Abstract: Boron alkali curve is an important control basis for water chemistry in the primary loop of nuclear power plant. Selecting a scientific and reasonable boron alkali curve is of great significance to reduce the deposition of corrosion products in the primary loop and the reduction of radioactive source terms. This paper first analyzes the purpose of primary loop water chemistry control, and analyzes the factors considered in the selection of primary loop pHT; secondly, this paper reviews the development history of boron alkali curves, focusing on the analysis of the characteristics of boron alkali curves of different reactor types in China; and finally, suggestions for the application of boron alkali curves in domestic nuclear power plants is put forward in this paper.

Key words: boron alkali curve, nuclear power plant, chemical control, radioactive source term
