Question: Energy released in the fission of a single 92U235 nucleus is 200 MeV. The fission rate of a 92U235 fuelled reactor operating at a power level of 5W is [CBSE PMT 1993]

Options:

A) 1.56×10+10s−1

B) 1.56×10+11s−1

C) 1.56×10+16s−1

D) 1.56×10+17s−1

Show Answer

Answer:

Correct Answer: B

Solution:

EnergyFission=200 MeV=200×106×1.6×10−19J

Fission rate =5200 MeV=1.56×1011 fission/sec.
