Question

Having fully pressurized the bridge compartment, Zeta Anderson enters and begins checking the ship's systems. The now covered over entry point is obvious, and clearly some of the controls have been destroyed. The engine controls are undamaged, and she finds that the engines are still running and can provide mechanical energy to do work like a heat engine with a hot reservoir of 700 Kelvin, and a cold reservoir of 350 Kelvin (nuclear powered, with large cooling radiators). What is the maximum theoretical efficiency for these engines? Why does the ship need these cooling radiators in deep space?
