In 1988, there was a steam line failure at the Mohave station in Nevada, USA. The hot reheater P11 pipe failed , at 31 bar,g and 593 C temp ( design temp was only 540 C, and it was overheated for 1 yr prior to failure). It failed outside of the plant cafeteria, and killed 11 operators who were eating lunch in the cafeteria.
