With the reprocessing of used fuel as an option for nuclear energy, the stages form a true cycle. To prepare uranium for use in a nuclear reactor, it undergoes the steps of mining and milling, conversion, enrichment and fuel fabrication. These steps make up the ‘front end’ of the nuclear fuel cycle.
What steps produce electricity from uranium?
Once an atom of 235U is split, neutrons from the uranium atom collide with other atoms of the 235U. A chain reaction begins that produces heat. This heat is used to heat water and turn it into steam. The steam is used to drive a turbine connected to a generator that produces electricity.
What are the different steps needed to produce the fuel in nuclear power plants?
The nuclear fuel cycle consists of several steps: mining, milling, conversion, enrichment, fuel fabrication and electricity generation. The front end of the nuclear fuel cycle produces nuclear fuel for electricity generation.
What are the energy stages of the nuclear power production?
As illustrated below, the nuclear fuel cycle typically includes the following stages:
- Uranium recovery to extract (or mine) uranium ore, and concentrate (or mill) the ore to produce a uranium ore concentrate, sometimes called U3O8 or “yellowcake”
- Conversion of uranium ore concentrate into uranium hexafluoride (UF6)
What are four main stages of nuclear power station?

How much uranium is needed to power a city?
In the previous page we saw that with one tonne of either uranium or thorium, we can produce a gigawatt year of electricity (1GWye), the amount you’ll need to power a modern city with a million inhabitants for a year.
Where is natural uranium found?
The mining of uranium
Uranium is found in small amounts in most rocks, and even in seawater. Uranium mines operate in many countries, but more than 85% of uranium is produced in six countries: Kazakhstan, Canada, Australia, Namibia, Niger, and Russia.
How much electricity can 1 gram of uranium produce?
The fission of 1 g of uranium or plutonium per day liberates about 1 MW. This is the energy equivalent of 3 tons of coal or about 600 gallons of fuel oil per day, which when burned produces approximately 1/4 tonne of carbon dioxide. (A tonne, or metric ton, is 1000 kg.)
What are the 2 types of nuclear power plants?
U.S. nuclear power plants use two types of nuclear reactors
Nuclear power plants in the United States have either a boiling-water reactor or a pressurized-water reactor.
Is the way that nuclear waste is categorized is different in various countries?
In most other countries, nuclear waste is categorized as low level waste, intermediate level waste, and high level waste.
How long do nuclear rods last?
To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that uranium fuel up.
How long does nuclear energy last?
If the Nuclear Energy Agency (NEA) has accurately estimated the planet’s economically accessible uranium resources, reactors could run more than 200 years at current rates of consumption.
Where does nuclear waste go?
Low-level radioactive waste is collected and transported safely to one of four disposal facilities in South Carolina, Washington, Utah or Texas. Some low-level waste can be stored at the plant until its stops being radioactive and is safe to be disposed of like normal trash.
