43 //! \brief Main program of the FissionFragment example
44 //!
45 //! \details Application demonstrating the Fission Fragment model as used
46 //! within the neutron_hp model. It demostrates the capability
47 //! for fission product containment by the cladding in a water
48 //! moderated sub-critical assembly.
49 //! It could also be further extended to calculate the effective
50 //! multiplication factor of the subcritical assembly for
51 //! various loading schemes.
