3.3.2.4 Safety Relief Valve System
The safety relief valve system (Fig.
3.25
) consists of the safety relief valves, the
relief lines and steam quenchers which are located in the core flooding pools.
They act in case of:
- overpressure to protect the pressure boundaries (pressure relief)
- the water level in the reactor pressure vessel falling below specified limits (loss
of coolant accident, automatic depressurization)
- turbine trip (short term removal of excess steam)
- severe accident mitigation (depressurization).
