The objective of this study was to extend the working life of cutting fluids used in metal machining operations at LLNL. The characteristics of the fluids in nine different machines were studied. The pH, bacteria level, percent coolant concentrate, percent tramp oil, and total undissolved solids were monitored on a week-to-week basis for 6 weeks. During this time, the criteria and procedures used for changing the cutting fluids in the machines were also observed. Although the study is incomplete, the following recommendations were made. Cutting fluids should be diluted with deionized water and the concentration of the cutting fluid should be monitored regularly with a refractometer. A bactericide should be added to the cutting fluid. The machines should have a thorough initial cleaning and machine oil leaks should be eliminated. Only one cutting fluid should be used throughout the shop. Methods for removing metal particles from used cutting oils should be investigated. (LCL)

The Southwest Residential Experiment Station (SW RES) is operated in Las Cruces, New Mexico. Physical performance data obtained from the photovoltaic energy systems under test at the SW RES for the month of November 1981, are tabulated.

A nondestructive evaluation (NDE) program has been carried out using holographic interferometry, microradiography, and eddy current testing for the inspection of electron beam braze joining of dissimilar metals. Stainless steel tubing was joined to a gold-copper disk using a Cusil (copper/silver) brazing alloy. Holographic interferometry provided an indirect measure of strength by detecting the plastic deformation occurring as a result of applying a stress. Microradiography with the aid of computer graphics displays provided a means of measuring braze penetration into the stainless steel tube. Correlation of results with metallographic examination and microhardness measurements show that holography and microradiography each provide quantitative braze quality rankings. Each method correctly identified variations in braze quality independent of electron beam power (the only processing variable in sample fabrication). Eddy current results were consistent with the other NDE methods but appear to be based on variation in surface topography rather than electrical conductivity. The usefulness of the eddy current method for this problem is questionable due to its sensitivity to the small, complex test piece geometry.

This report addresses one of the possible uses of isotopic tracers, produced by laser-assisted iostope separation, in the investigation of pollution problems. Specifically, the use of laser-produced sulfur isotopes to analyze the acid rain situation is considered as it is a most important application of this technique. The proposed use of isotopically-labelled SO/sub 2/, in particular of /sup 36/SO/sub 2/, as a tracer can help elucidate the chemical and transport facets in a unified experiment. Separation of a sufficient quantity of the rare /sup 36/S isotope to perform several of these tracer studies appears to be practical and economical. This overall process is certainly deserving of further investigation.

Preliminary calculations at LLNL indicate that a Technology Demonstration Facility (TDF) consisting of a tandem mirror machine about the size of TMX could begin providing fusion nuclear engineering data as early as 1988. With high density operation based on physics already demonstrated in TMX, this machine would produce 12 MW of DT neutrons in steady-state from a plasma column 0.08 m in radius and 8 m in length. Allowing space for neutral beam injectors at each end of the column, this would permit testing of blanket modules and components at 1 MW/m/sup 2/ neutron wall load over a cylindrical surface 8 m/sup 2/ in area at a radius of 0.25 m; or one could irradiate thousands of small samples at 2 MW/m/sup 2/ at r = 0.125 m (4 m/sup 2/ area). With improved end-plug physics to be tested in TMX-Upgrade in 1982-83, the wall load at 0.25 m could be increased to 2 MW/m/sup 2/ (4 MW/m/sup 2/ at r = 0.125 m). Construction of the TDF could begin in FY84 and be completed in 4 to 5 years, at a cost roughly estimated as $700M in '81 dollars including engineering and 30% contingency.

A novel method for reducing the magnetohydrodynamic (MHD) pressure drops in the liquid metal flow in a heat pipe wick is described. By flattening the heat pipe, the eddy current return path in the metallic heat pipe wall is inreased significantly, thereby increasing the effective wall resistance. This, in turn, reduces the magnitude of the MHD pressure drop. The same principle can also be applied to flows of liquid metal coolants in a magnetic field.

An extensive amount of data were obtained from measurements of protonproton elastic scattering up to 5 GeV/c. We summarize physics learned from these data as well as other related experimental results.

The objectives of Operation Poorman were to design and build a portable seismic system and to set up and use this system in a cold-weather environment. The equipment design uses current technology to achieve a low-power, lightweight system that is configured into three modules. The system was deployed in Alaska during wintertime, and the results provide a basis for specifying a mission-ready seismic verification system.

The shock-hardened new-concept safing, arming, and in-line fuzing system developed for US Air Force modular weapons is being advanced for the Tactical Airfield Attack Munition (TAAM) as an alternate fuzing system. The high power slapper detonator system is being reduced in volume by an approximate factor of 10 and the energy by a factor of 3. In addition, the fuze has the capability of functioning after many hours of delay to provide area-denial capabilities.

Measurements of thermal conductivity, thermal diffusivity, and thermal linear expansion have been made on two rock types, a rock salt and a quartz monzonite, at temperatures from 300 to 573{sup 0}K and confining pressures from 10 to 50 MPa. The samples were taken from deep rock formations under consideration as possible sites for a nuclear waste repository - the rock salt from a domal salt formation at Avery Island, Louisiana, and the quartz monzonite from the Climax Stock, Nevada Test Site, Nevada. The testing temperature and pressures are meant to bracket conditions expected in the repository. In both rock types, the thermal properties show a strong dependence upon temperature and a weak or non-dependence upon confining pressure. Thermal conductivity and diffusivity both decrease with increasing temperature in approximately linear fashion for samples which have not been previously heated. At 50 MPa in both rocks this decrease closely matches the measured or expected intrinsic (crack-free) behavior of the material. Preliminary indications from the quartz monzonite suggest that conductivity and diffusivity at low pressure and temperature may decrease as a result of heat treatment above 400{sup 0}K.
