MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT I. INTRODUCTION The University of Maryland Training Reactor (MUTR) is an, open-pool type, TRIGA fueled reactor licensed for operation at 250 kW thermal power. The core is cooled by natural convection of the pool water with auxiliary cooling provided for protection of the filters and ion exchange equipment associated with reactor support piping.
The MUTR is used for academic instructions and operator training, performance of neutron and gamma irradiations, neutron activation analysis experiments, and tours and demonstrations for groups internal and external to the campus as well as for visiting nuclear power plant trainees.

MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT REACTOR USEAGE During the past year the MUTR operated for a total of 72 runs (Run Numbers 3917 - 3988),
which are categorized below:
Operator Training/Requalification* 26 runs Tours, Labs & Demonstrations 14 runs Calibration, Maintenance, and Surveillance 15 runs Irradiations and Activations 17 runs
- Note: Some runs involved training and surveillance and may be counted in both categories.
- Note: Some of the runs in the Classes category consisted of irradiations. They are not included in the Irradiations category.
To perform these runs the core produced 15.298 MWh (kWh meter change from 244583 kWh to 259881 kWh), with a corresponding bumup of 0.87 Grams of U-235.

MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT III. SURVEILLANCE TESTS AND INSPECTIONS All required surveillance tests and inspections were performed at the specified intervals. The required surveillance items for this reporting period include:
WATER SAMPLE TESTS AIR SAMPLE TESTS RADIATION SURVEYS CONTROL ROD DROP TEST RAM CALIBRATION SNM INVENTORIES ALARA REVIEW In addition to the above surveillance items, the following maintenance operations were performed on the indicated dates:
9/30/08 Dri-rite baked. (Run 3937) 12/09/08 Dri-rite replaced. (Run 3950) 3/05/09 Dri-rite baked. (Run 3964) 6/12/08 Dri-rite replaced. (Run 3985)
Additional minor maintenance was performed such as light bulb replacement and fine-tuning of equipment was performed as necessary.

MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT IV. CHANGES TO FACILITY There were no significant changes to the Facility during this reporting period.

MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT V. ENVIRONMENTAL SURVEYS OF SURROUNDING AREAS All continuous monitoring for this year was accomplished using fixed-mounted film badges throughout the interior of the reactor building itself. These badges recorded the follovwing exposures:
Monitor Location Dose (mrem) 1 Control Room 94 2 Pool Surface 541 Hot Room 353 4 Prep Room 131 5 S. Wall Upper 22 6 S. Wall Lower 76 7 E. Wall Lower 94 8 Pump Room 330 9 N. Wall Lower 1425 10 W. Wall Lower 342 6
MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT VI. RADIOACTIVE RELEASE AND DISCHARGE TO THE ENVIRONMENT The Reactor Storage Sump was not discharged during this reporting period.
The only release from the MUTR consists of Ar-4 1. From Section 11 of the SER for the MUTR, a 15.3 MWh operation year would result in the generation of 60.9 mCi of Ar-41 for the entire year from the reactor pool tank. For this operational year, a combined 25.1 mCi of Ar-41 was released to the reactor building. This value was used in the EPA program COMPLY. The MUTR meets the EPA level 2 compliance for airborne release of radioactive materials. A copy of the output for the EPA computer program "COMPLY" is appended with this report.

MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT VII. ALARA REVIEW FOR FACILITY PERSONNEL AND VISTOR EXPOSURE A review of exposure records and all facility operations were performed by facility management as part of the annual ALARA audit. For this reporting period, all badged personnel and students received doses less than ten per-cent of their annual dose limit.
The Pocket Dosimeters recorded minimal exposure for all guests and service personnel.
Calibrations of these self-reading dosimeters were performed on an annual basis by the University of Maryland's Radiation Safety Office.
8
MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT VIII. UNSCHEDULED SHUTDOWNS/REPORATBLE OCCURRENCES No unscheduled shutdowns occurred during this reporting period.
There were no reportable occurrences during this reporting period.
9
MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT IX. SPECIAL EXPERIMENTS There were three special experiments performed during this reporting period. All three were duplicates of previously performed operations but required opening the thermal column and therefore by Operating Procedure 105 Revision 12 (OP105R12) section 3.3 were considered "Special Experiments". These experiments were conducted in a "standard" configuration with the thermal column plug in place but with small packages of wire of various materials used in standard flux and spectra determination. These experiments were operations 3978 (12May09),
3979 (13May09), and 3988 (29Jun09).
10
MARYLAND UNIVERSITY TRAINING REACTOR 2008-2009 ANNUAL OPERATING REPORT X. CHANGES IN FACILITY STAFF There were no significant changes to staffing during this reporting period with the exception of one RO (Ian Gifford) was upgraded to a SRO license and three additional ROs were added (Layla Shahamat, Anders Gilberston, and Paulette Torres).
