1.

Introduction The Texas A&M University (TAMU) Nuclear Science Center (NSC) is a multi-disciplinary research and education center supporting basic and applied research in nuclear related fields of science and technology as well as providing educational opportunities for students in these fields as a service to the Texas A&M University System and the state of Texas. The NSC also provides services to commercial ventures requiring radiation or isotope production services.

The NSC reactor is a 1 MW TRIGA research reactor in a large (108,000-gal.) pooi. The size of the NSC reactor pooi provides great flexibility in the experiments that may be conducted near the reactor. The NSC reactor facility includes two neutron beam ports, a neutronlgamma irradiation cell, a film neutron radiography system, hot cells with manipulator arms, and other supporting facilities. Moreover, NSC has Cs-137 calibrator for use in instrument calibration.

Laboratory facilities include counting laboratories with gas flow proportional detectors and High Purity Germanium detectors, a two-station pneumatics sample transfer system, and a fast neutron irradiation system.

The NSC reactor design allows for easy loading/unloading of various types of samples. The NSC actively produces a variety of radioisotopes for academic and industry users. The NSC provides nationally recognized neutron activation analysis (NAA) services to many research and academic institutions in the United States. The Nuclear Engineering Department on campus is a major user of the NSC reactor. The NSC is also one of the major attractions on campus. Last year, the NSC hosted approximately 1700 local and international visitors including: elementary, middle school, high school and college students as well as faculty members, national laboratory scientists and industrial clients. Through these tours, the NSC taught people with widely varying backgrounds about nuclear science.

With the DOE reactor upgrade funding from 2014, the NSC has acquired new continuous air monitors, a second sample handling cell, a replacement/upgrade to our heat exchanger; and we are negotiating a replacement pool demineralizer system. These purchases will enhance and help extend the safe operation of the NSC for many years to come.

The NSC has submitted the license amendment request as well as the revised Tech Specs, SAR, and other supporting documents for the renewal process with Nuclear Regulatory Commission (NRC). They are under review and are still pending with the NRC.

This annual report has been prepared to satisfy the reporting requirements of Technical Specification 6.6.1 of the facility operating license R-83 and of the Department of Energy University Reactor Fuel Assistance Program subcontract No. C87-101594 (DE-AC07-76ER02426).

The Director of the NSC is responsible to the Deputy Director of the TEES for the administration and the proper and safe operation of the facility. The NSC Radiation Safety Office is responsible to the Director of the NSC for matters relating to safety and for maintaining a proper radiation safety program. In addition to the internal structure, the Reactor Safety Board (RSB) advises the Deputy Director of the TEES and the Director of the NSC on issues or policy pertaining to reactor safety. The Texas A&M University Environmental Health and Safety Department (EHSD) provides assistance when required for emergencies and for special operations as agreed. The Texas A&M University Police Department provides security support on a daily basis and is a key support group in the event of a security incident. The College Station Fire Department and Scott & White Medical Center provide offsite emergency support when required as per agreement.

2.

Reactor Utilization for 2014 The Nuclear Science Center (NSC) reactor has been in operation since 1961. The reactor is a 1 MW MTR-converted TRIGA reactor. Core IX is the current core configuration and has been in use since September 2006. The NSC reactor is pulse operational and was pulsed up to $1.75 for nuclear engineering laboratories, staff training, and public tours.

The NSC reactor operated for 2011.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> in 2014 with a total integrated power of 82.8 MW-days. There were 479 "Requests for Irradiation" processed at the NSC during the reporting period. The NSC provided services to TAMU departments, other universities, research centers, and secondary schools in and outside the state of Texas. The cumulative total energy output since initial criticality of the LEU fuel is 621.3 MW-days.

Texas A&M University System Nuclear Science Center Ana eot21 Annual Report 2014 2.1 TAMU Academic Support Program Texas A&M University provides funding for the reactor for such academic activities as nuclear engineering laboratories, neutron activation analysis demonstrations and laboratories, graduate student thesis and dissertation research, and undergraduate research projects. The program has been very successful and is crucial for many graduate students who use the NSC reactor for research and have not received research grants. The wide range of academic users from the university reflects in the NSC's reputation as a multi-disciplinary institution.

2.2 Commercial Activity and External Research The NSC provides services to a variety of users that provide their own funding. The majority of conmmercial activities focus on production of radioactive tracers for the petroleum and chemical industries.

Outside research grants fund a significant amount of the NSC's research. The NSC is involved with neutron activation analysis and radioassays for a wide variety of samples for outside customers. The NSC has many years of experience producing radioisotopes and has developed several customer-specific methods for radioactive sample production and handling.

The production of radioisotopes generally involves handling radioactive material with high activities. The NSC staff takes precautions to minimize the exposures during the transfer of radioactive materials to shipping shields.

Facility and Procedure Changes 3.1 Facility Modifications 3.1 Continuous air monitors 3.2 Sample handling cell 3.3 Primary coolant heat exchanger 3.2 Experiment Authorization and Modification Authorization There were no new Experiment Authorizations (BA) and one Modification Authorization (MA) covered in 2014. Modification Authorization 61 was approved for the Primary Heat Exchanger replacement.

4.

Reactor Maintenance and Surveillance 4.1 Scheduled Maintenance NSC personnel performed regular maintenance on the Fuel Element Temperature Channel, Area Radiation Monitors and the Linear, Log, and Safety Power Channels as required by the Technical Specifications; They also performed all, surveillance required by the reactor license. Control rod worth and scram time measurements performed in June 2014 gave the following results. The total rod worth was $1 5.928. The most reactive control rod was Shim Safety #4 with a worth of $4.19. The shutdown margin was $6.024 and core excess was $4.967.

Texas A&M University System Nuclear. Science Center Ana eot21 Annual Report 2014 5.1 Radioactive Shipments The Health Physics monitoring and technical support that was provided in 2014 assured minimal exposure during sample handling, shipment of radioactive material, and normal reactor operation. The radiation exposures were maintained ALARA. During 2014, about 328 radioactive samples were handled and released to various facilities including Texas A&M University campus. A total of 525 curies were handled in 2014.

5.2 Personnel Monitoring Personnel Monitoring was provided on a monthly basis to approximately 64 personnel. All measured doses to personnel were below the limits set forth in 10 CFR 20. Three individuals received whole body dose greater than 10% of the annual limit in 10 CFR 20. Their deep dose equivalent (DDE) recorded were 0.81iR, 0.50R, and 0.75R for the year. Airborne monitoring during sample handling continued to show no significant airborne activity, therefore, total effective dose equivalent will equal deep dose equivalent for 2014. A total of 5.9 manrem was recorded for the year 2014. When total manrem/curie was determined for 2014, the dose per curie equaled 0.011 (manrem/Ci).

During 2014, 1779 visitors toured the Nuclear Science Center. Minimal exposures were measured with pocket ion chambers worn by these visitors and the pocket ion chamber readings of their respective tour guides.

NSC employees who were likely to exceed 10% of their total annual dose wore whole body badges (Luxel dosimeter) and extremity badges (TLD dosimeters) that were provided by Landauer, a NVLAP accredited supplier. Landauer also provides the reports of the doses received. Employees who potentially handle, more radioactive materials on a regular basis were provided two extremity badges and were changed out on a monthly basis.

5.3 Facility Monitoring Surveys of the Nuclear Science Center facilities were performed to assess radiological hazards to NSC workers. Radiation levels and sources of radioactive contamination were routinely monitored. All areas accessible to the general public at the NSC were surveyed for radiation and contamination levels with an ion chamber and evaluation of smear samples. Areas where contamination is expected are access/egress controlled and are evaluated on shorter intervals as needed. Building monitors and area monitors are located strategically throughout the reactor facility, providing dose equivalent (mrem) on a monthly basis. Table 5-3 summarizes the annual accumulated dose equivalent (mrem) recorded on the area monitors for the year 2014.

Environmental Monitoring In conjunction with representatives from the Texas Department of State Health Services (TDSHS) Radiation Control, a quarterly environmental survey is conducted to insure compliance with federal regulations. This program consists of TLD monitors located at various locations on the NSC site and two background monitors; one located at 3.84 miles NW of facility and the other at 0.25 miles SE of facility.

6.1 Environmental Samples Since the implementation of discharging liquid waste to the sewer, TDSHS no longer requires the collection of a quarterly sediment sample. A letter from TDSHS to this effect is on file.

16

Texas A&M University System Nuclear Science Center Ana eot21 Annual Report 2014 6.2 Site Boundary Dose Rate The environmental survey program measures the integrated radiation exposures at the exclusion area boundaries. These measurements are made for periods of approximately 92 days using TLDs. Monthly measurements of direct gamma exposure rate in *tR/h are also made at each of the TLD locations. The dosimeters were provided and processed by Texas Department of State Health Services, Environmental Monitoring, Division of Regulatory Services, Austin, Texas.

The total TLD dose is multiplied by the occupancy factor (1/16) to determine the deep dose. To determine the dose to the public outside the site area from air effluents, the EPA approved code COMPLY was used. The annual dose calculated using COMPLY was 0.1 nmrem/yr. This is added to the deep dose to determine the total dose to the general public and the maximum dose.
