Abstract
The invention relates to a high-temperature supercritical nuclear reactor. A spherical solid is used as a coolant of the nuclear reactor, which is different from common nuclear reactors that adopt light water, heavy water, gas and liquid sodium. The spherical solid coolant can be graphite spheres coated with silicon carbide, stainless steel spheres, graphite spheres coated with stainless steel and the like. The spherical solid has the characteristic of good rolling ability, so that the spherical solid can roll to a steam generator under the action of gravity after heating in the reactor, and the purpose of transferring heat from the reactor to the steam generator is achieved. The reactor is applicable to both thermal neutron reactor and fast neutron reactor, and natural uranium, low-enriched uranium, plutonium and thorium can be used as nuclear fuel. The temperature of high-temperature steam / water outputted by the steam generator can reach 900 DEG C, the same parameters to a thermal power station can be reached, the requirement of supercritical even ultra-supercritical can be satisfied, and the high-temperature supercritical nuclear reactor has high safety and reliability.
Description
technical field [0001] The invention belongs to the field of advanced reactor type research and design in nuclear reactor engineering Background technique [0002] The reactors currently used in nuclear power plants are mainly pressurized water reactors, a small amount of boiling water reactors and high temperature gas-cooled reactors. However, due to the potential danger of nuclear leakage in nuclear power plants, people are worried about the safety of nuclear power plants, and the development of nuclear power has been restricted. How to improve the design of nuclear power plants and improve the safety and economy of nuclear power plants is the goal of nuclear power designers in various countries. Contents of the invention [0003] The present invention adopts spherical solid as the coolant of the nuclear reactor, which is different from the general reactor which uses light water, heavy water, gas and liquid sodium. The spherical solid coolant can be graphite balls coat...
