Method for prolonging the time of Overflow of Steam Generator under accident conditions of a nuclear power plant with pressurized water reactor

摘要

A method of response against accidents of plants with pressurized water reactor to Prolong the time of Overflow of Steam Generator under accident conditions of the plant.This method involves the following steps: First, an accident happens that causes the starting of The Auxiliary Pumps of Water Supply; Second: Stop The Auxiliary Pumps of Water Supply; and Third: determine if you need to restart the Auxiliary Pumps of Water Supply.The advantages are that this method can automatically adjust the supply Flow Steam Generator by increasing the control signals of Overflow Protection and extend the time of Steam Generator with the premise of ensuring the security of the core ReactorSo it can Prolong the time of operation without Operator Intervention and reduce errors by operators.
