When nuclear power plants reach the end of their useful life, they must be decommissioned. It is estimated that 285 of the world's 437 nuclear reactors will need to be decommissioned by 2025. Discuss the options for this process.

What will be an ideal response?


There are three ways to dismantle and safely store high level radioactive materials from nuclear power plants. One is to store in a permanent secure repository. The second is to install a physical barrier around the plant and employ a full time security detail for 30 to 100 years until it can be safely dismantled. The third is to enclose the entire plant in a concrete and steel tomb or containment structure.
