What is the back end of the nuclear fuel cycle?
The back end of the nuclear fuel cycle involves managing the spent fuel after irradiation. For Synatom, this entails all the steps between draining the nuclear units’ spent fuel pools and final storage.
What are the parts of the nuclear fuel cycle?
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 does the nuclear fuel cycle represent?
The nuclear fuel cycle represents the progression of nuclear fuel from creation to disposal. In the United States, uranium is processed in different chemical and physical forms to create nuclear fuel.
What is a fuel pin in a nuclear reactor?
The fuel in a reactor – typically uranium – is placed into long metal tubes, which are sealed and then placed in a reactor. These fuel “pins” undergo nuclear fission, where atoms split apart and release heat that produces electricity. Once the fuel is used up, it is removed from the reactor.
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.
What is uranium’s family?
From a chemical point of view, uranium belongs to the actinide family, a group of atoms whose properties are similar to those of actinium, the 89th element in Mendeleyev’s periodic table. Uranium can be found in the Earth crust at 3 parts per million, particularly in granite and volcanic rocks.
What is front end fuel cycle?
The front-end of the nuclear fuel cycle has four stages: mining and milling, conversion, enrichment, and fabrication. Mining and milling is the process of removing uranium ore from the earth, and physically and chemically processing the ore to develop “yellow-cake” uranium concentrate.
Which of the following steps make up the front end of the nuclear fuel cycle?
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 are the 4 types of nuclear reactors?
Main types of nuclear reactor
- Pressurised water reactor (PWR)
- Boiling water reactor (BWR)
- Advanced gas-cooled reactor (AGR)
- Light water graphite-moderated reactor (LWGR)
- Fast neutron reactor (FNR)
- Operable nuclear power plants.
Who named uranium?
Martin Heinrich Klaproth
Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten….

Who discovered uranium-235?
Arthur Jeffrey Dempster
Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about 584.3±1 barns. For fast neutrons it is on the order of 1 barn.
