Overview
The Multiphysics Methods Group (MMG) is a program at Idaho National Laboratory (under the U.S. Department of Energy) that uses modeling software to simulate complex physical and chemical reactions inside nuclear reactors. The ultimate goal of the program is to use these simulation tools to enable more efficient use of nuclear fuel, resulting in lower electricity costs and less waste products. [1]
Where it is happening
Idaho National Laboratory, near Idaho Falls, Idaho, U.S.A. is the primary facility involved. Work there began on the project in 2004.
Who is involved
Glen Hansen, is the Group Leader of 11 other members of the group who also coordinate efforts with other specialists in academia and industry.[2]
Areas of Study
The MMG focuses on problems within nuclear reactors related to its fuel and how heat is transferred inside the reactor. "Fuel degradation" refers to how uranium pellets and the rods they are encased in (several rods bundled together is what makes a "fuel assembly") eventually wear out over time due to high heat and irradiation inside a reactor.
It is also an important effort in better understanding and improving the abilities of computer modeling software that is used to predict this sort of degradation. The group states three main objectives, "The mission of the Multiphysics Methods Group is to support the INL goal to advance the U.S. nuclear energy endeavor by:
- Furthering the state of computational nuclear engineering
- Developing a robust technical basis in multidimensional multiphyisics analysis methods
- Developing the next generation of reactor simulation codes and tools [3]
The work done by the group directly supports programs such as the Light Water Reactor Sustainability Program's research into advanced nuclear fuels.
