Question: Imagine that a reactor converts all given mass into energy and that it operates at a power level of 109 watt. The mass of the fuel consumed per hour in the reactor will be : (velocity of light, c is 3×108m/s )

Options:

A) 0.96gm

B) 0.8gm,

C) 4×102gm     

D) 6.6×105gm

Show Answer

Answer:

Correct Answer: C

Solution:

  • Power level of reactor, P=EΔt=Δmc2Δt mass of the fuel consumed per hour in the reactor, ΔmΔt=Pc2=109(3×108)2kg/sec=3600×1099×1016 ×103gmhr
