Cost overruns and delays in Nuclear New Build (NNB) are not inevitable, but they are common when lessons from previous projects, advanced technologies, and workforce planning are not integrated into one coherent strategy. Effective NNB projects use past construction experience, proven technology, and a carefully phased workforce plan to improve schedule and cost performance, but there is no single universal project management or business model because each country and project has different regulatory, financial, and contractual conditions.

A more efficient global nuclear supply chain depends on clear long‑term policy signals, harmonized standards, transparent supplier qualification, and early coordination among vendors, constructors, and operators so that the right components and skilled people are available at the right time.
