The program maintenance is in accordance with the effective maintenance procedures. In the second phase of a nuclear power project, the radiation instrument includes two types: the plant radiation monitoring system (KRT system) and the entrance and exit control system (KZC system). The KRT system and the KZC system consist of fixed instrument portable instruments. The following is an analysis of the maintenance of the instrument program.
The fixed instruments in the KZC system mainly include personal dose management system, systemic pollution monitor, vehicle and personnel monitoring system. Each set of instruments is mainly composed of detectors, measuring components and processing display units.
Portable instruments in KRT system and KZC system include C dose monitor, A, B surface pollution monitor, etc. Each instrument consists of detector, measuring circuit, processing display plug-in and so on.
Basic requirements for instrument troubleshooting: In order to maximize the operational efficiency of the radiation monitoring system, ensure that the system instrument has normal monitoring functions, protect the radiation safety of workers and the operational safety of the power plant, the basic requirements for instrument troubleshooting of the radiation monitoring system are Fast, timely, effective and reasonable.
Programmatic overhaul is to carry out programmatic overhaul of the faults of each unit of the radiation monitoring system in accordance with the effective maintenance procedures. The fault type of the instrument is repaired according to the corresponding repair procedure, which minimizes the inspection time and improves the maintenance efficiency.
At the same time, it is convenient for scientific management of maintenance work. The radiation instrument with bus structure and modular design lays the hardware foundation for the program maintenance and repair of the instrument fault. This design allows us to quickly determine the faulty component and perform timely as long as it operates according to reasonable maintenance procedures. Overhaul.
