Goals achieved:
• Funding
• HHRR training
• Licencing of non-heavy water reactor
• Supply chain development
• Construction/manufacturingbeginning
CAREM25 CURRENT STATUS
• Argentina is leading the PWR SMR design-construction process with the FOAK CAREM25
• Established supply chain for main local components
• Handful of lessons learnt not possible without the FOAK
• SMR cost structure knowledge
• Readiness for commercial plant based on the prototype design criteria. Economic asessment modules of ≈100MWe
