Molten-salt Reactor Chemistry
This document summarizes the large program of chemical research and development which led to selection of fuel and coolant compositions for the Molten-Salt Reactor Experiment (MSRE) and for subsequent reactors of this type. Chemical behavior of the LiF-BeFrZrFrUF4 fuel mixture and behavior of fission products during power operation of MSRE are presented. A discussion of the chemical reactions w...
متن کاملThe Molten Salt Reactor Adventure
A personal history of the development of molten-salt reactors in the United States is presented. The initial goal was an aircraft propulsion reactor, and a molten fluoride-fueled Aircraft Reactor Experiment was operated at Oak Ridge National Laboratory in 1954. In 1956, the objective shifted to civilian nuclear power, and reactor concepts were developed using a circulating UF4-ThF4 fuel, graphi...
متن کاملReactivity Oscillations in Molten Salt Reactors
The modification of the fuel composition in a molten salt reactor can cause the precipitation of fissile materials and thus the generation of fissile lumps moving within the system and introducing localized perturbations of multiplicativity. The problem of reactivity oscillations connected to this phenomenon in circulating fuel systems is addressed. The periodic behavior of such reactivity inse...
متن کاملInherent structure of a molten salt
We calculated the inherent structure of a model melt of zinc ~II! bromide over a wide range of densities. Stable, metastable, and unstable branches were obtained for the zero temperature pressure–volume isotherm of the inherent structure. The pressure–volume isotherm, the void distribution, and the structure factor were used to identify the spinodal, independent of any model equation of state. ...
متن کاملIonic liquid (molten salt) phase organometallic catalysis.
For economical and ecological reasons, synthetic chemists are confronted with the increasing obligation of optimizing their synthetic methods. Maximizing efficiency and minimizing costs in the production of molecules and macromolecules constitutes, therefore, one of the most exciting challenges of synthetic chemistry.1-3 The ideal synthesis should produce the desired product in 100% yield and s...
