Thorium itself is not a fuel, it does not emit energy. However if it is irradiated in a reactor it forms uranium233 which is a fissile isotope of uranium. Therefore potentially thorium can be used to breed fissile fuel. There are issues around reprocessing however which have not been tackled because the incentive is not there whilst uranium235 is available. Thorium might become important in the future, or for a country which has thorium but not uranium.

Which all radioactive elements are used for nuclear reactors in India?
India primarily uses uranium and thorium as radioactive elements for its nuclear reactors. Uranium is the primary fuel for Pressurized Heavy Water Reactors (PHWRs), while thorium is used in some reactors as a fertile material for breeding fissile uranium-233.
Nuclear power without Uranium?
One alternative to uranium in nuclear power is thorium. Thorium can be used as a fuel in advanced nuclear reactors, offering potential benefits such as increased safety and reduced nuclear waste. Research and development are ongoing to explore the viability of thorium-based nuclear power.
Breeder reactors are used to convert?
Breeder reactors are used to convert non-fissile isotopes (such as U-238) into fissile isotopes (such as Pu-239) through neutron capture reactions, thereby producing additional fuel for nuclear reactors while generating energy. This process allows for the sustainable use of nuclear energy by recycling and reusing nuclear fuel.
How does the uranium used in a CANDU reactor exist in nature?
The uranium used in a CANDU reactor primarily exists as uranium-238, a naturally occurring isotope found in various minerals, with a small percentage of uranium-235. It is extracted from uranium ore through milling and chemical processes to increase the concentration of uranium-235 for use as nuclear fuel in reactors.
Does CANDU reactor use enriched uranium?
CANDU Reactors are specifically designed such that they do not require enriched uranium, and can operate entirely on naturally-occurring uranium. A CANDU design is generally used by parties that do not desire uranium enrichment facilities, due to the cost of those facilities. That said, a CANDU reactor CAN use enriched uranium, they are fully capable of supporting that fuel type.
What is the naturally occurring actinide that is used in nuclear reactors?
We look to the naturally occurring element uranium as a nuclear fuel.
Which country has thorium reserves?
India has the largest reserves of thorium in the world, followed by countries like Australia and the United States. Thorium is a naturally occurring radioactive element that can be used as a fuel in nuclear reactors.
Explain thorium as a type of radiation source?
Thorium is a naturally occurring radioactive element that can be used as a fuel in nuclear reactors. It undergoes a process of radioactive decay, emitting alpha particles that can be harnessed for energy production. Thorium-based nuclear reactors have the potential to be safer, more efficient, and produce less long-lived radioactive waste compared to conventional uranium-based reactors.
What does Uranium and Thorium have in common?
Uranium and thorium are both metals in the actinoid series of the periodic table. They are both silvery colored, both softer than steel, somewhat ductile, and not very good conductors of electricity. They are somewhat similar chemically. Uranium and thorium are both naturally occurring radioactive substances. In fact they are the only radioactive substances occurring in any abundance on earth. Neither is very commonly found, but thorium is much more common on land in minerals and ores. They can both be used for fuel in nuclear reactors, though the reactors designed for them are differently designed so as to take advantage of them most efficiently. Uranium differs from thorium in one major way, which is that it has a fissile isotope. In fact, Uranium-235 is the only fissile isotope occurring in nature. The fact that it is fissile means that it will naturally undergo fission spontaneously. Other naturally occurring isotopes of both uranium and thorium are fissionable, meaning that it can be induced to undergo fission by colliding a neutron into its nucleus.
Fuel for nucleur reactors?
Uranium, plutonium or thorium (for fission reactors, by far the most common type).
Is thorium used in nuclear reactors?
Not as fuel, but it can be used in breeder reactors as breeding material to make fissile Uranium-233.
Why thorium is not used as fuel in nuclear reactors?
Thorium is and can be used as a fuel in nuclear reactors. It just happens to be not fissile, so it needs a neutron flux to create Uranium-233, which is fissile. There are pros and cons of using Thorium. For more information, please see the Related Link below.
What naturally occurring radioistope is used as the fuel for a nuclear reactor?
Uranium is usually the element of choice for nuclear fuel. We also like to recover the uranium-235 isotope for fuel if we can. Some reactors use mostly U-235 for fuel, and some use a bit of U-235 in with U-238 for fuel.
What other element can thorium be combined with to create a new product?
Thorium can be combined with uranium to create nuclear fuel used in certain types of nuclear reactors, such as thorium-based reactors. This combination can enhance the sustainability and safety of nuclear power generation.
What is the element named after Thor the God of War?
The element named after Thor, the God of War, is thorium. It is a silvery metal that is named after the Norse god due to its strength and stability. Thorium is used in nuclear reactors as a fuel source.
If uranium was to run out what other sources are available to replace it?
AnswerProbably the nuclear fusion AnswerThere are a number of reactor designs based on using thorium, and fuel assemblies using thorium as a primary fuel can be designed and built to be used in existing reactors.
Which all radioactive elements are used for nuclear reactors in India?
India primarily uses uranium and thorium as radioactive elements for its nuclear reactors. Uranium is the primary fuel for Pressurized Heavy Water Reactors (PHWRs), while thorium is used in some reactors as a fertile material for breeding fissile uranium-233.
