Q & A

What is a nuclear power plant (PLTN)?

A nuclear power plant (PLTN) is a facility that generates thermal power using one or more nuclear reactors as its heat source.

How does a nuclear power plant generate electricity?

A nuclear power plant generates electricity by using nuclear fission to produce heat, which converts water into high-pressure steam that drives turbines connected to generators.

What was the first nuclear power plant to generate electricity?

The first nuclear power plant to generate electricity was located in Tennessee, USA, and it began operations in September 1947.

What are the primary materials used as fuel in a PLTN?

The primary fuel used in a nuclear power plant is uranium, typically formed into cylindrical fuel rods.

What are the environmental benefits of using nuclear power?

Nuclear power produces low carbon emissions, does not contribute to air pollution, and requires less land area compared to other renewable energy sources.

What are the potential hazards associated with nuclear power plants?

The potential hazards include radioactive waste disposal, the risk of nuclear accidents, and the long-term health effects from radiation exposure.

What is the process of decommissioning a nuclear power plant?

Decommissioning involves safely shutting down the plant and managing radioactive waste, which requires significant time and financial resources.

How does the cooling system work in a PLTN?

The cooling system condenses the steam back into water after it has been used to turn the turbines, allowing the water to be reheated in the reactor for continuous operation.

What role does the control rod play in a nuclear reactor?

Control rods regulate the nuclear reactions by absorbing free neutrons, thus controlling the amount of fission occurring within the reactor core.

Why is public perception a challenge for nuclear energy adoption?

Public fear of radiation hazards and the potential consequences of nuclear accidents have hindered the widespread adoption of nuclear energy, despite its benefits.
