The Omega West Reactor (OWR) is a water-cooled pool reactor operated by for the DOE by Los Alamos National Laboratory (LANL) for neutron irradiation experiments at a power of 8 MWt... 

Radioactive plutonium isotopes emit alpha particles. The amount of radioactive plutonium in a sample can be measured by alpha spectroscopy, a technique for counting the alpha radiation. The technique is used at the Los Alamos National Laboratory (LANL) in New Mexico in order to monitor employees for exposure. 

Personnel working in some programs at the Los Alamos National Laboratory (LANL) may handle radioactive materials that, under certain circumstances, could be taken into the body. Employees are monitored for such intakes through a series of routine and special bioassay measurements. One such measurement involves a thermal ionization mass spectrometer. In this technique, the metals in a sample are electroplated onto a rhenium filament. This filament is inserted into the ion source of the mass spectrometer and a current is passed through it. The ions of the plutonium isotopes are thus formed and then accelerated through the magnetic held. The number of ions of each isotope are counted and the amount of Pu-239 in the original sample calculated by comparison to a standard. 

The test plan that was executed at Holston Army Ammunition Plant (HAAP) demonstrated that the hydrolysis process for the energetic materials of interest successfully destroyed more than 99.7 percent of the energetics treated. Over 9,500 pounds of energetic materials were destroyed while encountering only the types of problems normally expected during the implementation of a new facility and process. The suite of tests performed at Los Alamos National Laboratory (LANL) and at HAAP covered a range of reaction temperatures and caustic concentrations. Under all these conditions, the destruction of energetics was carried out safely and effectively. 

Los Alamos National Laboratory (LANL) performed bench-scale testing in support of the engineering-scale hydrolysis reactor system. 

Archibald, Coburn, and Hiskey at Los Alamos National Laboratory (LANL) have reported a synthesis of TNAZ (18) that gives an overall yield of 57 % and is suitable for large scale manufacture. Morton Thiokol in the US now manufactures TNAZ on a pilot plant scale via this route. This synthesis starts from readily available formaldehyde and nitromethane, which under base catalysis form tris(hydroxymethyl)nitromethane (35), and without isolation from... 

Work at Los Alamos National Laboratory (LANL) was supported by the DOE Office of Basic Energy Sciences and by the LANL Laboratory Directed Research and Development program. LANL is operated by Los Alamos National Security, LLC, for the National Nuclear Security Administration of the US DOE under Contract No. DE-AC52-06NA25396. Work at University of Toledo was supported by NSF grant DMR-0606307. 

In 1996, the Los Alamos National Laboratory (LANL, also a DOE laboratory) made similar observations, noting that while capital costs rise slowly with contaminant concentrations, the cost of materials, operation and maintenance, and labor remains constant (DA, p. 59). 

In 1999, the SGS was used at the U.S. Department of Energy s (DOE s) Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, to sort 2526 yd of soil and debris contaminated with up to 431.46 picocuries per gram (pCi/g) of uranium from the production of nuclear weapons. The actual cost for the operation was 275,745. This figure included 6600 for predeployment activities, 46,000 for mobilization, 185,445 for processing, 35,000 for demobilization, and 2700 for the final report. LANL incurred 543,400 in additional costs for staff, the prime contractor, recharges, and soil disposal. The overall nnit cost was 109/yd of soil processed (D21040S, p. 70 D21230W, pp. 13, 14). 

Formulations based on nanoreactants also known as metastable intermolecular composites (abbreviated as MIC and pronounced as Mick , also referred to as super-thermites or nano-energetic mixtures) were first reported by U.S. Los Alamos National Laboratory (LANL) and appear to be very attractive for a number of applications [103]. Some important MICs are illustrated here along with their properties. 

Several other ICF reactor concepts use liquid metal walls (Ii W). These include the Los Alamos National Laboratory (LANL) wetted wall concept, the Bechtel concept called EAGLE (which uses a lithium spray in the chamber), the Lawrence Livermore National Laboratory (LLNL) concept called JADE (which uses a fiber-metal structure to control liquid metal flow), and the German/University of Wisconsin concept called HIBALL (which uses carbide "socks" to control liquid metal flow). 

Utilities. Los Alamos National Laboratory (LANL) has performed extensive analysis of the operating cost and energy consumption of a production size supercritical system based on actual running performance. The LANL data indicated electrical cost at. 090... 

In the early 1990s, an alternative low platinum loading catalyst layer structure was subsequently developed at the Los Alamos National Laboratory (LANL). In this structure, recast ionomer (rather than PEFE) is used to hold the catalyst layer structure together, and the low-loading catalyst layer is applied to the membrane... 

Five separate destruction technologies were tested for the destruction of waste HMX and PBX high explosives (HE). Since incineration is the baseline technology, a series of tests was conducted at a commercial two-stage, fixed-hearth incinerator. Destruction by molten salt injection was tested at LLNL. The last three destruction techniques are based on a base hydrolysis (BH) explosive pretreatment to produce a nonexplosive solution for further treatment. Three secondary treatments for BH were tested, including hydrothermal, biodegradation, and thermal decomposition. BH and hydrothermal techniques were tested at Los Alamos National Laboratory (LANL), and LLNL tested biological and thermal decomposition. 

However, despite the fact that in the natmal state the Navajo are mostly free from cancer, there are tragic uranium-derived consequences for the Navajos and other tribes, and for their land and water and also for others who have lived and worked around the manium mines and mine tailings, near test sites, and at the Los Alamos National Laboratory (LANL). These facts are amplified at a personal... 

Researchers at Advanced Technology Materials (ATM) and Los Alamos National Laboratory (LANL) have focused on the CVD synthesis of Tl-2212 thin films on MgO substrates [277]. Fluorinated MOCVD precursors were used to grow Ba-Ca-Cu-O (F) thin films which were then annealed in the presence of H2O/O2 to promote fluoride evolution. The films were placed face down between two TBCCO pellets and annealed. The resultant superconducting films exhibited average electrical properties with Tc = 108 K and 7. = 1 x in Acm at 90 K. 

The principal goal of this project is to demonstrate electrolysis technology using ceramic electrochemical cells based on solid oxide proton conductors. Los Alamos National Laboratory (LANL) has experience in solid-state bulk and thin... 

Department of Energy s Los Alamos National Laboratory (LANL). LANL, which is located in north-central New Mexico, has been involved in the research and development of nuclear-related materials for the past hve decades and is an excellent location to conduct this type of research. 

Los Alamos National Laboratory (LANL) and NSWC Indian Head Division (Yorktown, Virginia) are responsible for performing bench-scale tests to address ACW I Committee concerns about the solubility of energetics in alkaline solutions, the simultaneous processing of different types of energetics, and the reduction to the proper particle sizes for operation.
