One of the main driving factors behind supercomputer development, in the 80s and 90s were the need to have machines powerful enough to simulate a nuclear explosion. I believe that nowadays they have machines, at least from ~2000 or so which are able to simulate such stuff pretty fast.

The modern ones, like "K" would probably be used in economic and weather forecasting...apparently weather forecasting with certainty is still beyond our current computing power...some experts suggest that we might need at least 1 Exaflop to predict a week's weather with certainty(or to the level theoretically predictable).
