Nuclear reactions create thermal energy, which is used to make steam driving a turbine-generator, producing electricity

The ability to do work, or the amount of fuel contained within something.

The rate at which work is done or amount of energy flow per unit time.

Processes that generate thermal energy used in nuclear power plants.

Major issues of concern related safety and security in nuclear power, requiring careful handling and management.

A unit of energy; equal to 1 kg-m²/s².

A unit of power; equal to 1 Joule/second.

A unit of energy equal to 3.6 million Joules (3.6 x 10⁶ Joules).

Energy cannot be created or destroyed, only transformed from one form to another.

Stored energy that an object has due to its position or condition.

Energy an object possesses due to its motion.

Electricity generated from the kinetic energy of moving water, often using dams to create a reservoir and control water flow.

Electricity generated from the kinetic energy of wind, using wind turbines to convert wind energy into mechanical energy.

Electricity generated directly from sunlight using solar panels, which convert light energy into electrical energy.

A system that uses mirrors to concentrate sunlight onto a receiver, heating a fluid to generate steam and drive a turbine for electricity production.

A large mirror that tracks the sun's movement, reflecting sunlight towards a central receiver in a Concentrating Solar Power plant.

A type of heat transfer fluid used in Concentrating Solar Power plants, heated by concentrated sunlight to store thermal energy.

A storage container for molten salt in Concentrating Solar Power plants, used to store the molten salt at lower temperatures.

A storage container for molten salt in Concentrating Solar Power plants, used to store the molten salt after it is heated by concentrated sunlight.

Molten salt is used as a heat transfer fluid in solar power plants. It absorbs solar energy, transferring it to a steam turbine to generate electricity.

The Rankine cycle is a thermodynamic process converting heat into mechanical energy, which then powers a generator for electricity.

The substance used within a closed loop in the Rankine cycle to transfer and convert heat into mechanical energy.

The state of the working fluid after being heated in a boiler in the Rankine cycle, where it's fully vaporized and ready to drive the turbine.

A device in the Rankine cycle that converts the kinetic energy of the expanding vapor into rotational mechanical energy.

Electricity that is continuously supplied, regardless of fluctuations in demand, such as from nuclear or fossil fuels.

Renewable energy sources for electricity generation, but not suitable for continuous baseload power due to intermittent nature.

A renewable energy source that generates electricity from the flow of water, but with limited growth potential.

The ratio of the net work output of a system to the heat added to the system. It represents how effectively a system converts heat energy into useful work.

An idealized thermodynamic cycle with the maximum possible efficiency for a given temperature difference. It serves as a benchmark for real-world power cycles.

Fossil fuel plants use the combustion of fuel like coal to generate heat, while nuclear plants use nuclear fission reactions to produce heat.
