The invention belongs to the field of reactor safety system design, and particularly discloses a lead-bismuth reactor immersion type passive residual heat removal system and method. The lead-bismuth reactor immersion type passive residual heat removal system comprises a reactor container, a reactor core, a steam generator, a hot pool, a cold pool, an independent residual heat removal heat exchanger and an air cooler, wherein the reactor core, the steam generator, the hot pool, the cold pool and the independent residual heat removal heat exchanger are all located in the reactor container, the air cooler is located above the reactor container, the primary side inlet and outlet of the independent residual heat removal heat exchanger is connected with the hot pool, and the secondary side inlet and outlet of the independent residual heat removal heat exchanger is connected with the air cooler through a connecting pipeline. According to the invention, the primary loop natural circulation and the intermediate loop natural circulation of the lead-bismuth reactor under the accident condition are realized, the residual heat of the reactor core is taken away through air cooling, the reliability is high, the residual heat removal capability is strong, and the reactor is brought to a safe and stable state.
Description
technical field [0001] The invention belongs to the field of reactor safety system design, and in particular relates to a submerged passive waste heat discharge system and method for a lead-bismuth reactor. Background technique [0002] When the lead-bismuth pile is in normal operation, the heat generated by core fission is taken away by the steam generator. In the event of an accident, if the steam generator cannot be used, a core waste heat removal system must be configured to remove the core waste heat to prevent the core from melting and developing into a serious accident. The active waste heat removal system used in traditional reactors relies on external power. Once an external power loss accident such as a power outage occurs, the active waste heat removal system cannot normally export the waste heat from the core. Without other waste heat export measures, The core will further heat up and deteriorate and develop into a serious accident. Therefore, it is necessary t...
