Nuclear Engineering

The nuclear engineering graduate program offers the master of science, the doctor of engineering, and the doctor of philosophy degrees. B.S. in a field of engineering or suitable physical science is a prerequisite for admission into the nuclear engineering graduate program. The master’s degree program is designed to provide training and expertise in the design of nuclear energy systems, us of nuclear technology for medical as well as industrial applications. Both thesis and without thesis options are available for M.S. degree program with a minimum of 30 credit hours required for successful completion. Research areas of specialization include:

  • Reactor design and safety
  • Thermal hydraulics
  • Radiation effects
  • Radiation dosimetry, protection and health physics
  • Radiation transport and shielding
  • Space nuclear power
  • Materials for nuclear applications
  • Nuclear fuel cycle
  • Radioactive waste management
  • Radiation imaging and its applications in medicine and industry
  • Radiation measurements and spectroscopy

For the Ph.D. program, a research project with a written dissertation of high caliber demonstrating candidate’s capacity to conduct independent and original research, to critically analyze results and to infer sound conclusions is necessary. The dissertation must produce original research results acceptable for publication in a refereed journal. To facilitate high quality research, the nuclear engineering program has the following laboratory facilities:

Nuclear Reactor

The Missouri University of Science and Technology Nuclear Reactor (MSTR) is a Nuclear Regulatory Commission (NRC) licensed 200 kW pool-type reactor that is used to support the engineering and science activities on campus. Using the facility, the reactor staff provides hands-on laboratory, research and development and project opportunities. The reactor itself uses uranium fuel and is cooled by natural convection in a pool containing approximately 30,000 gallons of water.

The open pool design allows access to the reactor core where experiments and samples to be irradiated can be positioned. The facility is equipped with a pneumatics sample irradiation system, a neutron beam port that provides a collimated neutron beam, and a thermal column.

Internet-Accessible Hot Cell Facility

A dual-chambered internet-accessible heavily shielded facility with pneumatic access to the Missouri S&T 200 kW Research Nuclear Reactor (MSTR) allows authorized distance users to remotely manipulate and analyze neutron irradiated samples. The system consists of two shielded compartments, one for multiple sample storage, and the other dedicated exclusively for radiation measurements and spectroscopy. The second chamber has multiple detector ports, with graded shielding, and has the capability to support gamma spectroscopy using radiation detectors such as an HPGe detector. Both these chambers are connected through a rapid pneumatic system with access to the MSTR nuclear reactor core. The total transportation time between the core and the hot cell is less than 3.0 seconds.

Radiation Measurement and Spectroscopy Laboratory (RMSL)

The Radiation Measurement and Spectroscopy Laboratory is equipped for measurement of alpha, beta and gamma particles with the help of various detectors such as Geiger-Mueller counters, NaI (Tl) scintillation detectors, HPGe Semiconductor detectors, Ortec Ultra charged particle detectors, and Ortec partially depleted silicon surface barrier detectors. Detection systems including pre-amplifiers, amplifiers, single channel analyzers, counters, timers, multi-channel analyzers are also included in the laboratory. RMSL contains neutron and X-ray measurement modules using He-3 isotropic detectors and ion chambers respectively. All of the detectors in RMSL are compatible with state-of-the-art software and Lynx digital data analysis systems which allows remote web-based experimental capability. All of these things allows the RMSL tremendous potential for collaborative experiments and discoveries with local researchers and researchers around the world.

Nuclear Materials Laboratory

The facilities of the Materials Research Center, metallurgical engineering, and nuclear engineering programs are also available for nuclear materials-related research. These facilities include state of the art SEM/EDX, TEM, STEM, FIB/FESEM, and XRD.

Computer Laboratory

Students have the opportunity to use large computer codes commonly used in the nuclear industry for reactor core design, radiation transport, and thermal hydraulics analysis. The nuclear engineering program maintains an excellent laboratory with personal computers with access to a campus cluster of numerically intensive computing (NIC) systems.

Two-phase Flow and Thermal-Hydraulics Laboratory (TFTL)

The nuclear engineering TFTL is designed to perform both fundamental and advanced two-phase flow experiments simulating prototypic nuclear reactor conditions. The TFTL is equipped with state-of-the-art instrumentation such as a micro multi-sensor conductivity probe, a high-speed digital motion-corder, various flow measurement devices, and a data acquisition system and software. Topics of research studied in the TFTL include advanced two-phase flow modeling, two-phase flow characterization in various flow channel geometries, air-water two-phase bubble jet experiment, secondary flow analysis in liquid film flow, and development of two-phase flow instrumentation.

Advanced Radiography and Tomography Lab

The laboratory is designed to perform radiation imaging for medical or industrial purpose. Students have opportunities of running Monte Carlo simulation codes for radiation imaging systems and experimenting with digital x-ray radiography, x-ray computed tomography, neutron imaging, etc. The technologies developed in the lab can be applied to either medical imaging or non-destructive inspection of various materials or objects.

Neutron Generator Laboratory

The neutron generator laboratory has a D-D neutron generator that produces approximately 109 neutrons/sec. The neutron generator is available for both graduate and undergraduate research and education at Missouri S&T. Examples of research using the neutron generator are reactor kinetics research, the study of two-phase flow, research in nuclear forensics and radiochemistry, particle tracking in complex flows, and the photon-neutron tomography for mechanical testing of structural materials.
