Patent

CA 2547942

A novel high-purity polymer dispersant and sludge conditioner added to the feedwater entering the secondary side of a nuclear steam generator for minimizing the accumulation of metal-oxide deposits within the nuclear steam generator during the continuing operation of the generator is disclosed. The high-purity polymer is selected from a group consisting of acrylic acid polymer, methacrylic acid polymer, acrylate polymer, methacrylate polymer, copolymers, and terpolymers, acrylate/acrylamide copolymer, acrylate/methacrylate copolymer, terpolymers, and mixtures thereof. Methods of making and applying the polymer dispersant and sludge conditioner are described. Means for removing the metal oxides and polymer from the blowdown stream are disclosed.

L'invention concerne un nouveau dispersant polymérique à haute pureté et un conditionneur de boue ajoutés à l'eau d'alimentation entrant dans le côté secondaire d'un générateur nucléaire de vapeur pour réduire au minimum l'accumulation de dépôts d'oxyde métallique à l'intérieur du générateur nucléaire de vapeur durant le fonctionnement continu du générateur. Le polymère à haute pureté est choisi parmi le groupe formé par un polymère d'acide acrylique, un polymère d'acrylate, un polymère de méthacrylate, des copolymères et des terpolymères, un copolymère d'acrylate/acrylamide, un copolymère d'acrylate/méthacrylate, des terpolymères et des mélanges de ces composés. L'invention porte également sur des méthodes de fabrication et d'application du dispersant polymérique et du conditionneur de boue, ainsi que sur les moyens d'extraire les oxydes métalliques et le polymère du flux d'évacuation.
