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.

Growing the future nuclear energy workforce in the Volunteer State
The Volunteer State’s governor and representatives have made clear their intention to position Tennessee at the forefront of a nuclear energy growth surge over the next several years. They’re making the financial investment to back up this commitment, pledging $50 million to recruit the innovative and invest in the existing nuclear companies in the state.
In an interview with advocacy group Nuclear Matters, Gov. Bill Lee expressed his excitement and optimism for Tennessee’s nuclear future.
“Tennessee is one of the fastest growing states in the country,” he said. “Because of that, we have people and companies moving here and we need to have a dependable, reliable energy source.”

In modeling condensation from vapor-gas mixtures with the heat and mass transfer analogy, there are two parallel methods in the literature to account for variable property effects: (a) the property ratio scheme using an empirical factor as a multiplier for the mass flux and (b) the reference property scheme using reference properties to calculate the mass flux. The current work focuses on the reference property scheme and establishes its relation to the property ratio scheme. From condensation boundary layer analysis, the current work proposes a reference mixture composition and a reference mixture temperature, which can be used for calculation of a variety of reference thermodynamic and transport properties. It is demonstrated that the empirical factor in the property ratio scheme used widely in the literature can be obtained from the reference property scheme derived in the current work, and thus, the two parallel methods to account for variable property effects are equivalent. A common mistake in using the reference mixture composition is highlighted as part of this investigation. The reference property scheme presented herein has a theoretical basis and is more accurate over a wide range of conditions than the empirical property ratio scheme. Finally, the reference property scheme is extended to multicomponent gases.
