Fast neutron reactor (referred to as fast reactor) belongs to the application of the fourth generation nuclear energy system technology in the world. Compared with the second and third generation nuclear power plants currently in operation and under construction, the closed cycle of nuclear fuel formed by it can improve the utilization rate of uranium resources to over 6% (the existing nuclear power plants are only 1%, which is 6 times higher).
due to the improvement of utilization rate, relatively poor uranium mines have the value of mining. Worldwide, recoverable uranium resources will increase by thousands of times. Based on the proven natural uranium reserves, it is speculated that the use of fast reactor can make uranium resources sustainable for more than 3 years.
