“…The CCFE analysis adopted a different approach, analysing the first wall rather than the blanket module and using a very simple (literature-based) model of the first wall structure of parallel tubes made from EUROFER 97, taking into account fatigue but not creep fatigue. 10 The coolant flow was modelled using computational fluid dynamics in order to determine the wall heat transfer coefficients and/or the temperature distribution. The parameters in the Coffin-Manson formula modeling the S-N curves for the structural alloy of interest (EUROFER) are needed to correct for the non-zero mean stress of this load case, but are not well-determined at present.…”

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 Nb 3 Sn CICC superconductors.
