Reactorcraft Help?

[Ascend]

Hello again,

I seem to be having trouble setting up my first HTGR from Reactorcraft. The problem is that my reactor will not heat up, no matter what I try. The setup shown in the following pictures has:
a) sufficient TRISO fuel and CO2 gas
b) all faces of the reactor/CO2 heat exchangers covered
c) total of 4 reactor cores and 4 heat exchangers (I know this is a bad ratio)

Spoiler: Pictures

The reactor never gets above ~80 degrees, which is a rather large problem considering you need ~800 degree operating temperature.

Any help is appreciated, thanks!

You need more TRISO fuel. The more TRISO fuel in the cores, the hotter it will get. Ideally, you'd fill it up to the brim.

Stuff is cheap to make anyway.

You'll also get more heat if you instead surround a single heat exchanger with the reactor cores.

The more TRISO fuel in the cores, the hotter it will get.

From the reading I have done, the reactor temperature will not depend on the amount of fuel in the core. This can be confirmed as I filled the reactor up right after I posted this, and it still has an average temperature of what seems to be about 90 degrees.

Spoiler: Specifics

The reactor has a passive 7% chance each tick to add 20 degrees of heat to the reactor. This chance is (I believe) independent of the amount of fuel in the reactor.

You'll also get more heat if you instead surround a single heat exchanger with the reactor cores.

I do not believe this matters, as the temperature of the reactor core itself does no reach high temperatures. Surrounding a heat exchanger with 8 reactors at 80 degrees will not achieve the ~800 degrees I require.

Thank you for your suggestions though.

I apologize, but after reading a bit of the source that @Reika so graciously made available to us, I am realizing that @Wagon153 is correct.
The reactor will have a chance each tick to add 20 to the temperature of the reactor, and this chance depends on the reactor size as shown below.

Spoiler: Chances

if (size >= 128)
return 1; //20
else if (size >= 72)
return 2; //12
else if (size >= 48)
return 3; //8
else if (size >= 36)
return 4; //8
else if (size >= 24)
return 6;
else if (size >= 12)
return 4;
else if (size >= 6)
return 2;
else
return 1;

I believe "size" refers to the total amount of reactor cores attached to one another.

Glad you figured it out. Also, my second tip was more directed towards once you managed to get it to heat up. It of course wouldn't help if it wasn't heating up in the first place.
