Detection and Identification of a Ruptured Fuel Element at the SM-1 (APR-1) Nuclear Power Plant

Description: Summary. In October 1960, increases in the fission product activity of the primary coolant of the SM-1 power plant indicated that a fuel element failure had occurred. Low power tests were run first to determine the nature and magnitude of the defect. Flux tilting experiments were then performed to determine the general location of the failed element. Finally, the primary coolant flowing through each of the fuel elements was sampled at low reactor power for relative iodine activity to determine the exact location of the defective element.. The element was found and replaced. Upon return to power, the fission product activity dropped back to its normal full power value.

Experiments and Analysis for SM-1 Core II With Special Components

Description: Abstract: This technical report contains a summary of analytical and experimental work performed on SM-1 Core II, with special components is presented. The effects of these special assemblies upon power distribution and core reactivity were calculated and compared to experimental measurements. A thermal analysis was conducted to determine steady state and transient performance of the special test components of the core as well as some of the hotter standard Core II components. Experimental work discussed includes individual reactivity effects of all the special elements and the total effect of all of the elements. Power mappings were also made and are reported.

Point Imperfections in Metals: Existance and Detection

Description: From introductory paragraph: "The factors which control the properties, and hence the utility, of an alloy are microscopic in nature. These factors are controlled by controlling the composition and past history of the material. control of the composition of the alloy determines for the most part the number and types of phases which will be present, while control of the past history of the alloy determines the grain size and degree of crystalline perfection within the grains. Since the electrical, mechanical, and many of the physical properties of a metal are highly sensitive to the degree of crystalline perfection, it is worthwhile to explore the nature and role of crystalline imperfections."

Pyrometallurgical Reprocessing of Thorium-Uranium Fuel

Description: From summary: "A proposed metallurgical procedure for reporocessing Th-U233 fuel has been outlined. Some basic experimental data pertinent to the proposed process which has been published elsewhere has been reviewed and some new data presented. In the dissolution of thorium-uranium alloy in magnesium the data show that protactinium precipitates with the uranium and cerium remains in the magnesium-rich solution. It is expected that yttrium, other light rare earth elements, the alkali and alkaline earth metals will also concentrate in the magnesium-rich solution while iron, chromium, zirconium, molybdenum, niobium and the more noble metals will concentrate in the uranium-rich phase."

Small Order Shape Factor in Na22

Description: From abstract: "The beta spectrum of Na22 has been examined using an intermediate-image beta-ray spectrometer operating at 2 1/2% transmission and 2.4% resolution. Five separate determinations of the maximum energy and of the slope of the form-factor plot were made. One determination was made using a charge-discriminating baffle inserted in the spectrometer. The unweighted mean of the five values for the maximum energy is 547.4 ± 1.0 kev. The unweighted mean of the five values for the form-factor slope is 0.023 ± 0.006 1/mc2."

Ternary Compounds Between Thorium Monocarbide and Thorium Dihydride

Description: From abstract: "The thorium-hydrogen-carbon system was studied by measuring hydrogen equilibrium pressures at various compositions and temperatures. Two compounds, ThC·ThH2 and ThC·2ThH2, were found and characterized. ThC·ThH2 has a hexagonal closest-packed lattice with ao=3.816Å and co=6.302Å. ThC·2ThH2 has a monoclinic lattice with ao=6.50Å, bo=3.80Å, co=10.91Å and β = 119°. The enthalpies of formation for each compound were determined."

Transport Reactions of Vanadium(III) Halides and Bromine

Description: From introduction: "...This investigation was originated to explore the possibility of vapor transport of VCl3 by chemical reaction. The reaction first considered was that of VCl3 and bromine which gave a rapid vapor transport of VCl3. Other work on solid solution formation in the system VCl3-VBr3 and transport of VBr3 in bromine developed thereafter."
