University of Florida Training Reactor Annual Progress Report September 1, 2012- August 31, 2013 Submitted by Brian Shea Reactor Manager University of Florida Gainesville, FL March 2014

Introduction As stated in the UFTR Technical Specifications, Section 6.6. 1:

Routine annual reportscovering the activities of the r'eactorfacilit, during the previous calendar year shall be submitted to the Commission within six (6) months Ibilowing the end of each prescribedyear. The prescribedyear ends August 31 for the UFTR. Each annual operating report shall include the following in/brmnation:

(1) a narrativesummary of reactor operatingexperience including the energy producedby the reactorand the hours the reactorwas critical (2) the unscheduled shutdowns including, where applicable,corrective actions taken to preclude recurrence (3) tabulationof major preventative and corrective maintenance operations having safety significance (4) tabulationof ma/or changes in the reactorfaciliti,andprocedures,and tabulationof new tests of experiments, that are significantly different from those performedpreviously and are not described in the Safety Analysis Report, including conclusions that no unreviewed safety questions were involved (5) A summary of the nature and amount of radioactive effluents releasedor dischargedto the environs beyond the effective control of the ficility operators as determined at or before the point of such release or discharge. (The summary shall include to the extent practicablean estimate of individualradionuclidespresent in the effluent. If the estimated average release after dilution or dýffusion is less than 25% of the concentration allowed, a statement to this effect is suficient.)

(6) A summarized result of environmental surveys petformed outside the facility.

(7) A summary of exposure received by facility personnel and visitors where such exposures are greaterthan 25% of that allowed The following discussion on the above seven sections covers the period from September 1, 2012 to August 31,2013, except as noted otherwise.

1. Summary of Reactor Operation Experience The UFTR was not operated during this reporting period.

2. Unscheduled Shutdowns The UFTR was not operated during this reporting period and there were no unscheduled shutdowns.

3. Safety Significant Major Maintenance Operations MLP 13-05, 4/29/2013 to 9/12/2013, Reactor Cell HVAC replacement. Replaced original HVAC unit and reduced confinement penetrations. Safety related function as described by the FSAR is unchanged.

4. Major Changes in Reactor Facility, Procedures and Experiments No major changes to procedures or experiments.

Completed the installation of a facility communications network.

Completed the installation of GTRI funded enhancements to the facility.

Completed the replacement of the Reactor Cell HVAC unit.

5. Radioactive Effluents Liquid Releases:

The UFTR is equipped with a waste water holdup tank. The radioactivity in the waste water is measured prior to release.

Table I Volume and Concentration of Waste Water Released Date Water Released (Gallons) Activity Released (gCi/mL)

November 1, 2012 932.4 < LLD Argon-41 Releases:

The Argon-41 release concentration is measured every six months during facility operation. The facility was not operated during this reporting period and therefore there were no measureable Argon-41 releases.

6. Environmental Surveys In addition to periodic radiation surveys using hand-held instruments, environmental monitoring is accomplished using radiation dosimetry badges. Areas monitored are located around the exterior of the reactor building and nearby buildings, including the Nuclear Sciences Center and the Journalism Building. This monitoring is performed by the Radiation Control Office of the Environmental Health and Safety Division at the University of Florida. The environmental dosimetry reports are tabulated and presented in Table II.

The environmental dosimetry badges closest to the reactor cell radioactive materials storage areas are at locations 1, 2, 5, and 7.
