چکیده انگلیسی
A robust water-cooled divertor target plate solution for DEMO has to date remained elusive. Common to all contemporary concepts is an interlayer at the boundary between the tungsten armour and the cooling structure. In this paper we show by design optimisation that an effectively designed interlayer can produce dramatic gains in power handling. By engineering the interlayer as part of the design study, it is found that divertor performance is enhanced by either a low conductivity 'Thermal Break' interlayer or an 'Ultra-Compliant' interlayer. For a 10Â MW/m2 surface heat flux we find that a thermal conductivity of 15Â W/mK and elastic modulus of 1Â GPa are effective. A design is proposed which passes linear-elastic code rules up to an applied heat flux of 18Â MW/m2.
