of U with inorganic oxidizers (O/sub 2/, NO, SO/sub 2/, N/sub 2/O, CO/sub 2/), water, alcohols, acetone, and halogenated methanes. Results show that U in the gas phase behaves very much like most other heavy metals, and may be called a heavy Ba or Sn atom. 8 figures. (DLC)

Recent results obtained by using a 10 channel, filtered XRD detector system to record sub-keV x-ray emission from laser-irradiated targets are reported. Targets materials were Be, Al, Ti, Sn, Au and U, with Z ranging from 4 to 92. Targets were irradiated with 1ns FWHM, 1.06 ..mu..m wavelength pulses at an intensity of 5 x 10/sup 14/ W/cm/sup 2/. Time-resolved x-ray emission pulses show systematic and striking variations with Z. These variations can most probably be attributed to the onset of inhibited electron conduction. Time-integrated x-ray yields are obtained as a function of target Z as well as calculated charge states anti Z, indicating the type of physical processes that give rise to the x-ray emission. Typical sub-keV x-ray spectra are presented; in some cases such as Ti where prominent lines are present, the charge state of the plasma can be directly deduced from line ratios, agreement with numerical simulation is very good.

The calculation of the electronic motion in the pre-oscillation phase of a smooth bore magnetron is the problem of calculating the electronic motion in the region between two concentric cylinders with an applied radial electric field and a constant axial B/sub z/ magnetic field. The inner cylinder represents the electron emitting cathode and the outer cylinder represents the anode. The emission is assumed to be space charge limited. This results in an electronic cloud surrounding the cathode. The radial velocity of the electrons is limited by the space charge and in addition the axial magnetic field tends to curve the path of the electrons so that they return to the cathode. Consequently, the electronic orbit extends to some distance r/sub 0/ from the cathode and for values of the radius r > r/sub 0/ exists a charge free region. The model assumes relativistic electronic motion with self-consistent magnetic fields. The magnetic flux is assumed to be conserved; i.e., conducting cylindrical walls.

Advanced imaging methods have been evaluated for the purpose of constructing images of objects from ultrasonic data. Feasibility of imaging surfaces which are off-normal to the sound beam has been established. Laboratory results are presented which show a complete image of a typical core component. Using the previous system developed for under sodium viewing (USV), only normal surfaces of this object could be imaged. Using advanced methods, surfaces up to 60 degrees off-normal have been imaged. Details of equipment and procedures used for this image construction are described. Additional work on high temperature transducers, electronics, and signal analysis is required in order to adapt the off-normal viewing process described here to an eventual USV application.

Thermal barriers are localized reductions in potential between the plugs and the central cell, which effectively insulate trapped plug electrons from the central cell electrons. By then applying electron heating in the plug, it is possible to obtain trapped electron temperatures that are much greater than those of the central cell electrons. This, in turn, effects an increase in the plug potential and central cell confinement with a concomitant decrease in plug density and injection power. Ions trapped in the barrier by collisions are removed by the injection of neutral beams directed inside the barrier cell loss cone; these beam neutrals convert trapped barrier ions to neutrals by charge exchange permitting their escape. We describe a zero-dimensional physics model for this type of reactor, and present some preliminary results for Q.

A high-speed rotating shutter was designed to operate in a 10/sup -6/ Torr vacuum at the optical focus of a laser spatial filter. The shutter is basically a wheel, with a single 3 x 10-mm slot at the perimeter, which rotates with a peripheral speed of 1 km/s. The motor to drive the rotating wheel is magnetically suspended and synchronously wound. The wheel achieves a 4 ..mu..s opening time and a timing accuracy of better than 0.2 ..mu..s. (MOW)

Shiva is a 20 beam Nd:Glass Laser and Target Irradiation Facility at the Lawrence Livermore Laboratory. The laser system and integrated target facility evolved during the last year from a large, untested, experimental laser system to a target irradiation facility which has provided significant laser driven inertial confinement fusion data. The operation of the facility is discussed.

Different chemical pretreatments and filtration methods were evaluated as a possible means of clarifying and improving the injectivity of hypersaline brines. Six different downflow media combinations were evaluated over three geopressurized sites, using test data from 4 inch diameter filters. Also, tests were conducted with one hollow fiber ultrafilter unit and two types of disposable cartridge filters. The test procedures are mentioned briefly. (MHR)

The problems associated with the in vivo detection and measurement of actinides in the human lung are discussed together with various measurement systems currently in use. In particular, the methods and calibration procedures employed at the Lawrence Livermore Laboratory, namely, the use of twin Phoswich detectors and a new, more realistic, tissue-equivalent phantom, are described. Methods for the measurement of chest-wall thickness, fat content, and normal human background counts are also discussed. Detection-efficiency values and minimum detectable activity estimates are given for three common actinides, /sup 238/Pu, /sup 239/Pu, and /sup 241/Am.

A system for characterizing either a seismic source or geologic media from observational data was developed. This resulted from an examination of the forward and inverse problems of seismology. The system integrates many seismic monitoring research efforts into a single computational capability. Its main advantage is that it unifies computational and research efforts in seismic monitoring. 173 references, 9 figures, 3 tables.

The Hotspot quick-response unit was the solution to a requirement to find, identify, and control areas of radioactive contamination at the scene of a nuclear weapons accident. The unit consists of two trucks and two trailers, and is designed to be transported by one U.S. Air Force C-141. One truck (generator truck) carries a 40 kW generator-heater-air conditioner combination, spare tires, and accessories. The other (water truck) carries supplies and a 250-gal water tank. One trailer (counting trailer) contains detecting, counting, and recording equipment. The other (decontaminating trailer) contains a shower, sink, 30-gal hot water tank, and supplies.

QUERY is a computer program used for the retrieval of environmental data. The code was developed in support of the Imperial Valley Environmental Project of the Environmental Sciences division at Lawrence Livermore Laboratory to handle a multitude of environmentally related information. The program can run in either an interactive mode or production mode to retrieve these data. In either case, the user specifies a set of search constraints and then proceeds to select an output format from a menu of output options or to specify the output format according to his immediate needs. Basic data statistics can be requested. Merging of disparate data bases and subfile extraction are elementary.
