Boron stainless steel for drop rods (open access)

Boron stainless steel for drop rods

From introduction: "The present investigation of the properties of boron stainless steel is an outgrowth of a project started in 1947. The problem is to replace the present steel used for drop rods in the Hanford piles with a material much less subject to corrosive attack from the humid atmosphere existing at the location of the rods."

Methyl Methacrylate Casting Resin (open access)

Methyl Methacrylate Casting Resin

Abstract: "This report describes work done to improve the casting characteristics of methyl methacrylete resin under CMR-6-18 authorization. The experimental program was initiated with the objectives of decreasing casting time, bubble formation and shrinkage. It has been found that by use of a common solvent for monomer and polymer concentration in monomer can be attained greater than any previously reported in preparation of a methacrylate casting resign. Incorporation of this greater amount of polymer has produced the desired effects. A bibliography of relevant literature is included to which reference is made in the text."

Review of the stack discharge active particle contamination problem (open access)

Review of the stack discharge active particle contamination problem

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)

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.

Safety Tests on Hand Stacking of U-235 Cubes (open access)

Safety Tests on Hand Stacking of U-235 Cubes

From abstract: "Critical assembly tests have been made on the Pajarito Universal Machine to determine the safety limits of handstacking cubes of 95% U-235 in spherical geometries preparatory to making critical assemblies of U-235 in an "infinite" tuballoy tamper. The U-235 cubes were stacked as pseudospheres in a cavity at the top of a tuballoy block 12" high and 8" on a side, and the assembly tamped by locating it inside a doughnut shaped water tank whose tamping effect is equivalent to the tamping caused by personnel necessary for hand stacking."

Correlation of Chemical Analyses on Graphite Bars and Test Pile Results

From abstract: "The chemical analyses of graphite test bars obtained from National Carbon Company and the analyses performed by the Hanford Works Laboratories Division do not correlate significantly with the test pile results, nor do the chemical analyses obtained from National Carbon Company agree with those done in the Handford Works Laboratories. Chemical results obtained at Hanford on samples taken lengthwise from individual bars correlated significantly with the individual test pile results."

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

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; beta contamination in the air and the radiation levels in air; alpha and beta contamination in the Columbia River; beta contamination in the rain and snow; alpha and beta contamination in drinking water; beta contamination on vegetation; and alpha and beta contamination in Hanford Wastes. An appraisal and review of all the results is considered in detail for each section. Statistical analysis is used whenever possible to determine significant values and differences in levels of contamination measured.

Biology Seminar : methods of assaying for plutonium in biological materials (open access)

Biology Seminar : methods of assaying for plutonium in biological materials

From introduction: "Since plutonium is manufactured at the Hanford Works, a study of its effect on biological materials is important. To determine the amount of plutonium deposited in a biological sample, it is necessary to have an accurate method for extracting plutonium from these samples. Some of the different methods for plutonium assay are reviewed and given in this paper."
