In the latest release of ER2 as of this post, (ExtremeReactors2-1.18.1-2.0.38.jar) while you are able to use solid uranium as solid fuel to input into a reactor directly, the fluidizer will not recognize it (forge:ingots/uranium or forge:storage_blocks/uranium) to turn it into yellorium liquid fuel.
I assume yellorium/uranium are the same thing as both can be used in any recipes that involve them, correct me if I'm wrong.
