SUMMARY

During the 2013-2014 reporting period, the Missouri University of Science and

- Technology Reactor (MSTR) was in use for 493.07 hours8.101852e-5 days 0.00194 hours 1.157407e-5 weeks 2.6635e-6 months . The major part of this time, about 90%, was used for class instruction, research, and training purposes.

The MSTR operated safely and efficiently over the past year. No significant safety-related incidents or personnel exposures occurred.

0 The reactor facility supported several Missouri University of Science and Technology

(Missouri S&T) courses over the year for 24,768 student-hours. About 2,446 visitors visited the

reactor during the past year. There were 1,660 participants, mostly high school students, in the

U.S. Department of Energy Reactor Sharing Program.

0

The reactor produced 35,496.0 kW/hrs kilowatt-hours of thermal energy using approximately 1.5 grams of uranium. A total of 351 samples were neutron irradiated in the reactor with the majority being analyzed in the reactor counting laboratory.

1.0 INTRODUCTION

9 This progress report covers activities at the Missouri University of Science and Technology

Reactor (MSTR) Facility for the period April 1, 2013 to March 31, 2014.

The reactor operates as a University facility. It is available to the faculty and students from various departments of the University for their educational and research programs. Several other college

and pre-college institutions also make use of the facility. The reactor is also available for the training of personnel from commercial concerns with legitimate interest in our facility use.

0 1.1 Background Information

The Missouri University of Science and Technology Reactor (MSTR) (formally University of

Missouri-Rolla Reactor) attained initial criticality on December 9, 1961. The MSTR was the first operating nuclear reactor in the State of Missouri. The Bulk Shielding Reactor at Oak Ridge National Laboratory is the basis for the reactor's design. The reactor is a light water, open pool reactor cooled by

natural convective flow. The fuel is MTR plate-type fuel. The initial licensed power was 10 kW. The 9 licensed power was up-graded to 200 kW in 1966. During the summer of 1992, the reactor fuel was converted from highly enriched uranium fuel to low-enriched uranium fuel.

0

The facility is equipped with several experimental facilities including a beam port, thermal column, three pneumatic rabbit systems, and several manual sample irradiation containers and systems.

The facility also contains a counting laboratory that has both gamma and alpha spectroscopy capabilities.

9 The gamma spectroscopy system includes germanium and sodium-iodide detectors, associated electronics, state-of-the-art data acquisition, and spectrum analysis software. The alpha spectroscopy S

system consists of a surface barrier detector and data acquisition equipment. Additionally, there is a thermo luminance dosimeter reader, digital neutron radiography imager, and x-ray imager for student and

faculty usage.

~The T MSTR also uses a biometric device to enhance its traditional security system.

2 1.2 General Facility Status The MSTR operated safely and efficiently over the past year. No significant safety-related incidents or personnel exposures occurred.

An independent auditor from the University of Columbia audited the reactor facility on December 4, 2013. There were no significant areas of concern. There is an agreement between the MSTR and the University of Missouri-Columbia to audit each other. This has been a very beneficial arrangement for both facilities involved.

The reactor staff has continued to review the operation of the reactor facility in an effort to improve the safety and efficiency of its operation and to provide conditions conducive to its utilization by students and faculty. An "outreach" program, implemented over the past few years, has been continued in order to let both students and faculty in a number of departments across campus know that the reactor could be used to enhance course work and research. As a result, additional classes have been using the reactor facility to augment their programs, including:

1. Chemistry 2, 'General Chemisty Laboratory' 2 Civil Engineering 310, 'Senior Design Class'

3. Engineering Management 386, 'Safety Engineering Management'

4. Mechanical Engineering 229, 'Energy Conversion'

5. Life Sciences 352, 'Biological Effects of Radiation' 6 Physics 107, 'Modem Physics'

8. Physics 322, 'Advanced Physics'

3 9 SOPs were revised, over the past year in order to improve and keep current the operations and

efficiency of the MSTR. The following is a list of SOPs revised during the reporting period:
