AI Technical Summary
Technical Problem
The traditional reactor coolant main pump active venting operation adds about 13 hours to the unit's operating time, reduces unit availability and power generation economic efficiency, and increases the risk to operation and maintenance personnel.
Method used
By performing vacuuming, water filling, static venting, and monitoring the gas content of the primary loop system of the nuclear power plant, and operating in SI mode under certain conditions, the main pump can be started directly, and the active venting operation can be canceled.
Benefits of technology
Shorten the overhaul period, improve the inherent safety and operation and maintenance efficiency of the unit, and reduce operation and maintenance risks and costs.

Abstract
The application provides a control method and device for canceling active exhaust of a reactor coolant main pump and a computer readable storage medium, and comprises: performing vacuumizing operation on a primary loop system of a nuclear power plant; filling water to the primary loop system after the vacuumizing operation is completed and developing static exhaust; monitoring the final gas content of the primary loop system, and if the final gas content meets a preset condition, controlling the low-pressure safety injection to operate in an SI mode; and after the low-pressure safety injection operates in the SI mode, directly starting the main pump to replace the execution of the active exhaust operation. The operation method, device and computer readable storage medium for canceling the active exhaust of the reactor coolant main pump can improve the technical problem of additional time limit.
