This Market Engagement Notice seeks engagement with organisations capable of delivering reactor-scale vapour shielding modelling to support the STEP prototype powerplant programme. The work will investigate vapour shielding effects arising from transient plasma events and their impact on plasma-facing components, informing design, protection systems, and operational strategies. The scope is divided into four sequential phases covering: (A) initial assessment of limiter strike scenarios and architecture risks; (B) expanded analysis of transient scenarios, material degradation, and mitigation strategies; (C) development of engineering models and lifetime assessments for plasma-facing components and (D) assessment of combined transient hazards and their implications for protection system design. Suppliers must submit proposals for Phase A, with separate pricing for Phases B and C, while Phase D will focus on future capability without pricing at this stage. Suppliers are expected to demonstrate access to established reactor-scale vapour shielding modelling frameworks, with work progressing through successive phases subject to technical outcomes, funding availability, and STEP programme priorities.
