The UK Atomic Energy Authority (UKAEA)'s fusion energy experiment - the Mega Amp Spherical Tokamak (MAST) Upgrade tokamak at Culham Science Centre - has achieved first plasma for the first time. MAST Upgrade will be the forerunner of the UK's prototype fusion power plant - Spherical Tokamak for Energy Production (STEP) - due for completion by 2040. It will also aid preparations for Iter - the world's largest science megaproject, under construction in the South of France, which intends to demonstrate fusion power on an industrial scale.

The UKAEA said the device, which has taken seven years to build at the Culham Centre for Fusion Energy near Oxford, will take the UK closer to delivering fusion energy and will be a vital testing facility for delivering the Step fusion power plant. Step (Spherical Tokamak for Energy Production) is due for completion by 2040.

Fusion energy offers the potential of an abundant, inherently safe low-carbon electricity supply. It involves fusing hydrogen particles in a hot gas known as a plasma to unlock large amounts of energy.

Operating fusion technologies requires a careful balancing act of controlling extreme heat, gas and powerful magnetic fields, amongst other complex systems.

Assystem’s Sunderland engineering team will lead two crucial aspects of the UK’s STEP (Spherical Tokamak for Energy Production) fusion project – Breeder Blanket and Materials Database, Assystem said on 20 December. STEP is being designed at the UK Atomic Energy Authority’s (UKAEA’s) site at Culham in Oxfordshire. Assystem’s team of engineers will be contributing from their bases in Sunderland, Derby and Blackburn. Assystemhas experience delivering fusion projects including leading the design of the Divertor Remote Handling System (DRHS)  for the International Thermonuclear Experimental Reactor (ITER), under construction in France. The DRHS is a robotic arm that can operate inside the extremely hot environment of the fusion reactor.

David Kingham, CEO of UK based Tokamak Energy says experimental and theoretical research has shown 'spherical' tokamaks to be a "fast route to fusion" compared with more "conventional" tokamak devices such as Joint European Torus (JET). He was addressing a 25 January International Energy Agency (IEA) meeting on fusion power. Tokamak Energy was invited to the meeting as "one of the three most promising fusion concepts", along with General Fusion and Tri-Alpha Energy.

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
