What are the three types of radioactive waste? |
High Level Intermediate Level Low Level |
|
|
|
What are examples of high level radioactive waste? |
Fuel element cladding Sludge from treatment process Containers of radioactive matetials |
|
|
|
How is high level radioactive waste dealt with? |
Used reactor fuel rods stored in cooling ponds within station so short term radioactivity dies away
Encased in steel containers at processing plant
Kept under water
Cladding removed
Unused uranium and plutonium from fuel rods kept in sealed containers
Waste converted into powder, fused into glass blocks sealed in air cooled containers for 50 years Stored deep underground in stable rock formation
Stored deep underground in stable rock formation |
7 steps Cooling pond Encased Under water Cladding Unused isotopes Powder Glass 50 years Underground |
|
|
How long does high and intermediate level waste remain deadly for? |
Thousands of years |
|
|
|
Examples of intermediate level radioactive waste |
Fuel element cladding Hospital radioisotopes |
|
|
|
How is intermediate level radioactive waste dealt with? |
Stored in steel drums encased in concrete Stored in reinforced concrete buildings or deep underground in a stable rock formation with low water flow |
|
|
|
Examples of low level radioactive |
Lab equipment Protective clothing Cooling pond water |
|
|
|
How is low level radioactive waste dealt with? |
Sealed in metal drums buried deep underground Treated cooling pond water released to environment |
|
|
|
How long does low level radioactive waste remain dangerous for? |
Few months to a year |
|
|
|
What are the main source of dangerous waste? |
The highly radioactive fission fragments from the fission of uranium 235
Spent fuel rods |
