Commercial power generation from fusion reactor is not yet possible, because___________________?
Correct answer: A. It is difficult to control nuclear fusion reaction
- A. It is difficult to control nuclear fusion reaction
- B. The fuel required (i.e., deuterium & tritium) is scarce
- C. It is difficult to initiate fusion reaction
- D. Quantity of fuel required for initiating fusion reaction is prohibitively high
Explanation
Fusion requires an extremely hot plasma and must be initiated and maintained without losing control through instabilities and energy losses. Deuterium is abundant and tritium can be bred, so fuel scarcity is not the main obstacle.
