Hi,
Here you are a few screenshots of my power plant. It's my first project since I discovered Industrial/Buildcraft/Tekkit/Technic mods so please, don't crucify me here I am using the steam produced by the reactor to power Railcraft industrial engines, which in turn produce MJ energy converted to EU in EV pneumatic generator. I find this design to be pretty much close to the real thing. This is the LZH-condensator cooled type reactor whit the defense in depth engineering resulting in triple protection including monitoring the pressure in the primary cooling circuit, coolant injector alarm and of course overheat protection system. Like I said this is a small power station (built in survival mode) outputting 2200 EU/t but for now it's enough.
PS.
I apologize in advance for grammatical mistakes. I'm using translator and what's left of my English classes.
