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. Th… more

Hanford Engineer Works monthly report, July 1944

Description: This progress report discusses activities at Hanford Engineer Works for the month of July, 1944. The organization size increased rapidly in July, jumping from 1384 to 1886, an increase of 502 employees. Shortages existed on special lines such as electricians, instrument mechanics, and power operators. The opportunities to interview and employ Construction personnel improved as the Construction, organization moved past its peak employment figure. 269 houses were completed in Richland and 370 occ… more

Wind dilution required to reduce to tolerance levels the activity due to xenon and iodine in HEW dissolver off-gases

Description: The radio-active xenon and iodine evolved during the dissolution of the uranium may present a health hazard within certain areas around the base of the stack through which the dissolver off-gases are discharged. Since the concentration of these elements in the uranium metal is directly proportional to the power of the pile* and is related to decay period of the metal in accordance with their half-lifes, the maximum rate of discharge of these elements from the stack at H.E.W. can be estimated fo… more

Characteristics of a standard tube

Description: Transmitted herewith are three charts showing the temperatures attained at various points of the slugs in a typical tube of a flat ended pile. These charts are based on the latest information available to us on September 15, 1944. They are valid for any power load when the water rate is 21.0 gpm, whatever may be the inlet temperature of the cooling water. A simple method is provided for correcting the curves for deviations in water rate from 21 gpm. There is appended a detailed explanation of t… more

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 evolution of iodine during metal dissolution

Description: During the dissolution in nitric acid of uranium metal which has been irradiated in a pile, radio-iodine (8.0 day) and radio-xenon (5.3 day) are liberated along with the oxides of nitrogen. Since in the plant these gases are discharged into the atmosphere, the presence of the activities (particularly radio-iodine because of its greater chemical reactivity) presents a physiological hazard. As a consequence, the cooling period (that is, the time between the discharge of the metal from the pile an… more

Production of I sup 131

Description: We have reviewed the problem of recovering I{sup 131} from the Separations Process and conclude that recovery is entirely feasible. This report contains recommendations for I{sup 131} recovery offered for consideration and are based on a technical study.

Production test 105-2-P (Supplement A) - Activity of pile discharge water (Activation of manganese and iron)

Description: This report discusses the Production Test 105-2-P (Supplement A) -- Activity of Pile Discharge Water. Previous studies of pile discharge water have shown that one of two processes is responsible for the large but variable amount of Mn{sup 56} activity present in the water. One process is the production of Mn{sup 56} by the reaction Mn{sup 55} on manganese impurity in the water. The amount of such impurity has been shown to be too small to produce the observed amount of Mn{sup 56} unless the mea… 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

The trend of contamination in the air, Columbia River, rain, sanitary water, vegetation, and wastes, at the Hanford Works and vicinity for the period October, November, December 1947

Description: This report summarizes the contamination observed at the Hanford Works and vicinity for the period October, November, and December, 1947. Trend charts showing trend of contamination for the various sampling locations are only included where a true trend can be established for the three month period; a thorough analysis of all trends will be considered in detail in the annual report from this section. The report is divided into the following topic sections: Meteorological -- dissolving data; bet… 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)

P Division Monthly Report, April 1948

Description: This progress report discusses activities of the P Division for the month of April, 1948. The D and F Piles operated at 275 megawatts throughout April except for scheduled outages. Each operating area had an extended outage to remove a portion of the brick from the wall which runs across the rear edge of the top of the unit and to replace the vertical neoprene seal between the front face and the experimental side shields. This program described in detail under Mechanical Experience. The B-Pile … more
