This report examines the implications of thee Clean Air Act Amendments of 1977 concerned with provisions designed to prevent the significant deterioration of air quality in areas of the nation where the ambient air is cleaner than the minimum levels required to meet National Ambient Air Quality Standards (NAAQS). The legislation will affect the economic competitiveness of alternative fuel cycles for the generation of power and will have implications for the future siting of all new major sources of emissions. This paper examines the potential effects of Prevention of Significant Deterioration (PSD) legislation on energy technologies and industrial facilities and, in particular, the possible effects on energy research and development programs of the Department of Energy (DOE).

This report outlines the major effects of OPEC countries raising the effective oil prices from $3.45 a barrel to $9 a barrel in 1973. The main economic problems the author mentions are inflation, domestic demand, and acute balance-of-payments. In addition, this report outlines policy options for the United States and other industrial countries.

The Theoretical EOS Group develops theoretical techniques for describing material properties under extreme conditions and constructs equation-of-state (EOS) tables for specific applications. Work this quarter concentrated on a Li equation of state, equation of state for equilibrium plasma, improved ion corrections to the Thomas--Fermi--Kirzhnitz theory, and theoretical estimates of high-pressure melting in metals. The Experimental Physics Group investigates properties of materials at extreme conditions of pressure and temperature, and develops new experimental techniques. Effort this quarter concerned the following: parabolic projectile distortion in the two-state light-gas gun, construction of a ballistic range for long-rod penetrators, thermodynamics and sound velocities in liquid metals, isobaric expansion measurements in Pt, and calculation of the velocity--mass profile of a jet produced by a shaped charge. Code development was concentrated on the PELE code, a multimaterial, multiphase, explicit finite-difference Eulerian code for pool suppression dynamics of a hypothetical loss-of-coolant accident in a nuclear reactor. Activities of the Fluid Dynamics Group were directed toward development of a code to compute the equations of state and transport properties of liquid metals (e.g. Li) and partially ionized dense plasmas, jet stability in the Li reactor system, and the study and problem application of fluid dynamic turbulence theory. 19 …

The maximum fluid forces acting on the LOFT DTT Rake Assembly during steady state and LOCE modes of operation, were estimated and presented for the 5-inch equivalent break flow area. A total of six loading mechanisms for each of the two modes of operation were identified. The most significant mechanisms were determined and the resulting loads and frequencies were estimated. The significant loading mechanisms were the Karman vortex-induced alternating lift forces, the steady lift forces due to pipe elbow secondary flows, and the steady drag forces.

Highlights of technical progress during January 1978 are presented for sixteen separate program activities which comprise the ORNL research program for the Office of Nuclear Regulatory Research's Division of Reactor Safety Research.

Literature on ways for saving energy by retrofitting single family homes was surveyed, and each energy conservation option is evaluated for economic desirability. The options considered include the prevention of heat losses by reducing air infiltration and by increasing thermal insulation, optimizing furnace operation, lowering space and water heater temperatures, flue gas heat recovery, and controlling hot water flow. The cost and payback period is given for each option. (LCL)

The numeric and text processor of the MASTER CONTROL (MCP) data-base-management system permits the user to define fields and arrays that are functionally dependent on the data retained in a data base. This allows the storage of only the essential and unique information and data, and the calculation of derivable quantities as required. The derived quantity can be expressed as an arithmetic expression, that is, a functional relationship. Functions can be multiply subscripted and can be embedded within other functions at up to 58 levels. They can be stored either semi-permanently in a repertoire of functional relations, or they can be defined interactively from a terminal and used immediately for searching on the derived value. The processor also permits the conversion of literal strings into numbers, and vice versa. In addition, the user can define dictionaries that allow the expansion of keyed sentinels associated with records in the data base into fully descriptive expressions. This option can be used for cost-effective searching and data compaction. The functional definitions are reduced to Polish notation and stored in a disk file from which they are either retrieved on demand and evaluated according to the data of records specified or used in any …

During 1976, new Mirror Program plans have been laid out to take into account the significant advances during the last 18 months. The program is now focused on two new mirror concepts, field reversal and the tandem mirror, that can obtain high Q, defined as the ratio of fusion power output to the neutral-beam power injected to sustain the reaction. Theoretically, both concepts can attain Q = 5 or more, as compared to Q = 1 in previous mirror designs. Experimental planning for the next 5 years is complete in broad outline, and we are turning attention to what additional steps are necessary to reach our long-range goal of an experimental mirror reactor operating by 1990. Highlights of the events that have led to the above circumstance are listed, and experimental program plans are outlined.

Corrosion of uranium in O/sub 2/ or H/sub 2/O atmospheres can be inhibited by first oxidizing the surface and then exposing it to organic vapors at temperatures near 400/sup 0/C. There is evidence that a polymeric material is formed on the surface and that it may be responsible for the corrosion inhibition. Polymer coatings can also be prepared using an RF discharge. This paper describes experiments in which uranium surfaces were exposed to an RF discharge and then evaluated as to their corrosion resistance and surface characteristics. Various plasma gases were used and in each case corrosion inhibition resulted. Samples for corrosion tests and ESCA/Auger examinations were prepared at the same time. The ESCA spectra reveal the formation of hydroxyl groups on uranium surfaces exposed to the RF discharges. Comparisons with corrosion tests suggest that a low surface hydroxyl concentration is associated with a low corrosion rate. The experiments reveal variations in both surface composition and corrosion reactivity which are related to the plasma gas used. These results are discussed in terms of possible reactions occurring between uranium and the RF plasma.

Electrical noise interference in low-level (approximately 50 ..mu..V), wide band (approximately 15 MHz) flux monitoring systems applied to nuclear reactor control causes safety and reliability problems. Others have shown that one predominant source of noise interference is conduction of currents in instrument cable shields and building conduits. Since these currents produce noise that is similar to signals produced by nuclear detectors, such noise interference reduces the ability of a reactor instrumentation system to determine the condition of a reactor. Model equations of ground noise interference were derived for a system model consisting of a sensor, coaxial cable, and an amplifier. These equations describe the effect of ground impedance, sensor impedance, transfer impedance, and connector resistance on both low-frequency (less than 100 kHz) and high-frequency (greater than 100 kHz) ground noise interference. Other model equations were derived for a system with a coaxial balun (a flexible coaxial cable wound around a ferrite core) added between the sensor and the sensor amplifier input. Analysis of the model equations reveals the effects of ground noise currents on instrumentation systems and the conditions for minimizing ground interference.
