I think it goes beyond that. It's not just a "mistake." John Lennon 1941-1980 is a mistake, but at least the years 1941 and 1980 exist. Even mixing up "R" and "D" all the time is at least plausible as a "mistake" since Ds and Rs are both used.
But this? The name of this supposed reactor didn't just happen as a case of a typo or anything. This thing had to be invented out of whole cloth!
Somewhere, sometime, someone had to make up this name and claim it as a power plant. Ultimately, that had to be carried far enough so that someone at Fox transcribed it into a graphic.
So the question is, where did the notion that it was a power plant originate? Is it as noted above a practical joke played by someone in the research office, which was failed to be detected by the factcheckers? Or did they get the list from somewhere else, and simply transcribe it (at which point, it was failed to be detected by the factcheckers)?
Either scenario doesn't look good. If they got folks in the back making stuff up as a practical joke, they have just lost credibility as a serious news agency. OTOH, if they got it from a dubious news source, well then...I guess that calls into the question of their credibility.
This is not just a "mistake" as in "whoops." That this night club was listed among the Japanese nuclear power plants is a deliberate move on someone's part. That it somehow got into the Fox News office begs the question of what they use for sources. That it got through the factcheckers also tells us about their capabilities.
