During the transition process of power changes in nuclear power devices, due to the relatively lagging dynamic response of the control system, the reactor power and secondary fcircuit output power are mismatched, causing the coolant temperature and volume of the primary circuit system to change over time, and causing the pressurizer to produce a corresponding dynamic response.

摘要

During the transition process of power changes in nuclear power devices, due to the relatively lagging dynamic response of the control system, the reactor power and secondary fcircuit output power are mismatched, causing the coolant temperature and volume of the primary circuit system to change over time, and causing the pressurizer to produce a corresponding dynamic response.
