Nuclear waste is not going into a chemical tank even though there is an item in JEI for it stating it can, do not know if this was supposed to be removed or is not working correctly.
Added screenshots of issue.

intended by mekanism. you can't store nuclear waste in chemical tanks. only in pipes/waste barrels. it also cannot be passed through entangloporters. Creative items do make that exception a little confusing, I admit, but they're for creative testing.
