How is the fission of `_92^235U` nucleus brought about?

Suppose, we think of fission of a "_26^56Fe nucleus into two equal fragments, "_13^28Al . Is the fission energetically possible? Argue by working out Q of the process. Given m ( "_26^56Fe ) = 55.93494 u and m ( "_13^28Al ) = 27.98191 u.

Consider the fission of "_92^238U by fast neutrons. In one fission event, no neutrons are emitted and the final end products, after the beta decay of the primary fragments, are "_58^140Ce and "_44^99Ru . Calculate Q for this fission process. The relevant atomic and particle masses are m( "_92^238U ) =238.05079 u m( "_58^140Ce ) =139.90543 u m( "_44^99Ru ) = 98.90594 u

Nitrogen fixation in root nodules of Alnus is brought about by :

A 1000 MW fission reactor consumes half of its fuel in 5.00 y. Howmuch "_92^235U did it contain initially? Assume that the reactor operates80% of the time, that all the energy generated arises from the fission of 23592 U and that this nuclide is consumed only by the fission process.

Suppose India had a target of producing by 2020 AD, 200,000 MW of electric power, ten percent of which was to be obtained from nuclear power plants. Suppose we are given that, on an average, the efficiency of utilization (i.e. conversion to electric energy) of thermal energy produced in a reactor was 25%. How much amount of fissionable uranium would our country need per year by 2020? Take the heat energy per fission of "^235U to be about 200MeV.

The volume occupied by an atom is greater than the volume of the nucleus by a factor of about:

Calculate the energy released by the fission of 1.0 kg of "^235U in a fission reactor.
