[MERGED PR] Nucular Fishin' Engine

[amylizzle]

I like this! Some feedback:

• Why a new fuel rod item? Why not just let people make rods directly (with metal/etc. sheets) and slot them in?
  
• Neutron Moderators are important in nuclear reactors but I didn't see any mention of them in the design doc. Making the reactor a big container might be good enough. It would be cool if chemicals besides Water had different effects (e.g. Radium produces passive power but makes it easier to meltdown, etc.) The TEG uses viscosity, maybe you could use something else like heat capacity?
  
• It would be nice if a meltdown was less "Nuke time, I win" and more "Catastrophic levels of radiation", like the random event, even more than the black hole's. A TEG failure burns you alive, a singuloose eats the station, I think it would be appropriate for a meltdown to emit unbearable amounts of radiation, a kind of disaster trinity. Maybe with just a bit of explosions and heat as a treat, since you are including piping.
  

I don't have anything to say about how the power will be calculated since I'm not familiar with the inspirations you listed.
Overall, it looks great so far!

Hi, thanks for the feedback!
1) Honestly I've been thinking about ditching the fuel rod item, since as you say, any material component is basically a fuel rod. The counter to that is that I'm messing with mass, so fuel rods are 2-3x more massive than other components, and so it's more efficient to have your fissile material in a fuel rod than say, in a gas channel. It's all still very much rough edges, so a lot of this is subject to change.
2) Neutron modulation is being handled relatively simply, in that neutrons are either low, medium, or high velocity and that collisions knock them down a velocity step (except when they hit fissile material and are consumed). Collision chance is currently determined by density, but I may look into other material properties as well. Also, plasma is going to act as an anti-moderator, accelerating neutrons, because that's kind wacky and very much in the flavour of plasma. No liquids though, because the liquid handling system sucks. This here is a gas cooled/moderated reactor
3) That's very much the plan - neutrons that aren't absorbed by the fuel are going to leak out of the reactor, and a meltdown is going to be less "boom" and more "oh god everything is super radioactive and melted and stuck in the reactor and so very hot". The turbine might explode, there will be plasma fires, and ungodly amounts of rads produced.
