ARIES-ST is a 1000 MW fusion power plant conceptual design based on a low a
spect ratio 'spherical torus' (ST) plasma. The power core uses an advanced
'dual-cooled' breeding blanket with flowing PbLi breeder and He-cooled ferr
itic steel structures. The main features of the blanket design are summariz
ed here together with analysis of the thermal hydraulic and thermomechanica
l performance. (C) 2000 Elsevier Science B.V. All rights reserved.
