STUDY ON OVERALL CONCEPTUAL SCHEME OF INTELLIGENT OPERATION AND MAINTENANCE SYSTEM FOR MOBILE SMALL MODULAR REACTOR BASED ON SYSTEM ENGINEERING METHOD

抄録

The small module reactor has the characteristics of high energy density and long-term stable operation. It can be used as an energy supply device to supply power for mines, islands, scientific research and national defense equipment located in remote/closed areas. The main deployment scenario of small module reactor is remote areas with weak infrastructure such as transportation, water source and power supply, which puts forward high requirements for the safety, reliability, flexibility, robustness, rapid deployment and "unattended" capability of reactor operation. It is important to study the intelligent operation and maintenance system of mobile small module reactor (SMR) that can realize the ability of "unattended monitoring". However, the research on intelligent operation and maintenance system of SMR belongs to innovative research. From the perspective of demand, it should be designed in a positive iterative way to form an overall conceptual scheme, laying the foundation for the subsequent preliminary design and detailed design.

System engineering method is a forward design method suitable for complex systems, which is widely used in aerospace and other industrial manufacturing fields. At present, the application of system engineering method in the field of nuclear power is in the exploratory stage. This paper studies the applicable system engineering method for the intelligent operation and maintenance system of SMR, and gets the overall conceptual design the intelligent operation and maintenance system of SMR based on this method. The overall conceptual design of SMR intelligent operation and maintenance system based on system engineering is a beneficial attempt to apply system engineering method to the forward design of nuclear power system.
