Uranium is a silvery-gray metallic weakly radioactive chemical element has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U (99.27%) and 235 U (0.72%). All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). Uranium, thorium, and potassium are the ...READ MORE
Tremor is currently outdated and being reworked, and as far I know doesn''t work well with Calamity. Thorium is an excellent "first mod" if you don''t want to install too many new things in a single playthrough - it''s a fine mod. I''ve heard good things about Spirit, and seen a couple of playthroughs with it implemented, but have yet to try it myself.READ MORE
· The thorium fuel cycle therefore relies on the supply of neutrons from another source to produce the fissile material, which in practice means fission neutrons from U-235 or Pu-239. This is also the reason that the uranium fuel cycle had to be established first. Several thorium reactors have been tried in the past but all found to be uncommercial.READ MORE
