Economics and finance of Molten Salt Reactors

Molten-salt Reactors—history, Status, and Potential

Molten-salt breeder reactors (MSBR's) are being developed by the Oak Ridge National Laboratory for generating low-cost power while extending the nation's resources of fissionable fuel. The fluid fuel in these reactors, consisting of UF4 and ThF4 dissolved in fluorides of beryllium and lithium, is circulated through a reactor core moderated by graphite. Technology developments over the past 20 y...

Reactivity 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...

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...
