The Science of Nuclear Power. Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. The nuclear energy harnessed around the …

The reactor is controlled by control rods housed in a cross-shaped, or cruciform, arrangement called a control element. The control elements enter from the bottom of the reactor and move in spaces between the fuel assemblies. The BWR reactor core is housed in a pressure vessel that is larger than that of a PWR.

Through cables, power is transferred from the generator to a nearby transformer. Step-up transformer: While moving through wires, electricity loses part of its power; high-voltage electricity does so at a lower rate than low-voltage energy. As a result, the voltage of the electricity is "stepped up" or "boosted" as it exits the power plant.

A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

The magical science of power plants. A single large power plant can generate enough electricity (about 2 gigawatts, 2,000 megawatts, or 2,000,000,000 watts) to supply a couple of hundred thousand homes, and that's the same amount of power you could make with about 1000 large wind turbines working flat out. But the splendid …

A nuclear power plant is a promising emission-free and reliable source of electricity. By its principle, it belongs to the group of thermal power plants, in which an electric generator is driven by a turbine turned by the energy of flowing hot steam. The only difference, compared to fossil fuel power plants, is the heat source that creates this ...

The pressurized water reactor (PWR) works in 4 steps: The reactor core within the reactor vessel generates heat through fission reactions. The high-pressure water from the primary circuit transports this thermal energy to a steam generator outside the pressure vessel. Inside the steam generator, the heat coming from the primary circuit …

A nuclear reactor consists of fuel rods, control rods and moderator. A fuel rod contains small round fuel pallets (uranium pallets). Control rods are of cadmium which absorb neutrons. They are inserted into reactor and can be moved in or out to control the reaction. The moderator can be graphite rods or the coolant itself.

How Gas Turbine Power Plants Work. The combustion (gas) turbines being installed in many of today's natural-gas-fueled power plants are complex machines, but they basically involve three main sections: The compressor, which draws air into the engine, pressurizes it, and feeds it to the combustion chamber at speeds of hundreds of miles per hour.
