Hanford Engineer Works technical progress letter No. 146, April 13--19

Description: Further data on the changes in length and weight of expanded graphite samples which were exposed in the pile in atmospheres of oxygen, carbon dioxide, and helium show that all three gases produce roughly the same shrinkage and weigh loss. This result is unexpected in that there is no precedent for such behavior in a helium atmosphere; however, it was found that water vapor had entered the helium stream by some unknown means and had condensed on the plugs at the inlet end of the tube. This opens… more

Water leak, 100-F Area

Description: This document serves to record pertinent information regarding detection and repair of a water leak in Process Tube No. 3169-F in the F File and subsequent steps necessary to remove the water from the pile in order to return to normal level.

Trip report: Argonne National Lab., Naval Reactor Division, December 12--13, 1949

Description: This trip was spent in conferences with H. Etherington, A. Amroni, Geo. Anderson, and L.W. Fromm; and in inspection of components now being built for the Navy Test Rig which is to be installed at H Pile. Mr. Anderson believes that the entire assembly will arrive at Hanford between January 16 and 23, 1950. Much has yet to be designed and built, however. Also, certain incompatibilities with the H Pile were pointed out, and will be altered.

Redox Committee: Conference notes and recommendations, meeting of April 11, 1949

Description: This report discusses recommendations for development work on the Redox Production Plant. It contains an outline for a relationship procedure between the architect engineer and General Electric Design Division; preparation of a material balance and process flow; the preparation of engineering flow diagrams, including lists of standard symbols for these diagrams; a material and equipment list; a project cost estimate; and Procedures covering institution and execution of work involving studies by… more

Columbia River temperature study at 100-F Area

Description: In August 1946 it was discovered that two effluent lines near the Columbia River at Hanford were damaged. The upstream effluent line has broken off 37 fact from the shoreline and the downstream effluent line had been bent and partly broken seventeen feet from shoreline and has swung downstream to a point about 50 feet from shorelines. This study was made to determine how fast and in what fashion the temperature of the effluent water is dissipated in the Columbia River under the present conditio… more

Monthly, 100 Area technical activities report, Physics, 10-25-45--May 1947

Description: Two events of broad significance occurred in the 100B Area during this report period. These are the discovery of pimpled slugs in high concentration tubes discharged on 10-30-45 and the discovery of leaking VSR thimbles on 11-15-45. Although more extensive reports of these occurrences will be made elsewhere, these events have aspects of significance to physics and basic data will be given in this report for record purposes.

Graphite expansion committee meeting of January 10, 1947

Description: The thirteenth meeting of the Graphite Expansion Committee was held on January 10, 1947. A summary of meeting topics follow. The horizontal bowing of Tube 4494-D in the top corner of the pile is considerably greater than the bowing which can be attributed to graphite expansion at this elevation in the pile, indicating that the top layers of graphite are being dragged outward by expansion of the underlying layers. Such a phenomenon could shear the vertical thimbles at a point just below the ther… more

A study of proposed semi-parallel and complete parallel operations of the Canyon and concentration Buildings, 200 Areas

Description: Due to a forecasted increase in pile area production as well as a possible decrease in batch size of the separations process, an increase in the capacities of the separations plants is indicated. It is the purpose of this report to review this relationship in the light of existing data and to determine how this additional capacity can best be attained through the use of either the proposed semiparallel or complete parallel methods of operation. Emphasis will necessarily be given to consideratio… more

Allowable temperature rise in tubes of the piles: Precautions against boiling

Description: In the design of the pile, it was considered advisable never to impose so great a heat load on any tube that the available header pressure would be insufficient to sweep the tube free of vapor if boiling should accidentally be initiated in the tube. Figures are given for the maximum temperature rises permissible, as function of header pressure and orifice diameter.

Graphite expansion committee meeting of January 7, 1947

Description: The fourteenth meeting of the Graphite Expansion Committee was held on February 7, 1947. Laboratory studies indicate that either the graphite thermocouples are reading low or that annealing effects at elevated temperatures within the pile are much greater than those encountered In the laboratory. Current difficulties with operation of some of the horizontal and vertical control rods seem to be attributable to graphite expansion, though no complete understanding of the phenomena has been obtaine… more
