Glass frit will be a major raw material for the operation of the Defense Waste Processing Facility. The frit will be controlled by certificate of conformance and a confirmatory analysis from a commercial analytical laboratory. The following effort provides additional quantitative information on the variability of frit chemical analyses at two commercial laboratories. Identical samples of IDMS Frit 202 were chemically analyzed at two commercial laboratories and at three different times over a period of four months. The SRL-ADS analyses, after correction with the reference standard and normalization, provided confirmatory information, but did not detect the low silica level in one of the frit samples. A methodology utilizing elliptical limits for confirming the certificate of conformance or confirmatory analysis was introduced and recommended for use when the analysis values are close but not within the specification limits. It was also suggested that the lithia specification limits might be reduced as long as CELS is used to confirm the analysis.

Some indirect measures of Japan's import barriers indicate that Japan's import behavior is unusual, but some do not. Japan's trade surplus is large, but the United States exports as much to that market as it does to other major industrialized nations. Japan's imports of manufactures, however, are low relative to levels in other industrialized nations.

The Boussinesq system describes weakly nonlinear dispersive long waves plasmas and incompressible irrotational fluids. This study presents some results regarding the structure and behavior of a system of equations that yield the spatial structure of triad interactions in the Boussinesq system. Such a system forms part of a model for the formation and evolution of sand ridges on the continental shelf. The aims of this study are to provide some insight into the behavior of the triad system and into the sand ridge model in particular.

Work continued on the development of the high-pressure helium-cooled design for the PULSAR reactor study. It was found that the high pressure helium-cooled solid breeder design may be able to breed adequate tritium without the use of Be as the neutron multiplier. Thermal-hydraulic results also indicate that the ARIES-IV shield can be used as the thermal storage component, while keeping outlet coolant temperature constant during the dwell time of about 2 minutes. During this period, two TE{sub 22,6} mode generators were fabricated and a report on the testing of the RF vacuum feed-throughs were written. Also, the DiMES sample chamber was operated in a piggyback mode and different samples were exposed to the DIII-D plasma during dedicated physics experiments.

This invention is comprised of a pipe inspection instrument carriage for use with a pipe crawler or other locomotion means for performing internal inspections of piping surfaces. The carriage has a front leg assembly, a rear leg assembly and a central support connecting the two assemblies and for mounting an instrument arm having inspection instruments. The instrument arm has means mounted distally thereon for axially aligning the inspection instrumentation and means for extending the inspection instruments radially outward to operably position the inspection instruments on the piping interior. Also, the carriage has means for rotating the central support and the front leg assembly with respect to the rear leg assembly so that the inspection instruments azimuthally scan the piping interior. The instrument carriage allows performance of all piping inspection operations with a minimum of moving parts, thus decreasing the likelihood of performance failure.

This invention is comprised of a pipe crawler having a midsection that provides the stability and flexibility to allow the pipe crawler to negotiate curved and uneven segments of piping while traveling through piping systems. The pipe crawler comprises a front leg assembly, a rear leg assembly, a midsection with a gimbal at each end for connecting the midsection to the front and rear leg assemblies in a flexible manner, and an air cylinder for changing the distance between the front and rear leg assemblies. The pipe crawler moves in ``inch worm`` fashion with the front and rear leg assemblies alternating between an extended and a retracted position as the air cylinder moves the retracted leg assembly forward. The midsection has a plurality of legs extending radially for holding the midsection within a maximum displacement from the piping axis so that the gimbals are not pivoted to extreme angles where they might lock up or seize. When the midsection is displaced sufficiently, its legs with wheels on each end engage the interior surface of the piping and prevent further displacement. Using two gimbals divides the angle between the planes defined by the front and rear leg assemblies which also helps …

The goal of this research was to develop the understanding of the structure/property relations in Y{sub 2}O{sub 3}-stabilized cubic ZrO{sub 2} (Y-CSZ) single crystals with emphasis on the potential use of these materials as a fibrous reinforcement for high temperature structural applications. In particular, the issues addressed include: (i) determination of the structure of as-grown Y-CSZ and its relation to the deformation behavior and (ii) initial fiber growth and evaluation. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.
