Abstract

The invention relates to a solar power plant with a first heat transfer medium circuit and with a second heat transfer medium circuit, in which the first heat transfer medium circuit comprises a store (3) for hot heat transfer medium and a store (5) for cold heat transfer medium and also a pipeline system (6) connecting the stores (3, 5) for hot heat transfer medium and for cold heat transfer medium and leading through a solar array (7), and the second heat transfer medium circuit comprises a pipeline system (9) connecting the stores (3, 5) for hot heat transfer medium and for cold heat transfer medium and in which at least one heat exchanger (11) for the evaporation and superheating of water is accommodated, the at least one heat exchanger (11) having a region through which the heat transfer medium flows and a region through which water flows, said regions being separated by a heat-conducting wall, so that heat can be transmitted from the heat transfer medium to the water. Each heat exchanger (11) has a break detection system (21), by means of which a possible break of the heat-conducting wall can be detected, and valves (23) for the closing of supply lines (13, 17) and outflow lines (15, 19) for heat transfer medium and water, upon the detection of a break the valves (23) in the supply lines (13, 17) and outflow lines (15, 19) for heat transfer medium and water being closed.
