New nuclear projects face a narrow opportunity to prove they can be executed differently than the last generation of U.S. builds. Lessons from Vogtle and V.C. Summer show that extreme cost and schedule overruns were driven by governance failures, weak processes, and unmanaged risks. This white paper presents MCR’s proven framework to quantify risks early, strengthen ownership, and provide leaders clear visibility into project health. MCR’s approach reduces project contingency requirements and avoids surprise cost and schedule impacts.
