As noted in Fusion, energy is released if the products of a nuclear reaction have a greater binding energy per nucleon (BE/A) than the parent nuclei.Figure 2 shows that BE/A is greater for medium-mass nuclei than heavy nuclei, implying that when a heavy nucleus is split, the products have less mass per.

Najmedin Meshkati, The Conversation, 26 Aug. 2022 These differ from the RBMK reactors at Chernobyl, which used graphite instead of water to sustain the fission reaction. Lauren Michele Jackson, The New Yorker, 12 Sep. Recent Examples on the Web: Noun Serpell discloses the dynamics of this once nuclear family by means of fission.
