    Brief

    STEP programme seeks suppliers to develop reactor-scale vapour shielding modelling to assess plasma transient effects on plasma-facing components. The work comprises four phases: Phase A (required for proposals) evaluates limiter strike scenarios and architecture risks; Phase B (optional pricing) expands analysis of transient scenarios, material degradation, and mitigation strategies; Phase C (optional pricing) develops engineering models and lifetime assessments for plasma-facing components; and Phase D (future, no pricing) assesses combined transient hazards for protection system design. Suppliers must demonstrate proven access to established reactor-scale vapour shielding modelling frameworks. Work progresses through successive phases based on technical results, funding availability, and STEP programme priorities. Proposals should be submitted via the eSourcing portal.
