Design, deliver, repeat: A formula for success in nuclear’s next era

Conditions for nuclear energy haven't looked this favorable in a generation. Policy support is building, public support has risen, and demand for reliable power continues to outpace what other sources can provide. Whether the industry can successfully capitalize on this moment will come down to how well it executes.

The proven truth is that execution success is largely determined before construction ever starts-by ensuring design constructability, shaping the project's execution plan, aligning design and delivery, and establishing the systems needed to control cost and schedule. Many large energy projects have faltered for lack of these engineering, procurement, and construction (EPC) fundamentals.

Bechtel has current projects across the full spectrum of nuclear development, including new AP1000 reactors in Poland, America's first utility-­scale Gen III+ small modular reactor for the Tennessee Valley Authority at Clinch River, Tenn., and TerraPower's first Natrium plant in Wyoming.

Whether for gigawatt-­scale Gen III/III+ reactors or smaller, stackable, next-­gen designs, success hinges on disciplined EPC processes; integrated planning; and proven digital, workforce, and supply chain strategies that are scaled as the project demands. When these are in place up front, performance improves dramatically and continues to improve project over project.

The energy industry has seen this before. Over the past two decades, the liquefied natural gas sector faced a challenge reminiscent of what nuclear is facing today: how to deliver an unprecedented volume of complex, capital-­intensive infrastructure on compressed timelines. Bechtel learned from that effort, having built approximately one-­third of the world's and more than one-­half of America's LNG export capacity. The answer is execution discipline applied systematically across successive projects.

Recent nuclear experience bears this out. Vogtle Units 3 and 4, America's first new commercial nuclear reactors in three decades, struggled with schedule delays and cost overruns. Once integrated sequencing was established, design maturity was prioritized to reduce rework, work was broken into trackable packages, and material deliveries were synchronized to field needs, tangible results were achieved.

In fact, Unit 4 was built nearly 30 percent more efficiently than Unit 3. Those gains were not driven by changes in reactor technology but by knowledge earned over time. Speed is not achieved through shortcuts but rather through standardized processes, mature supply chains, trained workforces, and learning curves carried forward from one project to the next.

These approaches are fully scalable to projects of any size and type. For example, to deploy hundreds of thousands of solar modules across hundreds of acres, a digital execution approach that combines design data, schedules, as-­builts, machine control feedback, drones, and mobile field inputs into a single shared view enables improved safety, quality, and schedule performance.

A similar data-­driven execution system is now reflected in the approach we are employing on the Natrium project with TerraPower. TerraPower and Bechtel began collaborating at the earliest stages to optimize the design and the way the plant would be built. That early integration allows advanced technology to be paired with modular execution and digital delivery tools, resulting in a nuclear project designed from the outset to be safer, faster to construct, and repeatable.

Nuclear's next era will be defined not just by improved technology but by improved execution systems-and execution improves when projects are designed for delivery from the beginning. This calls for leaner planning, early integration, and digital execution built to scale, again and again.
