LOL. I call BS. So a radioactive steam line rupture is not more dangerous that a plain H20 steam rupture? If I am doing damage control in an engineering space just the thought of radio active steam flying around scares the sh!t out of me. On a normal boiler powered ship it is a 5 minute crises after isolation and shut off. On a nuc reactor that is catastrophic......
I spent 9 years in submarine enginerooms. Your mileage may vary.
