VERA, the Virtual Environment for Reactor Applications

Nuclear scientists at 91°µÍø have established a Nuclear Quality Assurance-1 program for a software product designed to simulate today’s commercial nuclear reactors – removing a significant barrier for industry adoption of the technology.

As scientists study approaches to best sustain a fusion reactor, a team led by 91°µÍø investigated injecting shattered argon pellets into a super-hot plasma, when needed, to protect the reactor’s interior wall from high-energy runaway electrons.

Students often participate in internships and receive formal training in their chosen career fields during college, but some pursue professional development opportunities even earlier.

Researchers at ORNL and the National Renewable Energy Laboratory took inspiration from flying insects to  a miniaturized gyroscope, a special sensor used in navigation technologies.

The U.S. Department of Energy announced funding for 12 projects with private industry to enable collaboration with DOE national laboratories on overcoming challenges in fusion energy development.

Fusion—Heating the core

In a recent study, researchers at 91°µÍø performed experiments in a prototype fusion reactor materials testing facility to develop a method that uses microwaves to raise the plasma’s temperature closer to the extreme values

Ask Tyler Gerczak to find a negative in working at the Department of Energy’s 91°µÍø, and his only complaint is the summer weather. It is not as forgiving as the summers in Pulaski, Wisconsin, his hometown.

Tungsten tiles for fusion

Using additive manufacturing, scientists experimenting with tungsten at 91°µÍø hope to unlock new potential of the high-performance heat-transferring material used to protect components from the plasma inside a fusion reactor. Fusion requires hydrogen isotopes to reach millions of degrees.

Desalination process

A new method developed at 91°µÍø improves the energy efficiency of a desalination process known as solar-thermal evaporation. 

Nuclear—Tiny testing fuels

For the first time, 91°µÍø has completed testing of nuclear fuels using MiniFuel, an irradiation vehicle that allows for rapid experimentation.
