摘要
Abstract
A calculation method for the concentration distributions of radioactivity in groundwater and surface water due to a postulated WLS effluent holdup tank failure accident for One NPP under construction is introduced.After screening,the concentration distributions of radionuclides that migrated in groundwater and flowed into surface water in accident were calculated.The concentration of nuclides leaked out in accident is compared with that of normal liquid discharge in surface water.Results shows that only the radionuclide which would not be adsorbed and with long half-time might enter the surface water,but the radionuclide which would be adsorbed by bedrock will not migrated beyond the area of NPP until the radionuclide is decayed because of the slow migration rate.The increased radioactive concentrations caused by the accident discharge will not exceed distinctly the concentration resulting from normal liquid discharge.关键词
