UNIVERSITY OF FLORIDA TRAINING REACTOR ANNUAL PROGRESS REPORT SEPTEMBER 1, 2006 - AUGUST 31, 2007 Submitted by Dr. Alireza Haghighat Interim Director of UFTR Department of Nuclear and Radiological Engineering University of Florida Gainesville, Florida February 2009

Introduction As stated in the University of Florida Training Reactor (UFTR) Technical Specifications, Section 6.7.1 Operating Report, routine annual reports covering the activities of the reactor facility during the previous calendar year shall be submitted to the Commission within' nine (9) months following the end of each prescribed year. The prescribed year ends A-ugu~t-31 for the UFTR. This annual operating report includes 7 sections:

(1) a narrative summary of reactor operating experience including the energy produced by the reactor and the hours the reactor was critical; (2) the unscheduled shutdowns including, where applicable, corrective actions taken to preclude recurrence; (3) tabulation of major preventive and corrective maintenance operations having safety significance; (4) tabulation of major changes in the reactor facility and procedures, and a tabulation of new tests or experiments, that are significantly different from those performed previously 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 released or discharged to the environs beyond the effective control of the facility operators as determined at or before the point of such release or discharge. (The summary shall include to the extent practicable an estimate of individual radionuclides present in the effluent. If the estimated average release after dilution or diffusion is less than 25% of the concentration allowed, a statement to this effect is sufficient.);

(6) A summarized result of environmental surveys performed outside the facility; (7) A summary of exposure received by facility personnel and visitors where such exposures are greater than 25% of that allowed.

The following discussion on the above seven sections covers the period from September 1, 2006 to August 31, 2007, except as noted otherwise.

1. Summary of Operation Experience In the past reporting year, UFTR continues to function as a reliable and productive facility with a broad range of research and educational utilizations by users within University of Florida as well as researchers and educators around-the State of Florida.

The generated energy and operation hours in this year are given as follows:

Energy generated: 4801.040 KWH Reactor Run Time: 202.50 hrs

2. Unscheduled Shutdowns ý) f.7 From September 1, 2006 to August 31, 2007 there were 3 unplanned shutdowns, each one summarized in the table below.

Reason Corrective Action 11/21/06: Coolant flow trip, accidental due Performed /2 hour of nitrogen flow without to nitrogen insertion.* trip indication at shutdown, and performed daily satisfactory checks.

5/30/07: Safety 2 power channel - apparent Troubleshoot, repaired safety 2 HV system.

high voltage trip, S2 HV apparent drop below 10% set point (Occurred 3 times, 6/8/07 and 7/26/07).

• 8/13/07: NE Fuel box high temperature.* Completed successful daily checks.

• NOTE: Filed as an Unscheduled Reactor Trip

3. Safety Related Maintenance Operations

1) 6/07: Dilution fan motor is replaced and the dilution fan is cleaned upon observing reduced dilution fan RPM

4. Major Changes in Reactor Facility, Procedures and Experiments None

5. Radioactive Effluents Liquid release:

2

UFTR is equipped with a waste water holdup tank. The tank is released two or three times per year. The radioactivity in the released water is measured.

Time period (mm.dd.yyyy) Water released (Gallon) Radioactivity released (uCi) 08.21.2006- 05.18.2007 816.2 1.54E-03 I..

J.

Argon-41 Release:

The Argon-41 release concentration is measured about every six months. The annual Argon-41 release is estimated by the measurement and operation hours. The Argon-41 release is

-24.3 mCi for FY 06 - 07. * /

6. Environmental Surveys The firm maintaining radiation records for the University of Florida keeps a year to date record, therefore it is easier to report radiation exposure by the nearest completed calendar year. The fOllowing film badge exposures are for the period January 1, 2006 to December 31, 2006. Thirteen areas (Numbered from 1 to 13) were monitored for the entire calendar year. A list of these numbered areas can be found in UFTR SOP. Among them, Area No. 2, which is the stack area, has the highest dose record. 3 separate areas in the reactor building were also monitored during the same time period. The area radiation exposures are tabulated below. All doses are in unit of mrem.

7. Radiation Exposures Note that UFTR TechSpecs requires only a summary of exposure received by facility personnel and visitors where such exposures are greater than 25% of that allowed. Since all personnel exposures during this period are below the limits, we provide an exposure summary for the UFTR staff.

The following table illustrates the radiation dosages of 4 workers for the period September 1, 2006 to August 31, 2007. All the dosages are in mrem.
