Maryland University Training Reactor Annual Operating Report, 2016 1 Introduction The University of Maryland Training Reactor (MUTR) is an open-pool type, TRIGA facility licensed for operation at 250 kW thermal power. The MUTR is primarily used for operator training and tours for groups internal and external to the campus. In addition, the facility provides neutron and gamma irradiations, and neutron activation analysis experiments for undergraduate lab classes and graduate research.

2 Reactor Usage Between January 1, 2016 to December 31, 2016, the MUTR operated for a total of 114 runs, which are categorized as follows:

Operator Training and Requalification 45 runs Tours, Labs, and Demonstrations 20 runs Calibration, Maintenance, and Surveillance 16 runs Irradiations or Activations 33 runs The total energy produced during this period was 25.48MWh with a corre-sponding burnup of 1.06 grams of U-235.

3 Surveillance Tests and Inspections All required surveillance tests and inspections were preformed at the intervals required by Technical Specification 4.0.

Maryland University Training Reactor Annual Operating Report, 2016 3.1 Maintenance Operations In addition to the above surveillance items, the following maintenance opera-tion~ were performed on the indicated dates:

3/8/16 Dri-rite replaced 4/22/16. Replaced primary resin 6/7/16 Dri-rite replaced 9/29/16 Dri-rite replaced 12/6/15 Replaced PuBe source string 12/8/16 Dri-rite replaced Additional minor maintenance was performed such as light bulb replacement and fine-tuning of equipment as necessary.

4 Changes to Facility There were no significant changes to the facility during this reporting period.

5 Environmental Surveys of Surrounding Areas Environmental surveys include tp.e routine environmental dosimeter measure-ments at the facility perimeter and the remainder of the locations on campus.

Measurements at all points were well within the historical norms.

6.2 Gaseous and Argon-41 The only release from the MUTR to the environment consists of Argon-41 pro-duced from the activation of natural Argon dissolved in pool water and natural Argon present in air within the interstitial spaces of beams and ports. Argon-41 escapes from the pool and spaces into the MUTR reactor building and then leaks to areas outside the building. The two main areas for assessment of public dose due to effluent release are outside the roll-up door on the north side of the reactor build ing and outside the lower reception room into the hallway 1398.

For this reporting period the reactor was operated for 326.25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />. EPA CAP88 was utilized to determine the dose outside the roll-up door to be l.91xl0- 1 mrem. The dose in the hallway 1398 from any effluent release is 6.04x10- 4 mrem.

Maryland University Training Reactor Annual Operating Report, 2016 7 Summary of Exposure Received by Facility Personnel and Visitors As part of the annual ALARA audit, facility management reviewed exposure records and found all badged personnel rE)ceived less than 10% of their annual dose limit. The pocket dosimeters recorded minimal exposure for all guests and service personnel.

• 8 Unscheduled Shutdown/Reportable Occurrences During this reporting period, there were 7 unscheduled shutdowns resulting in the reactor SCRAM.

• Run# 4476 Safety 2 High Voltage on January 8, 2016

• Run# 4478 loss of power to Regulating Rod on January 15, 2016

• Run# 4481 period scram on Feb. 10, 2016

• Run# 4506 external scram, undercount on exhaust ram on April 11, 2016

• Run# 4510 AC power glitch on April 14, 2016

• Run# 4560 external scram, undercount on exhaust ram on September 27, 2016

• Run# 4579 noise on wide range channel on November 4, 2016 There were no reportable occurrences during this reporting period.

9 Special Experiments There were no new special experiments performed during this reporting period.

10 Changes in Facility Staff During this period, 3 additional ROs, 1 instant SRO, and 1 SRO upgrade were

• added to the roster. Removed from the roster were 1 RO and 1 SRO .
