Loss of Radioactivity from Barium Carbonate Samples

Description: The exchange loss of radioactivity from solid samplos of barium carbonate through the agency of carbonic acid and its ions has been investigated under a variety of conditions. It is concluded that the losses observed are greatly dependent upon the method of sample preparation, in particular the nature or any heat treatment which the sample materials undergo.

DT-IP-434-D: Irradiation effect on ceramic materials

Description: The purpose of the test described in this report was to determine the effect of production reactor flux on ceramic materials being considered for lining the vertical safety rod channels at the production reactors. This document is being written to describe the test, the results to date, and the work which remains to be done. The materials being evaluated in the test are: Aluminum silicate (Maryland Lava Co.); silicon nitride bonded silicon carbide (Norton Co. ``crystalon``); and aluminum oxide … more

Tail stock study. Quarterly report, April--June, 1970

Description: This project is to investigate and determine minimum, safe, and reproducible tail stock forces appropriate for use in the fabrication of creep and tensile specimens for HE. The survey conducted revealed that tensile specimens were machined with a tail stock force of approximately 60 psi. The tail stock force was reduced to 6 psi by incorporating center holes in the machining operation. Comparison tests between tensile specimens fabricated with a tail stock for ce of 10 psi and 50 psi clearly in… more

Plutonium chemistry of the ocean

Description: Plutonium is a man-made element whose behavior in the marine environment is inadequately known at present. It has been studied intensively in connection with production of weapons and power sources and has been characterized as an extremely toxic substance. Nevertheless, only a few dozen measurements have been made of concentrations in seawater and in the associated organisms and sediments. The first of these were as recent as 1964. There are reasons to believe its chemical behavior in the ocea… more

Specimen mounting methods for metallography

Description: >The development of metallographic mounting methods is reviewed and several of the more common methods being used are discussed. Characteristic advantages and disadvantages are pointed out. Retention of sample edges for examination is essential in many investigations, and a separate section is devoted to the many techniques devised to achieve this goal. It is noted that there is a mounting technique available for virtually any type of specimen. (14 figures, 6 tables, 57 references) (JRD)

Thermal conductivity of oriented fibrous carbon insulation from 300 to 1300 K in nitrogen and argon at one atmosphere

Description: From joint meeting of the American Nuclear Society and the Atomic Industrial Forum and Nuclear Energy Exhibition; San Francisco, California, USA (11 Nov 1973). The thermal conductivity, lambda , of three samples of oriented fibrous carbon insulation was measured from 300 to 1300 deg K in a radial heat- flow apparatus. Preparation of the 0.18 g/cm/sup 3/-density samples by a vacuum filtration process from carbon fibers and powdered phenolic resin, characterization of the material after carboniza… more

Plutonium and environmental metals in man. Interlaboratory meeting, May 9, 1973

Description: From plutonium and environmental metals in man conference; Albuquerque, New Mexico, USA (9 May 1973). The various aspects of handling human autopsy tissues and methods used for the determination of Pu in tissues are discussed. Types of cases are classified as: the general population, with no known exposure to actinide elements; former AEC personnel which had an exposure potential; and Transuranium Registry cases representing known exposures to Pu and other actinides. It is pointed out that 5 mi… more
