The Nuclear Regulatory Commission issued an Environmental Assessment and Finding of No Significant Impact for the renewal of Facility Operating License No. R-129 held by the University of Texas at Austin, authorizing continued operation of its 1.1 MW(t) TRIGA Mark II research reactor at the J.J. Pickle Research Campus in Austin, Travis County, Texas. The proposed renewal carries no fixed license term. The NRC found no significant radiological or non-radiological impacts: Ar-41 releases averaged a dose of about 0.01 mrem/yr to the public over 2020-2024, far below the 100 mrem/yr limit, and no physical changes to the facility are proposed. The only alternative analyzed is denial of renewal, which would trigger decommissioning with similar environmental impact.1234
