Description

technical field [0001] The present invention relates to the field of nuclear engineering, more specifically, to an on-line monitoring and alarm device for nuclear reactor fuel damage, which is based on the nonlinear dynamics theory and its application in the operation and safety of nuclear reactors and has a self-learning function. Intelligent nuclear reactor fuel damage online monitoring and alarm device. Background technique [0002] Nuclear energy has become one of the important components of energy in our country and even in the world, so it is very important to ensure the safe operation of nuclear power plants. Nuclear reactor fuel cladding is the first barrier for nuclear reactor safety. If the cladding breaks, the radioactive fission products of nuclear fuel will be released into the coolant of the primary circuit. According to the operating regulations of nuclear power plants, when the iodine-equivalent radioactive activity of the primary circuit coolant exceeds a c...
