ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.
Meeting Spotlight

A summary is presented of the available physical property data on 94 molten fluoride salt mixtures which have been evaluated for utilization as high temperature fluid fuels and reactor coolants. The specific physical properties which were either measured or calculated include density, heat capacity, heat of fusion, enthalpy, viscosity, thermal conductivity, and electrical conductivity. The experimental techniques and apparatus used in making the measurements are described, and the probable experimental errors are given. Some of the problems and potentialities of reactor systems using molten salt fuels and coolants are also briefly discussed.
