In a liquid metal fast breeder reactor, the type of uranium used is:
Correct answer: B. 92U238
- A. 92U235
- B. 92U238
- C. 92U234
- D. 92U239
Explanation
In a fast breeder reactor, 92U238 is used as fuel. The 92U238 isotope can undergo neutron capture and become U239, which further undergoes beta decay to form Np-239, and then Pu-239. This process is part of the breeder reactor cycle.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
