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.

🔬
New for 2026 — If the Community Says Yes
Research Reactor Applications Forum
A proposed new format for TRTR: cross-sector dialogue sessions connecting reactor facilities, researchers, industry, and agencies to promote where research reactors can contribute to external needs and communication where a facility has developed an application, capability, or practice that could be useful at other facilities. Whether this becomes part of the 2026 program depends on community interest. See the concept and weigh in →

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.

Research Reactor Applications Forum

💬
A Note on This Program
The Research Reactor Applications Forum is a new concept for TRTR — and whether it becomes part of the 2026 program depends on whether the community wants it. If we receive enough expressions of interest from across the reactor, research, and industry communities, we'll build the program. If the interest isn't there, we won't. Your submission — whatever your role — is a vote for this format. We'll announce by late July 2026 whether the Forum will proceed, and if so, which topics move forward to be shaped by the community priority ranking.

Structured conversations across the reactor, research, and industry communities discussing where research reactors can contribute or share information, and where barriers may have limited collaboration.

Across radiation effects testing, medical isotope production, materials research, and other domains, research reactor capabilities are not always visible to the communities that could use them. In some cases the connection simply hasn't been made. In others, assumptions about what research reactors can deliver may not reflect current reality. Research reactors continually seek and develop innovations for operations, maintenance, and research capabilities that could result in safer and more efficient operations across the community — knowledge that does not always travel beyond the facility where it was earned. The Research Reactor Applications Forum is designed to build those connections and close those gaps.

These will not be paper presentations. Each Forum session will be a structured conversation designed to bring together reactor operators, external researchers, agency program managers, and industry partners — anyone with a stake in whether these capabilities and innovations reach the people and programs that could benefit from them. The goal is matchmaking, knowledge transfer, and peer learning: connecting reactor facilities with external communities that haven't found their way to the table and sharing lessons from reactor-to-reactor. Sessions will be held after the main technical program concludes, giving every attendee the opportunity to participate regardless of their conference schedule.

⚛️ Reactor Facilities

Share what your facility can do, what you've learned building a capability, and what a similar program might look like elsewhere. Or ask — if another facility has developed something that would benefit the community, this is the place to surface that conversation. Not a paper — an honest working exchange.

🔬 Researchers & Industry

If you have a testing, irradiation, or isotope need — or if you've written off research reactors based on assumptions about what they can deliver — this session is for you. Bring your problem.

🏛️ Agencies & Programs

Program managers and agency representatives are essential voices here. If you fund work that touches reactor-based testing or production, your perspective on what's working — and what's missing — shapes the conversation.

Example Forum Topics
OFFERED
Reactor Digital Twins — Architecture, Data Infrastructure & Lessons Learned
UT-NETL shares the development path for their TRIGA digital twin: required data streams, physics-informed modeling, real-time control integration, and a candid look at what they would do differently from day one.
OFFERED
Radiation Effects Testing: What Research Reactors Can Actually Deliver
A direct response to the misconception that research reactors can't produce fields relevant to radiation effects work. Covers flux and dose rate ranges, dosimetry standards, test reporting, and how to engage facilities — with perspective from both reactor operators and end users.
OFFERED
Isotope Production — Pathways, Progress & What's Changed
Medical isotope production at research reactors is gaining traction after years of stagnation. A discussion of what's changed, where opportunities exist for facilities at different scales, and what the licensing and commercial landscape actually looks like today.
PROPOSED
Where Are the Gaps? Application Domains Where Research Reactors Could Contribute More
An open roundtable to identify application areas — beyond the well-known ones — where embedded assumptions or lack of awareness may have limited collaboration. Radiation effects and isotope production are starting points, not endpoints.
PROPOSED
Collaborations That Work — and What Made Them Work
Successful partnerships between reactor facilities and external users — in radiation testing, materials research, or other domains — share their stories with an explicit focus on what it took to get there and what others would need to replicate it.
PROPOSED
University–National Lab Partnerships — MOUs, Shared Use & Joint Staffing
Structuring durable partnerships: how to negotiate shared-use agreements, manage IP, co-hire personnel across institutional boundaries, and maintain alignment when priorities diverge.
How the program comes together
  1. Submit an expression of interest — use the form below. Whether you're a reactor facility, an external researcher, an industry partner, or an agency representative, tell us what you'd bring or what you need.
  2. Community input — proposed topics are shared with attendees for feedback. Topics with broad cross-sector interest rise to the top.
  3. Program committee review — the committee matches interests, recruits additional voices where needed, and designs sessions for genuine dialogue — not one-way presentations. You'll be notified of your session's structure by email.
  4. Confirmed sessions appear below — accepted Forum sessions are listed here and included in the printed program.
  5. Attend what matters to you — sessions run in parallel after the main technical program. All registered attendees may attend any Forum session.

  • Assess realistic staffing, licensing, and budget requirements for initiating a similar program at your facility.
  • Review integration challenges with legacy control systems and how they were addressed at UT-NETL.
  • Identify agency and national laboratory partners that can accelerate digital twin development for research reactors.
