Query: Pulsed DEMO design assessment studies   Now that ITER is under construction, interest is increasing in the
specification and design of the successor machine, a Demonstration Power Plant
(DEMO), which in Europe is coordinated by the EFDA Power Plant Physics and
Technology programme. This paper summarises the work carried out for EFDA in
2011-2012 on design issues pertinent to a pulsed version of DEMO, intended to
be implemented with little or no extrapolation of technology available today.
The work was carried out by the Euratom Fusion Associations CCFE, CEA, CRPP,
ENEA and KIT, and in addition to a review of recent relevant literature
addressed systems code analyses (pulse length vs. size), erosion of plasma
facing components, thermomechanical fatigue in the blanket and first wall, a
range of energy storage issues, and fatigue life improvements in Nb3Sn CICC
superconductors.
