its just so poorly designed. i love it

@Instant Ramen +

The scaling (in terms of reactor mass vs power) is actually slightly less than linear. For example, Apophys's 1, 10, 100 MW reactors are 14.6, 127, 1060 kg.

@dolium

https://upload.wikimedia.org/wikipedia/commons/4/46/Carbon_basic_phase_diagram.png This phase diagram of carbon suggests that at the ~2400 K core temp of this reactor, >100 MPa of pressure (1000 atmospheres) would be required to keep the diamond metastable, which I do not think is feasible to contain longterm, especially at this temperature.

Yes.

So, you simply have to upscale all of the stuff in the reactor?
Seems doable

@dolium Can't say I know. However the change from diamond to graphite is an actual phase transition and not a interfacial development like metal oxidation, so once conditions are met the entire structure could change at once.

@ThatRedGuy As far as I know, yes; reactors scale linearly and are only limited by manufacturing ability.

Is it possible to have a larger reactor with more power ouput whilst also being realistic?

Very impressive, thank you for sharing it with us.

I made a similar reactor, https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1440264632

Is decomposition of diamond a significant issue? If the pressure inside the core is high enough the rate of decay should be relativly slow once the outer layer transforms.
