The Research On The Entrainment Effect Of The Watery Intake Of The Nuclear Power Station By Applying Monte Carlo Method

The natural environment of Daya bay is superior, and the marine resources are quite abundant. There are all kinds of halobios. It is important resources to increase the innovative advantage. It has higher economic worth. Developing and protecting the marine resources in Daya Gulf is the new point of growth for Guangdong province. That the entrainment effect is produced to roe, young fish, shrimp's ovum, young shrimp near nuclear power station is an important content of environment's impacting evaluation. It is also one of the questions to which State Bureau of Environmental Protection pays close attention very much while examining and approving the report. We adopt Monte Carlo(MC ) method to carry on research to the entrainment effect in the nuclear power station of Daya bay. By using Alternating Direction Implicit(ADI) method, we solve the tide wave equation by numerical calculation and get current's velocity at any time. According to Lagrange equation of the particle's movement, we track the path of roe, young fish , shrimp's ovum , young shrimp, and calculate the entrainment effect of them because of taking water by nuclear power station. Comparing the entrainment effects calculated by MC method and transporting diffusion method, it indicates that the result calculated by using MC method is reliable for the entrainment effect of the Daya bay's nuclear power station.
