Liquid Fluoride Thorium Reactor
At last, we come to the newest reactor in ReC: the LFTR, commonly referred to as just the "thorium reactor." Now, I know...very little about this reactor, in practice, so take everything here with a grain of salt. In short, the LFTR uses molten thorium fuel salts and a little neutron flux (w/ some heat) to create its own neutron flux and, thus, making power.
Now, the LFTR is logistically more complicated than most any other reactor: simply creating the LiFBe fuel salts to operate the reactor can be somewhat cumbersome and difficult to manage without some help. That's why I'm here!
First off, you'll need a centrifugal fluid extractor, which I discussed earlier in this thread. Place it on and near some lava in the proper conditions in either the Overworld or Hell (Hell is preferred, since it gives more per operation) and power it to begin extracting
lithium. This is part one of
four of your fuel production.
Next, you'll need some source of emeralds, and preferably in mass amounts. I prefer Magical Crops + AgriCraft emerald farms for this, but a TiCon villager farm would work just as well. You'll need to put these emeralds through a grinder to get
emerald dust. This is part two of your fuel production.
After that, you'll need a goodly amount of
fluorite. If you've got a regular fission reactor running, already, then you likely have some source of them secured. Once you've got that, put that, the emerald dust, and the lithium thru a
uranium processor, the same kind you use to make UF6. From that, you'll get LiFBe, the base for your fuel salt. However, you're not
quite done. You've still got one part of fuel production left!
Lastly, you'll need to dip into RoC machinery a bit. Pop down (and power) an
fuel enhancer and run the LiFBe through it,
as well as thorium dust. Out of that, you'll get your molten fuel salt: LiFBe fuel. To break it down for those who prefer to see things visually:
(Please excuse my poor visual design abilities. I'm not very good with CAD, lol.)
Now, then! Once you've got all that, you can just dump it into your thorium fuel cores an-okay, I was lying. Its not that simple. Ya see, thorium on its own isn't terribly fissile, not like its brothers uranium and plutonium. Good ol' Thor needs a few things to get going in the morning: neutron flux and heat. Neutron flux can pretty much only come from standard fission cores, as only fission neutrons work, and breeder neutrons are specifically made to
not work. As for heat, your thorium fuel cores require at least
400 Celsius to begin operating. Once neutrons from another source start hitting your cores and they get to the requisite level of heat, they'll start generating neutron flux all on their own like big boys! The best part is you can get the hot LiFBe fuel out of the deal, cycle it thru a heat exchanger, and get more steam. If memory serves, you can also use standard boilers with thorium reactors, as well.
While the LFTR
does make
less waste than a standard fission reactor (and a
lot less than an LMFBR), that doesn't mean it makes zero waste. You also want dump valves at the bottom of your thorium fuel cores: if things get too hot, they'll activate and dump everything out. It'll be a bit of a toxic mess to clean up, but it'll also be a lot
less of a mess than a complete meltdown. Thankfully, the LFTR's very nature helps minimize risk: the hotter the fuel cores get, past a certain point, the less reactive they become, basically the opposite of a LMFBR. All this works to make a LFTR a lot safer than its cousins the fission and LMFB reactors.
How does this all work in practice? ...I honestly don't know, I've never gotten around to it, alas. At some point, I may experiment some in a creative world to see what the fuss is all about and just how to operate this bugger, but for now, the LFTR is something of a mystery, to me.
Next time, I'll get into some of the precursors for the point of insanity: fusion!
Addendum
I apologize for this taking so long. I've recently started back at school and am going to actual, real university (instead of community college), so I'm having to get used to not only a new campus with new rules, but also new classes on top of it. I have classes every weekday (three on Mo/We/Fri, one of Tu/Th) and I'm pretty much certain things are going to get more involved as time goes on. I'll work hard so, if nothing else, my weekends can remain free, but my non-school time will be drastically cut down for the next sixteen weeks. Again, sorry if I end up being slower than usual...it can't really be helped, unfortunately.
