Integration of Large Radiators with Nuclear Electric Spacecraft Systems 640154

Some of the more significant interactions between the radiator and vehicle of nuclear electric spacecraft are considered. This includes the selection of indirect versus direct condensing in the radiator; meteoroid armor and bumper criteria; booster constraints; aero shroud and structural integration; the significance of headers and feeds, electric transmission lines, and nuclear radiation shielding; and the magnitude of the structure contribution to system optimization. It is concluded that a conical or cylindrical radiator is the lightest and most generally applicable configuration from an overall system viewpoint.
