Increasing the Life of Cutting Fluids Used in the LLNL Machine Shop

Description: 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 incomplet… more

Nondestructive evaluation of electron-beam braze joins

Description: 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 comp… more

Feasibility of laser-separation of /sup 36/S and its use as an atmospheric tracer

Description: 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.… more

Tandem-mirror technology demonstration facility

Description: 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 per… more

Optimizing the heat pipe for operation in a magnetic field when liquid-metal working fluids are used

Description: 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.

Operation Poorman

Description: 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.

In-line fuzing development for tactical airfield attack munition (TAAM)

Description: 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.

Thermal Properties of Rock Salt and Quartz Monzonite to 573{Sup 0}K and 50-MPa Confining Pressure

Description: 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, Ne… more
