At this time‚ many people have been aware about advantages of nuclear power that can mitigate global warming impact but they don’t notice the disadvantages of nuclear power. The advantages of nuclear power are the emission of green house is relatively low‚ this technology is readily available‚ it can produce high amount of electrical energy. Whereas the disadvantage are the problem of radioactive waste‚ high risk‚ not renewable energy‚ not sustainable energy‚ etc. From the above explanation‚ nuclear
