Suggestion: Nuclear Reactor Manager
What it is: a block, similar to the other item-automation blocks, but it can only work when used next to a Nuclear Reactor. It can be set to remove near-depleted cells, replace fuel rods in specific slots, remove nearly melted cooling components (coolant cells/heat vents), input Depleted Isotope Cells, output Re-enriched Uranium cells, and a few other things that I may have forgotten that are major components of Nuclear Reactor operation.
GUI/Usage: The GUI has 8 slots; 4 at the left, in a 2x2 grid, and the same at the right. Under the one at the left is the word ''INPUT'' and under the right grid is the word ''OUTPUT''. Each slot can take any reactor component. Under each ''OUTPUT'' slot is a gray button and a green bar; clicking the Green bar cycles it between 100%, 75%, 50%, and 25%. Any items of the type set to that slot, that are in the reactor and at or below the value displayed on the green bar, will be extracted from the reactor to an attached inventory at a configured output-side of the block. The Gray Button, when clicked, pulls up an inventory grid the exact same size as the reactor's inventory, and clots can be clicked to change them from ''not used'' (gray) to ''extract from here'' (red). Items of the selected type, at or below the set damage value (not applied to non-damageable items), and in the highlighted slots, will be extracted to the connected inventory on the configured output-side; if no specific slots are highlighted, all items of the type, at or below set damage value, will be extracted. the Input grid also has the gray buttons, but no configurable damage bars. Clicking the gray buttons will have the same function as for the Output grid.
Crafting: It would require two of the most expensive automation machines available, some Data Control circuits/computer monitors, and some other balancing stuff like Electrum plates/Tungstensteel plates.
EU usage: Uses 8 EU per item moved.
Or, when the planned reactor overhaul happens, add a Liquid-fueled reactor, that needs liquid Uranium/Plutonium/Thorium to operate, and produces small amounts of Liquid Depleted Uranium per 1000 mB of Liquid Uranium, and Liquid Depleted Thorium/Plutonium for those fuels.
Liquid fuels could be made by heating the fuels in a machine contrasting to the Vacuum Freezer, made to take an input Dust/Ingot, liquify it, and move it to its internal storage tank. If there is any of a liquid in the internal storage, it will only accept the material that is melted into that liquid.
Either of those would be awesome.
And just one more thing: What about a high-tech machine, the Fusor, that takes input energy to fuse 2 substances? It would take significantly longer than a Fusion Reactor, and work similar to the Alloy Smelter. For example, if the user inputs Deuterium and Tritium, it produces Helium (gaseous, not plasma). This would offer users a way to create substances that they don't have easy access to, at the cost of lots of EU. It could drain an entire MFE in only 2 operations producing Helium, and the heavier that the input items are, the more energy it will consume to fuse them - so producing, say, 1 Iridium, may drain 2 MFSU's or more.
It would still require high-tech machine blocks and lots of other very expensive stuffs, though, to keep it balanced.
