The US is already home to some of the world's fastest supercomputers, as measured by TOP500. These supercomputers can be tasked with a variety of computational roles. Last month, Interesting Engineering reported how the Los Alamos National Laboratory planned to use a supercomputer to Although the system was expected to be operational by now, manufacturing issues delayed its completion. When ready, Aurora will displaceto become the fastest supercomputer in the world. "What’s really new with Aurora are both the scale of the simulations we’re going to be able to do and the number of simulations," said Dillon Shaver, a nuclear engineer at ANL, in the press release.

In their simulations, the researchers will look at the whirls and the eddies of heat, also known as turbulence, around fuel pins to model the heat transfer properties of the reactor. Increasing turbulence can help heat transfer, but the process also requires more energy.
