35 Nuclear power plant water intake environmental impact analysis
5.1 Purpose of evaluation
The overall goal of the water impact analysis is to obtain sufficient environmental impact information to determine the cooling water intake of the nuclear power plant.
The location, design and construction of the facility reflect best practice techniques with minimal environmental impact. For new water intake facilities, it should pass
Obtaining credible loss of biological data by comparing historical data, pre-operational survey data, and other nuclear power plant operating experience
Estimate. For existing nuclear power plants, combined with monitoring data, the amount of biological loss caused by credible water withdrawal is given, and evaluation has occurred.
And possible long-term effects.
5.2 Analysis and demonstration process
In the preparation of the environmental impact report of the site selection site of the nuclear power plant, the method of collecting data may be used, according to the characteristics of the site.
Determine the cooling method and determine the potential impact of water withdrawal. When the potential impact of water withdrawal is unacceptable, the cooling method needs to be modified or re
Determine the site.
When preparing the environmental impact report for the construction phase of a nuclear power plant, the impact of water abstraction is initially determined based on the collected data.
The case of determining that the water intake of the site is less affected includes. the water intake is small (such as the water taken by the secondary circulation cooling system) and the water intake zone is raw.
The amount of material is low; historical data shows that there is no water intake effect; or other conditions with less influence on water withdrawal. In addition to the above,
It should be preliminarily determined that the impact of water intake at the site is large. For sites with less impact on water withdrawal, collect the necessary information for a brief synthesis
Impact analysis; a relatively extensive on-site investigation is required for the initial determination of site requirements that have a large impact on site water withdrawal.
Through literature research, on-site investigation and experimental research, estimation or model simulation, analysis and evaluation of the impact of water intake environment,
Determine the impact of water intake and best practices.
When preparing the environmental impact report of the nuclear power plant operation phase, the drainage plan and design parameters should be constructed according to the project.
Confirm and review the impact of water withdrawals and best practices based on up-to-date environmental data (such as changes in the construction phase).
The environmental impact analysis and demonstration process of the nuclear power plant water intake facilities is shown in Figure 1.

And the investigation time, the biological analysis plan of the main analysis area and the far field analysis area is given, and the biological investigation is carried out (see Appendix A);
b) Evaluation based on the number of days, nights and seasonal changes in the number, size and weight of organisms affected by the operation of the water intake facility

The impact of water abstraction on many biological species may be lower than the lower limit of detection of survey methods and analytical techniques. For such species,
A general survey is generally not required unless it is used to determine best practice techniques. At the same time, you can consult the aquatic biologists.

5.5 Best Practice Technology Decision
5.5.1 Best Practice Technique Determination Method

The main considerations of the evaluation include. the main spawning ground, the feeding ground, the wintering field and the migratory route, etc.
Stock and other key functions in the life process.
Whether the water intake facility is a best practice technique, the biological value-potential impact determination method is shown in Table 1, and the determination step
as follows.
7 Table 1 Biological value - potential impact determination method
High cooling water flow
(relative to the water supply body)
Low cooling water flow
(relative to the water supply body)
High biological value is not unknown
Low biological value is unknown
a) It is generally not a best practice to build a DC cooling water intake system in a region with high biological value unless
Prove that there are fewer or more species that are affected by water abstraction and will not cause the population to decrease;
b) It is generally best practice to construct low-flow water intake facilities in low-value areas, unless water intake facilities are visible
Rare and endangered species;
c) Under the combination of other relative biological value-cooling water flows, it is difficult to directly determine best practice techniques. In this situation
Under the circumstance, it is required to provide sufficient survey data of aquatic organisms, complete the environmental impact assessment of the water intake facilities, and comprehensively consider the economic factors.
The level of technology and technology determines the best practices that make the overall impact of water intake location, design and construction on the environment small.
5.5.2 Optimization steps for water intake facilities
The steps for optimizing the water intake facilities are as follows.
a) Whether the impact can be reduced by modifying the filtration system;
b) whether it is possible to reduce the impact by increasing the size of the water intake facility (ie reducing the maximum flow rate through the filter);
c) consider other engineering and management measures to reduce the impact of water abstraction;
d) consider abandoning existing water intake facilities, constructing new water intake facilities in another location, and introducing them when new water intake facilities are built
Proper design to reduce the environmental impact of water withdrawal;
e) If the above technologies are unable to reduce the environmental impact, the water withdrawal can be reduced by increasing the condenser or heat exchanger.
The temperature difference at the outlet is either achieved by a secondary circulation cooling water system.
