1. Basic principles of nuclear power generation
Nuclear power uses the nuclear fission chain reaction of radioactive materials such as uranium.
- Nuclear fission: When a neutron strikes the nucleus of a heavy atom, such as uranium-235, the nucleus splits, releasing two or three new neutrons along with a huge amount of heat energy.
- Chain reaction: The neutrons released at this time collide with another uranium nucleus, causing nuclear fission, and this process is repeated over and over again, which is called a nuclear fission chain reaction.
- Heat energy generation: The heat energy generated during the nuclear fission process is very large, and this energy is used to boil water to create steam.
- Power Generation: The high temperature and high pressure steam that is created rotates a turbine, and electricity is generated through a generator connected to the turbine.
2. Major facilities of nuclear power plants
- Reactor: The core facility where the nuclear fission chain reaction occurs. It consists of nuclear fuel (mainly uranium), neutron moderator, and control rods.
- Nuclear fuel: Uranium fuel, which causes nuclear fission, is processed into fuel rods and placed in a nuclear reactor.
- Moderator: A substance that slows down the fast neutrons released during nuclear fission, helping the nuclear fission chain reaction to occur more effectively. Water, graphite, etc. are used.
- Control rod: Made of neutron-absorbing material (cadmium, boron, etc.), it controls the speed of the nuclear fission chain reaction and, in an emergency, stops the reactor.
- Steam Generator: A device that boils water using the heat generated in the reactor to create high-temperature, high-pressure steam.
- Turbine: A machine that rotates using the power of steam generated in a steam generator.
- Generator: A device that converts the rotational energy of a turbine into electrical energy.
- Condenser: A device that cools the steam produced by turning the turbine and condenses it back into water. Cooling is usually done using seawater or a cooling tower.
- Coolant: A substance that transfers the heat generated by nuclear fission inside the reactor to the steam generator. Water is usually used.
- Containment Building: A sturdy concrete structure that prevents radioactive material from leaking outside.
3. Pros and Cons of Nuclear Power
merit:
- High energy efficiency: A small amount of nuclear fuel can produce a large amount of electricity. 1 gram of uranium can produce energy equivalent to about 1,800 liters of oil or about 3 tons of coal.

4. Safety of nuclear power generation
Nuclear power plants are working to ensure safety by building multiple protection systems.
- Defense in depth concept: Applying multi-level safety measures to prevent accidents from occurring and minimize their impact if they do occur.
- Multi-layer barriers: Multiple layers of barriers are installed around the nuclear fuel, fuel cladding, reactor vessel, and containment vessel to prevent radioactive materials from leaking outside.
- Emergency Cooling System: Equipped with a system to prevent overheating of the reactor and cool the nuclear fuel in the event of an accident.
- Earthquake-resistant design: Domestic nuclear power plants are designed to withstand strong earthquakes, and safety is continuously being strengthened.
- Strict safety regulations and management: Regulatory agencies, including the Nuclear Safety and Security Commission, enforce strict safety standards and manage and supervise power plants.
