A laser-fusion fuel pellet has mass 1.0 mg and consists of equal parts (by mass) of deuterium and tritium.
(a) If half the deuterons and an equal number of tritons participate in D-T fusion, how much energy is released?
(b) At what rate must pellets be fused in a power plant with 3000-MW thermal power output?
(c) What mass of fuel would be needed to run the plant for 1 year? Compare your answer with the 3.6x106 tons of coal needed to fuel a comparable coal-burning power plant.
