I was looking for a large nuclear reactor and came across this one, and now have it up and running. I have some notes for people who are trying to build & run this...
* WATER. Holy hell this takes a lot of water. My first attempt was to use barreling... Failure. In order to get this to run you'd need around 48 Level3 assemblers with speed modules to de-barrel water, and an equal number to barrel them, and like 18 fully saturated blue belts of barreled water. I tried to just get a SINGLE row of heat exchangers going and I failed. I ripped up the reactor and placed it in an area where 3 small lakes were well positioned for water pumps, and then added extras that wrap around to the last side.
* You should add Roboports! On each side, where the water comes in, you can put 2 roboports. In each diagonal that runs from the outside to the core, you can put two roboports. Then you can remove a few heatpipes and put one more roboport in each straight area as close to the core as you can get without linking the roboport networks. This gives you a total of 20 roboport (5 per quadrant) and lets it self build. It is very important to not allow the central roboport network to connect to your main roboport network!!
* Remove the concrete from the blueprint. It uses 36k concrete to fully cover an enormous area. Once you import the string and make the blueprint, go in and edit it and right-click the concrete to remove it. Do the same for the walls, gates, or lasers if you need. The concrete adds significantly to the build time as there are 3x as many items as *all other items combined*.
* You need to add a few Logistics Robots to the central roboport network to get it to run. I added 10.
* You also need to supply lines on the South side of the base for nuclear fuel and spent nuclear fuel. Instead, I pulled up the underground belts and used an active provider chest to get rid of the spent fuel and a requester to bring in fuel.. Again, be sure you put these OUTSIDE the core, so that it uses your main logistics network.
It really works quite well, so thank you very much.
