Let's say a nuclear power plant in India produces 100 cubic meters of high-level nuclear waste over 5 years. This waste is extremely hot and radioactive. How do we manage it?

1. **Initial Cooling:** First, the waste is put into large water pools for several years. This is like letting a very hot tawa cool down after making rotis. It reduces heat and some radioactivity.
2. **Reprocessing (Optional):** Some countries reprocess the waste to extract usable fuel. Let's say 95 cubic meters are still highly radioactive after this.
3. **Solidification:** The remaining 95 cubic meters of liquid waste are mixed with glass-forming materials and heated to a very high temperature. This turns it into a stable, solid glass form, making it less likely to leak.
4. **Encapsulation:** These solid glass blocks are then sealed inside sturdy metal canisters, like putting precious items in strong, airtight containers.
5. **Interim Storage:** The canisters are stored in secure, above-ground facilities, often for decades, while a permanent disposal site is prepared. This is like keeping important documents in a safe locker.
6. **Geological Disposal:** Finally, these sealed canisters will be buried deep underground, often hundreds of meters below the surface, in stable rock formations. This is the long-term solution, ensuring the waste is isolated from humans and the environment for thousands of years.

Answer: Nuclear waste is managed through a multi-step process involving cooling, solidification, encapsulation, interim storage, and eventual deep geological disposal to ensure long-term safety.
