Idaho Congressman Simpson Secures Hundreds of Millions for Idaho National Laboratory in House Appropriations Bill
Idaho Congressman Mike Simpson has secured substantial federal funding for the Idaho National Laboratory (INL) as part of the Fiscal Year 2027 Energy and Water Development Appropriations Bill, which cleared the House Appropriations Committee on June 1, 2026.
The legislation directs $392 million toward INL infrastructure improvements, a significant commitment to one of East Idaho’s most consequential federal installations. The bill also allocates $40 million for the Microreactor Application Research Validation and Evaluation project and $65 million for the National Reactor Innovation Center. Additional provisions in the measure support advanced reactor technologies and broader nuclear research programs.
Simpson Calls Funding an Investment in National Security and Energy
Rep. Simpson, who represents Idaho’s 2nd Congressional District and serves on the House Appropriations Committee, framed the funding as critical to both domestic energy development and U.S. security interests. “Enhancing the Lab’s infrastructure and growing research are investments in both energy and national security,” Simpson said in remarks tied to the bill’s committee passage.
INL Director John Wagner also weighed in, expressing appreciation for Simpson’s work on the appropriations measure and underscoring the significance of sustained federal backing for the nation’s nuclear research capabilities, according to the press release accompanying the funding announcement.
The Idaho National Laboratory, located west of Idaho Falls in Bonneville County and beyond, serves as the country’s leading nuclear energy research institution. It employs thousands of workers across East Idaho and contributes substantially to the regional economy. Federal appropriations directly shape the lab’s capacity to conduct long-range research, maintain aging facilities, and develop next-generation reactor technologies.
Microreactors and the National Reactor Innovation Center
Two of the targeted funding items — the Microreactor Application Research Validation and Evaluation project and the National Reactor Innovation Center — reflect a broader federal push to accelerate the development of advanced and small modular reactor designs. These programs are central to INL’s mission of moving experimental nuclear technologies from the research phase toward practical deployment.
The National Reactor Innovation Center in particular is designed to give developers of new reactor concepts a pathway to test and demonstrate their designs using INL’s infrastructure. Proponents argue this kind of public-private collaboration is essential to restoring American leadership in civilian nuclear energy at a time when foreign competitors are actively expanding their own nuclear programs.
The $40 million earmarked for the microreactor validation project supports efforts to evaluate how small, portable reactors could serve remote locations, military installations, and communities where traditional grid power is unreliable or unavailable. Idaho has been at the forefront of these programs, with INL hosting several demonstration projects in recent years.
What Comes Next
The House Appropriations Committee’s approval marks a significant early step, but the bill must still advance through the full House, then clear the Senate and any conference process before becoming law. Negotiations over the final funding levels could shift individual line items before a final version reaches President Trump’s desk.
For Bonneville County and the broader East Idaho region, the stakes are considerable. INL’s workforce, its associated contractors, and the ancillary businesses that support the lab’s operations collectively represent a major pillar of the local economy. Sustained federal investment at the levels Simpson secured in committee would support facility upgrades and research hiring for years to come.
Simpson has long championed INL funding as a core part of his congressional work. His seat on the House Appropriations Committee gives Idaho direct leverage in shaping the federal budget lines that determine the lab’s annual resources.
