IIRC, the original software pretty much has to run as-is until the day the nuclear power plant gets retired - typically 40 years, at least.

- flatfilefan 8y agoWhat about the bit rot, decay, half life and all that?
- southern_cross 8y agoAs I understand it, the software itself never really gets changed, because if it did then the whole plant might have to undergo testing and regulatory approval again. But the reactors get shut down periodically (every three years, maybe) for refueling, so the control hardware undergoes routine maintenance at that time. Or something like that.
