A study on the water chemistry in nuclear power plants

Significant corrosion-failures occurring in the important components or facilities in the secondary-side system cause various problems in safety due to the leakage of radioactive substances and consequently induce the reduction of the operational efficiency of the plants. In addition, the replacement of the failed components or facilities results in the tremendous expenses and a long term shutdown. The objective of the research was to ensure the safety and integrity of the plants, to improve the efficiency of the plant operation, and to prevent the shortening of plant life by improving the controlling technique of the water chemistry and minimizing the corrosion-failures in the important components and/or facilities of the plants
