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).”

At the L-2M stellarator, in the electron cyclotron resonance heating regime, the processes of plasma self-organization were studied in different successive phases of plasma confinement during the facility shot. It is shown that in the phase of initial plasma heating, because of the absence of plasma-wall interaction, the canonical pressure profiles of the electronic component are not formed. In the quasi-stationary phase, the forming pressure profiles are close to the canonical one, and the energy loss is somewhat higher than in the phase beginning immediately after switching off the microwave heating pulse. After turning off the microwave pulse, the self-organization processes form the canonical pressure profiles of the electronic component in plasma, which ensure minimal energy loss from the plasma. In this case, the total power of energy losses from the plasma is proportional to the cube of the plasma energy.
