Some estimates of mirror plasma startup by neutral beam heating of pellet and gas cloud targets

Description: Hot plasma buildup by neutral beam injection into an initially cold solid or gaseous target is found to be conceivable in large mirror machine experiments such as 2XIIB or MFTF. A simple analysis shows that existing neutral beam intensities are sufficient to ablate suitable targets to form a gas or vapor cloud. An approximate rate equation model is used to follow the subsequent processes of ionization, heating, and hot plasma formation. Solutions of these rate equations are obtained by means of… more

Solar system installation at Louisville, Kentucky (final report)

Description: A contract was awarded in June 1976 for the installation of a solar space heating and domestic hot water system at 2400 Watteroon Trail, Louisville, Kentucky. The overall philosophy used was to install both a liquid and a hot air system retrofitted to the existing office and combined warehouse building. The 1080 sq ft office space is heated first and excess heat is dumped into the warehouse. The two systems offered a unique opportunity to measure the performance and compare results of both air … more

OTEC platform configuration and integration. Volume III. Project Plan. Final report

Description: The Spar and Sphere offshore platforms are feasible concepts for the demonstration of a near full size OTEC plant to determine its validity and to gather data for use in the construction, design and operation of commercial OTEC plants. A hull size suitable to support a 100 MWe net output plant was chosen. Either 50, 25 or 12.5 MWe power modules could be used. Selection of 50 MWe modules would permit the testing of equipment recommended for the commercial plant. The use of 25 MWe modules would p… more

OTEC platform configuration and integration. Volume II. Technical concept. Final report

Description: The configuration, integration, and evaluation studies performed in the first phase of this contract resulted in a ranking of the most feasible platform candidates for commercial OTEC applications. On the basis of the results obtained from three individual contractors performing the same study, the Department of Energy made selections of two platform hulls for each contractor for conceptual designs. For Phase-II studies, M. Rosenblatt and Son, Inc. (MR and S) project team was given the SPAR and… more

Tables and graphs of photon-interaction cross sections from 0. 1 keV to 100 MeV derived from the LLL Evaluated-Nuclear-Data Library

Description: Energy-dependent evaluated photon interaction cross sections and related parameters are presented for elements H through Cf (Z = 1 to 98). Data are given over the energy range from 0.1 keV to 100 MeV. The related parameters include form factors and average energy deposits per collision (with and without fluorescence). Fluorescence information is given for all atomic shells that can emit a photon with a kinetic energy of 0.1 keV or more. In addition, the following macroscopic properties are give… more

Stress analysis of the LOFT core barrel for LOCA + SSE loads

Description: The results of a dynamic analysis of the LOFT Reactor Core Barrel for faulted conditions are presented in this report. Loading conditions considered were seismic accelerations resulting from a Safe Shutdown Earthquake (SSE) and pressure loadings from both a hot leg and a cold leg Loss-of-Coolant Accident (LOCA) break. Maximum stresses in the core barrel, resulting from these conditions, are presented with comparisons to Code allowables. Stresses were found to be within allowables for the faulte… more

Comments: Energy Resources Conservation and Development Commisssion (ERCDC) Draft Staff Report - Geothermal

Description: My major impression of the Staff Draft ''Geothermal Policy Option Paper...'' is that notwithstanding repeated statements that geothermal development is to be encouraged by streamlining the regulatory siting process, the ERCDC is trying to confer on itself jurisdiction over the exploratory development of the resource; thus, expanding regulatory involvement. The Staff is proposing alternative methods of asserting control over the county's conditional use--EIR process. The Warren-Alquist Act simpl… more

Critical heat flux experimentation in an annular test section. [PWR]

Description: Steady-state critical heat flux experiments have been performed in the Forced Convection Test Facility (FCTF), an annular test section containing a single electrically heated rod, for the purpose of testing the applicability of existing critical heat flux correlations. Good accuracy has been obtained using the MacBeth-Barnett critical heat flux correlation for annuli, corrected for the ''stepped cosine'' power profile of the heater. The equivalent diameter of the test section, based on the wett… more

Heat exchanger method, ingot casting; fixed abrasive method, multi-wire slicing: Phase II. Silicon sheet growth development for the Large-Area Silicon Sheet Task of the Low-Cost Silicon Solar Array Project. Quarterly progress report No. 2, January 1, 1978--March 31, 1978

Description: A crack-free silicon ingot has been cast in a graded, semiconductor purity silica crucible. More than 90% single crystallinity has been achieved in 2.5 kg cast ingots. The impurities on the surface of the melt have been reduced with the use of a rapid heat-up cycle and absence of graphite retainers. Solar cells fabricated out of HEM cast material have shown conversion efficiency up to 14% under AM1 Xenon source illumination. Considerable progress has been achieved in casting square cross-sectio… more

Comparison of geothermal energy with coal, oil, and natural gas for selected uses

Description: Environmental effects and energy efficiencies for geothermal energy, western strip-mined coal, and eastern underground mined coal applied to space heating, process heat, and electric drive were compared. The measure of an environmental effect is the amount of residual material released to the environment, and the measure of energy efficiency is the second law efficiency of the process involved. The results indicate that geothermal energy efficiencies (second law) are higher than those for coal … more

Faulted stress analysis of the LOFT Lower Core Support Plate

Description: The LOFT Reactor Lower Core Support Plate has been analyzed using LOCA plus SSE loading. The LOCA loading was obtained from LTR 1115-39, Ref. 1, which used LOCA pressures from Ref. 5. SSE loading on the Lower Core Support Plate was obtained from LTR 1115-31, Ref. 2. The combination of LOCA plus SSE is considered a faulted loading condition. The analysis showed the lower Core Support Plate to be structurally adequate and that it meets all of the ASME Section III requirements for faulted conditio… more

Evaluation of the feasibility of joining titanium alloy to heavymet tungsten alloy

Description: Information is presented on a program to select and evaluate methods of brazing and/or explosively welding Ti-6Al-4V titanium alloy to Heavymet, a tungsten-base metal containing up to about 20% alloying elements (nickel, copper, etc.) to improve its ductility and other mechanical properties. Designs permitting the reliable production of joints between these base metals were of interest too. While this investigation was primarily concerned with an engineering study of the problems associated wit… more
