Commonly used nuclear fuels

Nuclear fuels are substances that can sustain a nuclear reaction. Commonly used nuclear fuels include:

- U235: Uranium-235 is a naturally occurring isotope of uranium and is commonly used as a nuclear fuel in nuclear reactors.

- Pu239: Plutonium-239 is a man-made isotope of plutonium and is also widely used as a nuclear fuel in reactors.

Both U235 and Pu239 are commonly used in nuclear reactors for power generation due to their ability to undergo fission reactions efficiently.

Incorrect options:

- U238: Uranium-238 is another isotope of uranium, but it is not commonly used as a nuclear fuel because it is not fissile, meaning it cannot sustain a nuclear chain reaction on its own.

- Pu243: Plutonium-243 is not commonly used as a nuclear fuel. The most commonly used isotopes of plutonium in nuclear reactors are Pu239 and Pu240.

Therefore, the correct options for commonly used nuclear fuels are U235 and Pu239.
