Nuclear fusion research. MAST (Mega Amp Spherical Tokamak) device undergoing maintenance. The MAST device can confine a hot plasma for use in fusion research. The plasma it produces is spherical instead of the usual torus (ring) shape. It is situated at UKAEA (United Kingdom Atomic Energy Authority) in Culham, Oxfordshire, England. It is part of the EFDA (European Fusion Development Agreement) initiative to research and investigate the viability of fusion power. Nuclear fusion is the joining (fusing) of light elements to form heavier elements, which releases large amounts of energy. It is hoped that fusion will be a clean, renewable energy source for the future.
