Source of high activity levels recently observed from shipping containers and transfer cans

Description: Shipping cans containing product from plant runs completed in the latter half of April and in May showed, in general, definitely higher levels of radiation than had been observed previously. Likewise, containers for the transfer of the F-10-P solution from the 224 Bldg. to 231 Bldg. (during May) exhibited higher radiation levels than could be attributed to higher power levels and increased batch sizes. These higher radiation levels were indicative that some radioactive element (or elements) was… 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.

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.

The metal fabrication program for the Clinton Engineer Works and the Hanford Engineer Works. Including the Dummy Slug Program and the Unbonded Slug Program -- Project 1553

Description: The uranium slugs were used as the charge into the pile for the manufacture of minute quantities of plutonium. So little was known of uranium`s commercially adaptable physical properties that it was relegated almost to the category of a laboratory curiosity. A series of experimental and developmental programs were inaugurated to determine not only the extrudability, machinability and other physical properties, but also the influence on these of microscopic quantities of impurities present in th… more

Technical Department report on Production Test No. 313-58-M: Recovery of lead dipped slugs

Description: A number of slugs have been dipped in lead, then Al-Si and canned. Laboratory experiments showed that the can and outer bonding layers could be removed by the standard caustic-nitrate treatment. The alloy layer was removed from several slugs by hot nitric acid without use of hydrofluoric acid. It was desired to extend the method to the plant process and to clean accumulated lead dipped pieces. Lead dipped slugs may be cleaned by the regular recovery process with a weight loss of about 0.03 lbs.… more

Report on production test No. 313-69-M: Effect of straightening rods before outgassing upon warped slugs

Description: Strains are introduced into bars by cold working in the straightening operation. If no treatment is applied to relieve the strains after the straightening operation, it is conceivable that they may be relieved in the canning process and cause warped slugs. The purpose of this test was to see if fewer non-seats would occur among slugs machined from bars that were outgassed after straightening. Seven hundred and thirty-five slugs from bars that were straightened before outgassing were caned by th… more

Report on Production Test No. 313-68-M: Recanning of warped slugs segregated after the centrifuge by technical warp gauge

Description: It has been found that warped slugs which produce ``non-seats`` segregated after the centrifuging operation by use of a suitable gauge. The slugs which do not pass the gauge are quenched in water and set aside for later recovery. The purpose of this test was to determine if the rejected slugs could be straightened, degreased and recanned by dipping them directly in the bronze and then through the subsequent steps. One hundred and twenty-nine slugs rejected by the warp gauge were straightened, d… more

Minutes of meeting on Columbia River studies

Description: This document contains minutes of a meeting on Columbia River studies that took place on July, 13, 1945. Topics discussed include: dispersal of thermal effluent, viability of current sampling techniques, survey records of chemical and bacteriological analysis, the results of the fish study, analytical procedures to determine the addition of small amounts of addition agents, radioactivity studies, and determination of new sampling points.

History of operations, 1 January 1944--20 March 1945

Description: The objectives of Hanford operations are the production of sufficient quantities of plutonium and secondary products in time to meet adequately military requirements at the lowest cost of manpower, money, and materials commensurate with the maximum degree of certainty in attaining the objectives. The facilities operations at Hanford are described.

Turbidity coagulant for Columbia River water

Description: In this document, information about the need for a better compound to for filtering process water from the production reactors. It was found that the natural turbidity in the Columbia River was high enough to necessitate the use of a coagulant to minimize the passage of iron through filters. Tests indicated that Ferrisul was the better of the two compounds tested.
