13 1 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 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.2 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT REACTOR USEAGE During the past year the MUTR operated for a total of 48 runs (Run Numbers 3867 -3915), which are categorized below: Operator Training/Requalification*
13 runs Tours, Labs & Demonstrations 15 runs Calibration, Maintenance, and Surveillance 15 runs Irradiations and Activations 6 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 9.704 MWh (kWh meter change from 234687 kWh to 244380 kWh), with a corresponding burnup of 0.55 Grams ofU-235.3 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 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: 9/10/07 Dri-rite baked.12/03/07Dri-rite replaced 3/04/08 Dri-rite baked.6/15/08 Replaced air pump and Dri-rite.Additional minor maintenance was performed such as light bulb replacement and fine-tuning of equipment was performed as necessary.
Additional descriptions of some items from above can be found in Section IV.4 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT IV. CHANGES TO FACILITY There were no significant changes to the Facility during this reporting period.5 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 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 following exposures:

Wall Lower Dose (mrem)63 265 310 77 0 13, 49 227 1350 350 6 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 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 ofAr-41. From Section 11 of the SER for the MUTR, a 9.7 MWh operation year would result in the generation of 38.6 mCi of Ar-41 for the entire year from the reactor pool tank. For this operation year, a combined 15.9 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.7 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 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 2007-2008 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

SPECIAL EXPERIMENTS There were no special experiments performed during this reporting period.10 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT X. CHANGES IN FACILITY STAFF There were no significant changes to staffing during this reporting period.11 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT APPENDIX A: EPA COMPLIANCE Below is the output from the EPA program COMPLY for the Ar-41 release from the MUTR: COMPLY: Vl.5d.7/11/08 10:19 40 CFR Part 61 National Emission Standards for Hazardous Air Pollutants REPORT ON COMPLIANCE WITH THE CLEAN AIR ACT LIMITS FOR RADIONUCLIDE EMISSIONS FROM THE COMPLY CODE, VERSION 1.5d Prepared by: Maryland University Training Reactor University of Maryland College Park, MD 20742 Dr. Mohamad Al-Sheikhly (301) 405-5214 Prepared for: U.S. Environmental Protection Agency Office of Radiation Programs Washington, D.C. 20460 12 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT COMPLY: VI.5d.7/11/08 610:19 2007-2008 MUTR Annual Report Ar-41 Release SCREENING LEVEL 1 DATA ENTERED: Effluent concentration limits used.DATA ENTERED FOR STACK 1: Nuclide AR-41 CONCENTRATION (curies/cu m)3.84E-05 DATA ENTERED FOR STACK 2: CONCENTRATION Nuclide (curies/cu m)AR-41 3.84E-05 NOTES: Input parameters outside the "normal" range: None.RESULTS: You are emitting 4750.0 times the allowable amount given in the concentration table.* Failed at level 1.13 MARYLAND UNIVERSITY TRAINING REACTOR 2007-2008 ANNUAL OPERATING REPORT COMPLY: V1.5d. 7/11/08 10:19 7 2007-2008 MUTR Annual Report Ar-41 Release SCREENING LEVEL 2 DATA ENTERED: RELEASE RATES FOR STACK 1.Release Rate Nuclide (curies/YEAR)
