Nuclear Fission Lab
Fission product yields from isotope data, decay trees for any nuclide, and a WebGL chain-reaction animation.
About this tool
Nuclear Fission Lab reads nuclear-isotopes.json (all Z=1…118 with many A values). Curated nuclides use measured half-lives/branches; others use schematic valley-of-stability rules — see the file’s note. Not for licensing or dosimetry.
- Fission products — double-humped yields for U-235, Pu-239, …
- Decay tree — follow α/β/EC/IT/SF daughters
- Chain reaction — WebGL neutrons + fuel; tune k≈ν·p_fission
Complements Nuclear Decay Lab (Bateman chains / SEMF Q-values) and Half Life.
