So I’m thinking of using water and putting a 1x1 block with a moderator rod in the middle, surrounded by 4 2x2 reactor blocks. If the inner ring of the 2x2 blocks are filled with 8 cobalt-60 rods, the moderator will see all 8 and so reflect 8x neutrons right? So each fuel rod emits 2 neutrons to the moderator and gets back 16, plus 2 from its neighbor, plus 2 of its own for a total of 20 neutrons on each rod, which exceeds its factor making this a supercritical setup? Is that correct? So the next second its emission will increase by 18/16 or a bit more than one neutron, so now it emits just over 3 neutrons and gets a bit more than 24 from the reflector plus a bit more than 3 from its neighbor for a total of nearly 28 neutrons, and this will keep increasing until it goes boom. Do I have this right?
Also the neutron counts are only updated once a second, but is the heat produced is 1 HU per tick per neutron or per second?
Maybe another example: a single 2x2 reactor with 4 rods using industrial coolant ( I assume that’s the IC2 stuff right? ). That gets 8 emission so 16 from its two neighbors, with a 1/32 factor so you get about another half a neutron of emission, taking it up to a bit more than 8.5 neutrons per rod, plus the 8 self neutrons for 25 neutrons per rod or 100 HU/t total output? Which would give slightly more than enough heat to keep a dense invar and a normal invar heat exchanter/boiler running and producing 192 steam/t?
