1.0 INTRODUCTION

This progress report covers activities at the Missouri University of Science and Technology Reactor (MSTR) Facility for the period April 1, 2012 to March 31, 2013.

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.

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 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.

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.

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 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 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 11, 2012. 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, 'Modern Physics'

7. Physics 207, 'Modern Physics II'

8. Physics 322, 'Advanced Physics'

9. Materials Science & Engineering 348, 'Energy Materials'

13 4.0 EDUCATIONAL UTILIZATION The reactor facility supported several Missouri S&T courses in the past year for a total of 10,249 student-hours. The number of Missouri S&T students utilizing the facility was 363. This usage is a direct result of an aggressive and continuing campus wide "outreach" program. The reactor facility provided financial support for six students with hourly wages. Additionally, students from several universities, colleges and high schools have used the facility.

Table 4-1 lists Missouri S&T classes taught at the facility along with associated reactor usage for this reporting period.

The Reactor Sharing Program, previously funded by the U.S. Department of Energy, was established for colleges, universities, and high schools that do not have a nuclear reactor. This past year, 1,387 students and instructors from 140 institutions participated in the program. Table 4-2 lists those schools and groups that were involved in this year's Reactor Sharing Program. The majority of participants were high school students. MSTR coordinates with the Missouri S&T Admissions Office to schedule high school students to see other items of interest at Missouri S&T after they have visited the reactor facility. The students visited the Missouri S&T Chapter of American Nuclear Society, the Computer Integrated Manufacturing Lab, the Foundry, Ceramics Engineering, Mineral Museum, Computer Center, Experimental Mine, Solar Car, Electron Microscope, and Stonehenge. The Reactor Sharing Program serves as a strong campus-wide recruiting tool by attracting high school students to the university and hopefully sparking some interest in nuclear engineering, science, and technology.

The reactor staff continues to educate the public about applications of nuclear science. Over 2,593 persons visited the facility during this reporting period. Tour groups are typically given a brief orientation and/or demonstration by a member of the reactor staff.

17 5.0. REACTOR HEALTH PHYSICS ACTIVITIES The health physics activities at the Missouri S&T Reactor facility consist primarily of radiation and contamination surveys, monitoring of personnel exposures, airborne activity, pool water activity, and waste disposal. All by-product material released from the reactor facility to authorized recipients is documented and surveyed. In addition, health physics activities include calibrations of portable and stationary radiation detection instruments, personnel training, special surveys, and monitoring of non-routine procedures.

5.1. Routine Surveys Monthly radiation surveys of the facility consist of direct gamma and neutron measurements.

There have been no unexpected exposure rates identified. Monthly surface contamination surveys consist of 40 swipes counted separately for alpha and beta/gamma activity. There has been no significant contamination outside of contained work areas found.

5.2. By-Product Material Release Surveys There were no shipments of by-product material released off-campus. There was no by-product release on campus.

5.3. Routine Monitorini Eighty six reactor facility personnel and students involved with the operations in the reactor facility are currently assigned, Thermoluminescent Dosimeters (TLDs). Three of the Reactor Staff have beta, gamma, and fast neutron dosimeters which are read twice monthly. There are also three other beta, gamma dosimeters used by the health physics personnel. There are also four area beta, gamma, and fast neutron dosimeters and two ring dosimeters, which are read twice monthly. There are three other area beta, gamma, neutron dosimeters that are read monthly. The remaining dosimeters detect beta, gamma,

18 and neutron radiation only and are read monthly. In addition, nine digital, direct-reading dosimeters and two chirper dosimeters are used for visitors and high radiation work. There have been no significant personnel exposures this reporting period. No visitor that was monitored with direct reading dosimeter received any reportable or significant exposure. There are nineteen area dosimeters assigned on campus for beta, gamma and neutron monitoring and one for beta, gamma, and fast neutron monitoring.

Airborne activity in the reactor bay is monitored by a fixed filter, particulate continuous air-monitor (CAM). Low levels of Argon-41 are routinely produced during operations. Release of gaseous Ar-41 activity through the building exhausts is determined by relating the operating times of the exhaust fans and reactor power during fan operation to previously measured air activity at maximum reactor power. During the period from April 2012 through March 2013, an estimated 18,027.1 [tCi of Ar-41 was released into the air.

Pool water activity is monitored monthly to ensure that no gross pool contamination or fuel cladding rupture has occurred. Gross counts and spectra of long-lived gamma activity are compared to previous monthly counts. During this period, sample concentrations averaged 9.16x 10-6 VCi/ml.

5.4. Environmental Monitoring There are three environmental dosimeters (TLDs) in place around the reactor building in order to monitor the environment for radiation exposure resulting from activities taking place at the reactor.

These badges are read quarterly. All exposures were within specified limits between April 2012 and March 2013.

5.5. Waste Disposal Solid waste, including used water filters, used resins, and contaminated paper/gloves is stored and/or transferred to the campus waste storage area for later shipment to a commercial burial site. The reactor pool water is analyzed for radioactive contamination and approval is required before the water is released into the sanitary sewer if necessary. During this period there was no waste transferred from the reactor facility to the DMSF on campus.

19 5.6. Instrument Calibrations Calibration of portable instruments and area monitors was completed according to schedule 6.0 PLANS The reactor staff will be involved in several major projects during the next reporting period; 1) modifying the control room console and rod drive motor systems, 2) conducting remote analysis of neutron irradiated samples, 3) development of a distant education program, 4) shipment of radioactive materials, and 5) continuation of the reactor operator training program.

6.1 Control Room Console and Rod Drive Motor Systems The control room rod height indicators and rod drive motors will be replace with a programmable logic controller and servo-motor drive systems. The chart recorders will be replaced with programmable logic controllers. The programmable logic controller system will replace the relay logic used to raise and lower control rods. Modification of the console will include replacing lights and switches.

6.2 Remote analysis of laboratory samples A third pneumatic transfer system connected to two heavily shielded cells and a glove box has been installed in the reactor core and made operational. The two shielded cells and glove box are located in the beam port room and is referred to as the Internet Accessible Hot Cell (IAHC) system. This year, 2013, the IAHC system has been made available for usage to analyze irradiated samples through a distant location technique. The controlling mechanism for the IAHC system is web based and designed to allow personnel not inside the reactor facility to move an irradiated sample from one shielded cell to another shielded cell containing one or more detectors. Additional detectors may be purchased to enhance the IAHC capabilities.

20 6.3 Distant Education A distant education system is being developed to conduct laboratory sessions with students of the Missouri S&T Nuclear Engineering program and students at other universities. Due to the size of the Missouri S&T Nuclear Engineering classes, the distant education system will allow students to participate in lab sessions as one group in larger classrooms than what is available in the MSTR building.

Equipment has been purchased to replace the existing rod drive motors, rod height indicators and recorders to output rod height and reactor data used in reactor theory labs. The reactor control room will be capable of outputting signals to the internet. Additional video equipment will be purchased to conduct video conferencing during the labs. The modification to control room equipment and installation of video equipment should be completed during the summer of 2013.

6.4 Shipment of Radioactive Materials Two members of the MSTR staff have been certified to ship radioactive materials. A secure room and shipping materials are still needed to be obtained prior to conducting the first shipment.

6.5 Reactor Operator Trainin2 The MSTR had one student operator upgrade their license to Senior Reactor Operator, one student obtained their Senior Reactor Operator License and one student obtained their Reactor Operator license.

The reactor staff is limiting operator training to only students with a very strong desire to obtain the license and assist reactor staff with reactor operations. At the end of the reporting period nine students were training for an operator's license.
