A new high-purity polymer dispersant and scalp conditioner, which is introduced into the feed water supplied to the secondary line of the NPP steam generator, is proposed to minimize the accumulation of metal oxides in the NPP steam generator during the continuous operation of the generator. The high purity polymer is selected from the group consisting of acrylic acid polymer, methacrylic acid polymer, acrylate polymer, methacrylate polymer, copolymers and terpolymers, acrylate and acrylamide copolymer, acrylate and methacrylate copolymer and mixtures thereof. Methods of obtaining and using a polymer dispersant and scale air are described. Means of extraction of metal and polymer oxides from the discharge stream are considered. |
