Overview
Answer the following questions concerning the nuclear power generation.
1) In the reprocessing of nuclear fuels used in the nuclear power generation, how are the volatile elements such as lodine recovered to prevent the discharge to the environment? Describe briefly the recovery method of volatilized iodine.
2) In the reprocessing of the high-level radioactive wastes, glasses called as borosilicate glasses, which
contain boron and silicon oxides, are used. What is the reason why the borosilicate glasses are used?
Describe the two properties of borosilicate glasses which are suitable for the reprocessing of radioactive wastes.
3) Immobilization of volatile radioactive elements by using the borosilicate glasses is quite difficult.
Describe the reason.
