Research on Implementation Technology for Renovation of?Three Waste Treatment Control System in Nuclear Power Plants
The KSN(Three-waste Treatment Control System)of Qinshan Nuclear Power Plant Unit 2 is a digital system with functions such as operation monitoring,assistance in operation,alarm handling,and communication with the plant computer system(KIT).Due to the uniqueness of the three-waste treatment system in nuclear power plant operations,there is no full shutdown window suitable for the overall transformation of the control system(KSN),necessitating a step-by-step approach for the overall transformation of the control system.This article identifies potential difficulties in the transformation of the KSN,analyzes them,and proposes targeted solutions,ultimately successfully completing the transformation task.This article provides guidance for the overall transformation of the three-waste treatment control system in nuclear power plants and can also serve as a reference for the organization and management of similar transformations in other nuclear power units.
