In this document we present the results of our analysis of data from 16 three-component seismometers and 8 dynamite explosions around the Medicine Lake volcano's Glass Mountain in northern California. The Medicine Lake volcano is located just northeast of the southeastward-trending Cascade Range of shield and small composite volcanoes. 2 refs., 6 figs.

In our recent experiments on the TMX-U thermal-barrier device, we achieved the end plugging of axial ion losses up to a central cell density of n/sub c/ = 6 x 10/sup 12/ cm/sup -3/. During lower density experiments, we measured the axial potential profile characteristic of a thermal barrier and found an ion-confining potential greater than 1.5 kV and a potential depression of 0.45 kV in the barrier region. The average beta of hot end plug electrons has reached 15% and of hot central cell ions has reached 6%. In addition, we heated deuterium ions in the central cell with ICRF to an average perpendicular energy of 2 keV. During strong end plugging at low density (7 x 10/sup 11/ cm/sup -3/), the axial ion confinement time tau/sub parallel/ reached 50 to 100 ms while the nonambipolar radial ion confinement time tau/sub perpendicular/ was 14 ms - independent of end plugging. Electrically floating end walls increased the radial ion confinement time by a factor of 1.8. At higher densities and lower potentials, tau/sub parallel/ was 6 to 12 ms and tau/sub perpendicular/ exceeded 100 ms.

The procedure was designed for the simple, rapid determination of the Fe(II)/Fe(III) ratio in glass samples. The procedure consists of the following steps: dissolution of the pulverized glass sample in a sulfuric-hydrofluoric acid mixture, containing ammonium vanadate, which preserves the Fe(II) content; addition of boric acid to destroy iron-fluoride complexes, making the iron available for color formation with Ferrozine; addition of pH 5 buffer and Ferrozine reagent to form the magenta-colored ferrous-Ferrozine complex, with measurement of the absorbance for the determination of Fe(II) content; and, addition of ascorbic acid to reduce Fe(III) to Fe(II), with a second absorbance measurement that determines total Fe. Directions for the preparation of glass from non-radioactive sludge samples are provided. The analysis of this prepared glass for the Fe(II)/Fe(III) ratio is an indication of the ratio that would be in a plant batch of glass if made from this sludge.

This paper presents selected preliminary results obtained during the first 54 days of the Prototype Engineered Barrier System Field Tests (PEBSFT) that are being performed in G-Tunnel within the Nevada Test Site. The test described is a precursor to the Engineered Barrier Systems Field Tests (EBSFT). The EBSFT will consist of in situ tests of the geohydrologic and geochemical environment in the near field (within a few meters) of heaters emplaced in welded tuff to simulate the thermal effects of waste packages. The PEBSFTs are being conducted to evaluate the applicability of measurement techniques, numerical models, and procedures for future investigations that will be conducted in the Exploratory Shaft Facilities of the Yucca Mountain Project (YMP). The paper discusses the evolution of hydrothermal behavior during the prototype test, including rock temperatures, changes in rock moisture content, air permeability of fractures, gas pressures, and rock mass gas-phase humidity. 10 refs., 12 figs.

The Mirror Advanced Reactor Study (MARS) is a conceptual design of a 1200-MWe commercial tandem mirror reactor for electricity and synfuels (methanol) production. Thermal barrier end plugs of the TMX-U/MFTF-B type allow steady-state ignition of a 130-m-long central-cell DT plasma. Compact, gridless direct converters supply all the plant auxiliary power. The simple lead-lithium eutectic-cooled blanket has high neutron energy multiplication (1.36) as well as a low tritium inventory (< 8 g), and it will not melt in accidents.

Mixtures of CTCl/sub 3//CDCl/sub 3/ were successfully detritiated by 12..mu.. laser multiple-photon dissociation. The lower limit of the T/D enrichment factor was determined to be approx. 165. Additional studies concerning the effects of pulse energy, irradiation geometry and sample pressure were conducted. Characterization of both untuned and tuned NH/sub 3/ laser configurations were completed. Further laser studies considered implementation of a short pulse CO/sub 2/ laser pump source for either the current NH/sub 3/ laser or for possible use in a rotational Raman laser. Process engineering requirements for T/D separation at Savannah River were studied in detail and the first complete process design for implementation is presented.

Final comparisons are made between measured and calculated radiation doses around the holes in which the spent fuel was emplaced in the Spent Fuel Test - Climax. Neutron doses were found to be negligible compared with gamma doses. Good agreement was found between the doses predicted by Monte Carlo calculations and those measured by short-exposure thermoluminescence dosimetry. Poor agreement was found between the calculational results and doses measured by exposure of LiF optical-absorption-type dosimeters for long periods, probably because of an inability to accurately correct for fade resulting from elevated temperature exposure over several months. The maximum dose to the rock occurred at the walls of the emplacement holes, and amounted to 1.6 MGy (1.6 x 10{sup 8} rad) in granite for the emplacement period of nearly 3 years. It is recommended that dose evaluations for future high-level nuclear waste storage facilities also be performed by combining calculations and dosimetry. Passive dosimetry techniques, if used, should involve short exposures, so that laboratory calibrations can be performed with duplicate time, temperature, dose rate, and dose parameters. An attractive alternative would be to use active ionization chambers, inserted only periodically. These could be calibrated under appropriate temperature and pressure conditions, and could …

The 99th Congress has before it several proposals to authorize additional U.S. contributions to multilateral development banks. These include potential subscriptions or contributions to the International Bank for Reconstruction and Development (IBRD), the International Finance Corporation (IFC), the African Development Fund (AFDF), and the special African aid facility of the International Development Association (IDA). There is no legislation now before Congress to authorize new contributions to the International Monetary Fund (IMF), the regular budget of the IDA, or any of the other regional development banks. These have been dealt with in previous years. This paper provides some background on the World Bank and a summary of the pending legislation.
