ANS joins others in seeking to discuss SNF/HLW impasse
The American Nuclear Society joined seven other organizations to send a letter to Energy Secretary Christopher Wright on July 8, asking to meet with him to discuss “the restoration of a highly functioning program to meet DOE’s legal responsibility to manage and dispose of the nation’s commercial and legacy defense spent nuclear fuel (SNF) and high-level radioactive waste (HLW).”

The time-dependent and steady-state solutions for the transmission of a gaseous radioactive isotope through an adsorber bed are derived. The transmission, defined as the ratio of the outlet concentration to the inlet concentration, depends on three dimensionless quantities, namely, the dispersion number Δ, the product of the radioactive decay constant and the propagation time λtp, and the dimensionless time t/tp. Based on the mathematical results, criteria are given for the design of adsorber beds for decreasing the concentration of a radioactive contaminant. An example illustrates the possibility of reducing the radioactivity of short-lived xenon isotopes in a carrier gas flowing through adsorber beds; however, consideration must be given to the low efficiency of the adsorber bed resulting from dispersion effects.
