North American construction is back—smaller and faster—at OPG’s Darlington
“The nuclear renaissance is real here,” said Ontario Power Generation’s Subo Sinnathamby on May 8, one year to the day after OPG secured a final investment decision to build the first of four planned BWRX-300 reactors at its Darlington nuclear power plant, and shortly after the new reactor’s foundation was lifted into place. “We got our license to construct in April and our [final investment decision] in May, and we’ve been off to the races since.”

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.
