The objective is to separate fission products so that the hazard decay of the packages follows the green curve in Figure 3 (instead of the red curve for spent fuel itself). ... green point wellness linthicum mdNuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays. The two smaller nuclei are the fission products.
