Question

5. A nuclear power plant produces an average of 2.10 x 103 MW of power during a year of operation. Find the corresponding change in mass of reactor tuel, assuming all of the energy released by the uel can be converted directly to electrical energy, in a pracnea reactor, on a reative sına acaon the energy can be converted to electricity.) kg

Answer 1

Solution)

We know,

Energy produced = power*time

So, E= 2.1*10^3*10^6*365*86400 J =6.622*10^16 J

We also know,

E = mc^2

6.622*10^16 = m*9*10^16

Hence, mass, m = 0.735 kg
