Answer:
The number of reaction that must occur is 6.142 x 10¹⁸ reactions / second
Explanation:
Given;
energy released by the fission reaction, E = 173 MeV
power output, P = 170 MW
Convert the energy released by the fission reaction to Joules;
= 173 x 10⁶ x 1.6 x 10⁻¹⁹ J = 2.768 x 10⁻¹¹ J
Convert the output power to joules per second;
= 170 x 10⁶ J/s
The number of reactions per second that must occur is given by;
[tex]= \frac{170*10^6 \ J/s}{2.768*10^{-11} J/reaction} = 6.142 *10^{18} \ reaction/second[/tex]
Therefore, the number of reaction that must occur is 6.142 x 10¹⁸ reactions / second
