Why is this research important?

More

In recent years, nuclear energy has emerged as a viable source of clean, carbon-free energy capable of meeting the world’s increasing demand for electricity. However, several technical issues still need to be resolved including waste, supplies of fuel and nonproliferation.

CAES researchers are helping to solve some of the most critical technical issues related to nuclear energy, including identifying solutions to safely handle, store, and dispose of nuclear waste, developing new materials that can be used in the next generation of reactors, securing and safeguarding materials and facilities, exploring novel small and hybrid nuclear energy systems, and extending the life of the nation’s current fleet of light water reactors.

The nuclear science and engineering research conducted at CAES complements the work already underway at each of its partner institutions – Boise State University, Idaho National Laboratory, Idaho State University, University of Idaho, and University of Wyoming.

CAES nuclear scientists and engineers are:

  • Developing a process called electrochemical treatment to separate spent nuclear fuel into uranium metal and ceramic and metal wastes.
  • Identifying methods to reduce radioactivity in nuclear waste, including removing C-14 from the graphite used in a variety of nuclear reactors.
  • Educating faculty, students, and practitioners from around the world on best practices to secure radioactive and nuclear materials and facilities.
  • Exploring new ways to use accelerators to produce radionuclides that help meet the nation’s growing needs in research and medicine.
  • Performing separate effects testing to investigate the relationship between radiation, high pressure, and high temperature on nuclear materials.

Heavy Vehicle Simulator

Researchers in CAES are using the Heavy Vehicle Simulator to improve driving safety and efficiency.

The simulator is built inside a 6,000-pound front-end cab of a real bus donated by Motor Coach Industries. It is akin to a flight simulator, which recreates a flight environment for pilot training. Drivers can turn the steering wheel, adjust the dashboard and press on the brakes and gas pedal as though it were a real bus. Views of streets and highways are projected onto the bus windshield for drivers to operate under realistic conditions. The video display simulates actual driving conditions, using accurate latitude and longitude, and a GPS locator. The simulator helps develop models of the most efficient driving behaviors for safety and fuel usage in various road and weather conditions.

Along with industry, two academic partners – the University of Idaho and Virginia Commonwealth University – are involved with the HVS project and advancements will continue to be made toward the improvement of predictive driving tools for safety and efficiency.
