They hacked into some workstations. This isn't the same as stuxnet.
Presumably this was a bug in a VPN software somewhere, which led to, probably, some windows machines. The fact that this was at a nuclear facility is kindof pointless; it's just an office.
Stuxnet specifically went after industrial control systems, and destroyed the machines they controlled.
That could also be interpreted as "someone tried to run some shellcode [that was copied from Stuxnet] on the POS Windows XP boxes we use for QA tests, so we shut down the SCADA interconnect just in case." It's pointless to speculate though. I bet it turns out to be a really stupid prank by an ex-scientist.
