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.

NRG at Petten in the Netherlands is preparing to use its high-flux reactor (HFR) to test the operation, integrity and quality of the “first wall” that will shield the nuclear fusion process at the €15bn ($17bn) International Thermonuclear Experimental Reactor (Iter) under construction at Cadarache, France. Iter is intended to demonstrate the scientific and technological feasibility of fusion power. The project is being undertaken by seven members – Europe, the US, Russia, Japan, China, South Korea and India.

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
