Embodiment 1
[0018] This embodiment is a method for dynamically controlling the discharge of radioactive liquid effluents from inland nuclear power plants. The process is as follows figure 1 shown.
[0019] The basic idea of this embodiment is: take the water volume in the design base year as the dilution reference level, allocate the discharge of radioactive liquid effluents in equal proportions to the actual environmental flow, and limit the maximum discharge within the determined upper limit for control.
[0020] The steps of the method described in this embodiment are as follows:
[0021] (1) Information collection steps: used to collect nuclear power plant discharge information and basic information on downstream waters of nuclear power plants, including: historical inflow data of discharge waters, including daily average flow, annual average flow, total inflow, real-time inflow and other data, downstream The drinking water quality standard controls the concentration. Obtain basic...

The invention relates to a method for dynamically controlling discharge of radioactive liquid efflux of an inland nuclear power plant. The method comprises the steps of collecting information, determining the diluent reference level, performing equal ratio distribution on the actual environmental flow and the discharge amount of the radioactive liquid efflux and controlling implementation through the upper limit of the maximum discharge amount. By calculating the water area concentration change process, the downstream fracture surface average value appearance time probability and the maximum concentration peak are counted in the obtained discharge outlet downstream control fracture surface average concentration process, it can be seen that the dynamic discharge control mode is obviously shortened in high concentration appearance time compared with an equivalent average discharge mode, the maximum peak concentration is lower, the water dynamic dilution capability can be better efficiently utilized, reasonable control over the overhigh instant concentration peak for the mass flow appearance period of time can be achieved, and the method is used as the important basis of the liquid efflux discharge design.
Description
technical field [0001] The invention relates to a method for dynamically controlling discharge of radioactive liquid effluents in inland nuclear power plants, which is a method for optimizing the discharge process, and is suitable for optimizing the discharge process of radioactive liquid effluents in inland nuclear power plants. Background technique [0002] The radioactive liquid effluent produced by the operation of inland nuclear power plants will be discharged into the inland surface waters. Since it involves drinking water and agricultural irrigation, the concentration control requirements in the discharge waters are very strict. There are generally seasonal differences in flow rates in inland waters in my country. It is difficult to meet the concentration standard in the dry season with equal and uniform discharge, and the large flow dilution capacity in the wet season is not fully utilized. The total amount of liquid effluent discharged from nuclear power plants is ve...
