Yes, Greg has tweaked plutonium as well as thorium and the reactor planner was never updated to respect the changes, I would recommend testing the designs in the Computer cube as it tends to be much more accurate.
Exactly, this worked just fine in Unhinged http://www.talonfiremage.pwp.b…vva6azf9gcbd07o2eca9pxjwg
The Computer Cube is extremely slothful. Is there any other way to make simulations, calculations? I'd do it with pen and paper, but I don't really understand how the components work exactly or how dynamic is the Nuclear Reactor's heat system. Any suggestions?
