Established uses of enriched isotopes in the environmental field were surveyed to determine future trends in isotope needs. Based on established isotope uses, on the projected increase in the pollution problem, and on the apparent social and economic pressure for pollution abatement, a significant demand for enriched isotopes appears to be developing for the assessment and control of air, water, and soil pollutants. Isotopic techniques will be used in combination with conventional methods of detection and measurement, such as gas chromatography, x-ray fluorescence, and atomic absorption. Recent advances in economical isotope separation methods, instrumentation, and methodology promise to place isotopic technology within the reach of most research and industrial institutions. Increased application of isotope techniques appears most likely to occur in areas where data are needed to characterize the movement, behavior, and fate of pollutants in the environment.

A program was conducted for the definition and demonstration of acceptable waste packages for defense transuranic waste for interim storage and terminal isolation. During FY-1977, a Contractor Questionnaire was used to gather pertinent data and to assess contractor concerns. This information was integrated into basic application data in the form of a checklist. Conceptual Container Design Specifications were developed by analyzing and evaluating the application data against Federal Regulations and interim/terminal storage constraints.

SRI International has conducted research on the upgrading of computerized thermo-hydro code calculations and the synthesis of energetic materials. This project comprised four tasks, as follows: Task A included: (1) formulating routines for inverting the P = P(T,V) and V = V(T,P) equations of state when isotherms exhibit a van der Waals' loop; (2) incorporating these routines into the TIGER code so V and T can be used as independent variables in computing thermodynamic functions of liquids exhibiting a van der Waals' loop; (3) using these routines to incorporate into TIGER the prototype equation of state for liquids formulated at LLL by Dr. E.L. Lee; and (4) modifying TIGER routines to perform thermodynamic calculations when the concentrations of the gaseous species become zero. In Task B, a homopolymer of fluorodinitroethyl vinyl ether was obtained as a white, cotton-like material by bulk cationic polymerization. Work was begun on solution polymerization of fluorodinitroethyl vinyl ether. During Task C, studies were conducted on the synthesis of energetic compounds, especially hexanitrobenzene (HNB). The following areas were investigated: (1) nitration of phloroglucinol trioxime; (2) reaction of nitroaromatics with hydroxylamine; (3) oxidation of triaminotrinitrobenzene (TATB) with nitric acid; (4) oxidations with trifluoroperacetic acid, (5) oxidations with …

Development of a risk-analysis methodology for inclusion in the Threshold Screening Model used by the Buildings and Community Systems Division for the purpose of evaluating projects that are candidates for funding by that division is proposed. The contract includes a review of the pertinent literature, discussions with individuals in industry, development of evaluation criteria, development and test of alternative approaches, evaluation of results, and preparation of a final report. The following are described: management structure; the technical approach; the work breakdown structure; management control; government-owned property, facilities, and material; and test and security plans.

A methodology, distributed by DOE, may be used as a potential tool for the utility industry to assess and evaluate productivity and reliability problems of existing and future units. The model can be used to assess the impact of an improvement project or corrective action on unit productivity parameters such as heat rate, capacity factor, availability, or equivalent availability. The methodology analyzes: the effect of component redundancy on unit equivalent availability; the effect of component reliability on unit equivalent availability; and a component's outage trend to project the component's future outage rate. The first purpose of this study is to illustrate for the utilities how to apply the methodology. Thus, this report contains the analysis performed by applying the methodology at three units of Illinois power plants. The units evaluated were Wood River 5, Quad Cities 1, and Quad Cities 2. A total of 8 improvement projects were evaluated and all outage data and equations used are included in order to facilitate utility reproduction of the given results. The second purpose is to evaluate the methodology as a useful tool for individual utilities; a number of modifications are suggested.

The guidebook is a practitioner-oriented supplement to standard texts in optics and mechanical engineering. It reflects practical experience with the oftentimes troublesome aspects of effectively integrating optical components with mechanical hardware. Accordingly, its focus is on the techniques, assumptions, and levels of design sophistication needed for a wide variety of sizes and optical surface quality levels. It is intended to be a primer for engineers, designers, and draftsmen already familiar with some of the problems encountered in mounting optical components and who are responsible for developing components for high-energy laser systems.

Automation of the Jarrell-Ash 3.4-Meter Ebert direct-reading emission spectrometer with digital scaler readout is described. The readout is interfaced to a Data General NOVA 840 minicomputer. The automation code consists of BASIC language programs for interactive routines, data processing, and report generation. Call statements within the BASIC programs invoke assembly language routines for real-time data acquisition and control. In addition, the automation objectives as well as the spectrometer-computer system functions, coding, and operating instructions are presented.

The program has progressed to the final assembly of the recharging system on the Czochralski furnace. All components are in place and functional, and the modified furnace is being tested prior to the start of process development. The feasibility of a 100 kg continuous growth process has been demonstrated by a recharge simulation comprising six melt/pull cycles with a single 20 kg charge; the total body length was 249 cm (98 inch) with a calculated mass of 106 kg. Growth conditions were maintained for 67 hours with neither machine malfunction, excessive SiO accumulation, nor crucible failure. Examination of the crucibles revealed that devitrification and deformation are primarily responsible for the decrease in the wall thickness, which reaches approximately 50% of the minimum starting thickness at the locus of maximum attack--the corner radius. The crucibles also showed no adherence to the residual charge, which may be due to the surface structure produced by the long-term exposure of the silica to molten silicon.
