Description

technical field [0001] The invention relates to the field of nuclear power reactor coolant hydrogenation systems, in particular to a coolant hydrogenation system and method for small reactors. Background technique [0002] During the operation of pressurized water reactor nuclear power, the coolant in the reactor coolant system (hereinafter referred to as the primary circuit) will be decomposed into hydrogen and oxygen under irradiation conditions. Oxygen will aggravate material corrosion, reduce equipment reliability and increase radioactive activation. product. At present, nuclear power plants generally use the primary loop hydrogenation technology, which suppresses the radiation decomposition of water by adding hydrogen to the coolant and maintaining a certain hydrogen concentration in the coolant. [0003] In the prior art, boron addition is basically used to control reactivity in land-based nuclear power plants. During the power operation of nuclear power plants, the a...
