Spectrophotometry of Neptunium in Perchloric Acid Solutions

Description: Report discussing a study testing features of the absorption spectra of different oxidation states of neptunium and perchloric acid concentration's effects on the spectra. Data regarding a disproportionation reaction present in neptunium(V) solutions in concentrated acid is included.

Radiations of 6.7d U²³⁷

Description: Abstract: The radiations of U²³⁷ have been studied using a magnetic lens beta ray spectrometer and scintillation spectrometers for betas and gammas singly and in coincidence. A beta with an end point energy of 245 keV was found along with evidence for the existence of lower energy components. Gammas of energy 27, 42, 49, 59, 166, 208, 269, 354, 431, and 467 keV were found, and probably a gamma of 102 keV. The decay scheme constructed gives a total decay energy for this isotope of 512 keV.

Production of Xe¹³¹, Xe¹³⁵, Kr⁸⁵m and Kr⁸⁵ From Plated-Out U²³⁵ in the MTR Core

Description: This report discusses details of the release of Xe¹³¹, Xe¹³⁵, Kr⁸⁵m and Kr⁸⁵ into the process water system of the MTR along with the development of high process water radioactivity. It is suggested that this release followed the fissioning of U²³⁵. Equations that produce the rate of release of fission products is given and approximate rate of release is represented in a graph.

Measurements of an Iron and Borated Water Shield in the Lid Tank : Experiment 10

Description: The following report measures a shield mockup in three regions: the first made almost entire of iron; the second, transition, region is made of various thicknesses of B4C; and the third region was borated water. The iron samples used in the experiments were made in the form of rectangular plates and place in the lid tank; however, the plates were not completely flat and created a water gap that was measured in this report.

Note of the Function of the Aquadag in the Stellarator

Description: The following report introduces the aquadag, a part of the stellarator with the purposes to prevent the non-uniform accumulation of electrostatic charges on the walls of the stellerator and to free the electrons of the stellerator and provide accelerations, achieving a uniform field distribution.

Corrosion of Aluminum and Beryllium by MTR Canal Water

Description: Introduction: "In the early operation of the WTR severe canal corrosion of dummy fuel assemblies and a beryllium A-piece caused a great deal of concern as to the possible effects of long-time canal storage on such elements. A short-term experimental program was started to determine the causes of this corrosion and to correct them before any irradiated fuel elements had to be stored in the canal. The results of this program are presented here."

Dynamic Corrosion and Mass Transfer of Chrome Steel by Bismuth

Description: From introduction: "This report summarizes the experimental data obtained at the San Pablo Laboratory on the corrosion of 5% Cr - 0.5% Mo steel by bismuth under conditions that allow mass transfer to occur. The bismuth is circulated through a temperature gradient by means of a thermosiphon loop."

Thermal Conductivity of Uranium-Chromium and Uranium-Iron Eutectic Alloys

Description: Report discussing measurements of thermal conductivity and heat capacity for uranium-chromium and uranium-iron eutectic alloys at room temperature. The resulting values were intended for use in design calculations until more accurate data at other temperatures was obtained.
