Abstract:

Taking the AP1000 nuclear power unit as an example, this paper calculated the addition dosage of secondloop system in operation mode and shutdown mode of condensate polishing system (CPS), and obtained the theoretical add amounts of ammonia and hydrazine when the unit is running, which provided a reference for the dosing system design and configuration of secondloop of AP1000 nuclear power unit.
