Using nucular's ore, fuel, depleted fuel and plutonium sprites would make items use some variety so not everything is a greenish block.
Nuculars weapons would be a nice module to add as well.
Here's the json migration script I use in my private merge of nucular and reactors so i don't loose several k of ammo and resources:
{
"entity":
[
["uranium-cannon-projectile", "du-cannon-shell"],
["uranium-bullet-magazine", "du-magazine"],
["nuclear-fuel", "enriched-fuel"],
["spent-nuclear-fuel", "spent-fuel"]
],
"item":
[
["uranium-cannon-projectile", "du-cannon-shell"],
["uranium-bullet-magazine", "du-magazine"],
["nuclear-fuel", "enriched-fuel"],
["spent-nuclear-fuel", "spent-fuel"]
]
}
