True, but remember, it's kind of hard to hide the fact that the pressure vessel head was not tightened down properly. What actually happened was not any real concern. The plant was safed and the problem was found and rectified. However, the fact that it happened at all is the real problem. Forgetting to tighten down a bolt here or there should never happen, but it does. Forgetting to tighten to actual vessel head??
