Texas Uni's Nuclear Reactor Gets Green Light Renewal
Published Date: 3/11/2026
Notice
Summary
The University of Texas at Austin is getting the green light to keep running its nuclear research reactor for teaching and research. The Nuclear Regulatory Commission checked the environmental impact and found no big problems, so the license renewal is moving forward without extra costs or delays. This means students and researchers can keep using the reactor safely in Austin for years to come.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Reactor license renewed — research continues
The NRC is considering renewal of Facility Operating License No. R-129 to allow the University of Texas at Austin to continue operating its NETL TRIGA Mark II research reactor with no fixed license term. The license authorizes steady-state operation at 1.1 megawatt thermal (MW(t)) and pulsing up to about 1500 MW(t) (trip setpoint 1750 MW(t)), so students, faculty, and outside researchers can keep using the reactor for teaching, research, and isotope services.
No-action alternative would stop reactor services
If the NRC denied the license renewal (the no-action alternative), NETL TRIGA reactor operations would cease and decommissioning would be required, which would eliminate the reactor's education, research, isotope production, and public service activities that currently support UTA courses, student research, and outside researchers and industry.
NRC: public radiation exposures remain under limits
The NRC's environmental assessment found no significant radiological impacts from continued NETL TRIGA reactor operations. Conservative modeling gave a potential Ar-41 dose of 66 mrem/year (below the 100 mrem/yr limit in 10 CFR 20.1301), NETL reported annual Ar-41 releases no greater than 6.8 curies (about 0.01 mrem/yr), and perimeter monitoring from 2020–2024 measured exterior dosimeter results of about 1–5 mrem (Texas Department of State Health Services results ranged up to 28 mrem), all below the 100 mrem/yr public limit.
