Dear Dr. Tedesco:
This annual report is submitted in accordance with the requirements set forth in our Technical Specifications for the Maryland University Training Reactor. This report covers the time period from June 30, 1984 through June 30, 1985.
A. Summary of Operation Experience The Maryland University Training Reactor facility license was rene* red for another twenty years.
No major difficulties were encountered with the reactor during this reporting period.
We continued to provide reactor service to the' Nuclear Engineering courses; primarily, ENNU 320 - Nuclear Engineering Technology. This service utilized the reactor for six (6) one half days per week including Saturday. Our activation analysis ser/ ice has increased to the level where one-third of all start-ups were in this area.
The general reactor operation can conveniently be broken down into the following categories:

THEUNIVERSITYOF MARYU\ND COLLEGE PARK CAMPUS Depcriment of Chemical and Nuclear Engineenng Page - 2 Ltr. - Dr. R.L. Tedesco July 24, 1985 (a) Activation Analysis (33%)
(b) Operator Training and Nuclear Technology Classes (38%)
(c) Calibration and maintenance (136). A significant portion of this was part of the operator training program (d) Tours and Demonstration (16%)
The DOE " Reactor Sharing Program" was renewed at the same level of effort for this reporting period. This enabled us to use about five (5) students on a part time basis to support reactor operations.
During this period we made the Reactor Operation Train-ing Program available to undergraduates. Three (3) under-graduates passed the Senior Reactor Operators examination and were granted their license at a ceremony conducted by the Nuclear Regulatory Commission on June 24, 1985.
No major changes were made to the reactor during this reporting period.
B. Reactor Operations During the period 30 June 1984 through 30 June 1985 the reactor was operated 143 times and produced a total of 12 megawatt-hours of energy.
C. Equipment Surveillance and Tests control rod calibration and drop tite were performed.

()__J THEUNIVERSITYOF MARYLAND COLLEGE PARK CAMPUS Department of Chamical and Nuclear Engineering Page - 3 Ltr. - Dr. R. L. Tedesco July 24, 1985 No significant changes from previous measurements were observed.
Control rod drop time showed little, if any, change during this period. The measured values were of the order of 0.6 to 0.7 seconds, well within Technical Specifications.
The control rods were removed, measured for any dimensional changes and physical deteriation. No changes were found.
Pool water was sampled on a monthly basis and gamma ray analysis made using a GeLi detector and a multi channel analyzer. _ No element concentration associated with fission products (above background) was found.
All area and portable survey meters were calibrated on a timely basis in accordance with Technical Specifications.
No significant calibration change was required.
D. Emergency Shut-Down AND Scrams No emergency shut-down or scram occurred during this operating period.
E. Maintenance Items 7/19/85 Problem: Failure of external radiation monitors.
Solution: Investigation revealed that the transformer in the power supply had shorted out. The transformer was rewired and the system restored to normal opetation.
8/8/85 A radiation monitor was installed in the glove box containing the rabbit return pneumatic system. A radiation-level meter was installed in the reactor console to provide information to the operator concerning dose rates at the return.

THEUNVERSITYOF MARYLAND COLLEGE PARK CAMPUS Department of Chemicot and Nuclear Eroneering Page - 4 Ltr. - Dr. R.L. Tedesco July 24, 1985 8/12/85 The external radiation monitors were cleaned and serviced, the electrical power plugs were replaced. The monitors were calibrated and returned to service.
9/29/84 A new neutron source' motor drive was installed.
12/5/84 Safety channel one and safety channel two power meters as well as the compensated ion chamber readout were tested and calibrated.
3/7/85 Repaired on-off electrical switch on high voltage circuit.
5/85 The Pneumatic System failed to insert a capsule in'.o core. The activating system was dismantled and the sliding "on-off" valve was found to have a defective "O" ring. A new valve was installed and the system performed correctly.
6/11/85 The in-line temperature gauges for the primary water system were removed and recalibrated.
F. A summary of the nature and amount of radioactive offluents released or discharged to the environment and or radioactive waste shipped off site for disposal.
During this reporting period no waste water containing any measurable radioisotope was discharged to th'e sewage system. In addition, monthly air samples were taken in the reactor area. The samples contained no activity greater than background.

THEUNIVERSITYOF MARYLAND COLLEGE PARK CAMPUS Department of Chertucal and Nuclear Engineenno Page - 5 Ltr. - Dr. R.L. Tedesco July 23, 1985 G. Radiation Exposures In the period June 30, 1984 through June 30, 1985, approximately 437 people visited the reactor facility.
This is in addition to the badged personnel taking reactor courses and operating personnel. In all cases the radiation received was negligible. Floor and area wipes have been routinely carried out with the results that any contaimination was far below the maximum permissible level.
H. Changes to the Facility on Procedures, Tests, and Experiments.
All procedures have been reviewed and where necessary have been modified, revised or deleted in order to conform with the new Technical Specifications and the ALARA concept.
