I just built one of these complete with 3 cooling towers working in series. I found that chaining the cooling towers with filters connected to ejectors, I could pulse the filters 6 times and then pulse the ejectors 6 times to move the partly cooled cells. A regulator would probably work too, but I didn't want to waste coolant cells to configure the inventory.
One question: should I cycle my reactor at exactly the micro-cycle time, or should I cut it down by a second or two? I ask because I had a problem with coolant melting when I tried it at exactly the micro-cycle time. I'm guessing I should cut it down because the time is extrapolated from the time it takes for the reactor to fail.
Also, there are a ton of cooling tower designs. By reading the whole thread, I sort of come to the conclusion that this is the accepted best 6-chamber one. Is it a good idea to use a bunch of 1-chamber ones instead? Is there a better 6-chamber design?
Oh wait. My reactor just blew up *sigh*. I probably messed up somewhere. Back to testing.
