SUMMARY

During the 2018-2019 reporting period, the Missouri University of Science and Technology Reactor (MSTR) was in use for 2155 hours0.0249 days <br />0.599 hours <br />0.00356 weeks <br />8.199775e-4 months <br />. The majority of this time (~92%) 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.

The reactor facility supported several Missouri University of Science and Technology (S&T) courses and operator training over the year for a total of 1452 student-hours. The reactor was visited by 531 visitors during the past year. There were 305 of these visitors that participated in labs at the reactor.

The reactor produced 17450.27 kilowatt-hours of thermal energy using approximately 0.902 grams of uranium. A total of 162 samples were neutron irradiated in the reactor with the majority being analyzed in the reactor counting laboratory.

1 INTRODUCTION This progress report covers activities at the Missouri University of Science and Technology Reactor (MSTR) Facility for the period April 1, 2018 to March 31, 2019.

The reactor operates as a Missouri University of Science and Technology (S&T) 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 MSTR attained initial criticality on December 9, 1961 and 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 reactors design, as the MSTR is a light water, open pool reactor cooled by natural convective flow. The initial licensed power was 10 kW, which was up-rated to 200 kW in 1966. The MSTR utilizes Materials Testing Reactor (MTR) plate-type fuel and was converted from an original high-enriched uranium to low-enriched uranium fuel loading during the summer of 1992. The MSTR license was renewed for another 20 years in March of 2009.

The facility is equipped with several experimental facilities including a beam port, thermal column, three pneumatic transfer (rabbit) systems, and several manual sample irradiation containers and systems. The facility also contains a counting laboratory that has gamma spectroscopy capabilities. The gamma spectroscopy systems include germanium and sodium-iodide detectors, associated electronics, and state-of-the-art data acquisition and spectrum analysis equipment. Additionally, there is a liquid scintillation counter, thermoluminescent dosimeter reader, and x-ray imager for student and faculty use.

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.

No major upgrades or changes to the facility were performed over the past year.

However, new electronic dosimeters were procured and put into service to replace the existing units.

The updated MSTR Emergency Plan from 2017 remains in effect. Training under this plan was completed in January 2019. Efforts are underway between S&T Police, campus Environmental Health and Safety, and MSTR staff to conduct a large-scale injured person contamination drill.

On August 6-9, 2018, the Nuclear Regulatory Commission (NRC) conducted an inspection at the MSTR. The inspection covered the following areas: procedures; experiments; health physics; design changes; committees, audits and reviews; and transportation. The MSTR was notified during the inspection and by subsequent letter (dated August 30, 2018), that a Severity Level IV violation of NRC requirements had occurred. It was determined that contrary to MSTR Emergency Plan requirements, the NRC inspector found that, during calendar year 2017, no evacuation drills were held at the facility during either regular semester. In response (letter dated September 14, 2018), it was noted that evacuation drills have been performed in accordance with the MSTR Emergency Plan prior to and after the violation time frame, and that the drills have been incorporated into the MSTR Operator Training Program as of Spring 2018.

The MSTR was otherwise found to be compliant with current NRC requirements and MSTR Technical Specifications.

On November 26-29, 2018, the NRC conducted an inspection of the MSTR with regards to security. No significant security concerns or findings of non-compliance with NRC requirements were identified.

3 Independent auditors from the University of Missouri Research Reactor (MURR) audited the reactor facility on November 28, 2018. The audit cited an improvement in the written entries in to the Control Room Permanent Log Book, posting the current Health Physics surveys, and upgrading the dosimetry for visitors. It is noted that there is an agreement between MSTR and MURR to audit each other on an annual basis, which has been a very beneficial arrangement for both facilities.

In October, 2018, three students underwent NRC licensing examinations. The SRO license upgrade candidate and an operator trainee passed their respective exams. The remaining operator trainee failed a single exam section and is expected to retake the section in the following months.

The reactor staff have 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. The reactor is used mainly by the Nuclear Engineering Department for classes and research. The Reactor Lab II class reaches out to other departments on campus for collaboration projects. The reactor is working on resurrecting the reactor outreach program that was started in 1990 but has declined over past years.

Substantial efforts have continued to be invested in revising MSTR documentation, such as the SOPs, SAR, and other materials. Table 1-1 lists SOPs revised during the reporting period.

Note that these SOPs are provided in the appendices.

14 The Reactor Sharing Program was a U.S. Department of Energy (DOE) project intended to establish awareness and share education about the nuclear field beyond the campus. The MSTR established a corresponding program in 1990 and, while no longer DOE funded, is still active at the MSTR. As a related component, future nuclear engineering students are also brought to the facility for departmental tours.

During the reporting period, 531 students, instructors and public guests visited the MSTR facility for total of 536 hours0.0062 days <br />0.149 hours <br />8.862434e-4 weeks <br />2.03948e-4 months <br />. Of these 531 individuals, 305 participated in some kind of lab in the facility. Table 4-2 lists those schools and groups that were involved in this years program that are not part of S&T Nuclear Engineering Department. The majority of participants were high school students. The Reactor Sharing Program serves as a strong campus-wide recruiting tool by attracting high school students to the university and generating interest in nuclear engineering, science, and technology.

17 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. Releases of all by-product material to authorized, licensed recipients are surveyed and recorded. 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 exposure surveys of the facility consist of direct gamma and neutron measurements. No unusual exposure rates were identified. Monthly surface contamination surveys consist of 20 to 40 swipes counted separately for alpha and beta/gamma activity. No significant contamination outside of contained work areas were found.

5.2 By-Product Material Release Surveys There were no shipments of by-product material released off-campus. A total of 11.4 µCi of by-product materials were transferred on-campus to S&Ts materials license in accordance with SOP 603, Release of By-Product Materials on Campus, and the Missouri S&Ts Handbook of Radiological Operations.

5.3 Routine Monitoring Approximately 30 reactor facility personnel and students involved with the operations or regular experiments in the reactor facility are assigned Mirion Technologies Genesis Ultra Thermoluminescent Dosimeters (TLDs). The quantity of issued TLDs varies throughout the year due to class enrollment and personnel turnover, with reactor staff and operator trainees issued TLDs as soon as practical after their start. The full-time Reactor Staff have beta, gamma, and neutron whole-body TLDs along with individual TLD rings and five area dosimeters. This staff

18 dosimetry set is read twice monthly. There have been no significant personnel exposures during this reporting period.

There are three environmental TLDs outside the reactor building which are read quarterly. There are also five other beta, gamma, neutron dosimeters used by the health physics personnel and four other area beta, gamma neutron dosimeters that are read monthly. All remaining dosimeters are also read monthly. In addition, 10 digital, direct-reading dosimeters were procured in late 2018 to replace existing, aging digital dosimeters and are used for non-TLD-issued students and visitors. These digital dosimeters are also used for high radiation work along with audible dosimeters. No students or visitors received any reportable or significant exposure.

Airborne activity in the reactor bay is monitored by a fixed filter, particulate continuous air monitors (CAM). Low levels of Argon-41 are routinely produced during operations.

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. From April 2018 through March 2019 sample concentrations averaged 9.1x10-6 µCi/mL.

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, this period, an estimated 70,100 µCi of Ar-41 was released into the air.

5.4 Waste Disposal Solid waste, including 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. Water is analyzed for radioactive contamination and approval is required before the water is released. No waste was transported offsite during the reporting period.

19 5.5 Instrument Calibrations Portable survey instruments and meters are calibrated annually. Thirteen meters were calibrated on 9/21/2018, with the next calibration due in September 2019. Eight meters were calibrated on 3/14/2019, with the next calibration due in March 2020. Portable ion chambers were calibrated by an offsite vendor (Ludlum Instruments) on a rotating schedule of 6/18/2018, 8/6/2018, and 1/11/2019.

The previous digital dosimeters were calibrated 4/26/2018 and were replaced in October 2018. Half of the replacement dosimeters were calibrated (offsite) on 8/19/2018, with the remaining half calibrated on 3/5/2018 (also offsite).

The radiation area monitors were calibrated on 7/31/2018, with the next calibration due August 2019.

PLANS The reactor staff will continue to be involved in four major undertakings during the next reporting period: 1) updating the reactor documentation, specifically the SAR and SOPs, 2) replacing control room equipment, 3) expanding research to outside companies and other departments and 4) continuation of the reactor operator training program.

6.1 Reactor Documentation The SAR remains in need of updates. In the past 7 years the reactor has undergone several changes that have not been corrected or fully-documented in the SAR. The control room upgrades and chiller upgrades are among those projects.

The SOPs continue to be updated with the new university name in addition to minor changes and corrections. Any remaining non-digitalized checklists are also intended to be reformatted into fillable PDF files with electronic signatures.

6.2 Replacing Control Room Equipment A process of modernizing control room instrumentation started in 2017 with the Temperature and CAM recorder. Equipment to be replaced will be selected on a priority basis of what needs replaced and scope of project. Control room equipment replacement will have a thorough analysis of a 10 CFR 50.59 screening and evaluation/review process. The reactor staff will present the completed 10 CFR 50.59 review to the Radiation Safety Committee as required by MSTR Technical Specifications. The initial focus will be for converting the remaining paper recorders to paperless systems.

6.3 Reactor Operator Training The MSTR had two students obtain their license of Reactor Operator. The reactor staff is limiting operator training to approximately ten students with a very strong desire to obtain the license and assist reactor staff with reactor operations. The new training program has proven to be effective in keeping the students that want the license and work with reactor staff. At the end of the reporting period, six students were training for an operators license to take in the fall of 2019. The Reactor Manager, Reactor Director, and an additional faculty member are all also preparing for Reactor Operator and Senior Reactor Operator examinations in fall 2019.

SOP: 101 TITLE: GENERAL OPERATIONAL PROCEDURES Revised: March 26, 2019 Page 1 of 3 A. PURPOSE To provide written general operational procedures for routine operations.

B. PROCEDURE

1. Reactor operations must at all times meet the requirements of the Facility License R-79, Technical Specifications, and security in accordance with the provisions of 10 CFR 73.67(f).

2. At least two persons, as per Technical Specification 6.1.3 Staffing, shall be present in the Reactor Building when the reactor is operating.

3. The following additional staffing requirements shall be met:

a) A licensed operator who is responsible for reactor operation shall be present in the control room at all times when the reactor is operating.

b) Students and trainees may operate the reactor controls subject to the following conditions. In such cases the licensed operator maintains complete and total responsibility for all aspects of reactor operations.

i) Students and trainees may operate the reactor controls under the direct supervision of a licensed operator provided the excess reactivity is less than 0.7% delta k/k.

ii) Trainees may operate the reactor controls under the direct supervision of a Senior Reactor Operator when the excess reactivity is greater than 0.7% delta k/k and less than 1.5% delta k/k.

4. The reactor will be operated with the minimum amount of excess reactivity necessary to fulfill operational requirements as determined by the Reactor Director.

5. Read backs should be performed when verbally communicating without direct visual contact. This requirement is especially critical when handling fuel or radioactive samples. The NATO phonetic alphabet or jointly-agreed-upon system should be used for letters and numbers in the read back for brevity and clarity.

6. All reactor operational personnel are responsible for entering in the appropriate log book any work on or around the reactor or reactor components important enough to justify a record for future reference.

SOP: 101 TITLE: GENERAL OPERATIONAL PROCEDURES Revised: March 26, 2019 Page 2 of 3

7. All personnel are responsible for notifying the SRO on Duty of any work being done that could either directly or indirectly affect reactor operations.

8. Log books will be kept in the permanent log book cabinet, except the one currently in use, which may be kept on the console. If the books are removed from the control room, permission must be granted by the Reactor Manager. Any books removed shall be returned as soon as possible.

9. Only the SRO on Duty may authorize the use of bypass keys for control channel automatic functions. The use of any interlock bypass key requires a permanent log entry for insertion and removal. This log entry shall include date and time. This requirement does not apply when the reactor is shut down (e.g. performance of the Weekly Checklist procedure).

10. Any abnormal behavior or abnormal change in core reactivity associated with reactor startup or operation should be reported to the SRO on Duty immediately if there is any doubt about reactor safety, the reactor shall be immediately shut down by the licensed operator in the control room. The cause should then be determined Rev.

and corrective action taken.

11. The Standard Operating Procedure (SOPs) should be followed to the extent practicable, especially whenever the Pre-Startup Checklist is being completed, when the reactor is being started, or when the reactor power is being changed.

12. The SRO on Duty has the authority to instruct the reactor operator to disregard Rev.

certain SOPs provided that no safety requirements are violated (e.g., SOP 106 does not have to be performed following every shutdown while performing SOP 109).

13. All surveillance time intervals referred to in the SOPs are as defined in Section 1 of the Technical Specifications.
