You are designing the fuel requirements for a small fusion electric-generating plant. Assume 30% conversion to electric energy. For the deuterium-tritium (D-T) fusion reaction, calculate the number of reactions per second that are necessary to generate 1.20 kW of electric power. (The energy released per reaction is 17.59 MeV.)

answer in _____reactions/second

Solution

Power P = n/t(30%E)

n/t = P/30%E

= 1.20*10^{3 *} 100 /30*17.59*10⁶*1.6*10^-19

= 1.20 / 84.432*10^-17

n/t = 1.42*10¹⁵ reactins / sec
