The basic concept to ensure the integrity of components during operation

The integrity of components which are relevant to safety is one of the most important prerequisites for the safe operation of a power plant. A systematic way of proceeding can be achieved by the basic safety concept. In doing so attention has to be paid to the balanced application of the so-called 'redundant measures'. Using the pressuriser spray system of a nuclear power plant as an example, the relevant factors of influence and the way of proceeding are demonstrated for piping system components which are important to safety.
