For this purpose, according to the invention active cooling of the casing shell () is provided, at least one of the casing segments which form the casing shell being provided with a number of integrated cooling channels (). When the steam turbine () is operating, therefore, the casing shell () is actively cooled with a cooling medium by the latter being supplied to the cooling channels ().
