Power cells generate heat and power. Each cell in a given tile gives a pulse to each adjacent tile. Heat and power scale with the number of pulses recieved. Pulses Recieved (U), Single cell base power (P), Single cell base heat (H), Cell count (C) (M) 1 for single, 4 for double, 12 for quad Power: P * (M + U) Heat: H * (M + U)^2/C Neutron Reflectors provide a power bonus to adjacent cells stacking additively with each other. Capacitors increase the total energy capacity of the reactor. platings increase the total heat capacity of the reactor. Vents dissipate contained heat. Base heat capacity (C), Base ventillation (V), Sum of all capacitor tiers (Ct), Sum of all plating tiers (Pt), Improved Heatsinks level (S), Active Venting level (A) Ventillation: V * (1 + A * Ct / 200) * (1 + S * Pt / 200) Heat Capacity: C * (1 + A * Ct / 200) * (1 + S * Pt / 200) Exchangers balance heat between themselves and adjacent components. Base heat capacity (C), Base transfer (T), Sum of all capacitor tiers (Ct), Sum of all plating tiers (Pt), Reinforced Heat Exchnagers level (R), Active Exchnagers level (A) Transfer Rate: T * (1 + A * Ct / 200) * (1 + R * Pt / 200) Heat Capacity: C * (1 + A * Ct / 200) * (1 + R * Pt / 200) Inlets move heat from adjacent components into the reactor. Base transfer (T), Sum of all capacitor tiers (Ct), Sum of all plating tiers (Pt), Reinforced Heat Exchnagers level (R), Active Exchnagers level (A) Transfer Rate: T * (1 + A * Ct / 200) * (1 + R * Pt / 200) Outlets move heat from the reactor into adjacent components.

Particle Accelerators produce exotic particles based on the heat passing through them each tick. Max Heat BEFORE upgrades (m), Max Heat (M), Heat throughput (H), Tier (T), Enhanced Acceleration Levle (E) Particle production: (Ln(min(M, H)) / 10 ^ (5-T)) * (min(M, H) / m) * 10^E Ln(x) - The natural log (base e) of x min(x, y) - the lowest value between x and y



A modification of Reactor Knockoff.

    Experimental Upgrades

    Rebooting the reactor will remove all parts, regular upgrades and money. Only your current experimental upgrades and EP will stay with you.

    All of the above applies, however this will undo all your experiment upgrades and refund all your Exotic Particles.
