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 current widespread procedure relies on the use of a reactivity meter for differential control rod measurements in nuclear reactors. From an observational point of view, the reactivity meter will measure the correct core reactivity if the input to the meter is proportional to the neutron amplitude function. A single detector reading is generally proportional to the amplitude function only if the point kinetics approximation is valid, that is, if the spatial flux distribution is invariant in time.
