In a nuclear reactor steam generator, water is normally circulated by a pump and in the event of failure of the latter, circulation is maintained by injection of steam into the system from an external auxiliary boiler. Over-heating due to decay energy is thereby prevented. The steam generating heat exchanger and the reactor core are mounted together within a pressure vessel and the steam and water.are pumped from the heat exchanger and are returned to it through an external steam-water drum. The auxiliary boiler is connected to the exchanger outlet header through a valve which is opened automatically upon pump failure.
