Abstract

Abstract

Nuclear power plants gradually adopt the long-term fuel cycle, the power density of the reactors is increasing and the level of burnup is higher. It is more complex and difficult to control the primary coolant chemistry. The water chemistry of enriched boric acid in primary coolant was calculated. Results show that the use of EBA for 40% enrichment can reduce the initial concentration of boron and improve the p H value of primary coolant, enabling the core of reactor to operate at p H^300℃7.2 to 7.4.
