Development Progress and Prospect for Industrial Application of the 200MW Low Temperature Nuclear Heating Reactor

The technology for the low temperature nuclear heating reactor (NHR) is developed independently and its property right is completely owned by China. The advanced technology, such as natural circulation at full power level, passive safety systems and control rod hydraulic driving, are adopted in the design of the vessel type NHR. This type of NHR is with the characteristics of high safety, reliable operation, complete isolation measures for the radioactivity, and it can be located very close to the user. It can be applied in various fields and can bring fine social and economic benefits by widely using of this new technology, especially the application in the seawater desalination. Nuclear seawater desalination is one of the effective ways to solve the problem of water shortage. The retrospection of R&D on the NHR in China is discussed. The main technical and safety features of NHR are summarized. The economic benefits using NHR to replace fossil-fired boilers are analyzed and the prospect is forecasted in this paper.
