When I tell my spaceship to refill on fusionfuel as interrupt and send it to a new planet it doesn't check for the interrupt condition

Interrupts are being checked when a waiting condition just became true and the platform is about to leave.

If you manually click a destination, interrupts are not checked. Your Vulcanus waiting condition can never be true, because it contains 2 mutual exclusive conditions (a passenger cannot be present and not present both at the same time). The interrupt might trigger when the platform is about to leave Nauvis, but only if some passenger is present.
