About Nuclear Tweaks for Nicer Ratios
From Factorio Mod PortalTweaking the values for nuclear power to make ratios much nicer.
Nuclear Tweaks for Nicer Ratios
Original mod by "kashmira-qeel" here.
This mod reduces the difficulty associated with nuclear power by making the numbers nice and round.
Continued with the blessing of the original creator! :)
Summary of changes:
Nuclear Reactors
- Fuel is no longer wasted when at max temperature
- Energy output rate increased from 40 MW to 60 MW, so one 8 GJ fuel cell will last exactly 8000 ticks (133⅓ seconds)
- Neighbor bonus reduced to +50% (from +100%), meaning each interface between adjacent reactors counts as _one_ additional reactor, rather than two.
Heat Exchangers
- Steam is produced at 515°C (exactly 500°C above ambient temperature) for an energy density of a round 10kJ per unit nuclear steam.
- Heat-to-steam rate increased from 10.3 MW to a round 12 MW, now producing 120 units of 515°C steam per second.
Steam Turbine
- Steam turbines convert 60 steam/second (unchanged) into 6 MW of power (up from 5.82 MW).
Vanilla heat interfaces (Reactor, heat pipe, heat exchanger, steam)
- Maximum temperature changed to 1015°C, exactly 1000°C above ambient temperature.
