Effects of Overpressures in Group Shelters on Animals and Dummies
S>Relative biological hazards of blast were studied in two types of communal air-raid shelters during Shots 1 and 8. Dogs, restrained within the shelters during detonation, were studied pathologically and clinically for blast injuries. Two anthropometric dummies were test objects for displacement studies utilizing high-speed photography. Physical data included pressure vs time and air-drag determinations. During Shot 1, animals sustained marked blast damages (hemorrhages in lungs and abdominal organs), three dogs were ataxic. and the dummies were rather violently displaced. In Shot 8, however, no significant injuries were found in the animals, and the dummies were minimally displaced. Analysis of the physical data indicated that blast injuries and violent displacements may occur at much lower static overpressures than previously assumed from conventional explosion data. Furthermore, biological damage appeared to be related to the rate of rise of the overpressure and air drag, as well as the maximum overpressure values. (auth)

Extraction and recovery of plutonium and americium from nitric acid waste solutions by the TRUEX process - continuing development studies
This report summarizes the work done to date on the application of the TRUEX solvent extraction process for removing and separately recovering plutonium and americium from a nitric acid waste solution containing these elements, uranium, and a complement of inert metal ions. This simulated waste stream is typical of a raffinate from a tributyl phosphate (TBP)-based solvent extraction process for removing uranium and plutonium from dissolved plutonium-containing metallurgical scrap. The TRUEX process solvent in these experiments was a solution of TBP and octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO) dissolved in carbon tetrachloride. A flowsheet was designed on the basis of measured batch distribution ratios to reduce the TRU content of the solidified raffinate to less than or equal to 10 nCi/g and was tested in a countercurrent experiment performed in a 14-stage Argonne-model centrifugal contractor. The process solvent was recycled without cleanup. An unexpectedly high evaporative loss of CCl/sub 4/ resulted in concentration of the active extractant, CMPO, to nearly 0.30M in the solvent. Results are consistent with this higher CMPO concentration. The raffinate contained only 2 nCi/g of TRU, but the higher CMPO concentration resulted in reduced effectiveness in the stripping of americium from the solvent. Conditions can be easily adjusted to …

(High energy physics)
An intense analysis effort on the data we obtained in a seven month run on E704 last year has produced a flood of new results on polarization effects in particle production at 200 GeV/c. We are fortunate to be able to report in detail on those results. Our other Fermilab experiment, E683 (photoproduction of jets) has been delayed an unbelievable amount of time by Fermilab schedule slippages. It was scheduled and ready for beam two years ago As this report is being written, we have been running for two months and are expecting four months of production data taking. In this report we show some of our preliminary results. In addition we are near the end of a six month run on our CERN experiment, NA47 (SMC) which will measure the spin dependent structure functions for the proton and neutron. It is with a sense of relief, mixed with pride, that we report that all the equipment which we constructed for that experiment is currently working as designed. The random coincidence of accelerator schedules has left us slightly dazed, but all experiments are getting done and analyzed in a timely fashion. As members of the Solenoidal Detector Collaboration, we have …

Literature review of the concentration ratios of selected radionuclides in freshwater and marine fish
Concentration ratios (CR's) used for modeling the uptake and food chain transport of radionuclides in fish have usually been conservative; that is, at the high end of reported values. This practice ensures that the dose to the consumer of contaminated fish will not be underestimated. In many models, however, conservative values have been used for all variables that have any uncertainty associated with them. As a result the dose to the consumer is overestimated. Realistic CR values need to be developed to establish model parameters that will accurately reflect tissue burdens in fish and resulting dose rates to consumers. This report reviews and summarizes published literature on the uptake and distribution of stable and radioactive isotopes of 26 elements. Based on this review, we have made recommendations on CR values to be used for modeling the accumulation of radionuclides in fish. Our recommendations are compared with CR values reported in other publications. A generic discussion of abiotic and biotic factors that influence CR values is provided so that CR values may be adjusted based on site-specific characteristics of the fishes habitat. Recommended CR values for freshwater fish and for marine fish are listed. Although this report emphasizes radionuclides, it is …

GEOMETRICAL CONSIDERATIONS IN THE MEASUREMENT OF THE RATIO L/R IN THE SCATTERING OF POLARIZED NUCLEONS
A FORTRAN II program is described which is used to evaluate the effect of a spatially extended analyzer and detector on the measurement of the left- right asymmetry in the scattering of polarized particles. The initial scatterer is assumed to be a point source and the analyzer, second scatterer, and detector are treated as planes whose dimensions are adjustable as input data in the program. The calculation allows for any glven angular distribution of particle flux from the source if this distribution can be represented as a finite power series in the cosine of the angle of emission. A similar representation is used to describe the scattering properties of the analyzer. The integrals over the finite dimensions of the analyzer and detector are evaluated by a standard Newton- Cotes quadrature approximation for multidimensional integration. A discussion of this approximation as well as a listing of the FORTRAN program are included. (auth)

Fundamental studies of separation processes
Studies completed during the past year were: pressure and temperature effects on retention behavior of ion pairs, fractionation studies of sulfur isotopes in carbon disulfide, anomolous peak shapes obtained in gas chromatography using liquid crystal stationary phases in an electrostatic field, and the application of a new steric-exclusion packing for molecular-weight fractionation of petroleum crudes. Studies are continuing on the effects of the dead volume of a detector on the peak shape as a function of flow rate and molecular weight of the solute and on basic studies relating to the optimization of chromatographic parameters in supercritical fluid chromatography of large molecules, especially polymers. New studies that have been initiated include: the fractionation and identification of vanadium species in crude oils, the study of recycling chromatography at elevated pressures for difficult separations such as those involving isotopes, and the application of gradient techniques in liquid chromatography for the fractionation of polymers. Finally, equipment has been ordered for making solubility studies relating to the precipitation of compounds from geothermal brines, but experiments have not yet begun.

THEORETICAL STUDY OF OPTICAL PROPERTIES. PHOTON ABSORPTION COEFFICIENTS, OPACITIES, AND EQUATIONS OF STATE OF LIGHT ELEMENTS INCLUDING THE EFFECT OF LINES. Final Report. APPENDIX A: THERMODYNAMIC PROPERTIES AND MEAN OPACITIES
Photon absorption coefficients and mean opacities were calculated for hydrogen, beryllium, carbon, nitrogen, aluminum, and silicon over a temperature range froni l.5 to 34 ev and a density range from about l0/sup -1/g/cm/sup 3/ downward. Contributions to the absorption coefficient from free-free (inverse- bremsstrahlung), bound-free (photoelectric), and bound-bound (line-absorption) processes are included, as is Compton scattering. Certain thermodynamic properties are also given. An improved recipe for pressure ionization was derived which is approximately valid at nondegencrate densities for any ratio of Debye length to ion-sphere radius. Line absorption was evaluated using recent results from pressure-broadening theory and a representation of line series which is computationally as simple as the statistical method. The results show that lines increase the Rosseland mean opacity by a factor which can be nearly ten and which is insensitive to moderate changes in line widths. The code employed generated ionic energy levels internally by isoelectronic interpolation, and is immediately applicable to any- mixture of elements in which no ion has more than 14 bound electrons. The results of the calculations of thermodynamic properties and mean opacities are given in the tables in Appendix A, and the graphs of the monochromatic absorption coefficients are given in Appendix …

Results of hydrogen pellet injection into ISX-B
High speed pellet fueling experiments have been performed on the ISX-B device in a new regime characterized by large global density rise in both ohmic and neutral beam heated discharges. Hydrogen pellets of 1 mm in diameter were injected in the plasma midplane at velocities exceeding 1 km/s. In low temperature ohmic discharges, pellets penetrate beyond the magnetic axis, and in such cases a sharp decrease in ablation is observed as the pellet passes the plasma center. Density increases of approx. 300% have been observed without degrading plasma stability or confinement. Energy confinement time increases in agreement with the empirical scaling tau/sub E/ approx. n/sub e/ and central ion temperature increases as a result of improved ion-electron coupling. Laser-Thomson scattering and radiometer measurements indicate that the pellet interaction with the plasma is adiabatic. Penetration to r/a approx. 0.15 is optimal, in which case large amplitude sawtooth oscillations are observed and the density remains elevated. Gross plasma stability is dependent roughly on the amount of pellet penetration and can be correlated with the expected temporal evolution of the current density profile.

Palladium Catalyzed Coupling Reactions: Mechanism of Reductive Elimination. Progress Report, October 1, 1979-September 30, 1980. [Ethane Elimination]
The 1,1-reductive elimination of ethane from three cis-bis(phosphine)-dimethylpalladium complexes, L/sub 2/Pd(CH/sub 3/)/sub 2/ (L = PPh/sub 3/, PPh/sub 2/,CH/sub 3/ and L/sub 2/ = Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/), and three trans analogs (L = PPh/sub 3/, PPh/sub 2/CH/sub 3/ and L/sub 2/ = 2,11-bis(diphenylphosphinomethyl)benzo(c)phenanthrene (TRANSPHOS)) was carried out. The three cis complexes underwent reductive elimination in the presence of coordinating solvents (DMSO, DMF, and THF). The trans complexes which could isomerize to cis (L = PPh/sub 3/, PPh/sub 2/CH/sub 3/) did so in polar solvents and then underwent reductive elimination. TRANSPHOS dimethylpalladium would not undergo reductive elimination of ethane. The eliminations from the cis isomers were intramolecular and displayed first order kinetics. Although TRANSPHOS dimethylpalladium(II) would not undergo a 1,1-reductive elimination of ethane, the addition of CD/sub 3/I to a DMSO solution of this complex at 25/sup 0/C rapidly produced CD/sub 3/-CH/sub 3/, implicating a transient palladium(IV) intermediate. E- and Z-bromostyrylbis(diphenylmethylphosphine)palladium(0) react with methyl lithium in THF at ambient temperature to give the E- and Z- propenylbenzenes, respectively. At -78/sup 0/C, the intermediate E- and Z-styrylmethylbis(diphenylmethylphosphine)palladium(II) complexes (9a,b) can be isolated. On raising the temperature of solutions of 9a,b in THF, E- and Z-propenylbenzenes are produced. The reductive elimination …

Genes and gene expression: Localization, damage and control -- A multilevel and inter-disciplinary study
All projects are working toward a goal for describing the three dimensional nuclear topography in terms of relative spatial relationships among genes (specific DNA sequence). Methods are now being perfected to detect these genes, quantitatively and spatially, to perturb these genes specifically, and to measure the perturbation in order to assure specificity. We are developing methods to assay, after perturbation of the target DNA within living cells, whether or not only the target sequence are attacked while other sequences remain unharmed. We are now at the stage to do chemical gene modification or masking within living cells in a strictly sequence-specific manner. Soon, we will be able to study the function and the physical location of each gene in living cells with exquisite specificity. 25 refs., 15 figs.

Research guidance studies to assess gasoline from coal by methanol-to-gasoline and Sasol-type Fischer--Tropsch technologies
The primary purpose of this study is to provide a technical and economic comparison between the commercial Fischer-Tropsch technology and the new Mobil methanol-to-gasoline technology for the production of motor gasoline. Several technical sensitivity cases are also part of the study and will be included in the final report. Two conceptual plant complexes - Base Case I: Mobil Technology and Base Case II: Fischer-Tropsch Technology--have been developed. They are self-supporting, grass roots facilities assumed to be located in a Wyoming coal field. Plant size is equivalent to the proposed large commercial SNG plants. Except for the Mobil methanol conversion technology, all processes used are commercial. Co-production of all products has been assumed. Products have been upgraded to meet U.S. market specifications. A summary comparison of the two base cases shows that the Mobil technology is somewhat more efficient and more effective in producing gasoline. Moreover, the number of processing steps required is considerably fewer. All products meet the target specifications.

Shallow oil shale resources of the southern Uinta Basin, Utah
The shallow Green River Formation oil shales in the southern part of Utah's Uinta Basin are potentially developable by strip mining or by subsurface techniques which take advantage of limited overburden. The resource of potential shale oil represented by the shallow deposits is evaluated in detail from corehole oil-yield data. Cross-sections are constructed to readily correlatable stratigraphic units selected to represent resources in the shallow shale. To define each unit, the thickness, average oil yield, and oil resource of each unit in each core are calculated. Contour maps constructed from these data define the resource variation across the shallow resource. By measuring areas enclosed in each resource unit within the defined limit of 200 feet (61 meters) of overburden, the resource represented by the shallow oil shale is evaluated. The total resource is measured as 4.9 billion barrels (779.1 billion liters) of potential shale oil at depths less than 200 feet (61 meters). The rich zone incorporates the Mahogany bed, the best shallow oil-shale unit. This section, currently being exploited by Geokinetics, Inc., for in situ production of shale oil by horizontal combustion, represents 2.2 billion barrels (349.8 billion liters) of potential shale oil in place.

DIFFUSION OF Zr$sup 95$ IN BODY-CENTERED CUBIC IODIDE ZIRCONIUM
Chemically purifled Zr/sup 95/ was used in determining selfdiffusion coefficients in the body-centered cubic phase of iodide zirconium over the temperature range of 900 to 1750 deg C. In order to minimize effects of build-in of the daughter isotope Nb/sup 95/, all heat treatments were completed within 48 hr after the purification. The temperature dependence of the diffusion coefflcients could not be described by the usual Arrhenius-type equation. Instead, apparent values of the frequency factor D/sub o/ and the activation energy Q varied from 4.8 x 10/sup -6/ to 2.5 x 10/sup -2/ cm/sup 2//sec and 20700 to 46900 cal/mole, respectively, between the lower and upper extremities of the temperature range. Empirical treatment of the data indicated that Q is a linear function of temperature and that D/sub o/ varies with a power of the temperature. The data may be described in terms of the alpha to BETA transition temperature of 1136 deg K and the absolute temperature of the heat treatments by the following equation: D = 3 x 10/sup -6/ (T/1136)/sup 15.6/ exp (--19600 + 31(T -1136)/RT) cm/sup 2//sec.

Site development plan for Oak Ridge National Laboratory, Martin Marietta Energy Systems
The Oak Ridge National Laboratory (ORNL) is responsible for developing new and environmentally acceptable energy technologies that will offer the nation safe options for energy supply and efficient systems for energy use. Martin Marietta Energy Systems, Inc., (Energy Systems) operates ORNL under a management and operating contract. The purpose of the audit was to review and evaluate the effectiveness of site development planning activities at ORNL. A site development plan is a long-range master plan for the acquisition, development, utilization, and disposal of land and physical facilities at a specific US Department of Energy (DOE) facility. ORNL did not have a current site development plan and had not submitted updates to the old plan. This condition existed because the DOE Field Office, Oak Ridge (OR), and ORNL management had not implemented their responsibilities set forth in applicable DOE orders for site development planning. As a result, DOE had no assurance that ORNL real property holdings would be planned and developed economically and efficiently.

Preliminary flashing multiphase flow analysis with application to letdown valves in coal-conversion processes
As part of the Oak Ridge National Laboratory's technical support to large coal liquefaction projects, attempts have been made to (1) develop the methodology for characterizing and predicting multicomponent, multiphase, non-Newtonian flow behavior within letdown valves and devices, and (2) analyze the fluid flow in the entire letdown region of the process. An engineering model that can be used in the analysis of multicomponent, multiphase, flashing, flowing systems has been developed. A preliminary version of a user-oriented computer code for this model has been developed and is fully described.

Simulation of the carbon cycle in the ocean
A dual carbon-nitrogen biological model of the upper ocean has been developed, which has successfully allowed predictions of fluxes of carbon between atmosphere and the deep ocean to made. Regarding studying the carbon cycle in the ocean, the modelling has highlighted the need for a good understanding of the interactions between the carbon and nitrogen cycles, and also the importance of zooplankton grazing and levels of overwintering biological stocks. Problems have been encountered with the accuracy of prediction of the partial pressure of carbon dioxide in the surface ocean, and the sensitivity of the model to zooplankton parameters, and those parameters which effect overwintering stocks (e.g. mortality parameters). The model has recently been incorporated into a physical General Circulation Model of the Atlantic Ocean. Future work will involve assessing the performance of the biological model in General Circulation Models, and making necessary refinements in order to improve its predictive ability. 1 ref., 1 fig.

Use of the TRUEX process for the pretreatment of neutralized cladding removal waste (NCRW) sludge -- Results of FY 1990 studies
The goal of this process is to separate the transuranic elements from the bulk components so that the bulk components can be disposed of as low-level waste with only a small transuranic-containing fraction requiring geologic disposal. The pretreatment process examined here is the one indicated to be most promising in the initial studies. It involves dissolving the unwashed sludge in nitric acid and then using the TRUEX solvent extraction process to remove the transuranic elements from the bulk components of the waste. The areas identified in this work that need additional information are gradual precipitate formation as dissolved sludge solutions age, and formation of solid material when the dissolved sludge solution is contacted with the solvent used in the TRUEX process. 5 refs., 71 figs., 10 tabs.

Resource book: Decommissioning of contaminated facilities at Hanford
In 1942 Hanford was commissioned as a site for the production of weapons-grade plutonium. The years since have seen the construction and operation of several generations of plutonium-producing reactors, plants for the chemical processing of irradiated fuel elements, plutonium and uranium processing and fabrication plants, and other facilities. There has also been a diversification of the Hanford site with the building of new laboratories, a fission product encapsulation plant, improved high-level waste management facilities, the Fast Flux test facility, commercial power reactors and commercial solid waste disposal facilities. Obsolescence and changing requirements will result in the deactivation or retirement of buildings, waste storage tanks, waste burial grounds and liquid waste disposal sites which have become contaminated with varying levels of radionuclides. This manual was established as a written repository of information pertinent to decommissioning planning and operations at Hanford. The Resource Book contains, in several volumes, descriptive information of the Hanford Site and general discussions of several classes of contaminated facilities found at Hanford. Supplementing these discussions are appendices containing data sheets on individual contaminated facilities and sites at Hanford. Twelve appendices are provided, corresponding to the twelve classes into which the contaminated facilities at Hanford have been organized. Within …

Seismic analysis of reactor exhaust air filter compartment
The Filter Compartment (FC) in this analysis is a generic reactor airborne activity confinement filter compartment which possesses all the essential physical and mechanical properties of the Savannah River Site (SRS) confinement filters of Reactor Buildings K, L, and P. The filters belong to the Airborne Activity Confinement System (AACS). These filters absorb a significant amount of radioactive effluents from the exhausting air. The seismic excitation is input indirectly from the output of the seismic analysis of the 105 exhaust stack building in the form of floor response spectra. However, the 105 exhaust stack building was analyzed for seismic motions defined by free-field ground response spectra with a ZPA (Zero Period Acceleration) of 0.2G for all three orthogonal components of ground motion and a shape consistent with USNRC Regulatory Guide 1.60. Based upon equivalent dynamic analysis of the FC, DuPont engineers suggested modifications on the existing FC with heavy I-section beams (1). The scope of this phase I'' analysis, as requested by Seismic Engineering (2), is to carry out a scoping analysis'' of Frequency Analysis and Response Spectrum Analysis of the FC with DuPont suggested conceptual modifications. Our suggestion was that the existing FC without conceptual modifications be analyzed first. …
