From abstract: This report describes a conceptual design for an Advanced Engineering Test Reactor. The reactor is a large graphite assembly penetrated by parallel Zircaloy tubes through which flow as heavy water solution of uranyl sulfate. Reactor power is 220 megawatts

The influence of hydrophobic solvation on the alkaline hydrolysis of ethyl esters of polar substituted 2-methylpropionic acids in water

The rate constants of the alkaline hydrolysis of 2-methylpropionic acid ethyl ester, alpha-hydroxy, alpha-bromo, alpha-cyano, and alpha-nitro-2-methylpropionic acid ethyl ester have been measured in water between 5-degrees-C and 45-degrees-C with the help of an appropriate conductance bridge developed in our laboratory. The influence of the polar substituents on the rate constant, a powerful probe for discussing two-particle interactions in solutions, is characterized by an intramolecular structure parameter of the activated complex and a dielectric parameter of its surroundings. The dependence of the reaction rate of the structure parameter is compared to that of substituted acetic acid derivatives. The smaller dielectric parameter of 2-methylpropionic acid esters reveals the increasing hydrophobic solvation in comparison to acetic acid derivates
