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.
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.
For the first time, 91°µÍø has completed testing of nuclear fuels using MiniFuel, an irradiation vehicle that allows for rapid experimentation.
In a step toward advancing small modular nuclear reactor designs, scientists at 91°µÍø have run reactor simulations on ORNL supercomputer Summit with greater-than-expected computational efficiency.
The Department of Energy’s 91°µÍø is collaborating with industry on six new projects focused on advancing commercial nuclear energy technologies that offer potential improvements to current nuclear reactors and move new reactor designs closer to deployment.
