A Chinese tokamak device has set a new world record for a steady-state high-constraint mode plasma operation and German researchers have discovered a way to build smaller and cheaper fusion reactors. Meanwhile a US Government Accountability Office report on achieving commercial fusion cautions that several challenges must still be overcome.

The Korean Superconducting Tokamak Advanced Research (KSTAR), a tokamak nuclear fusion reactor, achieved a world record of 70 seconds in high-performance plasma operation, South Korea's National Fusion Research Institute (NFRI) said in a statement on 14 December. NFRI said a fully non-inductive operation mode - a "high poloidal beta scenario" - had been used to achieve this long and steady state of operation using a high-power neutron beam. It said various techniques, including a rotating 3D field, had been applied to alleviate the accumulated heat fluxes on the plasma-facing components.
