how does a nuclear power plant produce energy

thanks again Ms Sue
You're welcome, Laila.
This page says it's under construction, is there another page to check an answer for this?
My answer was b. Through nuclear fission reaction
A nuclear power plant generates electricity through a process called nuclear fission, which involves splitting atoms of heavy elements, typically uranium or plutonium. Here's a step-by-step explanation of how a nuclear power plant produces energy:
1. Fuel: The first step is to obtain the nuclear fuel, usually in the form of uranium-235. Uranium atoms are chosen because they are fissile, meaning they can easily split when hit by a neutron.
2. Fission: The nuclear reactor inside the power plant has fuel rods, which are bundles of fuel pellets containing uranium. When a neutron collides with a uranium-235 atom, it can cause it to become unstable and split into two smaller atoms, releasing a large amount of energy in the process. This is known as fission.
3. Heat Generation: The energy released during fission appears as heat. The heat generated by the chain reaction of fission is used to produce steam.
4. Steam Generation: The heat is used to boil water and create high-pressure steam. This is achieved by circulating the hot coolant from the reactor core through a heat exchanger called a steam generator.
5. Steam Turbine: The high-pressure steam then flows through pipes to a steam turbine. The steam enters the turbine, causing its blades to spin rapidly.
6. Electricity Generation: The spinning turbine is connected to a generator, where a shaft inside the generator is turned by the turbine. This rotating shaft generates electricity through the phenomenon of electromagnetic induction.
7. Transmission and Distribution: The electricity produced in the generator is sent to a transformer, which increases the voltage for efficient transmission over long distances through power lines. Transformers then step-down the voltage to usable levels for homes, businesses, and industries.
8. Cooling: After passing through the turbine, the now low-pressure steam is condensed back into water by a condenser, using cool water from a nearby source (such as a river or ocean). The cooled water is then returned to the steam generator to be reheated and converted back into steam.
9. Control and Safety: Nuclear power plants have various control mechanisms and safety measures in place to regulate the nuclear reactions, monitor coolant flow, and prevent overheating or other accidents. These include control rods, which absorb neutrons and control the pace of the chain reaction, and multiple redundant safety systems to ensure the plant operates safely.
It's worth noting that nuclear power plants produce a significant amount of energy from a relatively small amount of fuel. The resulting electricity is generally reliable and produces low greenhouse gas emissions, but it also brings concerns regarding waste management, safety, and proper plant decommissioning.
