The Research Of Deeply-Buried Grounding Grid In High Temperature Gas Cooled Reactor

At present, Nuclear energy is the only new energy sources which can cosmically substitute fossil fuels. In the " The National Medium and Long-Term Program for Science and Technology Development (2006-2020)" issued by the State Council(The People's Republic of China), " High temperature gas-cooled reactor nuclear power station model project (HTR-PM)" is a national major special project. Perfect grounding is the fundamental guarantee for safe operation of the electric power system in HTR-PM. And it also has the important effect in the safety, that is the important measure to ensure person and equipment's safety.The paper will provide the systematic solutions through the nuclear power plant grounding system analysis and nuclear island grounded in the practical application of engineering, I hope that it can provide some help to the design and construction of the nuclear power plant grounding system, and also can provide some reference for the development and application in the future.
