Pressurized water reactor system in the type of pressure pipe

Abstract

The invention discloses a pressurized water reactor system in the type of pressure pipe. A passive safety system is arranged in the pressurized water reactor system. The passive safety system includesa cooling water tank and a passive air-cooling system, wherein a reactor in the type of pressure pipe is immersed in the cooling water tank. A heat exchanger of the passive air-cooling system is soaked in the cooling water tank. On one hand, the proven technology of pressurized water reactors in the prior art can be carried on; on the other hand, the pressurized water reactor has inherent safetyand is improved in security; in addition, reactor core power density and reactor power of the pressurized water reactor are guaranteed, thus achieving excellent economic efficiency.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor engineering, in particular to a pressure tube pressurized water reactor system. Background technique [0002] Nuclear energy, as an efficient, economical, and reliable clean energy, plays an important role in optimizing my country's energy structure, ensuring energy security, reducing environmental pollution, promoting the "going global" strategy of nuclear power, and building a safe, clean, efficient, and sustainable modern energy system. important strategic significance. [0003] After the Fukushima accident, although the development of nuclear power has been affected to a certain extent, in recent years, while comprehensively improving safety standards and safety technologies, the pace of restarting nuclear power at home and abroad is gradually accelerating. A recent study by the International Atomic Energy Agency (IAEA) shows that by 2030, the growth rate of the total global nuclear po...

Problems solved by technology

[0009] The invention provides a pressure tube type pressurized water reactor system, which solves the problem that the current large-scale pressurized water reactor nuclear power technology does not meet the inherent safety characteristics, and although the high temperature gas-cooled reactor has the inherent safety characteristics, its reactor power density is very low, Compared with traditional pressurized water reactors, the technical problem of its relatively poor economic efficiency, on the one hand, it can inherit the mature technology of the current pressurized water reactors, on the other hand, it can make the pressurized water reactors have inherent safety and improve the performance of pressurized water reactors. Safety; third, maintain the core power density of the PWR and the power of the reactor, thereby ensuring a high economical technical effect
