If they caught something like this on an ORSE then they probably lost their "reactor keys" underway and had to return to port on the diesel. Ouch! In any case, I would not want to be in the Engineering Department of that ship right now. Their lives are going to be hell for the next year or two. I don't feel that bad for them though. Every EOOW, EWS, EDO, and EDPO had to know what was going on or at least suspected that the logs weren't being maintained. I don't think they were necessarily complicit, but I do think they probably had the attitude that they didn't want to know.
Let's just say that Naval Reactors isn't going to be happy that there is now an international news story that says that the crew "failed to do daily safety checks on its nuclear reactor for a month and falsified records to cover up the omission." Nope, Adm. Donald will probably not be amused.
