(a) How much mass is lost per day by a nuclear reactor operated at a `10^9` watt power level?
(b) If each fission releases 200 MeV, how many fissions occur per second to yield this power level?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
(a) `m(c)^2=pxxt`
`:.` `m=(pxxt)/(c^2)`
`=((10^9)(24)(3600))/(3xx10^8)^2`
`=9.6xx10^-4kg`
(b) Number of fissions required per second
=Energy required per second/Energy released in one fission
`=(10^9)/(200xx10^6xx1.6xx10^-19)`
`=3.125xx10^19`
