Maintenance and material aspects of DREAM reactor

Efficiency and availability driven R&D issues for DEMO

“…Alternative maintenance schemes based on blanket segmentation in a lower number of elements have been considered in a number of reactor studies, in particular for the PPCS [3], ARIES-RS [56] and DREAM [57]. An earlier comparison of these concepts [59] has concluded that the availability of a reactor adopting any of these concepts would be around 65% and that, assuming some improvements, such schemes should be acceptable for a first generation of fusion power plants.…”

Characterizations of pulsed laser deposited SiC thin films

“…A large set of promising electrical, optical and mechanical properties possessed by SiC makes it a very attractive candidate for high power, high temperature and high frequency applications even under the harsh environmental radiation and chemical conditions [1][2][3][4][5]. Among the various possible crystalline structures of SiC, also known as polytypes, cubic SiC phase (3C-SiC or b-SiC) is of particular importance owing to its high mobility (1000 cm 2 /Vs), electron saturation drift velocity (2.2 · 10 7 cm/s), high resistance to oxidation, high thermal conductivity and low expansion coefficient.…”
