Do you trust your state government to regulate radioactive materials as effectively as federal agencies?
Starting September 30, 2026, the Indiana Department of Homeland Security will officially manage 213 radioactive materials licenses previously overseen by the U.S. Nuclear Regulatory Commission. This shift makes Indiana the 41st state to enter a regulatory agreement with the federal government.
Why it matters
State leadership expects this transition to reduce administrative barriers and shorten permit review times for businesses. The move is designed to accelerate the development of small modular reactor energy technology within Indiana.
Indiana is assuming authority over 213 radioactive material licenses, representing a fraction of the roughly 1,800 licenses managed by the NRC. The transfer follows a four-year process of aligning state laws with federal standards.
The players
Indiana Department of Homeland Security
The state agency tasked with managing emergency preparedness and, as of September 30, 2026, the state's Radioactive Materials Control Program.
U.S. Nuclear Regulatory Commission
The federal agency responsible for regulating commercial nuclear power plants and the possession, use, and disposal of radioactive materials.
Mike Braun
The Governor of Indiana who formally requested the regulatory transfer from the federal government.
The details
The Indiana Department of Homeland Security will administer these responsibilities through its Radioactive Materials Control Program. This program manages licensing and enforcement duties previously handled by the NRC, which oversees roughly 10 percent of the 18,000 total active radioactive material licenses in the U.S. State officials finalized their regulatory framework for this transition on November 26, 2025.
Timeline
2022: Governor Holcomb signed Senate Enrolled Act 381 into law.
November 26, 2025: Indiana published the final radioactive materials regulation rule.
January 29, 2026: Governor Braun requested the radioactive materials agreement.
September 24, 2026: Governor Braun and the NRC Chairman signed the agreement.
September 30, 2026: The radioactive materials regulation agreement takes effect.
The Tech Race
Indiana joins the existing framework of Agreement States that have transitioned from federal to local oversight of radioactive materials. The move follows a pattern set by the NRC's Agreement State program, which allows states to assume federal regulatory authority.
Businesses working with radioactive materials in Indiana should prepare for a change in their licensing and enforcement point of contact starting September 30. The state aims to lower regulatory fees and speed up review processes compared to the federal system.
The takeaway
This agreement signals Indiana's commitment to creating a streamlined regulatory environment for nuclear technology startups. Industry observers should monitor the state's future permit processing speeds to see if the promised reduction in red tape manifests.
