- Some heavy nuclei, containing even more protons than the uranium nucleus undergo “spontaneous fission,” splitting apart without absorbing a neutron. Why is spontaneous fission observed only in the heaviest nuclei?Consider the fission reaction see image After having found the missing nuclide, calculate the Q-value of the reaction. Enter your result in MeV to 1 decimal placeConsider two heavy nuclei X and Y having similar mass numbers. If X has the higher binding energy, which nucleus tends to be more unstable?
- Find question in Image.A large power reactor that has been in operation for some months is turned off, but residual activity in the core still produces 150 MW of power. If the average energy per decay of the fission products is 0.96 MeV, what is the core activity in units of curies?Ordinary hydrogen is sometimes called a perfect fuel, both because of its almost unlimited supply on Earth and because, when it burns, harmless water is the product of the combustion. So why don’t we abandon fission and fusion energies, not to mention fossil-fuel energy, and just use hydrogen?
