The present invention relates to a method for reducing corrosion erosion in the feeder pipes (12a, b) used in the primary loop of a CANDU* type nuclear power plant. According to the present invention, to this end the surface roughness of the primary side inside walls of the heat exchanger tubes (22) of a steam generator (20) that is arranged in the primary loop, which is caused by operation of the nuclear power plant, is reduced by treatment with an abrasive. *CANDU is a registered trade-mark of Atomic Energy of Canada Limited.
