Design And Construct Of Communication System Of Nuclear Power Plant

The communication system is the key system in a nuclear power plant for information transfer under both normal and emergent situations and a solid guarantee for the proper operation of the plant as well. Nuclear power plant development went through the phases of Generation1, Generation2, Generation2+and Generation3for now. After the Fukushima nuclear accident, the safety issues of nuclear power plant again attracted global attention.The primary works in this thesis are presented as follows:(1) The current design situation of nuclear power station at home and abroad is discussed; networking module and industry radiation resistant closed circuit module of different reactors are compared.(2) Analysis of the setting requirements of the system and offered the overall design of the communication system under the overarching principles.(3) The framework of networking module have been improved, networking scheme of digital IP network first, analog signal second have been achieved. The design of routes between switchboards was also advanced.(4) Difficult points of industry radiation resistant closed circuit are analyzed and contrast variety of industry radiation resistant equipment. Design Project is improved, reliability of industry radiation resistant closed circuit system is enhanced.This thesis combined(Fukushima nuclear accident nuclear power plant to improve general technical action request)) issued by National Nuclear Safety Administration after Fukushima nuclear accident. Improved the design of networking module and industry radiation resistant closed circuit module. Variety of ways and routes will be offered by the communication system, the requirement of National Nuclear Safety Administration for new nuclear power station at home is achieved.
