Nuclear reactor

An emergent chain reaction, on real reactor kinetics.

  • @flare-engine/ecs

Neutrons multiply on fissile atoms and are absorbed by control rods. Nothing is scripted — the criticality you watch is the population balance of the agents themselves, held on verified point-reactor physics.

What it uses: @flare-engine/ecs for the entity world and its queries, @flare-engine/core for the loop and the coroutine choreography, @flare-engine/animation for the control-rod tweens, @flare-engine/particles for the fission bursts, @flare-engine/math for the numerics, and @flare-engine/render-web + @flare-engine/postfx for the surface and the glow.
