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).”

It is conventional practice in the design of nuclear reactors to introduce hot channel factors to allow for spatial variations of power generation and flow distribution and for manufacturing tolerances. The factors are presently considered to be cumulative; the over-all hot channel factor at a point in the reactor is the product of all the factors applicable at the point. This paper demonstrates a more exact method of determining and interpreting the combined as well as individual hot channel factors through the use of statistical methods.
