Comparison of solar pond concepts for electrical power generation

Description: The objectives of this study were to: (1) Identify the various solar pond concepts for electric power generation, including but not limited to: (a) nonconvective salt gradient solar pond, (b) ponds with various plastic or other membranes at suitable locations to minimize or eliminate convection, (c) ponds which are totally or partially gelled to reduce or eliminate convection, and (d) shallow convecting ponds; (2) analyze and compare the performance of these various concepts; and (3) estimate t… more

Six phase rectifier digital computer simulation

Description: A digital computer program has been developed for the simulation of a six-pulse converter with a resistance-inductance load. The program calculates the time histories of the voltages and currents on both the ac and dc sides of the rectifier bridges. The grid delay angle is calculated in terms of the load current, supply voltage, and commutating reactance. The program is written in FORTRAN and is executable on the CDC7600 Plotted output of ten variables can be requested. This program is a prelim… more

Sealed storage cask concept. Cask closure concept evaluation. Interim report

Description: A program was conducted to evaluate four candidate storage cask closure configurations. Four major areas were evaluated to provide a basis for selection of an acceptable closure(s). These were: (1) weldability, (2) suitability of available nondestructive examination methods for determining weld soundness, (3) closure configuration structural soundness, and (4) economics. A relative ranking of each closure configuration was made using the study results. The corner weld configuration was ranked a… more

Gasification in pulverized coal flames. First quarterly progress report, July--September 1975

Description: This project is concerned with the production of power and synthesis gases from pulverized coal via suspension gasification. Specifically, the concentric jet and vortex gasifiers, with separation of oxidation and reduction zones, will be investigated. Gasifier performance will be correlated with internally measured temperature and concentration profiles. A suction pyrometer will be used to simultaneously measure temperature and gas concentrations. Rapid species analysis will be provided by a UT… more

Structural analysis of TFTR vacuum vessel bellows and bellows cover sections

Description: A structural evaluation of the bellows and bellows cover sections was undertaken in order to confirm the structural integrity of these TFTR vacuum vessel components in the prescribed operating environment. The evaluations investigate component stability, stress, and deflection behavior. The products of this investigation appearing in this report include; (1) Structural verification of the vacuum bellows as currently defined in an operating environment of one atmosphere external pressure and 93/… more

Structural analysis of TFTR toroidal field coil conceptual design

Description: The conceptual design evaluation of the V-shaped toroidal field coils on the Tokamak Fusion Test Reactor has been performed by detailed structural analysis with the finite element method. The innovation provided by this design and verified in this work is the capability to support toroidal field loads while simultaneously performing the function of twist restraint against the device axial torques resulting from the vertical field loads. The evaluations made for the conceptual design provide pre… more

Collection of preliminary thermal and structural calculations for TFTR components

Description: Many scoping type thermal/hydraulic and structural calculations have been performed for the TFTR component conceptual designs. Five analyses are still applicable to the current October conceptual design. The analyses are for the vacuum vessel wall temperature, neutral beam calorimeter thermal response, the discharge time of the tritium line, estimate of air leakage in the TFTR Test Cell, and maximum allowable TF coil temperature. The methods of analysis and the results are presented in this rep… more

TFTR generator load assessment

Description: Typical experimental load demands on the TFTR generators are illustrated based on the electrical characteristics of the field coils, the coil leads, the main bus work, the various auxiliary bus work, the rectifiers, and transformers. The generator MW capacities are shown to be adequate for the proposed experimental operations with allowances made for variations in the final designs. The generator MVA capacities are shown to be adequate provided portions of the TF and EF rectifiers are freewheel… more

Structural analysis and optimization procedure of the TFTR device substructure

Description: A structural evaluation of the TFTR device substructure is performed in order to verify the feasibility of the proposed design concept as well as to establish a design optimization procedure for minimizing the material and fabrication cost of the substructure members. A preliminary evaluation of the seismic capability is also presented. The design concept on which the analysis is based is consistent with that described in the Conceptual Design Status Briefing report dated June 18, 1975

Thermal analysis of the TFTR vacuum vessel wall protective plate

Description: The TFTR vacuum vessel is to be protected with tungsten plates from the effects of neutral beam impingement. A thermal analysis is performed to determine the maximum allowable beam intensity (power per unit area) under normal and faulted operating conditions. In order to permit a faulted pulse, or unattenuated injection, to occur after normal pulse series, the maximum neutral beam energy flux should be below 10 kW/cm/sup 2/ depending on the beam design configuration, to prevent the melting of t… more

Polarizability of the low frequency excitations in disordered solids. [Polymethylmethacrylate]

Description: An attempt to find manifestations of an electric dipole moment associated with the low-temperature thermal properties of glasses has enabled the setting of very low limits for GeO/sub 2/ and PMMA, 0.06 and 0.16 Debye respectively. Measurements of the temperature dependence of the dielectric constant and the electric field dependence of the thermal conductivity of SiO/sub 2/ in conjunction with dielectric measurements by Schickfus et al. has pinned down some of the features of a tunneling system… more
