The Program Decision Analysis Of Water Intake And Drainage Project Of Z Nuclear Power Plant

Nuclear power is as a kind of security,economic,clean energy.With the rapid development of China's nuclear power plant,the national pay more and more attention on the security of nuclear power water intake and the influence of the warm discharge water to the environment.The waterintake and drainage project will cost lost of money and the project implementation is complex,The investors how to ensure the safety of wateintake of the nucler power plant and the economic benefit,and also to decrease the influence to the surrounding environmentas and the stakeholders as far as possible is particularly important.So,the research on the waterintake and drainage project to provide the reasonable and scientific decision basis for the deciders is necessary.This paper is based on the waterintake and drainage project of the Z the nuclear power project,to exploring study on the decision analysis of the water intake and drainage project of nuclear power plant.Firstly,this paper considers on the natural environment condition and the requirements of design of the watersintake and draining project of the Z nuclear power plant,to list lot of possible solutions on watersintake and draining project by the brainstorming method and expert consultation method.Screening decision factors according to the requirements of national laws and regulations and advisory opinions.Sampling hierarchy process and fuzzy comprehensive evaluation method build decision model,use the technology of numerical simulation and physical model test and comprehensive consideration for the safety of waterintake,the protection of ecological environment,the coordination to stakeholder,social and economic factors and so on,to the carry ot the feasibility analysis on the solutions on watersintake and draining project.And then comparison and choose the best solution.Secondly,this paper respectively from the rationable of influencing area of cooling water,the affection of the ecological environment,the safety of navigation,coordination of stakeholders to evaluate on the optimum waterintak an drainage project.Finally,this paper summarizes the project decision analysisof the waterintake and draining of the Z nuclear power project.This paper could provide project decision-making basis.for investors.At the same time,it could provide the reference for other domestic nuclear power plant on decision analysis of waterintake and draining project.
