Description

technical field The invention relates to nuclear power plant equipment, in particular to nuclear power plant waste gas treatment equipment, in particular to a complete set of equipment for normal temperature delay treatment of high-level radioactive waste gas from a pressurized water reactor nuclear power plant. Background technique As we all know, my country's nuclear power industry has gone through more than 20 years of development. At present, the nuclear power plants that have entered commercial operation mainly include: Qinshan Phase I, Phase II, and Phase III, Daya Bay, Ling Ao Phase I, Phase II and Hetian Bay Nuclear Power Plant. The total amount accounts for 1.9% of the country's total power generation, while the global average nuclear power has accounted for 16% of the total power generation, of which the proportion of nuclear power in the United States, Japan, and France has reached 20%, 30%, and 80% respectively. There is still a big gap between my country's nuclea...
