Briefly explain why it is so expensive to close down a nuclear power plant
What will be an ideal response
The materials in a nuclear power plant absorb radiation from the fuel, and when a plant is closed down it cannot simply be abandoned, but must go through a process called decommissioning. The old building parts and equipment are actually a form of radioactive waste and have to be treated as such. The plant can either be entombed or surrounded by a physical barrier. These options require security around the old plant for 30 to 100 years.
Another approach is to dismantle the plant and send all of the materials to a permanent nuclear waste storage facility (which to date has not been built in any country).
