The eight countries that have mastered fast reactor technology are: the United States, the United Kingdom, France, Japan, Germany, Russia, Italy, and China. The details are as follows:
1. Power reactor spent fuel reprocessing technology: Nuclear power plants generate energy through the fission reaction of nuclear fuel in the nuclear reactor. The nuclear fuel cannot maintain the rated power after 3 to 4 burns and needs to be replaced. Nuclear fuel assemblies are called spent fuel. The spent fuel is extracted from unburned nuclear fuel and newly generated nuclear fuel through a chemical process to make the fuel components required for nuclear power plants. After 24 years of testing, China finally broke through the entire technical system.
2. Fast reactor technology: Fast neutron reactor (fast reactor for short) is an application of the fourth-generation nuclear energy system technology in the world. Compared with the second-generation and third-generation nuclear power plants currently operating and under construction, , the closed cycle of nuclear fuel formed by it can increase the utilization rate of uranium resources to more than 60% (the existing nuclear power plant only has 1, which is a 60-fold increase).
3. Major Events in China’s Experimental Fast Reactors
In 1986, the 863 Plan was implemented and pre-research on the “fast breeder reactor” project began
China in December 1995 The experimental fast reactor project was approved
In August 1997, the China Experimental Fast Reactor was listed as a major project of the 863 Program
In May 2000, the first container of concrete was poured on the nuclear island
The nuclear island plant was capped in August 2002
In August 2005, the installation of the reactor body began
In June 2007, the installation of internal components was completed
In 2007 Interchange adjustment in the main control room in July
Completed the installation of analog components in December 2007
In December 2008, the installation of the entire plant was completed, and comprehensive cooling began
2009 In March 2009, the air tightness test of the reactor body was completed
In April 2009, the cold debugging was completed and the hot debugging began
In August 2009, the hot debugging was completed and the first charging was completed Conditions
First loading in June 2010
First critical in July 2010
