A survey of Big Trees Park was conducted in 1998 after soil samples taken in the park in 1993 and 1995 revealed higher-than-expected concentrations of plutonium (LLNL 1999). Big Trees Park is a public park in the city of Livermore, California located about one-half mile from Lawrence Livermore National Laboratory (LLNL). The pattern of241 Am distribution was the same as that for plutonium with levels significantly higher inside ornamental tree wells than outside the wells or at depths. Activity levels were well below EPA s residential preliminary remediation goal of 2.5 pCi/g (93 mBq/g) which may have necessitated cleanup. The source of the contamination was most likely sewage sludge from LLNL that was applied to the ornamental trees in the park. 

Since 1978, large-scale LNG spill tests have been conducted by a joint team from Lawrence Livermore National Laboratory (LLNL) and the Naval Weapons Center (NWC) (Koopman et al., 1981). The test site was located at NWC, China Lake, California. The program, sponsored primarily by the Department of Energy, had as its principal objective the acquisition of data to aid in modeling both vapor dispersion and thermal radiation effects (from LNG vapor cloud fires). 

A combined team of scientists from the Lawrence-Livermore National Laboratory (LLNL) in California, and from the laboratory in Dubna, Russia, reported the following hot fusion reaction ... 

Carbon aerogel capacitive deionization (CA-CDI) is an ex situ technology under development by Lawrence Livermore National Laboratory (LLNL), which uses carbon aerogel electrodes to... 

HPO was developed by Lawrence Livermore National Laboratory (LLNL) and the University of California. It is currently licenced to SteamTech, Inc., and Integrated Water Technologies, Inc. The technology is commercially available. 

At GNS a search for element 114 was started in November-December, 1998. The experiments were performed in collaboration between the Flerov Laboratory of Nuclear Reactions, FLNR, and the Lawrence Livermore National Laboratory, LLNL, Livermore, California. A 244Pu target was irradiated for a period of 34 days with a 48Ca beam. One decay chain was extracted from the data. The chain was claimed to be a candidate for the decay of289114. The measured cross section was 1 pb [47],... 

U.S. and one industrial waste water treatment in Spain. Engineering scale field experiments have been conducted by the National Renewable Energy Laboratory (NREL) at the Lawrence Livermore National Laboratory (LLNL) treating ground water contaminated with trichloroethylene (TCE) [253]. This field system consisted of 158 m2 of parabolic trough reactors and used De-gussa P25 particles (0.1%) as the photocatalyst in a slurry flow configuration. With this relatively low titanium dioxide content the TCE concentration was reduced from 200 ppb to less than 5 ppb. 

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). 

The standard test for military explosives uses 5 g for the sample size (1 g for initiating explosives). The samples are heated for 40 h at various temperatures (90, 100, 120, 135, and 150°C). The results of the tests are reported as standard cubic centimeters of gas produced per 40 h at each of the specified temperatures. A similar test conducted by Lawrence Livermore National Laboratory (LLNL) uses 1-g samples heated at 120°C for 48 h. 

The Marshall Islands Dose Assessment and Radioecology Project has been in existence at Lawrence Livermore National Laboratory (LLNL) since 1973. It was a program of the Health and Ecological Assessment Division (HEA), in the Environmental Programs Directorate at LLNL. The primary purpose of this program was to assess the radiological conditions in the Marshall Islands. 

Seven polyurethane adhesives have been developed at Lawrence Livermore National Laboratory (LLNL). These adhesives, designated Halthanes were synthesized because of OSHA restrictions on the use of the curing agent methylene bis(2-chloroani1ine). Four of the Halthanes were made fromLLNL-developed 4,4 -methylene bis(phenylisocyanate) terminated prepolymers cured with a blend of polyols three were made from an LLNL-developed prepolymer terminated with Hylene W and cured with aromatic diamines. In this paper we report the dynamic mechanical and thermal behavior of these seven segmented polyurethanes. 

The Lawrence Livermore National Laboratory (LLNL) report summarizes much of the technical information needed to fill in information gaps about several new technologies for the destruction of energetic materials. 

A few years ago, Pekala and the staff of the Lawrence Livermore National Laboratory (LLNL) [13] made organic aerogels. Pekala et al. employed organic reactions that proceed through a sol-gel transition. What is more, the interac-...
