Design considerations for a fiber optic communications network for power systems

Description: The design of a fiber optic communication network for monitoring and control in power systems is discussed. It is shown that by appropriate choice of protocols, a fault-tolerant system can be built that operates in any arbitrary configuration. Since the network is based on fiber optics, it can be made fast enough for substation monitoring and control. In this application, a relatively small number of cables is required to implement a high reliability system. The network can also be used for dis… more

Nuclear electric propulsion for future NASA space science missions

Description: This study has been made to assess the needs, potential benefits and the applicability of early (circa year 2000) Nuclear Electric Propulsion (NEP) technology in conducting NASA science missions. The study goals are: to obtain the performance characteristics of near term NEP technologies; to measure the performance potential of NEP for important OSSA missions; to compare NEP performance with that of conventional chemical propulsion; to identify key NEP system requirements; to clarify and depict… more

Surfactant studies for bench-scale operation

Description: A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the second quarter of work. The major accomplishments were (1) completion of coal liquefaction autoclave reactor runs with Illinois No. 6 coal at processing temperatures of 300, 325, and 350[degrees]C, and pressures of 1800 psig, (2) analysis of the filter cake and the filtrate obtained from the treat… more
