Where Reactor Science Meets Innovation
The TRTR Annual Conference is the preeminent gathering of professionals, researchers, and students working with test, research, and training reactors across the United States.
Hosted by the Nuclear Engineering Teaching Laboratory (NETL) at The University of Texas at Austin, the 2026 conference will feature technical sessions, facility tours, workshops, and networking opportunities spanning the full breadth of research reactor operations, science, and policy.
Conference Topics
We invite submissions covering all aspects of research, test, and training reactor science and operations (see examples).

Texas' Advanced Nuclear Capital
Austin has emerged as a de facto headquarters for the advancing nuclear renaissance — home to a unique concentration of industry advocacy bodies, state policy offices, reactor developers with active manufacturing facilities, and a research reactor with license renewal progressing in a rapidly changing environment. No city outside the traditional federal laboratory corridors can match this density of nuclear activity.
Prototypes, test platorms, new reactor concepts, and fast builds are a pressure test for safety standards and quality assurance systems that are the core of legacy nuclear safty culture. This conference the center of active development is a timely reminder that shared expertise, experience, and research of the Test, Research, and Training Reactor community has an important role as the nuclear industry moves forward.

Natura Resources
An Abilene, Texas-based molten salt SMR developer. Natura selected Abilene Christian University to lead the Natura Resources Research Alliance — a four-university consortium including Texas A&M, UT Austin, and Georgia Tech — to design, license, and build a molten salt research reactor on ACU's campus in Abilene. The NRC construction permit was issued to ACU, making it the only NRC construction permit for a liquid-fueled reactor design in U.S. history.

Atomic Alchemy — Groves Isotopes Test Reactor
A wholly owned subsidiary of Oklo (NYSE: OKLO), Atomic Alchemy is building the Groves Isotopes Test Reactor — a light-water-cooled, pool-type Versatile Isotope Production Reactor (VIPR) — in Caldwell County, Texas, as part of the planned Proto-Town Innovation Hub. The DOE approved their Nuclear Safety Design Agreement under the Reactor Pilot Program in March 2026, and the company is targeting criticality by July 4, 2026 — potentially making it operational before the TRTR conference. The facility is designed to produce isotopes for cancer diagnosis and treatment, advanced manufacturing, scientific research, space exploration, and national security, and will serve as a pilot for a planned multi-reactor isotope foundry.
