@Nertea Some KA-engines (Scylla, Poseidon, Neptune, Eel) show no static waste heat in the lefthandsided parts properties of the partslist. You have to look them up in the PAW. But others nuclear engines do show the maximum waste heat (Deliverance, Liberator, Emancipator) in the part info box of the left hand sided part menue of the VAB. This heat variant scales by thrust. Is this behavior in the part descripton intended, or got theĀ  info about the static waste heat of the engine w
