Homework Statement
What is the power output of a reactor fueled by uranium-235 if it takes 30 days to use up 10 Kg of fuel and if each fission gives 200 MeV of energy.
Homework Equations
The Attempt at a Solution
(I was absent that day so this answer is from someone else's notebook)
No of U-235 nuclei in 10 kg:
(6.023*10^23*10000)/235 = 2.56*10^25
Fission rate= (2.56*10^25)/(30*24*3600)= 9.76*10^18 J/s (?? how is it joules per second, isn't that number above just no. of nuclei?)
Therefore, energy produced through fission per second:
= 200* 9.76*10^18= 1.95*10^15 MW
So...is this correct?
Thank you
