Demonstration of simulation capability on UKAEA’s Industry Simulation Software for Fusion case studies

UK Atomic Energy Authority · Tender notice on Find a Tender

Tender information last checkedLast checked 30 Sept 2026, 01:59.

Opportunity overview

Industry provides simulation software and methods covering a wide range of capability, deployed across all engineering sectors, much of which will be invaluable for use in the design and operation of fusion reactors in a Fusion energy industry. However, the extent to which existing capability is sufficient to facilitate design and realisation of commercial fusion powerplants is not clearly defined. Industry Simulation Software for Fusion is a multi-year rolling project aiming to define Fusion relevant analysis and simulation case studies and use them as a formal basis to engage industry for evaluation of their simulation software capability and identify development needs. The case studies to be submitted will span the full range of domains relevant to realisation of fusion as an energy source, with a mixture of single and multi-domain scenarios and involving use of a variety of methods and techniques. A total of four case study areas are covered in this procurement exercise.
