Toxicology Studies of Lewisite and Sulfur Mustard Agents: Genetic Toxicity of Lewisite (L) In Chinese Hamster Ovary Cells
The cytotoxic clastogenic and mutagenic effects of the arsenic containing vesicant, Lewisite (L) [dichloro(2-chlorovinyl) arsine], have been investigated using Chinese hamster ovary cells. One hour exposures to Lewisite were cytotoxic in uM amounts. The cell survival response yields a D37 of 0.6 uM and an extrapolation number of 2.5. The mutagenic response at the hypoxantnine-guanine phosporibosyl transferase (HGPRT) locus was sporadic and not significantly greater than control values when cells were exposed over a range of 0.125 to2.0 uM. Sister chromatid exchange (SCE) induction, a measure of chromosomal rearrangement, was weakly positive over a range of 0.25 to 1.0 uM but the values were not significantly greater than the control response. Chromosomal aberrations were induced at 0.75 and 1.0 UMin one experiment and 0.5 and 0.75 uM in another experiment. The Induced values were significantly greater than the control values. Lewisite appears to be cytotoxic and clastogenic in our investigations but SCE and mutation at the HGPRT locus are not significantly greater than control values. Lewisita toxicity was in some ways similar to radiomimetic chemicals such as bleomycin.

Piping instability resulting from bellows misalignment
The failure of the single phase bellows and magnet test stand during quench testing of SSC dipole magnet DD0011 has led to much speculation about the inherent stability of operating SSC magnets. This note addresses the problem of instabilities resulting from both translational and angular misalignment between pipes connected by bellows in the general sense and with respect to the SSC single phase system specifically. Note that none of the instabilities referenced here result from bellows 'squirm'. Inelastic bellows failure is not within the scope of this work. The failure mode referenced here is an elastic instability. 3 refs., 7 figs.

Comparison of US/FRG accident condition fuel failure and release models
Although there are many differences between the High-Temperature Gas Cooled Reactor (HTGR) concepts being developed in the US and the High Temperature Reactor (HTR) concepts in the Federal Republic of Germany (FRG), the coated fuel particles are very similar. Significant benefits are achievable through cooperative research and exchange of information and data on the fuel performance and radionuclide retention in the coated fuel particles. This draft report describes cooperative work on HTGR safety research as agreed to in the "USA/FRG Umbrella Agreement for Cooperation in GCR Development: Safety Research Subprogram Plan," specifically, this work was conducted under Project Work Statement (PWS) S-6 titled "Fission Product Retention in Fuel," 9 refs., 12 figs., 4 tabs.

Studies of plasma confinement in linear and RACETRACK mirror configurations
During the period from November 1988 through April 1989 the experimental plasma physics program at UCLA produced several new results. The experiments were conducted on the toroidal RACETRACK device. Generation of a steady-state high-beta field-reversed configuration in one of the straight sections by the rotating electromagnetic wave technique is now routine and because of understanding gained in the course of experiments we succeeded in extending the range of operation was extended. The pressure balance relation was verified by independent pressure and magnetic field measurements for this field reversed-configuration. Studies of the equilibrium have been extended to spatial and temporal decay of the confining diamagnetic current. It has been observed, that the current decays on the resistive time scale due to electron-ion coulomb collisions. Current injection was also used to study the effects of mirror fields on toroidal currents and to reduce the neutral gas pressure for a given plasma density.

Processes of community development and responses of ecosystems to climate change
Our studies focus on attempting to understand the role of decomposer-primary producer linkages in successional dynamics. We are testing a series of hypotheses that relate changes in plant species composition during succession to changes in activity and structure of the soil microfloral and faunal community, dynamics of soil organic matter, and availability of soil nutrients. As these successional patterns are identified, they are being applied to understanding specific processes and mechanics involved in ecosystem development during recovery from moderate and severe disturbances. These findings are then being used in conjunction with simulation models to assess potential effects of climate change on ecosystems. Our research involves field studies in northwestern Colorado and southeastern Washington, laboratory studies, and simulation modeling. Ongoing projects include studies of response patterns of primary producer and soil microbial communities to nutrient additions (N, P, and sucrose), the function of mycorrhizal fungi in plant community development, and the dynamics of litter decomposition under semiarid conditions. New studies are being implemented to investigate the significance of nutrient transfers from VAM fungi to plants and plant-root exudate interactions, and to relate this to understanding their roles in succession.

Soudan 2 as a long baseline neutrino detector
In a nine month run with a 150 GeV proton beam and a conventional double horn neutrino beam aimed at the Soudan 2 detector, a search could be made for neutrino oscillations in the mode /nu//sub /mu// /yields/ /nu//sub /tau//. If evidence for oscillations is not found, new limits could be set extending the /Delta/m/sup 2/ excluded region from .3 eV/sup 2/ to .004 eV/sup 2/ at 90% confidence level. 7 refs., 4 figs.

The soudan 2 experiment
Soudan 2 is an 1100-ton tracking calorimeter which is being constructed to search for nucleon decay. The detector consists of finely segmented iron instrumented with drift tubes, and records three spatial coordinates and dE/dx for every gas crossing. Excellent event-reconstruction capability, particle identification, and muon sign and direction determination give superior rejection of the neutrino background to nucleon decay in many modes. The first 275 tons of Soudan 2 is operating and a charged-particle test beam calibration is under way. Construction is scheduled for completion in 1992. 4 refs., 6 figs., 2 tabs.

A review of the Model 5A uranium hexafluoride cylinder
Both the Model 5A (Monel 400) and 5A (Monel 400) Modified five-inch cylinders have been used at the Portsmouth GDP to withdraw, store, and ship highly enriched uranium hexafluoride. As a result of a generic cracking problem with Monel 400 valve-boss material, a cylinder modification was implemented in the mid 1970s. This modification resulted in the violation of the ASME ''Code'' stamp status of the Model 5A Modified cylinder. Hydrostatic testing-to- rupture data indicated that the Model 5A Modified cylinders had ruptured strengths equivalent to that of the original Model 5A cylinders. An independent consultant reviewed the available information and confirmed that the Model 5A Modified cylinders ''will with proper maintenance continue to perform satisfactorily for many additional years of service.'' Based on the test data and consultant's review, DOE approved continued use of the 5A Modified cylinder and also requested procurement of replacement 5B cylinders be expedited. Currently, the 5A modified cylinders are in the production, storage, shipment cycle, and a sufficient number of 5B cylinders has been ordered to accommodate the projected product shipping requirements for the Navy flow. 3 tabs.
