Abstract

The invention relates to a method and system for improving reliability of emergency power supplies of a nuclear power plant. At least one path of high-capacity battery energy storage system (fixed energy storage system and / or movable energy storage system) is used to supplement or replace final emergency power supplies of a nuclear power plant. When all existing emergency power supplies of the nuclear power plant fail, the system is started to supply power for equipment in an emergency plant of the nuclear power plant so as to keep discharging waste heat of reactor cores and cooling spent fuel pools of the nuclear power plant, thus ensuring the safety of the nuclear power station. The method and system provided by the invention can be used for resisting against extreme weathers and avoiding common mode failure of the emergency power supplies in the extreme weathers, can strength the reliability of the emergency power supplies of the nuclear power plant and can at least reduce the melting probability of reactor cores by 21.6%, thereby improving the integral nuclear safety level of the nuclear power plant.

Description

technical field

[0001] The invention belongs to the key technology of the million-kilowatt advanced pressurized water reactor nuclear power plant, and also relates to new high-capacity and high-power battery technology. In particular, it relates to a method and system combining the key technology of the million-kilowatt advanced pressurized water reactor nuclear power plant and the battery management technology. Background technique

[0002] A nuclear power plant is a power plant that uses the energy released by nuclear fission (Nuclear Fission) or nuclear fusion (Nuclear Fusion) reactions to generate electricity.

[0003] In order to protect the health of the staff of the nuclear power plant and the residents around the nuclear power plant, the design, construction and operation of the nuclear power plant adopt the principle of defense in depth, and provide multiple protections in terms of equipment and measures to ensure that the nuclear power plant can effectively control ...
