The energy released per fission of uranium-235 is about 200 MeV. A reactor using U-235 as fuel is producing 1000 kilowatts power. The number of U-235 nuclei undergoing fission per second is, approximately-
A
106
B
2 × 108
C
3 × 1016
D
931
Answer
3 × 1016
Explanation
Solution
1 kW ≡ 3.1 × 1013 fission/sec
1000kW ≡ 3.1 × 1013 × 103 fission/sec
≡ 3.1 × 1016
