Nuclear waste management
What is radioactive waste?
The nuclear waste is the material that was used in nuclear reactors, or those objects like protective clothing or tools that was in direct contact with the radiating material, or contaminated with excess radiation.

There are two types of this waste: High Level Waste (HLW) and Low Level Waste (LLW), categorized by the level of their radiation.

How do we store radioactive waste?
LLW can be stored in special containers, the HLW is buried under the ground.

Hungarian radioactive waste storage
In the past the Hungarian radioactive waste was sent to Russia, but the contract ended in 2005.

Why is it so dangerous?
Such waste is dangerous because they emit ionized radiation, so killing or damaging cells, producing mutations and birth defects and also cause cancer.

Researchers had many plans for storage because the waste can’t be fully elided:

-Deliver to the space
-Sink into the oceans
-Bury deep into the ground

Risks to radioactive waste storage
-Design failures

After that, our radioactive waste was stored at Paks, near to the Hungarian nuclear power plant.

Since 2012 a new HLW storage facility was opened at Bátaapát, providing a more safe storage.

Nuclear Waste in data
In the OECD countries: 81000 m3 is produced per year

 A typical reactor generates about 27 tonnes of used fuel

In countries with nuclear power, radioactive wastes comprise less than 1% of total industrial toxic wastes.
But it increases.
We can store the used, or spent fuel rods by
two ways:
-wet storage (under water in power plants)
-dry cask storage (stored above ground in
canisters of steel)

Thanks for the attention!
