MIT LMFBR blanket physics project progress report No. 7, July 1, 1975--September 30, 1976 (open access)

MIT LMFBR blanket physics project progress report No. 7, July 1, 1975--September 30, 1976

Work during the period was devoted primarily to a range of analytical/numerical investigations, including evaluation of means to improve external blanket designs, beneficial attributes of the use of internal blankets, improved methods for the calculation of heterogeneous self-shielding and parametric studies of calculated spectral indices. Experimental work included measurements of the ratio of U-238 captures to U-235 fissions in a standard blanket mockup, and completion of development work on the radiophotoluminescent readout of LiF thermoluminescent detectors. The most significant findings were that there is very little prospect for substantial improvement in the breeding performance of external blankets, but internal blankets continue to show promise, particularly if they are used in such a way as to increase the volume fraction of fuel inside the core envelope. An improved equivalence theorem was developed which may allow use of fast reactor methods to calculate heterogeneously self-shielded cross sections in both fast and thermal reactors.

Liquid Metal Engineering Center (LMEC) annual technical progress report, January-December 1975 (open access)

Liquid Metal Engineering Center (LMEC) annual technical progress report, January-December 1975

During operation of the prototype FFTF sodium pump, it is necessary to know the position of the pump shaft relative to the sodium-lubricated hydrostatic bearing journals. Performance of the Kaman proximity measurement system was known to be affected by the type of media between the gap to be measured. Since Kaman Sciences Corp. did not have liquid sodium testing capabilities, LMEC was requested to evaluate a spare prototype system. Determination of the sodium performance characteristics of the Kaman proximity systems was a necessary requisite for use of four prototype systems in the FFTF prototype pump test program.

Study of reduction of accessory horsepower requirements. Sixth quarterly progress report (open access)

Study of reduction of accessory horsepower requirements. Sixth quarterly progress report

The objective of this program is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The present Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: hydromechanical and mechanical variable-ratio belt drive fabrications completed; compact vehicle fuel economy analysis completed; initial engine check runs for both drive systems were completed; mechanical drive system development and performance mapping was initiated; hydromechanical drive system development tests and modifications were initiated; the hydromechanical drive system installation into the test vehicle was completed; the engine/dynamometer test rig, including accessory load simulators, was completed; and the basic test vehicle instrumentation was completed.

S/sup 3/ Financial Projection Model: preliminary user's manual and system overview (open access)

S/sup 3/ Financial Projection Model: preliminary user's manual and system overview

The S/sup 3/ Financial Projection Model is an effort undertaken to construct a pipeline economic model in order to satisfy the requirements of the US ERDA program: Energy Study of Pipeline Transportation System. A brief outline of this process is described in Appendix A, Background on the S/sup 3/ Development of a Pipeline Economic Model. A general overview of the model is presented first to indicate the rationale underlying the model and to show the linkages between the various submodels. An understanding of the basic accounting definitions and self-evident relationships between line items in the general financial accounting reports is a prerequisite for the effective application of the model. Particular attention has been paid in this system description to defining the methods of calculations utilized by the model and to describing the optional capital investment planning techniques that may be exercised with the model. The mathematical relationships underlying various planning techniques are defined and the methods for applying these techniques are discussed with illustrations and sample input data specifications. Decision tables are used to show complex decision rules applied within the model to determine the logical flow of a particular computational routine. The complete set of source data and model …

Evaluation of the fuel-conservation potential of truck aerodynamic-drag-reduction devices (open access)

Evaluation of the fuel-conservation potential of truck aerodynamic-drag-reduction devices

A study of commercially available and prototype aerodynamic drag reduction devices which can be retrofitted onto this nation's trucks to achieve significant fuel savings by 1980 was conducted. The results of the study are presented in seven sections. An overview of the basic study results is given in the Summary Section, and a brief introduction to the general nature of the truck drag problem and the study scope is contained in Section 1. Section 2 provides a more detailed discussion of the aerodynamic drag problem and the characteristics of specific retrofit aerodynamic drag reduction devices which are in the production or prototype status. The results of a survey of fleet owners utilizing aerodynamic drag reduction devices and their experience with regard to fuel savings and operational factors are given in Section 3. Section 4 contains the results of economic analyses made to determine the cost-benefit effects of drag reduction devices. An analysis of the US truck population to which such drag reduction devices may be applicable and the fuel savings potential attendant to their use is given in Section 5. The significant elements of a program structured to encourage the utilization of aerodynamic drag reduction devices on trucks are defined …

Mathematical model for the preliminary analysis of dual-mode space nuclear fission solid core power and propulsion systems, NUROC3A. AMS report No. 1239a (open access)

Mathematical model for the preliminary analysis of dual-mode space nuclear fission solid core power and propulsion systems, NUROC3A. AMS report No. 1239a

The three-volume report describes a dual-mode nuclear space power and propulsion system concept that employs an advanced solid-core nuclear fission reactor coupled via heat pipes to one of several electric power conversion systems. Such a concept could be particularly useful for missions which require both relatively high acceleration (e.g., for planetocentric maneuvers) and high performance at low acceleration (e.g., on heliocentric trajectories or for trajectory shaping). The first volume develops the mathematical model of the system.

Similarity solutions for convection of groundwater adjacent to horizontal impermeable surfaces with axisymmetric temperature distribution. Technical report No. 14 (open access)

Similarity solutions for convection of groundwater adjacent to horizontal impermeable surfaces with axisymmetric temperature distribution. Technical report No. 14

The axisymmetric buoyancy-induced groundwater flow adjacent to horizontal impermeable surfaces with wall temperature being a power function of radius is discussed in this paper. With the boundary layer simplifications, the governing non-linear partial differential equations can be transformed into a coupled pair of non-linear ordinary differential equations with two-point boundary conditions that can be integrated numerically by established techniques. Simple algebraic expressions for boundary layer thickness and heat transfer rate are obtained. Applications to free convective flow in a liquid-dominated geothermal system at high Rayleigh number are discussed.
