Question

Which statement is true?
Nuclear power plants require more fuel than conventional power plants.
There is a short supply of high quality uranium.
Nuclear power plants are inefficient.
It is difficult to responsibly dispose of nuclear waste products.

Answer 1

The true statement is: "It is difficult to responsibly dispose of nuclear waste products."

Brief explanations:
- Nuclear plants require far less fuel mass than fossil plants for the same energy output (so the first statement is false).
- There are commercially recoverable uranium resources sufficient for many decades at current consumption; high‑grade ore is limited but not currently in short supply in a way that prevents operation (so the second statement is misleading/false in general).
- Nuclear plants have thermal efficiencies similar to conventional steam plants (older thermal plants ~30–40%); they are not inherently inefficient (so the third statement is false).
- Long‑term management of radioactive waste (especially high‑level, long‑lived waste) is technically and politically challenging, making safe disposal difficult in practice.
