Laboratory Studies of Al-Ni-U Bonding: Interim Report

Description: The purpose of this report is to summarize laboratory work concerning Al-Ni-U bonding. It was initiated by an analysis of the literature and hot die size bonding in particular. A hot die size bond has three major deficiencies. It is possible that one or more of the deficiencies could be alleviated by adjusting the hot die size bonding conditions, but most likely at the expense of aggravating the other deficiencies. To date the HDSB process has been superbly engineered to yield a high quality bo… more

A method to simulate interchannel flow through fuel element junctions during laboratory tests on a C-Reactor fuel model

Description: Interchannel flow through fuel element junctions can occur in production reactor fuel columns as a result of different pressure loss patterns in the two coolant subchannels. This interchannel flow is most significant during boiling conditions because, generally, the boiling length in each subchannel is different. These different boiling lengths result in divergent pressure loss characteristics in the subchannels and cause differential pressures to exist across the fuel element junctions. These … more

MFC study - krypton and xenon recovery

Description: As commercial fuels reprocessing develops, large quantities of radioactive and stable fission rare gases will become available. These gases pose both a problem and an opportunity. When efficient methods of control and recovery are developed, the cost of these materials will be greatly reduced. With increased availability and reduced costs, commercial and government applications would be accelerated. Thus the fission gases which present potential environmental problems, would become useful by-pr… more

A preliminary evaluation of the thermal effects of the Ben Franklin Dam project on Columbia River temperatures below the Hanford Plant

Description: The planned construction of the Ben Franklin project below the Hanford production reactors poses the question of determining to what extent this project will affect the Columbia River temperatures. Using the plant operations record for the year 1966, and the weather record for the same period, a series of simulation runs was made to determine the effects of the clam on the temperature regime, and the extent to which density currents could be expected to develop. This information is to be used a… more

Thermal mapping of the Columbia River at Hanford using an infrared imaging system

Description: The infrared imagery data was collected September 13, 1966 from 1010--1013 o`clock, using a mercury-doped germanium detector which was filtered to respond to wave lengths of infrared radiation. The magnetic-tape recorded information was processed with a computer program to obtain quantitative evaluations of river temperature variations and to accurately define surface temperature patterns resulting from the discharge of reactor effluents into the river. The river surface-temperature information… more

K-Reactor: Loss of coolant temperature study of the biological skin

Description: It is of interest to investigate the time following a complete loss of coolant incident when the pile would be exposed to the ambient air. This is of concern due to the fast propagation of graphite burn-up when brought in contact with air at or above the operating temperature of the graphite (1292{degree}F). One possible way conjectured in which the pile can be exposed to the surrounding environment is for the centering flange gasket (neoprene) or the bellows gas seal (silicone) to fail. This p… more

Lithium-aluminum separations request

Description: A test irradiation of lithium was recently completed in one of the Hanford K Reactors. It is requested that these lithium-aluminum alloy targets be separated and analyzed for tritium content. This request is for the analysis to be performed on two groups or batches of samples. The first group would be 38 elements with a total gas content estimated to be approximately 97 liters. The second batch would consist of 76 elements with a total gas content estimated to be approximately 193 liters. This … more

Zirconium hydride formation in Hanford production reactor process tubes

Description: Examination of Zircaloy-2 process tubes from Hanford Production Reactors has revealed extensive zirconium hydride formation. In general, attack is limited to the downstream portions of tubes where aluminum spacers are located. Most of the hydride platelets are contained in a case or layer on the inner surface of the tube. It is not unusual to find cases 0.004 to 0.005 in. thick. Analyses of the 0.037 in. wall tubes with such cases intact often reveal hydrogen concentrations greater than 1000 pp… more
