Risk analysis
Yes, because there's never ever been a major accident in ANY modern industrial complex run by a western company because every thing is engineered so well now.... Hello? Deep water horizon called you say? Massive contamination was it? Ah, thanks for the update.
As with the Deep Water Horizon, the Piper Alpha and Chernobyl the safety systems were disabled by human beings. No matter how clever the system is there will be a human dumb enough to bypass it. Although modern safety systems make the possibility of an accident very small, if the severity means that an area the size of Scotland has to be evacuated the risk is just not worth it to a lot of people.
