Question

In a nuclear reactor 0.01 mg of a fissile material is totally converted into energy in one second. The power of a reactor in MW is

• A. 1000
• B. 900
• C. 0.01
• D. 100

Answer 1

The correct option is B 900

Using $E=m{c}^2$
$={10}^{-8}\times (3\times {10}^8{)}^2$
$=9\times {10}^{8}J$
E = 900 Mw
