How do you test diesel generators which back up a nuclear reactor? I understand you do it during the plant downtime, but don’t you require something at the other end of the network that consumes the 1GW you generate?

I don't have actual knowledge of nuclear power plants, that is classified beyond the public. However hospitals do the above, because if thing dont work on a bright sunny day how do you think they will work when a tornado has not only taken out power, but also filled the er with server trauma cases.
