Ex. 3. Learn the dialogues.
1. – What do you know about radioactive waste?
– It is very dangerous because of its radioactivity.
– What kind of isotopes does it consist of?
– It consists both of short- and long- lived isotopes. As for strontium and cesium they retain radioactivity for centuries.
2. – In what way is radioactive waste disposed of?
– It is stored in the water pool for some time.
– Why is it done?
– It is done to allow the short-lived isotopes to decay.
– And what happens then?
– Spent fuel rods are taken to a reprocessing plant, where the unburned fuel is recovered from them.
– What is it done for?
– The recovered fuel is reprocessed again.
3. – What are the main ways of waste burial?
– Well, first of all, the waste may be placed into glass blocks.
– What are the advantages of this method?
– These blocks are difficult to destroy and they do not release radioactivity, because the waste is blended into glass.
– And what happens to these blocks?
– They are permanently buried.
Ex. 4. Answer the following questions.
What is the most serious problem of nuclear power?
What constitutes the main bulk of nuclear waste?
What byproducts do spent fuel rods contain?
What are the ways of disposal of nuclear waste?
What does the potential hazard associated with nuclear waste arise from?
What requirements should the burial site meet?
Ex. 5. Speak about the problem of nuclear waste disposal.
