Assume That (I)the Energy Released Per Fission Event of ²³⁵U

Assume that (i) the energy released per fission event of ²³⁵U is 194 MeV,and (ii) 33% of the nuclear energy released in a power plant is ultimately converted to usable electrical energy.Approximately how many fission events will occur in one second in order to provide the two-GW electrical power output of a typical power plant? (1 eV = 1.6 × 10−¹⁹ J)

A) 4E+23 fission/s
B) 2E+20 fission/s
C) 6E+25 fission/s
D) 2E+15 fission/s
E) ​8E+17 fission/s
