Description
Summary:•We analyse critically current capabilities and maturity levels of existing simulation tools relevant to fusion blanket physics and design.•The progress in the development of computational tools in each particular is found to be significant.•The requirements that need to be addressed for code integration are common to all areas and tools.•The integration into one single computational tool is currently premature and looser coupling ways need to be considered. Computer modelling is expected to play an increasingly important role in fusion design and technology, where the complexity of the physical processes involved (plasma, materials, engineering), and the highly interconnected nature of systems and components (“system of systems” design), call for support from sophisticated and integrated computer simulation tools. In this paper, we review the contribution of coupled computer modelling to the design of the reactor, breeding blanket and integrated first wall in terms of neutronics, materials behaviour (including plasma-materials interaction, radiation effects and compatibility with fluids), magnetohydrodynamics thermofluid issues and thermo-hydraulic aspects, as well as simulations of plasma transport out of the confinement region to determine heat and particle loads on plasma facing components. The current capabilities and levels of maturity of existing simulation tools are critically analysed, having in mind the possibility of integrating several tools in a single computational suite in the future and highlighting the perspectives and difficulties of such an endeavour.
