Correct Statements about Uranium:
Majority of the naturally occurring uranium is of the isotope U-235:
- This statement is incorrect. The majority of naturally occurring uranium is actually the isotope U-238, which makes up about 99.3% of natural uranium. U-235 only makes up about 0.7% of natural uranium.
Naturally occurring uranium can be used in a weapon or in nuclear power plants to generate nuclear energy:
- This statement is correct. Uranium can be used for both peaceful purposes, such as generating nuclear energy in power plants, as well as for military purposes, such as in the production of nuclear weapons.
Uranium ore is enriched in order to increase the concentration of U-235:
- This statement is correct. Uranium ore must undergo an enrichment process to increase the concentration of U-235, which is necessary for nuclear reactions in power plants or weapons. The enrichment process separates U-235 from U-238, increasing the proportion of U-235 in the final product.
Therefore, out of the three statements provided, only the second and third statements are correct.

Only Statement 3 is correct.
- Approximately 99.3% of naturally occurring uranium is of the isotope U-238, which is not fissionable. Naturally occurring uranium, therefore, cannot be used in a weapon, or for that matter, in nuclear power plants.
- Thus, uranium ore is enriched in order to increase the concentration of U-235. Most nuclear power plants require an enrichment of 3-4% U-235 to sustain a chain reaction. Fission bombs on the other hand need closer to 90% enrichment.
