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).”

A simple model is proposed to investigate the relations between breeding, inventory, and doubling time in the blanket of a fusion reactor using the T(D,n)He4 reaction. It is assumed that the amount of tritium removed per unit time is proportional to the amount present and the effects of radioactive decay are included. A series of numerical calculations was made using pa rameters appropriate for a 5000-MW(th) reactor. From these calculations it appears that to keep the blanket inventory and the initial inventory for startup to reason able values, the tritium removal system must be de signed to provide a mean tritium residence time in the blanket less than ∼1 day, preferably with the mean residence time approaching 0.1 day. Breeding ratios in the range of 1.02 to 1.1 give acceptable doubling times and, in general, higher breeding ratios are not desirable, especially when considered from a hazards viewpoint.
