摘要

Procedure for cleaning and conditioning the water-steam circuit of a power plant, in particular a nuclear power plant, in which - during the production operation, an amine is added to the working medium that circulates in the water-steam circuit as a film-forming material, which forms a hydrophobic film on the circuit surfaces, - monitoring the concentration of the film-forming material at least in the feed water of the steam generator, during measurements, characterized in that - during the duration of the procedure, the concentration of at least one impurity contained in the working medium at least in the feed water of the steam generator is monitored, - the concentration of the film-forming material is modified according to the concentration of the at least an impurity, reducing the dosage rate of the film-forming material in case of an increase in the concentration traction of the at least one impurity.
