摘要

A method for operating a a water - steam - circuit (1) having a power station, wherein the water - steam - circuit is operated at least one with a source of heat steam generator (13) and a high-pressure part (3), wherein during a standstill of the power station, in which the heat input of the heat source into the steam generator (13) is reduced or switched off, with the following steps:– Cooling of the high-pressure part (3) to a for the high-pressure part predetermined temperature - and / or pressure level, wherein the predetermined temperature - and / or pressure level above or equal to the minimum temperature - and / or pressure level for a hot start is– Holding the predetermined temperature - and / or pressure level in the high-pressure part (3) by means of steam to be fed with steam of an external steam source (23).
