U.S. Secretary of Energy Chris Wright toured next-generation small modular nuclear reactors at the Idaho National Laboratory [1].

The project represents a strategic shift toward smaller, more flexible nuclear power to reduce national reliance on fossil fuels. Backers said the initiative is a turning point for the nuclear industry as the U.S. seeks to expand its clean-energy capacity [3].

The tour took place on June 25, 2026 [2], at the facility near Idaho Falls, a location often called “Atomic City” [1]. The site serves as the primary proving ground for these reactors, which are designed to be more efficient and easier to deploy than traditional large-scale nuclear plants.

Funding for the reactor program has reached billions of dollars [4]. This investment comes from a combination of government grants and private industry backers who are betting on the commercial viability of small modular designs.

There is some variation regarding the current status of the technology. Some reports said the reactors are already up and running or nearly so [4], while other accounts said the new generation is poised to come online within the next few years [1]. Regardless of the exact operational date, the Idaho site is providing the necessary demonstration and testing required for a broader rollout.

These reactors differ from older models by using modular construction, which allows components to be built in factories and shipped to sites for assembly. This approach aims to lower costs and shorten the timeline for adding new power sources to the grid.

“The project represents a strategic shift toward smaller, more flexible nuclear power.”

The transition to small modular reactors (SMRs) suggests a move away from the massive, multi-decade construction projects that have historically hindered U.S. nuclear growth. By utilizing factory-based manufacturing and government-backed testing grounds like the Idaho National Laboratory, the U.S. is attempting to lower the financial risk of nuclear energy to make it a competitive pillar of the carbon-free energy transition.
