What are the factors of selecting a site for nuclear power plant?
What are the factors of selecting a site for nuclear power plant?
Important considerations in site selection of nuclear power plants (NPP) are topography, accessibility, infrastructure, construction facilities, township for staff, availability of power supply, transmission lines and cooling water along with other important safety aspects related to geology, seismology and meteorologi …
Which location is suitable for nuclear power plant?
Nuclear power plants require large quantities of water for cooling purposes and are, therefore, suitably located either at coastal sites or at inland sites by the side of a reservoir or a river.
What is the ideal site for power plant?
The plant should be far away from residential area to avoid nuisance from smoke, fly ash and noise. Nature of Land : Many power plants have failed due to weak foundations. Land (soil) should have good bearing capacity to withstand dead load of plant.
Does the location of a nuclear power plant matter?
Siting is one of the important decisions in the early stage of a planned nuclear energy project. The selection and evaluation of a site suitable for a nuclear installation are crucial processes. They can significantly affect the costs, public acceptance and safety of the installation.
What are the disadvantages of nuclear power plant?
Advantages and disadvantages of nuclear power stations
| Advantages | Disadvantages |
|---|---|
| Produces no polluting gases. | Waste is radioactive and safe disposal is very difficult and expensive. |
| Does not contribute to global warming. | Local thermal pollution from wastewater affects marine life. |
What are the components of nuclear power plant?
What are the different components of a nuclear power plant?
- Pressurizer. A component of the primary cooling circuit where the liquid and vapor stages are balanced in conditions of saturation, so as to control the pressure.
- Reactor vessel.
- Fuel.
- Control rods.
- Vapor generators.
- Containment building.

- Alternator.
What is the newest nuclear power plant?
Watts Bar Unit 2
The newest reactor to enter service is Tennessee’s Watts Bar Unit 2, which began operation in June 2016. The next-youngest operating reactor is Watts Bar Unit 1, also in Tennessee, which entered service in May 1996. The U.S. Nuclear Regulatory Commission (NRC) licenses U.S. commercial nuclear reactors for 40 years.
How does diesel power plant work?
In a diesel power station, diesel engine is used as the prime mover. The diesel burns inside the engine and the products of this combustion act as the working fluid to produce mechanical energy. The diesel engine drives alternator which converts mechanical energy into electrical energy.
Which power plant has high capital cost?
Power Generation/Comparison
| Power Station | Rank | Initial Cost |
|---|---|---|
| Steam Power station | 2 | Are lower than those of Hydro & Nuclear. |
| Hydro Power station | 3 | Are very high because of dam construction. |
| Diesel Power station | 1 | Lowest compared to all other power stations. |
| Nuclear Power station | 4 | Highest due to complex nuclear reactors. |
Is it bad to live near a power plant?
A review of studies over the past 30 years provides a body of evidence that people living near coal-fired power plants have higher death rates and at earlier ages, along with increased risks of respiratory disease, lung cancer, cardiovascular disease and other health problems.
What are 5 disadvantages of nuclear energy?
Here are some of the main cons of nuclear energy.
- Expensive to Build. Despite being relatively inexpensive to operate, nuclear power plants are incredibly expensive to build—and the cost keeps rising.
- Accidents.
- Produces Radioactive Waste.
- Impact on the Environment.
- Security Threat.
- Limited Fuel Supply.
How to choose a site for a nuclear power plant?

How are nuclear power plants selected in Australia?
Within Australia the site selection for nuclear power generation would come under the guidance of our nuclear regulator ARPANSA. Some of the issues that will influence the selection of a region of interest would be: having low local population densities. containing good regional geology for foundations.
How big does a nuclear power plant need to be?
Nuclear power plants are large and are best built with multiple reactors at each site. This means the transmission lines need to be at least 330 kV and ideally 500kV. New sites will need to be located close by the grid or will require regional grid expansion to be taken into account.
How are external events determined for a nuclear power plant?
The design basis external events are determined for the combination of the proposed site and nuclear power plant. Ground water table should be low to mi nimize uplift pressu res on buildings. Availability of construction materials, are well identified. Access to site with respect to movement of persons and ODCs.
