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).”

The paper summarizes recent advances in physics of multiple-mirror confinement. GOL-3 in Novosibirsk is the only existing large-scale device of this type. Achieved plasma parameters are: n ~ 1021 m-3, T ~ 2 keV, E ~ 1 ms. Intense experimental and theoretical studies revealed several new collective phenomena that radically change plasma behavior in the trap as compared to simple classical theory. These phenomena are intrinsically linked to the second major feature of GOL-3, namely, fast plasma heating by a high-power relativistic electron beam. Collective beam-plasma interaction delivers energy to plasma through strong Langmuir turbulence and changes other plasma properties as well. In particular, the turbulent plasma in GOL-3 features suppressed axial heat transport, fast collective heating of ions, limitation of axial particle loss, and MHD stabilization by a magnetic shear. Mentioned phenomena greatly improve prospects of multiple-mirror confinement for fusion reactor applications. An outlook for possible fusion-scale device is presented.
