From what I saw, this mod seems not to be compatible with the Nuclear Science mod (https://mods.factorio.com/mod/atan-nuclear-science), because by loading the game with both enabled it crashes due to technologies having duplicate science packs, in this case "nuclear-science-pack". Removing either this or the other mod fixes it.
I think you can fix it if you rename this science pack to "particle-science-pack" or similar. I love both mods.. and the more science, the better lol

I'm glad you are enjoying it. I renamed the item like you suggested, to make the mods compatible.

Thanks!

Hello, i tested compatibility with both mods, it works.
Also, tested with Plutonium Energy by JohnTheCoolingFan, still works =).
My suggeston is to make plutonium insted of uranium as part of one of the data packs if Plutonium energy is enabled.

Sure, I'll add a plutonium recipe. I estimate that plutonium is 3 times as expensive than uranium, so I will account for that difference in the cost.

For me it unfortunately does not work. When adding this mod, it replaces the nuclear science pack

I can't reproduce the problem, so this mod is likely not the cause. Does it happen if you uninstall all mods except for Particle Physics, Nuclear Science, and their dependencies? You can start a new game and look for the nuclear science pack in the technology tree.

perhaps you could rename it from pack to science?
or at least have "science" somewhere in the name so it can be ctrl-F'd in the production statistics
