Hanford Engineer Works technical manual

Description: The uranium metal, as discharged from the piles in the 100 Areas, contains the alpha emitting product, plutonium, in concentration in the neighborhood of 150--250 grams per metric ton, along with similar amounts of beta and gamma fission elements. It is the purpose of the Separations Plant to effect the separation of this product from the uranium metal and fission elements, and to prepare a concentrated, relatively pure solution of plutonium nitrate as the final product of the Hanford Plant.

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

The trend of contamination in the air, the Columbia River, rain, sanitary water, vegetation, and wastes, at the Hanford Works for the period July, August, September 1947

Description: This report summarizes the contamination observed at the Hanford Works and vicinity for the period July, August, and September, 1947. Daily or weekly trends for all sampling locations as included in previous reports are omitted except in those cases where a true trend can be established. Statistical analysis to determine significant values and differences is used whenever possible. The report is divided into the following topic sections: meteorological -- wind conditions; extent of beta contami… more

Review of the stack discharge active particle contamination problem

Description: Quantities of the order of ten million to 100 million radioactive particles per month were emitted from the stacks over a period of several months. High activity in the range 0.1 to 3..mu..c was probably confined to large carrier particles of corrosion debris from iron ductwork in the separations plant ventilation air system. This report discusses chemical, physical and radiochemical properties of the particles, and possible biological and health effects of exposure to them. (ACR)

Radioactive contamination in the environs of the Hanford Works for the period October, November, December 1949

Description: This report summarizes the measurements made for radioactive contamination in the environs of the Hanford Works. The principal sources of the radioactivity originating as a result of operations at Hanford which affect the environment in this area are the two waste stacks in the separations area and the cooling water from the four pile areas. Measurements are also made on samples taken from the Hanford waste systems which are primarily confined within the project proper. Although monthly summari… more

Precipitation of plutonium(IV) oxalate in Task I

Description: Laboratory experience on the precipitation of Pu(IV) oxalate is summarized. Filterable Pu(IV) oxalate with a cake density of 0.6 to 0.7 g Pu/cm/sup 3/ cake was precipitated from Redox PR solutions containing 10 to 200 g/l Pu and 2 to 6 M HNO/sub 3/. Filtration ease increased with strike temperature from 35 to 60/sup 0/C. Optimum conditions for pre-reduction of Pu(VI) to (IV), precipitation, digestion, filtration and washing were determined for 60 g/l Pu. Separation factors of 80, 40, 20, and 12… more

Nitric acid recovery and ammonia removal: Modifications to the Redox dissolver off-gas systems

Description: Project CG-588 authorized the design and construction of dissolver and waste neutralizer off-gas scrubbers to remove the ammonia given off during coating removal and waste neutralization steps of the Redox operation. It has always been recognized that the nitrogen oxides in the dissolver off-gases, resulting from the dissolution of bare uranium slugs, could also be absorbed in water under proper conditions to give re-useable nitric acid. Consequently it appeared feasible to provide facilities w… more
