ABSTRACT:
Nuclear reactor installation with a light-water reactor includes a first heat exchanger, a primary and a secondary circulatory cooling loop connected in series through the first heat exchanger, the secondary circulatory cooling loop being a main cooling system for the installation, another secondary circulatory cooling loop operatively connected to the first heat exchanger, a second heat exchanger connected in the other secondary circulatory cooling loop for providing emergency cooling, the second heat exchanger being a steam convertor or steam-to-steam heat exchanger for producing low-pressure steam at a low-pressure side thereof having an inlet and an outlet and forming part of a third circulatory loop, a feedwater source independent of the main cooling system connected in the third circulatory loop at the inlet to the low-pressure side of the second heat exchanger, the outlet of the low-pressure side of the second heat exchanger being connected to a blow-off line leading to the open air.
