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).”

As for the modulation process of a traveling wave direct energy converter (TWDEC), which will be used in D-3He fusion power generation and has a principle of a reversal process of linear accelerator, numerical analysis of particle orbits has been performed. Space charge effect is taken into account to examine lower modulation effect found in simulation experiments. In the high incident particle density expected in the simulation experiments, the influences of space charge effect on modulation process have been confirmed in the view points of radial spread, axial velocity, and bunching characteristics.
