Problem associated with nuclear power plant is 

  1. Thermal pollution

  2. Emission of hazardous radio-nuclides

  3. Disposal of radioactive waste

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Some thermal power stations exchange 60 to 70% of their thermal energy by cycling with a body of water or by evaporating water through a cooling tower. 

This thermal efficiency creates more waste heat. Most commercial nuclear power plants release gaseous and liquid radiological effluents into the environment as a byproduct. 
The nuclear fission of uranium-235 produces large quantities of intermediate mass radioisotopes. The mass distribution of these radioisotopes peaks at about mass numbers 95 and 137 , and most of them are radioactive. The most dangerous for environmental release are cesium and strontium because of their intermediate half-lives and entry in the food chain.

Which of the following is the correct sequence of disposal of high-level radioactive wastes?
1. They are kept in thick leak proof containers
2. The wastes are concentrated to reduce their bulk
3. They are stored in special protective shields during handling and transport
4. The wastes are then buried deep down in the earth or undersea bed

  1. 2-1-3-4

  2. 3-2-1-4

  3. 3-1-2-4

  4. 2-3-1-4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Before disposal of high level of radioactive waste which is very harmful for living organism, there is procedure to dispose it. 

Radioactive waste is stored in special protective shield before handling and transport. After that it is reduce to minimum amount and kept in leak proof containers before depose it, so that it cant harm environment around. Waste should be dispose into deep down earth or under sea bed for misuse.
So, the correct option is '3-2-1-4'.
