Which of the following is a best nuclear fuel?

  • A. Thorium 236
  • B. Plutonium 239
  • C. Uranium 236
  • D. Neptunium 239

Step-by-step solution

Among the options, Plutonium-239 is a fissile isotope that can sustain a nuclear chain reaction, making it an excellent nuclear fuel. Thorium-236 is not a common isotope and is not fissile; Uranium-236 is not fissile and is typically a byproduct; Neptunium-239 is a precursor to Plutonium-239 and not directly used as fuel.
