Removal of H/sub 2/S from geothermal steam. Semi-annual report, April 1-October 31, 1975

Description: The program objective is to identify and evaluate a technique to remove hydrogen sulfide from geothermal steam before it is used for power generation. The last six months were spent in the literature search, sorbent preparation and evaluation, and construction of an experimental apparatus. Zn0, mentioned in the original proposal as a good candidate for H/sub 2/S adsorption, was verified as such by the literature search and laboratory experiments. However, regeneration of sulfided sorbent proved… more

Thermal hydraulic evaluation of advanced wire-wrapped assemblies

Description: The thermal-hydraulic analyses presented in this report are based on application of the subchannel concept in association with the use of bulk parameters for coolant velocity and coolant temperature within a subchannel. The interactions between subchannels are due to turbulent interchange, pressure-induced diversion crossflow, directed sweeping crossflow induced by the helical wire wrap, and transverse thermal conduction. The FULMIX-II computer program was successfully developed to perform the … more

GTF test program

Description: The goal of the GTF (Geothermal Test Facility) Test Program is to evaluate the geothermal resources in the Niland area and determine if they can be effectively converted into electric power. This program will examine the four critical areas of geothermal power development: (I) reservoir analysis, (II) energy extraction and conversion, (III) environmental effects, and (IV) operation and maintenance. These areas are discussed and a detailed test program is presented.

Nuclear fusion systems analysis research. FY 1975 annual report, 1 July 1974--30 June 1975

Description: This report summarizes research conducted during FY 1975 on the parametric systems analysis of fusion central power stations. As described in the report the methodology being pursued provides for a phased analysis starting with simple ''nominal'' parameters and associated computer codes and progressing to more complex functional models and then to physically based mathematical models for the systems of major significance in future power station viability. The nominal parameter analysis for prel… more

Baseline Gas Turbine Development Program. Eleventh Quarterly Progress Report

Description: Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1978 Federal Emissions Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard size American automobile. NASA completed initial heat balance testing of a baseline engine. An additional 450 hours were run on ceramic regenerators and seals. Seal wea… more

Modeling of solar heating and air conditioning. Progress report, October 31, 1974--December 31, 1975

Description: The principal objective of the research is to develop the means to identify and optimize practical systems for heating and cooling of buildings with solar energy in the United States. This will be done through simulation methods. Secondary objectives are to: extend and refine TRNSYS (a modular solar energy system simulation program); develop the means of supporting TRNSYS users in other laboratories; use TRNSYS (and other simulation programs) to develop design procedures for solar heating and c… more

Thorium utilization program. Quarterly progress report for the period ending November 30, 1975. [Fuel element crushing, solids handling, fluidized bed combustion, aqueous separations, solvent extraction, systems design and drafting, alternative head-end reprocessing, and fuel recycle systems analysis]

Description: The development program for HTGR fuel reprocessing continues to emphasize the design and construction of a prototype head-end line. Design work on the multistage crushing system, the primary and secondary fluidized bed burners, the pneumatic transfer systems, and the ancillary fixtures for semiremote assembly and disassembly is essentially complete. Fabrication and receipt of all major components is under way, and auxiliary instrumentation and support systems are being installed. Studies of flo… more

Nuclear Chemistry Research. Progress Report, November 1, 1974--October 31, 1975

Description: The major effort in the high-energy nuclear chemistry program was the study of cross sections and kinematic properties of products formed from the interaction of 1- to 300-GeV protons with heavy- (Bi and U) and medium-mass (Cu, Ag) nuclei. The products studied ranged in mass from approximately 20 to that of the target nucleus. Except in the case of near-target product nuclei ($delta$A approximately 10 to 20), no substantial change in cross section or recoil properties was observed at 300 GeV fr… more
