Sorry but in this scenario maintaining a 5-person skilled IT department was/is imperative. The TCO should of the IT department, even if you hire D. Hartmeier[1] to configure the firewalls, should be negligible compared to the operation's TCO. That said, in this case I believe that the software to manage the centrifuges is made by Siemens (Germany) and it's written on Windows. So partially it wasn't the consumer's choice to use windows. Even if they used linux, is not hard to think that the NSA could have written a Linux clone worm. The only thing that can keep away such threats is "security" as Schneir mentions here[2] "security is a process" and that process can secure any operating system out there imho.
