Q. What is/are the advantage of nuclear fusion?
1.Produce more energy than coal, oil, gas or nuclear fission
2.High chance of meltdown
3.Do not emit harmful toxins like CO2 or other greenhouse gases
Select the correct answer from the codes given below:
Statement 1 is correct: Gram for gram, thermonuclear power produces four million times more energy than burning coal. A kilogram of fusion fuel contains about 10 million times as much energy as a kilogram of coal, oil or gas e.g., if four grams of hydrogen can be fused into helium, it can light a 60-watt light bulb for over 100 years.
Fusion reactors produce four times more energy than nuclear fission reactions.
Statement 2 is incorrect: Any disturbance/malfunction will lead to the cooldown of plasma within seconds and the fusion reaction stops. Hence, they have a low risk of meltdown.
Statement 3 is correct: Nuclear fusion does not emit harmful toxins like CO2 or other greenhouse gases. The only waste product from nuclear fusion is the harmless helium which is an inert and non-toxic gas.
