It was about 15 years ago when I worked as a contract trainer there, had a very positive experience with a SRO-I Management Cert class. The heat and humiditiy in the summer have to be experienced to believe them.
I did some NRC exams there too, and overall the management seems to be serious about doing things right - for example, if you reported tools laying around near the Diesel, or oil leaks on it, they were genuinely glad to have the information, and when you went back the next day, the problem had been fixed.
I don't know what it's like to do an outage there.
