Zusammenfassung:In a nuclear reactor installation, a steam generator is positioned inside of a containment and has a live-steam pipe leading out of the containment. The pipe has a fast-acting shut-off valve shunted by two pressure-responsive safety valves having a smaller flow rate capacity than the shut-off valve. When the fast-acting shut-off valve is suddenly closed, the two safety valves relieve the pressure of the steam stopped by the shut-off valve. The two safety valves respond to differing steam pressures.
