STEP Vapour Shielding Scenario Simulation

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) e...
