SRE CONTROL ROD SHIELDING REQUIREMENTS

Description: Data taken on radiation traverse of the Mark 1 control rod were analyzed. Future radiation levels for all SRE control and safety rods were predicted from this. The shielding necessary to ship a complete rod and that necessary to protect a person doing maintenance work on these rods were calculated. The unshielded gamma dose rate 1 cm from the surface of the most highly activated portion of the control rod was calculated to be 5.0 x 10/sup 4/ r/hr 14 days after shutdown following an extended pow… more

RECONNAISSANCE FOR URANIUM IN THE CUZCO-AYAVIRI REGION, SOUTHERN PERU

Description: Geologic and radiometric investigations of the CuzcoAyaviri region in southern Peru were made in a search for geologic features or structures which might be favorable for the occurrence of uranium. Outcrops consist of Lower Paleozoic sedimentary and metamorphic rocks; Permian to Carboniferous volcanic flows, tuffs, breccia and agglomerate, together with sedimentary rocks; and Cretaceous and sedimentary rocks. Cretaceous to Tertiary igneous rocks are acidic intrusives and extrusive rhyolite, dac… more

RECONNAISSANCE FOR URANIUM IN THE PROVINCES OF AYABACA AND HUANCA-BAMBA, DEPARTMENT OF PIURA, PERU

Description: In 1957 a radiometric examination of rock outcrops in the Ayabaca and Huancabamba areas of northwestern Peru was made in conjunction with a geologic search for structures favorable for the occurrence of uranium minerals. No anomalous radioactivity was detected, and the geologic setting is believed to be generally unfavorable for uranium mineralization. (auth)

Chemical Effects of Nuclear Transformations and Their Use in Making Labeled Compounds

Description: The chemical effects of nuclear transformations can be utilized to introduce the radioactive atoms produced into chemical species useful for tracer studies. Gas chromatography offers a means of separating the tagged compounds with high specific activity. A chromatographic apparatus for separating and identifying labeled compounds is described. Comparisons are made of this with other labeling techniques. (auth)

Ultrasonics for Radioactive Decontamination

Description: Tests have been run to determine in a preliminary fashion whether ultrasonic vibration would be effective in removing mixed radioactive deposits from the inside surface of steel pipes in a heat exchanger. Different frequencies (20 KC/S, l000 KC/S) have been used at the maximum power levels conveniently attainable. Different liquids were compared for cleaning effectiveness, with and without ultrasonics. Mild stirring of water bath at room temperature produced virtually no cleaning effect on the … more

A SHIELDED METALLOGRAPH FOR REMOTE METALLOGRAPHY. Topical Report- Metallurgy Program 6.10.6

Description: A unique concept is featured in the adaptation of a Bausch and Lomb Research Metallograph for remote metallography at Argonne National Laboratory. The metallograph is placed outside and adjacent to the metallographic preparation hot cell, and only the microscope section is shielded. This arrangement results in the decisive advantages of simplified adaptation for remote operation, and unaltered optical system, and greatly reduced shielding bulk. A mechanical transfer system shuttles the irradiat… more

Uranium Series Disequilibrium in Radioactive Ores

Description: From introduction: The purposes of this paper are to tabulate and discuss the results of a number of complete disequilibrium analyses, to illustrate a proposed classification of disequilibrium patterns, to study these disequilibria as clues to the understanding of the geochemical history of the samples and of the deposits, and to point out some of the difficulties when simply comparing radioactivity and chemical uranium assays for interpreting equilibrium or disequilibrium in samples.

THE ECONOMICS AND HAZARD POTENTIAL OF WASTE DISPOSAL

Description: The two most important considerations in the disposal of radioactive wastes are safety and economy. All other steps in the waste disposal complex must be tuned to accomplish these two goals. In general, the hazardous waste in the nuclear power complex affect the cost of the nuclear power reactor fuel cycle, the general environment since disposal must exclude radioactivity from the environment for over 500 years, the costs and/or methods of waste treatment including fission product utilization, … more

A STUDY OF MECHANICAL-ELECTROLYTIC POLISHING ON URANIUM METALLOGRAPHIC SPECIMENS

Description: Proposed techniques for 'hot'' metallographic preparation are described. The following data from experiments on saw cutting, hand grinding, and electrolytic polishing have been obtained: radioactive contamination from saw cutting and grinding; depths of scratches and cold worked metal from saw cutting and grinding; metal removal rates for various grades of emery grinding papers; metal removal rates for electropolishing; optimum sequence for specimen grinding on emery papers; and time requiremen… more

Efficiency of Scavenging Devices in Determining Falloug. Progress Report No. 6 March 15 to July 31, 1957

Description: A fall-out sample collector was designed and tested for use in collecting samples at the soil surface. The sampler consists of artificial grass and a stainless steel pot. Results are included from preliminary studies on the scavenging properties of artificial grass. The effects of relative humidity, rain, and wind velocity on the efficiency of scavenging devices were investigated. A comparison was made of Sr/sup 90/ fall-out data from samples collected on gummed film and surface soil samples fr… more
