Question

A nuclear reactor has a power of $16KW$.If the energy per fission is $200MeV$, the number of fissions per second is

• A. 5 x 10${}^{16}$
• B. 5 x 10${}^{17}$
• C. 5 x 10${}^{14}$
• D. 5 x 10${}^{15}$

Answer 1

The correct option is C 5 x 10${}^{14}$

Power of nuclear reactor $=16KW$
Energy per fission $=200MeV$
No of fissions per second $=\frac{16\times {10}^3}{200\times {10}^6\times 1.6\times {10}^{-19}}$

$=5\times {10}^{14}$ nuclear fission reaction per seconds
