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 (open access)

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

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 contamination in air and radiation level in air; extent of contamination in the Columbia River; extent of beta contamination in rain; extent of alpha and beta contamination in sanitary water; extent of beta contamination on vegetation; and the extent of contamination in Hanford Wastes. An appraisal and review of all the results is considered in detail for each section.

Effect of Temperature and Reactivity Changes in Operation of the Los Alamos Plutonium Reactor (open access)

Effect of Temperature and Reactivity Changes in Operation of the Los Alamos Plutonium Reactor

The operation of the Fast Reactor is considered in terms of normal equilibrium conditions and normal shut-down. The proposed loading, control rod adjustment and subsequent "floating" operation are discussed. Safety devices and interlocks are described. Temperature and reactivity changes are examined with respect to various system failures, phase changes, and "flashing" of the reactor. Slow changes due to faulty slug cooling are also considered. The calculations were initially based upon 10 kw operation. Performance tests of the mercury system now indicate that 20-kw operation may be feasible. (D.E.B.)

P Division Monthly Report, April 1948 (open access)

P Division Monthly Report, April 1948

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 was maintained in standby condition with a water flow of 10,150 gallons/minute. The 100 Area discharge rate continued at 60 tons per month. The exclusive use of lead dipped 4 inch slugs fabricated from alpha rolled or alpha extruded metal was started effective April 1. Work was stated April 12 in the 300 Area on a program of decanning 160 tons of 8 inch gamma extruded triple-dip canned pieces which were not considered good risks for pile operation. The slug recovery operation was placed on a 2 shift per day schedule on April 19 to expedite this work so that the metal can be recast and rolled at the earliest moment. The 300 Area canning …

Isolation and Propterties of Curium (open access)

Isolation and Propterties of Curium

The isolation of curium, element number 96, in relatively pure form has been accomplished. A method, involving a solvent extraction process, is given for the purification of americium from lanthanum and other ions. The discovery of a higher oxidation state of americium led to a method of separating americium from curium. Separation of the two elements was also accomplished by use of ion exchange resins. The details of the isolation of curium are given; the results of the spectrographic analysis, specific activity measurement, and calorimetric determination of half life showed the curium to be relatively pure. The absorption of light of various wave-lengths by an aqueous solution of Cm(III) is described, and some physical effects of the radiation from the curium are noted.

Analytical Services - Pile Area Laboratories

This is a report on Analytical Services of the Pile Area Laboratories at Hanford. Pertinent facts are listed regarding the analytical services currently provided by the Analytical Section in the pile areas. The work of the Analytical Section in the pile areas may be classified into five categories as follows: Analysis of pile process water, analysis of power plant (boiler) waters, analysis of drinking water, analysis of columbia (non-process) and Yakima River water, and preparation of reagents and standard solutions.
