description A method and an apparatus are provided for the operational monitoring of a condenser including a steam chamber through which steam to be condensed flows and at least one configuration having a plurality of tubes in the steam chamber through which a coolant fluid passes from an inlet to an outlet end. The steam pressure and/or temperature is measured at least at one measuring point in the steam chamber. In addition, the inlet temperature of the coolant fluid at the inlet end, the outlet temperature of the coolant fluid at the outlet end and the coolant fluid mass throughput are measured at each selected tube. The measurements are evaluated to determine the heat transfer coefficient of each selected tube and the coefficients thus determined are assessed for diagnostic purposes. In particular, a signal is given when at least one heat transfer coefficient differs substantially from a predetermined setting.
