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."

Report explaining some different categories of special refractory materials. These categories of materials and their properties are discussed as well as the specific materials that fall into these categories.

Report describing the results of corrosion tests on 68 types of materials. Generally, most materials were tested with an agitator and vapor and some were tested a 3rd way with alternate immersion.

"The experience at Oak Ridge National Laboratory in decontamination equipment and working areas from radioactivity has been summarized." The methods and reagents that were used for decontamination are discussed.

Abstract: Part I: A series of extraction experiments has been performed to determine the distribution coefficient of uranium(VI) between dilute perchloric acid and benzene solutions of TTA. The data are interpreted to show that the principal species in the acid phase is a doubly charged ion, UO2++. The discrepancies revealed in previous work(1) were not found. Part II: The spectrophotometric method of analysis developed for use in Part I has shown the existence of previously unreported species of uranium(VI) in the presence of TTA: UO2K2-HK in benzene, and UO2K+ in dilute acid. The absorption spectra of all the principal species are reported.

A quarterly report consisting of reports published on Transuranic Elements from the University of California Radiation Laboratory. Each report is a brief one to two page summaries of the article submitted for publication during the months of September-November, 1948.
