Fission | Physics


Fission is the opposite of fusion and releases energy only when heavy nuclei are split. ... The amount of energy per fission reaction can be large, even by nuclear standards. ... about 1 MeV per nucleon, or approximately 240 MeV per fission, is released. ... given the atomic masses to be m(238U) = 238.050784 u, m(95Sr) ...

Given that

The amount of electricity that will be generated E = 200000 MW

Nuclear power plants are needed to provide the energy = 10% of E  

= \frac{10}{100} * 200000 = 20000 MW   

= 20000 * 10^{6} joules/sec

Nuclear power per year (Converting joules/sec to joules/year)

= 2 * 10^{10} * 365*24*60*60 = 6.307*10^{17}  joules/year

The energy emitted by a single uranium nucleus fission is 200 MeV.

Per fusion, the amount of nuclear energy converted into electrical energy = 25 % of 200 MeV  

\frac{25}{100} * 200 = 50 MeV = 50 * 10^{6} * 1.6* 10^{-19} = 8* 10^{-12} Joules


Step 1: Determining the number of atoms required to per fission per year

[math]

number of fissions per year = \frac{6.307*10^{17}}{8* 10^{-12}} = 78840* 10^{24} atoms  


Step 2: Finding the mass of nuclear substance per year

  

1 g (1 mole) of the uranium contains 6.023* 10^{23} atoms

Atomic mass of uranium =  235 g = 235* 10^{-3} Kg

Mass of 78840* 10^{24} uranium atoms = \frac{235* 10^{-3}}{6.023* 10^{23}} * 78840* 10^{24}

= 3.016 * 10^{4} kg

As a results, the amount of uranium required each year   = 3.016 * 10^{4} kg
