Older Inspection Reports

TRTR Facility Special Inspections

University of Texas – Austin Nuclear Engineering Teaching Laboratory – 2022
- A Special Inspection was performed from November 7 – December 8, 2022 to investigate the operation of the reactor with aluminum clad fuel elements in the core, contrary to the reactor license. One Severity Level IV violation for failure of the Reactor Safety Committee to review changes to the facility was identified. One apparent violation was identified for the operation of the reactor with an aluminum clad fuel element in the core.
  - Relevant Documents: ML22307A305, ML22333A623, ML23067A209, ML23067A196, ML23129A243
NIST Center for Neutron Research – 2021
- A Special Inspection was performed from February 9, 2021 – March 16, 2022 in response to an apparent Safety Limit violation leading to partial melting of a fuel element and release of fission products. The NRC identified 7 apparent violations related to exceeding the fuel temperature Safety Limit, emergency planning, and unauthorized changes to the facility.
  - NRC Webpage
Purdue University Reactor – 1 – 2020
- A Special Inspection was performed from October 27 – November 6, 2020 to investigate the operation of the Purdue Research Reactor above its maximum licensed power level following the installation of the new control system. 2 violations were identified and categorized as a Severity Level III problem.
  - Relevant Documents: ML20311A264, ML20337A106, ML20337A104, ML20337A105, ML20330A231, ML20336A324, ML21035A014, ML21035A348, ML21181A403, ML21294A279
Rhode Island Nuclear Science Center – 2012
- A Special Inspection was performed at the Rhode Island Nuclear Science Center from October 26-27, 2011 to follow up on an event that lead to a worker receiving a dose of approximately 2.5 Rem. The worker entered a dry irradiation room after the reactor core had been moved adjacent to the room and the dose rate was approximately 30 rem/hr. This was determined to be a Severity Level IV violation, but was not cited as RINSCs corrective actions were deemed appropriate.
  - Relevant Documents: ML111313A012
NC State University PULSTAR Reactor – 2011
- A Special Inspection was performed at the NC State University PULSTAR Reactor to follow up on a technician entering a neutron radiography cave with a shutter open while the reactor was operating and being exposed to dose rates of approximately 30 rem/hr. Additionally, the technician was not wearing dosimetry. This was determined to constitute 2 Severity Level IV violations, but was not cited as NC State’s corrective actions were deemed appropriate.
  - Relevant Documents: ML103620450
Kansas State University TRIGA Reactor – 2010
- A Special Inspection was performed at the Kansas State University TRIGA Reactor to investigate the circumstances of an event leading to unexpected high dose rates in excess of 20 rem per hour. Irradiated oil samples were removed from the reactor pool resulting in unexpectedly high dose rates in excess of 50 rem per hour. A Severity Level III violation was issued for failure to perform required surveys and issue proper dosimetry to personnel.
  - Relevant Documents: ML102810336, ML102860039, ML102810019
Massachusetts Institute of Technology Reactor – 2007
- A Special Inspection was performed at the MIT Nuclear Reactor Laboratory to investigate the circumstances which lead to an employee receiving an unexpected whole body dose of approximately 4 Rem during the third quarter of 2007. This dose was found to result primarily from silicon doping operations at the facility. 2 Severity Level IV violations were issued for failure to perform required surveys and failure to provide proper training to personnel issued dosimetry.
  - Relevant Documents: ML080230720
Texas A&M Nuclear Science Center TRIGA Reactor – 2006
- A Special Inspection was performed at the Texas A&M Nuclear Science Center to investigate the potential extremity overexposure to a worker. The event was not determined to be an overexposure, but it was found that the worker had failed to follow procedures. A Severity Level IV violation was determined to have occurred for failure to make required surveys.
  - Relevant Documents: ML061230077, ML061570264
