I don't know - safety is top of the list:

"to assure the safety and security of our (weapons) stockpile," said D'Agostino. With its extraordinary speed it will be able to simulate the performances of a warhead and help weapons scientists track warhead aging, he said

Anastasio said the computer, in its unclassified applications, is expected to be used not only by Los Alamos scientists but others as well. He said there can be broad applications such as helping to develop a vaccine for the HIV virus, examine the chemistry in the production of cellulosic ethanol, or to understand the origins of the universe.

emphasis mine.

It will also be used for much much more. Not bad considering that much discovery was based on military needs throughout our history. The government pays for it based on military need (safety of soldiers, weapons, etc) and the civilian world benefits from it in other applications.
