Hot Fuel Examination Facility named a Nuclear Historic Landmark
The American Nuclear Society recently announced the designation of three new nuclear historic landmarks: the Hot Fuel Examination Facility (HFEF), the Neely Nuclear Research Center, and the Oak Ridge Gaseous Diffusion Plant. Today’s article, the first in a three-part series, will focus on the historical significance of HFEF.

Analytical solutions to the unsteady diffusion equation in spherical geometry are presented for uniform and composite porous media. In this case, a Neumann (prescribed flux) boundary condition is assumed as opposed to a Dirichlet (prescribed concentration) boundary condition used in previously published derivations. For radionuclides that have very high solubility under a given set of geochemical conditions, such as 99Tc and 79Se under oxidizing conditions, a prescribed flux boundary condition is more appropriate.
