In working with statistical health and environmental data assumed to be lognormal, the data must be transformed back to normal data before correlations are taken. Recommendations for other measures of correlation are given. (PCS)

An injector design for the Reference Mirror Reactor is described which uses negative ions created by charge-exchange in a cesium vapor cell and neutralized by photodetachment. Some of the innovations discussed include a continuously operating cathode for an LBL/LLL ion source, a negative ion beam line with cooled grids, a high voltage accelerator configuration with insulators shielded from the neutron and gamma flux, and cryopanels which continuously cycle between pumping and outgassing modes.

A Faraday cup design for a 1 mA.cm/sup -2/ 100-keV, light-ion-beam measurement in background plasma is proposed. Features of this shielded, three-grid structure with deep target are described, and a mechanical draft is included. In the appendix, we reference and survey results of experiments reporting the number and energy range of secondary electrons and back-scattered ions originating on various metal surfaces bombarded with approximately 100-keV hydrogen and deuterium ions. Choice of target and grid materials in cup assembly follow from this survey.

A summary is presented of work leading to the design of a subcritical facility for the study of fast reactor blankets. Included are activities related to fuel acquisition, design of the facility, and experiment planning.

An unbounded horizontal fluid layer in a porous medium with an internal heat source and uniformly heated from below was studied. The layer is in the gravitational field. Linear theory predicts that the disturbances of infinitesimal amplitude will start to grow when the Rayleigh number exceeds its critical value. These disturbances do not grow without limit; but by advecting heat and momentum, the distrurbances alter their forms to achieve a finite amplitude. Just like infinitesimal amplitude disturbances the degenercies of possible solutions persist for finite amplitude solutions. This study evaluates the stability of these various forms of solutions. The small parameter method of Poincare is used to treat the problem in successive order.

The status of the effort to apply MULTI-FOIL thermal insulation in an effective manner to the Ground Development System (GDS) is reviewed. Heat loss measurements made on cylindrical and elbow heat sources using ''Tape'' and ''Conventional'' MULTI-FOIL indicate that the thermal losses are comparable on a per layer basis. However, use of the tape incurs a weight penalty, per layer, of about 20 percent. The effective thermal emissivity of the nickel layer/zirconia powder MULTI-FOIL is approximately 0.32. Parametric studies of GDS insulation losses (using a computer program developed for this purpose) indicate: (1) that the Heat Source Assembly (HSA) heat losses are a major fraction of the total and (2) that a significant reduction in heat loss is possible by optimizing the distribution of foil layers. A meltdown test of a miniature HSA configuration suggests that additional MULTI-FOIL layers can be safety added to the HSA insulation. Test data indicate that ''Electroformed'' MULTI-FOIL insulation assemblies (as a consequence of decreased edge loss and lower foil emissivity) are approximately four times as effective as either ''Conventional'' or ''Tape'' MULTI-FOIL packages on a weight basis. Preliminary GDS insulation design and planning have been completed.

Some estimates of the shape of C/sub s/ ion and C/sub s/ atom interaction potentials suggest that the C/sup +//sub s/ + C/sup +//sub s/ charge transfer cross section may be less than 10/sup -15/ cm/sup 2/.

The Safety Analysis Report for Packaging demonstrates that the neutron shipping cask can safely transport, in solid or powder form, all isotopes of uranium, plutonium, americium, curium, berkelium, californium, einsteinium, and fermium. The shipping cask and its contents are described. It also evaluates transport conditions, structural parameters (e.g., load resistance, pressure and impact effects, lifting and tiedown devices), and shielding. Finally, it discusses compliance with Chapter 0529 of the Energy Research and Development Administration Manual.

''SOCKITTOME'' was the name given a collection of routines which processed data of the form y = f(x). This collection consisted of a ''public'' controller (SOCKITTOME) and controllees stored in a political library file to be called up (and disposed of) by the controller. Later, it was decided to put routines capable of processing z = f(x,y) image data under the control of SOCKITTOME, and to rewrite them so that they could be as general and useful as possible. The disk file format was also revised so that it, too, could be as general as desired. The bulk of this report is devoted to a description of the new SOCKITTOME image routines and their usage. (RWR)

This program was written to be used as a subroutine. The program determines the thermodynamic properties of water given any of the following pairs of knowns to define a thermodynamic state: pressure and entropy, pressure and enthalpy, pressure and quality, temperature and pressure, or temperature and quality. These five pairs of knowns allow the user to evaluate any thermodynamic cycle using water, as a working fluid. The basic equations came from Keenan, Keyes, Hill and Moore, Steam Tables, John Wiley and Sons, 1969. This report includes a complete derivation of equations, program listing, program symbol description, a complete set of flow charts and a sample steam turbine calculation.

A detector system combining the good time resolution and low dead time to PWC's and the good space resolution of drift chambers is proposed to upgrade the MPS and for future use in Isabelle spectrometers. Central to this detector is the development of two integrated electronic circuit systems. The detectors are described with special emphasis on the electronic systems. The detector system proposed will be capable of handling particle flux rates typical of conventional PWC's yet providing a spacial resolution of 100 ..mu..m. Another advantage is that a large area detector of such performance will become technically feasible as well as economically viable.

The Mini-BRU turbine plenum and nozzle assembly in superalloy and the currently available L.A. heat exchanger have been examined for the BIPS workhorse system. Waspaloy can be used as the material of construction for the plenum and nozzle assembly. The L.A. heat exchanger can be utilized in the workhorse system with recommended modification.

Promising new techniques for making quantitative measurements of plutonium require highly precise values of the gamma-ray energies and intensities for the isotopes involved. Using high isotopic purity sources and state of the art Ge(Li) detectors, we have reevaluated the energies and absolute emission probabilities of the gamma rays following the decay of /sup 237/U, /sup 238/, /sup 239/, /sup 240/, /sup 241/Pu, and /sup 241/Am.

Program NAES (Nonlinear Algebraic Equation Solver) is a Fortran IV program used to solve the vector equation f(x) = 0 for x. Two areas where Program NAES has proved to be useful are the solution for initial conditions and/or set points of complex systems of differential equations and the identification of system parameters from steady-state equations and steady-state data. Program SS (State Space) is a Fortran IV program used to solve a system of first-order, ordinary differential equations with a minimum of specialized coding. Program SS automatically provides a tabular listing and line-printer plots of the outputs. In addition, provisions are made to perform one-time preintegration calculations, read specialized input data, establish specialized output labels, handle piecewise continuous f(x(t),t), make x--y plots of output variables, and record the minima/maxima of specified variables. Subroutines were written to provide delay, level detection with hysteresis, and solutions to implicit equations. 26 figures, 1 table.

Data were obtained for the surface heat transfer coefficient of uranium and the alloys of uranium-0.75 wt percent titanium, uranium-6 wt percent niobium, and uranium-7.5 wt percent niobium-2.5 wt percent zirconium. Samples were heated to 850/sup 0/C in both a molten salt bath and an argon-purged air furnace, then the samples were cooled in air. Surface heat transfer coefficients were calculated from the experimental data for both heating and cooling of the metals. 4 fig, 4 tables.

Some multivariate statistical tests are reviewed that could be used to measure relationships between two sets of measurements on air pollutants when both sets are affected by the weather. The tests are easily carried out using standard statistical packages, and the results may be used to indicate whether it is worthwhile to proceed or to develop more delicate procedures.

Thermogravimetric analysis on cesium aluminosilicates was performed. Pollucite, CsAlSi/sub 2/O/sub 6/, appears to have more than adequate thermal stability for Cs fixation in supercalcine. The possibility of leaving Ru as RuO/sub 2/ during supercalcine crystallization is being assessed. The apatite solid solution (A/sub ss/) phases used in supercalcine phase formation models have been easily prepared as pure phases. Use of Ca instead of Sr as an alkaline earth additive yields a more stable A/sub ss/ phase. Weight ratios have been optimized for two firing temperatures in terms of soxhlet leachability. However, this is not the preferred approach to supercalcine consolidation. The phase formation models developed for PW-4b-type wastes were routinely applied to PW-7, in spite of several significant composition differences in the latter. Uranium oxide remains as a fluorite structure oxide after supercalcine crystallization, but it does seem to have incorporated either or both CeO/sub 2/ or ZrO/sub 2/. Characterization of this F/sub ss/ phase will require further study. Based on observations during several complex compatibility studies, it appears that good overall thermal stability at as high as 1200/sup 0/C might be attainable for nepheline based supercalcine formulations. A thorough literature review of the oxide crystal chemistry of Te has …

The criteria, replace HW-83959 and apply to containers constructed specifically for the containment of beta-gamma radioactively contaminated waste removed from an area controlled by radiation work procedures, transported across an uncontrolled area where there is risk of a radiation release to the environs, and buried in an approved radioactive waste burial ground.

A cursory review of literature dealing with various separatory processes involved in the handling of high-level liquid nuclear waste discloses that, for the most part, discussion centers on separation procedures and methodology for handling the resulting fractions, particularly the actinide wastes. There appears to be relatively little discussion on the incentives or motivations for performing these separations in the first place. Discussion is often limited to the assumption that we must separate out ''long-term'' from our ''short-term'' management problems. This paper deals with that assumption and devotes primary attention to the question of ''why partition waste'' rather than the question of ''how to partition waste'' or ''what to do with the segregated waste.''

The ARGUS laser facility has been developed to achieve significant laser fusion milestones; high density (greater than 10 g/cm/sup 3/) implosions, high temperature (greater than 10 KeV) implosions, and high yield from advanced target designs. The ARGUS laser, central to this facility is a twin-beam, 20 cm output aperture, Nd:glass solid state laser capable of delivering greater than 3 TW of power to laser fusion targets. At the present time, ARGUS is fully operational, and has produced up to 10/sup 9/ neutrons in selected target irradiation experiments. The performance of this facility is described.

A summary of current activities in applied and computational mathematics at the Lawrence Livermore Laboratory is given. It is evident from the survey that there is a very broad spectrum of research and development in this area of mathematics. However, only a small percentage of the total effort is directly involved with fundamental research. The Laboratory is advised to adopt a formal policy to establish and support a research program in applied and computational mathematics. Coordination of related efforts is needed, and steps toward this are recommended. In addition, a study of interactions between mathematical methods and computer architectures is necessary for the Laboratory's ever-increasing requirement for computational capability. 5 figures, 3 tables.

In differential pumping, the pumping speed has in the past been controlled by the size of the orifice between the vacuum chamber and the diffusion pump. This fixed orifice is usually in the valve gate of a high-vacuum valve (or in a baffle plate). To change the pumping speed, then, the valve must be removed and another valve with an orifice of a different size must be inserted. This process is time consuming and risks contamination of the system, which would require another pumpdown and bakeout. A simple shutter that controls pumping speed without requiring any change in components has been developed. The shutter consists of 20 leaves arranged as an iris that opens to a 6-in.-dia orifice or closes to 0.25 in. The shutter consists of a mounting ring, the leaves, a drive ring, and a drive gear. Each leaf is stainless steel with a pivot pin at one end and an offset pin at the other. The leaves are placed in the mounting ring and the drive ring and the drive gear are attached. Rotating the drive gear moves the leaves and changes the orifice size. One of the shutters has been used successfully with a 4-in. diffusion …

A status report of microinstability as it applies to 2XIIB and MX theory for mirror machines is presented. It is shown that quasilinear computations reproduce many of the parameters observed in the 2XIIB experiment. In regard to large mirror machines, there are presented detailed calculations of the linear theory of the drift cyclotron loss-cone mode, with inhomogeneous geometry and nonlinear diffusive effects. Further, the stability of a mirror machine to the Alfven ion-cyclotron instability is assessed, and the Baldwin- Callen diffusion is estimated for a spatially varying plasma. (auth)
