Cell: Structure and Functions
A fission reactor consumes half of its fuel in . How much did it contain initially? Assume that the reactor operates of the time, that all the energy generated arises from the fission of and that this nuclide is consumed only by the fission process.
Solution: The half life of the fuel is
we know that the energy produced in fission of Uranium is .
So, energy produced by 1kg of Uranium:
Since the reactor operate of time, so time of operation is .
The energy produced is:
The mass required for producing energy is:
Since this is the amount consumed and initial amount should have been double of this. So, the initial amount of Uranium would have been
