Abstract: The invention relates to a solar power plant having a first heat transfer circuit and a second heat transfer circuit, wherein the first heat transfer circuit comprises a store (3) for hot heat transfer medium and a store (5) for cold heat transfer medium as well as a pipeline system (6) leading though a solar field (7) and connecting the stores (3, 5) for hot and cold heat transfer mediums. The second heat transfer circuit comprises a pipeline system (9) that connects the stores (3, 5) for hot and cold heat transfer mediums, in which at least one heat exchanger (11) for evaporating and superheating water is accommodated, wherein the at least one heat exchanger (11) has a region flown through by heat transfer medium and a region flown through by water, which are separated by a heat-conducting wall so that heat can be transferred from the heat transfer medium to the water. Each heat exchanger (11) comprises a break detection system (21), by which a possible break of the heat-conducting wall can be detected, and valves (23) for closing feed lines (13, 17) and discharge lines (15, 19) for the heat transfer medium and water, wherein upon detection of a break, the valves (23) in the feed lines (13, 17) and the discharge lines (15, 19) are closed for heat transfer medium and water.
