Any Jobs on DICE For Nuclear Bomb Designers?

Slate is running an interesting article -- seems like the number of people in the United States that design nulcear weapons "could all fit on a bus" according to the story. And most of those are near retirement age. So what happens when these guys are gone? While it would be a great thing to get rid of all nuclear weapons, would it be such a good idea to lose all your exertise before that day happens?
