Chapter 3: Building the reactor components.
This will take some time since, as mentioned, I need some information I don't yet have about exactly how to build the multiblocks. Anyway, I wanted to comment on resources first. All in all, my calculations indicate that it isn't *THAT* bad. You won't need a five-digit number of anything but lodestone, and possibly iron. One problematic area may be wool since that may be unexpected for some. You'll need about 8-10 K, but a moderately sized sheep farm should be able to make this in a reasonable time. The most likely bottleneck is is the Lodestone. You'll need more than 30K of the stuff, which is 6-7K even with ore quintupling, and it spawns at elevations 60-80 so most targeted automining operations won't get all that much of it. I highly recommend going to the Deep Dark for this, because the ground in that dimension is at elevation 80, which means that the topmost 20 layers below are all spawn locations for Magnetite.
As an aside, here a view of my ore processing facility. Ores are exporting into the extractor by bus, then the flakes are smelted in the two Elite Factories. They aren't quite enough to keep up, but I am not constantly processing but only if I need metals, and up to 7K ore can be processed before the backlog is more than the gold chest can contain. The Cyclic Assemblers are for the items that come out of the smelting and need to be crafting into their final shapes, such as Thaumcraft shards, calcite, fluorite, magnetite, Magical Crops essence and one or two more. I've found that cyclic assemblers are significantly faster than using ME buses for unconditional autocrafting (you can't use ME Interfaces because their export function doesn't have an "always craft" option). Also note the two unifiers. I dislike having different versions of metals around.
Next, the site for the fusion reactor. I couldn't avoid some landscaping since this needs a 40x40 blocks area. The blueprint highlighter helps me with placing the different components, but that has never been the most difficult part for me. I did mention I wanted the place to look somewhat nice, and I think I found such a location, near a river at the border between a Moor and Mesa biome, about 120 blocks from my base. .
Now I'm off for some out-of-the-game planning. CU later.
AND HOW THE HELL CAN I BE SUCKED INTO A GAS TURBINE THROUGH A COVER, DAMN IT?
Edited to add:
I found that fuel pellets can be pulled out from the bottom of a fuel core once they're fully depleted. I find this odd. Actually, I don't even know where the thing went. It may end up as depleted uranium or have vanished completely, I wouldn't know the difference. Shouldn't have kept the test automation running.
