Annual Report 2016-17



MISSION To serve our state, our nation and our global community by nurturing future nuclear engineering professionals and leaders who are: •

instilled with the highest standards of professional and ethical behavior

prepared to meet the complex challenges associated with sustainably expanding peaceful uses of nuclear energy

enhancing global nuclear security and avoiding the dangers of nuclear proliferation

VISION To develop and maintain a nationally and internationally recognized program that promotes a passion for understanding and applying the knowledge of nuclear science and engineering to support the nation’s alternative energy, national security and healthcare missions.

HISTORY The decision to enter the field of nuclear engineering was made in 1957, while Dr. John C. Calhoun was the dean of engineering. Our AGN-201 nuclear training reactor was purchased and installed in the mechanical engineering shops building, under the direction of Dr. Richard E. Wainerdi in 1957. In 1958, university leadership agreed that a Department of Nuclear Engineering should be created and that graduate programs in nuclear engineering be authorized. At that time, only two degree programs were administered: a Master of Science and a Ph.D. in nuclear engineering. The undergraduate program was established in 1966.

FICK IS FIRST NORTH AMERICAN AWARDED AKIYAMA MEDAL Lambert Fick, a doctoral student in the Department of Nuclear Engineering at Texas A&M University, received the Akiyama Medal for the best overall student paper as a part of the Student Paper Competition at the International Nuclear Engineering Conference (ICONE 24), held in Charlotte, North Carolina. Fick is the first North American student to receive the Akiyama Medal, a prestigious award presented by the Japan Society of Mechanical Engineers (JSME), in the conference’s 24-year history. Fick’s paper reflected his research relating to a new conceptual design of pebble bed nuclear reactors and was one of more than 120 papers submitted at the conference. Fick’s research is directed toward advanced nuclear reactors of complex flow within a pebble bed design, an aspect that has traditionally represented a challenge for computational research groups.

Fick is the first North American student to receive the Akiyama Medal in the conference’s 24-year history. “These flows are complex to simulate using computational tools,” Fick said. “We look at specific phenomena relating to turbulence, kinetic energy, the long-term temporal instabilities and the basic engineering parameters with higher order statistics, things of that nature that help us understand and apply the physics to design safer nuclear reactors.” Fick is an intern at Argonne National Laboratory in Chicago where he works with the lab’s nuclear engineering division. Dr. Yassin Hassan, head of the Department of Nuclear Engineering, serves as his faculty advisor. “My day is spent staring at computer screens doing simulations on the lab’s computing system, which is pretty cool because this is one of the fastest super computer cluster systems in the world,” Fick said. “We do very high degree simulations of these fluid flows on the order of thousands or tens of thousands of CPUs at a time to do these calculations. It’s pretty impressive stuff.” Fick and the computational team use geometries to simulate these flows and delve into the physics behind these reactor designs. Based on the understanding they generate from the simulations, they are able to extrapolate different developmental models to reduce computational costs to a design project. After having interned at Argonne for three years, Fick is hoping to pursue a position at the lab after receiving his Ph.D., and continuing his work related to advanced nuclear reactors. “We make some small incremental steps forward in our knowledge at a time, but the fact that we work on spherical or complex domains with a lot of curvature is a pretty novel thing,” Fick said. “I’m really interested in continuing this line of research since I feel that it really has some potential to impact the broad engineering community in a positive way.”



CERT RESEARCHERS ADVANCE PREDICTIVE SCIENCE FOR THERMAL RADIATION TRANSPORT The next generation of computers will operate at the exascale, which means that they will perform 1018 arithmetic (floating-point) operations per second, and numerical methods must be designed following certain computer science principles to be efficient on such computers. A multidisciplinary research team with the Center for Exascale Radiation Transport (CERT) at Texas A&M University is continuing to develop and validate new computational methods, applicable on exascale computers, for predicting measured quantities of interest related to thermal radiation “transport” in very hot matter. Thermal radiation “transport” is the emission, absorption, scattering and movement of thermal radiation within matter. Thermal radiation, also known as black body radiation, is emitted, absorbed and scattered by all matter. The amount and mean frequency of the radiation emitted rapidly increase with increasing temperature. The main application for CERT is high-energy laser experiments, which generate material temperatures on the order of 2 million degrees Fahrenheit. However, thermal radiation can be significant in many types of systems operating at much lower temperatures, including industrial boilers, turbine engines and nuclear reactors. The center’s research involves experiments, in addition to exascale computational methods development. Computer simulations are combined with experiments and statistical methods to estimate the accuracy with which measured quantities of interest can be predicted. The main idea is to recognize that there are many sources of uncertainty in both numerical simulations and experiments, and to statistically account for their cumulative effect on a predicted quantity of interest.


Neutron flux contours from an isotropic point burst of neutrons 9.5 nanoseconds after the burst started.

Relevant sources of uncertainty are not always obvious, and a major part of the center’s research is using a process known as hierarchical uncertainty quantification to help determine if all sources of uncertainty have been identified and properly characterized. “Our numerical simulations, which are performed on the fastest and largest computers available today, our experiments and our hierarchical uncertainty quantification methods help us to understand the extent to which of our new computational methods for radiation transport can be used to predict quantities of interest,” said Dr. Jim Morel, director and

principal investigator of CERT. “We are steadily advancing the state-of-the-art in this regard.” The center was created and is funded by the National Nuclear Security Administration under its Predictive Science Academic Alliance Program. CERT is led by Texas A&M, but it includes researchers at the University of Colorado, Boulder, and Simon Fraser University in Canada, as well as Texas A&M researchers from both the Departments of Nuclear Engineering and Computer Science and Engineering. The project was initially funded at $2 million a year for five years and will be extended for a sixth year.


RESEARCHER STUDIES CONNECTION OF TRACE ELEMENTS AS CANCER TREATMENT INDICATOR IN RADIATION DOSES Undergraduate student researcher Cailin O’Connell is helping to break new ground in radiation treatments by studying the connection of trace elements of zinc and their ability to be used as a treatment indicator for treating cancer to ensure accurate radiation dosages. Certain trace elements have the possibility to negate the effects of dangerous free radicals that can be created in the body during radiation and O’Connell’s project is breaking fundamental ground in helping to understand how these elements may open pathways to better treat patients.

O’Connell’s participation in this research project is supervised by Rihana Bokhari, a kinesiology doctoral student working under a research grant from NASA in relation to space biology research. Dr. Susan Bloomfield, professor in the Department of Health and Kinesiology at Texas A&M, is the principal investigator on the project.

reaction where they take an electron from a water molecule, and that water molecule goes on to take an electron from another water molecule and so on. DNA is surrounded by water, so you have this issue where you get problems like carcinogenesis where you have cancer that starts in the body because of irregularities in DNA.”

“When you’re exposed to radiation, free radicals are created in the body and zinc makes those free radicals, which are missing an electron, fulfilled by giving them an electron,” O’Connell said. “If this doesn’t happen, free radicals can go on to create a chain

O’Connell explained that through the team’s experimentation they hope to use this data, with zinc as an example, to create a diagnostic tool for determining how trace elements at specific quantities in the body can help or hurt patients so it can be applied to future research. The mechanisms of how the trace elements affect the absorption of free radicals within the tissues are not yet entirely clear, but O’Connell is excited to have contributed to what she views as fundamental research that may one day lead to something better. The research, which began as a part of Texas A&M’s Summer Research Grant Program, has contributed to her professional success by helping her secure an internship with Oak Ridge National Laboratory this past summer. “There is not a lot of research in this area so we are breaking new ground on this right now,” O’Connell said. “We’re trying to find this threshold where we are causing more good than harm with these treatments. It is very cool for me to think that someone could read my research in a journal one day and that could become a stepping off point for them. Just seeing all the cumulative buildup of this knowledge is cool and I’ve been excited to be a part of that.” This project is sponsored by NASA via the Space Biology Grant. The grant number is NNX13AL25G.



RESEARCHERS BUILD LARGEST TRANSPARENT FUEL TEST ASSEMBLY IN THE WORLD Researchers with the Department of Nuclear Engineering at Texas A&M University have provided new insights into the workings of an advanced sodium-cooled fast reactor fuel assembly, having used a specialized test facility to measure hydraulic parameters and validate computational tools used in reactor design and testing. The fast reactor assembly design used is significant, not only because of the complex inner knowledge it can provide about advanced reactors, but also because the Texas A&M experiment is using the largest transparent test fuel assembly of its kind to date. “TerraPower, AREVA and Argonne National Laboratories (ANL) have a strong interest in this new fuel design that will be potentially used in advanced fast reactors,” said Dr. Rodolfo Vaghetto, a research assistant professor with the department and project investigator. “This research is part of the work we do to ensure a new design goes from conceptual to something that you can actually build, operate safely and use to produce clean energy in an efficient way.” While the test assembly is unique in that it is the largest of its kind ever constructed, the researchers have also ensured the measurements taken are accurate through a novel technique, a transparent assembly. “Typical test assemblies are encapsulated in a stainless-steel container so you can’t see what’s going on,” Vaghetto said. “We made this assembly in acrylic so we can watch the processes and apply state-of-the-art techniques to measure full-field velocities at different locations inside the test bundle and pressure drops, something that has never been done before at this level of accuracy. That experimental data is then used by other members of this project, like TerraPower and ANL, to compare with their simulations of the assembly on the computational side and validate those tools.” The project was established in 2015 and is managed by nuclear utility company AREVA (subcontracted through the Department of Energy (DOE) in partnership with ANL, Texas A&M and TerraPower, the nuclear energy tech conglomerate led by Bill Gates. In the interest of taking the most accurate measurements possible, the researchers used a specialized fluid that has the same index of refraction as the acrylic of the assembly. They then inject the solution with a fluorescent dye and other seeding particles and expose it to a laser to obtain high-resolution measurements in their efforts to produce these high-quality measurements. The next step for the Texas A&M research team will be to continue experiments on the assembly for further developments, analyzing experimental data and collecting new data using the existing test assembly in partnership with other national and international collaborators. “There is a lot of interest in this type of geometry design for advanced fast reactors,” Vaghetto said. “This assembly seems to be the number-one fuel design right now, and these companies are looking forward in meeting their interests in performing these analyses. Because of the interest in this we’re hoping to get the chance to work on future projects with this assembly.”



NUCLEAR RESEARCHERS SEEK TO EXTEND NUCLEAR FUEL LIFE AND EFFICIENCY THROUGH IMPROVED FUEL PELLETS Researchers with the Fuel Cycles and Materials Laboratory within the Department of Nuclear Engineering at Texas A&M University are creating porous fuel pellets for use in reactors to extend fuel life, possibly reduce waste and increase the amount of energy the reactor can get out of the fuel. The project is a joint initiative with calibrators at the Georgia Institute of Technology and Idaho National Laboratory. Graduate student researcher Yesenia Salazar works under the group’s principal investigator Dr. Sean McDeavitt, associate professor of nuclear engineering and director of the Texas A&M Engineering Experiment Station’s Nuclear Science Center. Salazar’s job is to work with copper powder and produce the fuel pellets and test them under various pressures and scenarios to see how they perform in reactor-like conditions. Salazar works specifically with copper because its properties can be translated into digital code more easily, which is an important aspect for the computational side of this project involving modeling the behavior of the fuel pellets. “Our overall goal is that when we make this pellet, we take measurements for the porosity that it has,” Salazar said. “We’re trying to be able to have pores that are more or less homogeneous, where they are not just in one section of the pellet. If we can get more or less homogenous pores, we test them at these different pressure and temperature levels to see how they would perform inside a reactor setting.” The pores in these fuel pellets are meant to help counteract a phenomenon that occurs during nuclear power generation, where, after a short time, the pellets begin to swell because of the gases and fission products that are expelled during the energy generation process.

This expansion, if continued beyond a certain point, becomes dangerous not only in the process of producing energy, but also when the fuel source eventually has to be removed. Delaying the expansion of these pellets is where the pores come in. “We believe that if you have even just a little bit of porosity introduced into these pellets, those gases that are coming out and that swelling is happening will accumulate to make up for the space in those pores,” Salazar said. “It works very similar to the way a kitchen sponge works, soaking up all the water it can before its pores are full, at which point it expels the water. We want to delay the expulsion as long as we can.”

According to Salazar, the average lifespan of a nuclear fuel cycle can last anywhere from 16 to 36 months, and researchers are hoping that the pellets may extend the process at least an additional week or more. This translates into significant energy production per ton of fuel. “The potential of nuclear power is truly humongous,” Salazar said. “This research is really great so far and can have even greater results years from now, but I feel like those results can only be empowered if the general public’s view is more accepting of the benefits of nuclear energy.”




Researchers within the department’s Ion Beam Laboratory group are speeding up the clock on metallic alloys and steels, using ions as surrogates for neutron radiation to see in a short amount of time how stable these metals are after they endure conditions from decades of use inside a nuclear reactor. “We’re essentially taking these alloys and irradiating with ions to achieve damage seen in reactor-like conditions,” said Jonathan Gigax, a graduate assistant researcher who works under the lab’s principal investigator, associate professor Dr. Lin Shao. According to Gigax, this research helps qualify and screen a large number of candidate alloys, whose test results provide an understanding of the unique properties that make certain alloys radiation resistant. This allows new alloys to be developed for use in reactor construction and help achieve efficient use of the reactor’s fuel. To achieve optimum efficiency the reactor has to operate at a high burnup, which places stress on the metals and alloys within the reactor. To achieve highly


efficient fuel burnups, alloys that can resist microstructural changes from damage produced neutron radiation, also known as creep and swelling, are necessary to ensure a long working life for the reactor. “A good example of creep phenomena would be a filament in an incandescent light bulb,” Gigax said. “The filament remains at a very high temperature for a long period of time and slowly deforms until it breaks. The same thing can happen with steels at high temperatures or under large stresses, so the idea was that we needed to develop an alloy that does not exhibit creep to a large extent.”

said. “We can look at what makes one alloy better than the others and then guide the further development of that alloy based on its positive qualities, or once you identify a good alloy you can dedicate resources to having that put inside a nuclear reactor to test it in the exact conditions.” Through the usage of the ion accelerators, the time and cost commitment for reactor testing is dramatically reduced, allowing the research to advance efficiently. In addition to ensuring a longer working life and durability of these reactor materials, these applications also have benefits for the consumer.

The steels used in the reactor, as a result of creep and swelling, undergo deformation and change the operating behavior of the reactor. Single crystal metals are resistant to creep but are expensive to make and typically exhibit more void swelling than polycrystalline counterparts. Very small grains offer better swelling resistance but make the steel susceptible to creep.

“We are contributing to the energy needs of the nation,” Gigax said. “By contributing to the development of materials that can take the added radiation stress of operating at higher, more efficient fuel burnups, which translates to more energy output per source of fuel, we’re helping make cheaper and more accessible energy for the average consumer.”

“Once you get all these research results, there are two things we can do,” Gigax

The research is funded by the U.S. Department of Energy.


TEXAS A&M NUCLEAR RESEARCH TEAM SOLVES GENERIC SAFETY ISSUE 191 IN COLLABORATION WITH SOUTH TEXAS PROJECT PLANT A research team with the Department of Nuclear Engineering at Texas A&M University, in collaboration with the South Texas Project Nuclear Operating Company (STPNOC), has solved the problem of a loss of coolant accident in a nuclear reactor, which can cause debris to be generated and potentially impact the performance of the safety system. The team provided a solution to the U.S. Nuclear Regulatory Commission (NRC) for Generic Safety Issue 191 (GSI191). GSI-191 regards the generation of debris during a loss of coolant accident and the potential consequences to the emergency system performance. The methodology that the team has developed will allow this safety issue to be addressed in light water reactors (LWR) across the country and is the first to be approved by the NRC.

similarities and variable differences between plants. Texas A&M’s collaboration with STPNOC on this project began in 2010, where through seven years of partnership and continuous interactions between five divisions and 14 branches of the NRC staff, the methodology was developed. In developing this methodology, two risk-informed approaches were used, the full risk-informed approach and the risk over deterministic method. The department’s main attribution to this project is through the thermal hydraulics calculations and experimental studies performed. Texas A&M is the first to perform these types of complex analyses, with over 100

different scenarios simulated. Through the approval process of the licensing amendment, more than 50 public meetings and 400 requests of additional information were completed, in addition to 13 project audits, before the license amendment was issued in July 2017. “We’ve made great progress in the nuclear power plant safety methodology and we look forward to other nuclear plants adopting the STPNOC methodology to resolve the GSI-191 issue,” said Rodolfo Vaghetto, co-principal investigator with the project and a research assistant professor at Texas A&M.

The loss of coolant accident is a design basis accident, meaning that when a reactor design is licensed, it has to be designed to handle these type of accidents safely under any circumstance. GSI-191 is a safety issue that results during a loss of coolant accident where debris can be generated and potentially impact the performance of the safety system pumping water through the primary system in an attempt to cool the reactor to safe levels. The debris blocking sump strainers and other flow paths can cause insufficient amounts of water to be recycled through the system, which means the reactor isn’t being cooled efficiently or safely. To solve this problem, STPNOC partnered with Texas A&M to develop a widely applicable methodology, approved by the NRC, that can be applied to theoretically any operating LWR plant across the country. The methodology provides guidance on evaluating the safety level of the plant against the GSI-191, accounting for



NUCLEAR POWER PLANT SIMULATOR LAB PROVIDES HANDS ON EDUCATIONAL EXPERIENCE FOR STUDENTS Have you ever had interest in operating a nuclear power plant? The Department of Nuclear Engineering at Texas A&M University is providing students with industry experience, enhancing their education with the Nuclear Power Plant Simulator Laboratory. The laboratory simulator provides hands-on training to students, teaching them how to handle operating a real reactor under a variety of situations and scenarios. The device also supplements classroom coursework, allowing the students to put concepts they have learned in the classroom to practice in a safe and secure environment. The laboratory that houses the simulator has two types of power plant simulators, a set of broad scope simulators, including IAEA simulators, and a PCTRAN simulator and a fullscope GSE GPWR simulator. “The simulator laboratory provides a unique learning environment,” said Dr. Pavel Tsvetkov, associate professor of nuclear engineering and faculty graduate advisor. “It gives students the platform to develop a thorough


understanding how plant systems are working together from power systems, to energy grid infrastructures, accounting for their electricity generation, as well as cyber physical security implications.” The simulator offers a variety of situation specific scenarios, including academic demonstrations of safe operation usage, allowing students to step into the shoes of a nuclear reactor plant operator inside of a live control room. In addition to the simulator’s educational uses for students, it also supports research efforts in areas related to the dynamics and control of light water reactor plants, helping better understand interactions between the reactor and energy grid that occur during operation. The simulator also serves a function by providing insight regarding the operation, safety evaluation and human factors that impact the plant’s usage and efficiency. “We are utilizing the simulators in our joint research efforts and engaging both graduate and undergraduate students,”

Tsvetkov said. “We’re envisioning that the simulator environment will serve as a computational framework for research and development in various existing and emerging areas of interest involving current and future nuclear reactors and plant systems. The opportunities are really limitless. We have interests in design, operation, safety, grid interfaces, security, humanmachine interfaces and many others.” While the department currently has two nuclear reactors for education and research, the simulator serves as yet another avenue for these initiatives. “In the spirit of working to developing the next cohort of the nuclear workforce the simulator allows us to expose our students to the plant equipment and its features,” Tsvetkov said. “This offers a real nuclear plant environment that will only serve to benefit our students and our research. Our students get once-in-a-lifetime opportunity to run a nuclear power plant as they would have if they would be at the plant.”

ENGINEERING EDUCATION COLLEGE OF ENGINEERING’S 25 BY 25 INITIATIVE In 2013, Texas A&M University’s College of Engineering embarked on a transformational program called 25 by 25. As a response to the national call for more engineering graduates, and with our engineering advisory board’s strong support of the program, 25 by 25 is designed to increase access for qualified students to pursue engineering education at Texas A&M and increase our total enrollment to 25,000 students by 2025. The 25 by 25 initiative is not just about increasing numbers; we are focusing on enhancing the quality of our students’ educational experience and the excellence of Texas A&M’s engineering program. The 25 by 25 initiative is positively recognized by our academic peers and overwhelmingly supported by our former students and industry. In fact, we have raised more than $250 million in gifts in support of 25 by 25.

Q. How does the College of Engineering plan to grow? A. The majority of future student growth from 25 by 25 will occur through the retention of our incoming students, growth at our branch campus locations and statewide engineering academies, and through the expansion of our online graduate programs. Q. How is the college enhancing education? A. We are improving the educational experience for our students through active learning, smaller class sizes, unique learning experiences and improved first-year engineering classes. We are expanding our learning facilities, including the 525,000 sq. ft. Zachry Engineering Education Complex. We are also growing our faculty. Our college has 578 top faculty scholars and professors of practice. Q. Are you lowering your admission standards? A. No. In fact, the admission standards to the College of Engineering have been enhanced. For students admitted for Fall 2017, the average SAT math score is 709, which is significantly higher than the average math score of 683 in fall 2016. And once students are admitted into Texas A&M, they now undergo a holistic review process to be admitted into the college.

For the latest information about the initiative, please see To get involved and support our program, contact Andy Acker at or 979-458-4493.

GIVE A GIFT, EMPOWER A FUTURE Education is a gift that keeps giving throughout one’s life, long after college is over. The Department of Nuclear Engineering at Texas A&M University has graduated more nuclear engineers since the early 1960s than any other school in the country. More important than the number of graduates is the quality of those graduates. We go above and beyond to recognize the potential in students, and provide them with an education to be proud of. We continuously strive to inspire our students, faculty and staff to be the best they can be. We stand by our vision: to develop and maintain a nationally and internationally recognized program that promotes a passion for understanding and to apply the knowledge of nuclear science and engineering to support the nation’s alternative energy, national security and healthcare missions. Our program is constantly evolving and is focused on developing and strengthening every facet required to raise student achievement in and out of college. We aspire to be better and to improve each year. For that we require your support. The search for the best students is tougher than ever. As we continue our tradition of producing high-quality nuclear engineers the industry needs, a key factor is the ability to attract the most academically capable students. Some of the best and brightest high school students cannot afford today’s tuition and scholarships open a world of possibilities to them. For others, a scholarship frees them from student jobs, giving them more time to follow their intellectual curiosity or participate in Texas A&M’s character-building, student-led organizations. There are many opportunities available for empowering the students of the department. Scholarships drive the spirit and guide the minds of generations of Aggies, so they can affect the world in productive and inventive ways. When you fund a scholarship, you’re making a profound difference for individual students and the lives those students touch as graduates of Texas A&M. Contact Megan Pulliam, assistant director of development, to make a difference in a student’s life.
