  • Project delivery capability is advancing with groundbreaking at INL, active earthworks, engagement of Kiewit as constructor, and completion of full-scale fuel assembly flow testing.
  • Strategic ecosystem building through partnerships with ABB, Vertiv, KHNP, Blykalla, newcleo, and federal agencies aims to reduce cost, schedule, and supply chain risk across deployment and operations.
  • Vertical integration in fuel supply is progressing via the Tennessee Advanced Fuel Center plan and DOE-backed A3F approvals, positioning the company to mitigate fuel availability risks and stabilize costs.
  • Evidence lacking: Quantified project-level milestones, detailed capex schedules, cost-to-complete estimates, and realized ROI/KPI frameworks are not provided.
