Nuclear power plants are designed, constructed, operated and inspected to prevent pipe ruptures. Despite these preventive measures, plants are designed to mitigate the effects of hypothetical pipe ruptures. The hypothetical ruptures are in the form of leakage cracks and, for high energy lines (operating temperatures in excess of 200 degrees F or operating pressures in excess of 275 psig), full circumferential and longitudinal breaks. Nuclear power plants are designed to achieve a safe shutdown if such a postulated high energy line break (HELB) was to occur.
