Here is my latest survival project, its a large superheated steam 5x5 reactor producing roughly 940-950 EU/tick. There was a lot of trial and error involved in making this reactor but it was a lot of fun and it took an immense amount of resources and time. The mods i used primarily is ic2 (ofc) steve's factory manager and also a bit of ender io. However ender io is completly optional and could be skipped completly. Im using the latest version of Bevos tech pack from the AT launcher
The reactor is a standard 5x5 reactor with 2 liquid input/outputs in addition to the standard components. The design i used for the reactor is High power High running cost reactor made by SSD, which normally produces 420 eu/tick at an effiency of 3.
Here is a picture how the setup looks when its running:

Hot and cold cooling fluid is pumped in and out of the reactor using ender io's ender fluid pipes. They pump the fluids to one tank each (thermal expansion) as a middle storage so that it's easier to keep track of the amount of fluids in the system. The hot cooling fluid is then transported from its tank into 14 liquid heat exchangers and after usage is transported out of the heat exchangers and the other tank where it is again pumped into the reactor using ender io.

as the reactor produces 1344 heat i used 1200 (or 12 heat exchangers) to heat 6 steam generators producing 600 mb of super heated steam. The remaining 144 heat is used in 2 sterling generators as they dont require even heat.
Below is a picture of how the setup looks like:

As one can see ive built a tower with identical layers for the turbine consisting of 2 liquid heat exchangers, 1 steam generator, 2 kinetic steam generators, 2 kinetic generators and 1 condensor. For the last layer you use 1 liquid heat exchanger and a stirling engine for each 100 HU remaining (1 if less than 100, 2 if between 100 and 200). This setup is easily modified to any size reactor by adjusting the height of the turbine tower.
Here is a picture of the turbine layer in detail:

To handle the distilled water in the system i used steves factory manager. It pulls the condensed distilled water from the kinetic steam turbines (including the superheated steam turbine as it gets a bit of regular steam at startup) as well as the rest of the distilled water from the condenser. Each condenser has 2 heat vents to be able to handle the amount of steam. The distilled water is pulled into a drum for middle storage so i can keep track that the amount of distilled water in the system is not decreasing. Steves factory manager then pulls the distilled water from the middle storage back into the steam generators. Each steam generator can take 10000 mb of distilled water so for this system a minimum amount of distilled is 60000mb. This part could be optimised by only filling a portion of the steam generator or supplying it with the same amount as is used , however that felt overly risky and complicated over making more distilled water. Each steam generator is set to 221 bar of pressure and 1 mb/tick. Distilled water can easily be created using a electric heat generator, 1 steam generator and a condenser however it requires the usage of 100 eu/tick. This could be decreased to 50 if you put it through a kinetic steam turbine first at the cost of a larger investment and higher complexity.
The result is this

The steves factory program is quite simple and just contains 4 input and output loops

If this feels overly complicated each layer of steam turbines could be changed for 2 sterling engines (which is soooooooo much simpler and cheaper) this would produce about 630 eu/tick instead of 950.Also you consume the turbine in the kinetic steam turbine after a while which means it also has quite a large running cost of steel. Just the initial investment was 360 steel to create the turbines blades. I haven't tested for how many cycles they last yet.
I recommend having a quarry if you are building this as it is extremly expensive. The complete number of components used was the following:
1 acess hatch
1 redstone port
1-2 fluid ports (you could probably get away with one using steves factory manager)
94-95 reactor pressure vessel blocks
1 nuclear reactor
6 reactor casing
28 overclocked heat vents
11 component heat vents
1 component heat exchanger
7 quad fuel rods
as well as
14 liquid heat exchangers
140 heat conducter
6 steam generators
2 sterling engines
12 kinetic steam generators
12 steam turbines
12 kinetic generators
6 condensers
12 heat vents
As well as some piping and steves factory manager stuff.
The easy version would instead use:
14 liquid heat exchangers
140 heat conducters
14 sterling generators
A good advice for building the superheated steam layers is to make just one layer that you run on lava(just remember to void the cold lava afterwards using buildcraft void pipes) When you have the first layer up and running on lava you replicate this layer for the other layers and connect the 5x5 generator. I do not recomend doing a lot of trial and error with a large 7 quad core reactor...
The reactor has been working flawlessly so far and i haven't detected any problems however i will make some long term stability test to make sure im not loosing distilled water or coolant. I also have to check how long the turbines last before they need to be changed.
What do you guys think?
Edit: I had to change around the cables a bit as i think it was a bad idea to block the second kinetic steam turbine. the second kinetic steam turbine got filled with steam for some reason due to blockage. So far this seems to have worked as i have seen no problems now (for like 2 hours). It seems i might have a small leakage of distilled water however im not sure yet.
Ps: This is a large post so some errors are bound to have sneaked in, feel free to point them out and i will fix it.
