description The invention relates to the technical field of nuclear power station primary loop main pumps. The invention discloses leakage abnormity processing system and method for a main pump of a nuclear powerstation. The system comprises a main controller, a nuclear power station main pump and a liquid collection tank, wherein the nuclear power station main pump comprises a second shaft seal and includesa leakage pipeline which is used for connecting the second shaft seal with the liquid collecting tank; an impurity isolation valve is arranged on the side, close to the second shaft seal, of the leakage pipeline. At least one water filling isolation valve is arranged on the leakage pipeline between the impurity isolation valve and the liquid collection tank; the liquid collecting tank is providedwith a water supplementing isolating valve used for controlling reverse water filling and exhausting, and the main controller is used for controlling the water supplementing isolating valve and at least one water filling isola
