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 Nuclear Research and Consultancy Group (NRG) of the Netherlands has completed the irradiation testing in the High Flux Reactor of a new type of metal that will be used in a test programme of the International Thermonuclear Experimental Reactor (ITER).

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.

The UK Department of Energy & Climate Change has a problem with the world’s largest stocks of reactor-grade plutonium. The international association Environmentalists for Nuclear Energy view this as a one-time opportunity to benefit several advanced nuclear energy developments, none of which are acknowledged by DECC. By Brendan McNamara

Weak, short distance radiation makes it warm; so it is safe to hold but not to swallow. UK reactor grade plutonium is unsuitable for making weapons. And small-scale uses of UK plutonium could never go critical
