In the next dozen years, China will build at least 27 million-kilowatt nuclear power plant, with 18 nuclear power plants under construction in a total of nearly 50 nuclear power plants need nuclear grade graphite gasket. Nuclear power plant nuclear grade graphite gasket is widely used in modern nuclear power plants operating system, play a crucial role in the safe operation of the nuclear power plant system, it can guarantee nuclear power plants operating system in the case of alternating temperature and pressure, the Department of the leakage rate 10-7 Pa? m3 / s or less, according to international standards is a zero leakage; it in a nuclear power plant, the number of applications and it is important, every one million of the pressurized water reactor nuclear power plant nuclear power system only pipe flange connections necessary to use more than 3,000 , and are therefore promising market.

 Nuclear grade graphite gasket in the nuclear power plant as an attachment, but it is vital. Gasket relative to the petrochemical equipment, nuclear grade gasket to meet high temperature, high pressure, thermal fatigue harsh working conditions, but also must have the resistance to radiation, high reliability, high life expectancy and nuclear grade cleaning requirements, the need to go through the compression rate, spring rate, stress relaxation rate and maximum leakage rate of a number of technical performance testing and thermal alternating test to be applied to the nuclear power plant license. Graphite gasket used in nuclear power plants, is the highest level of performance, quality gasket, long time, because only the United States, France 3 production of nuclear grade graphite gasket all dependent on imports, the price is expensive. Enterprises should speed up the research and development efforts in order to speed up the process of nuclear power equipment.
