Confirming that Tritium Breeding is not functioning normally - In .24/.25, rates were proportionate, and using an upgraded 3.75m fusion reactor running at high usage (microwave transmitter maxed-out), I could reliably have a (very slow) gain of Tritium over time regardless of time acceleration. Here, even with increased Charged Particle ratio for the DT Fusion mode, Tritium Breeding is unsustainable...at time accelerations below 100x. At and above 100x, there is a sizable and disproportionate gain. Testing further, by editing the He3 Cryostats reserves a little, it seems that the tritium breeding rate is not dependent upon the amount or rate of charged particles at all. DT, DHe3, and 2He3 modes all have the same exact rate of tritium breeding. It is dependent, linearly, on total reactor output/heat, and non-linearly on time acceleration. Serious problems for maintaining a fusion-powered microwave-beaming satellite. Edit: Actually, the increase in gain does appear to be linear after 100x...for some reason, it just magically becomes viable and the signs flip when time is scootched up past 50x. Edit2: So, a temporary fix for myself is just decreasing fusion fuel consumption by a single order of magnitude. This makes tritium breeding sustainable at 75% reactor output for the 3.75m High-Q Tokamak. I have noticed that at 50x time with this vessel operating at 95% reactor, the tritium rate is -0.01. However, when I increase this to 100x time, this goes instead to -0.18, a factor of at least 9 times more. Something going on with the simulation at 100x+ causes something silly not to happen to breeding rate, but reactor fuel consumption. The Deuterium rate goes from 0.18 at 50x to 0.00 at 100x...magically it isn't consuming fuel at that point. I'm guessing this only for a simulated ship, though, not a vessel in background which should behave normally. Something really weird is going on here, as well. According to the reactor control panel , normally (without my edited consumption rate) the consumption rate for Deuterium and Tritium sit nicely at 32 liters per day, and the breed rate here shows 155.2 liters per day for tritium. Somehow, this is not translating accurately to either consumption or breeding rate, though my bet is on consumption. This vessel has been up for a total of 2.5 hours and (at its 1/10th rate of consumption) has already lost 4 units (liters???) of Deuterium. Deuterium rates: @50x, 0.08 - @100x, 0.00 - @1000x, 0.04 - @10,000x, 0.40 (oscillates to 0.33). Again, these rates are about one tenth what other users will experience.
