I have completed an exhaustive search of this website, per the recommendation of BZ, to try and discover why he is so angry. And to my surprise, I could not find a rational explanation. I am sure the original poster performed a thorough search with out finding an adequate answer to his question. So like a good nuke, he asked.
Secondly, please stop calling commercial nuclear power the "Big Leagues" or the "Big Time". Granted, commercial plants are bigger and much more complex than the Navy variety but to label it as such is a little egotistical. At the end of the day, it is still a pot of hot water used to generate electricity. There are numerous other nuclear applications and processes that make what we do pale in comparison. It is a job I truly enjoy doing but don't believe it takes an extraordinary person walking among mere mortals to run a plant.
Anyone with a little aptitude, the right attitude and some hard work could easily do what we do.
