Method of establishing natural circulation of a liquid metal coolant in a fast neutron reactor

摘要

The invention relates to the field of nuclear engineering and can be used in establishing the natural circulation of a liquid metal coolant in the cooling loop of a fast neutron reactor. In order to generate a dynamic circulatory pressure without using pumping equipment and to provide the required direction of natural circulation of a liquid metal coolant in the cooling loop of a fast neutron reactor in the absence of heat transfer from the reactor, the piping and equipment of the upward portion and the downward portion of the loop prior to being filled are preheated electrically to a temperature of T
