Zusammenfassung:	A control rod drive mechanism for a nuclear reactor including means for preventing the excessive compressive loading of the control rod by the control rod drive motor. The drive motor is constructed with a "floating" rotor assembly for allowing it to translate upwardly in response to a compressive overload. The rotor is defined as comprising two pivoted segments with one of the rotor segments adapted for engaging a stop provided for the pressure housing of the control rod drive mechanism. When a compressive overload occurs, the rotor translates until the housing stop and rotor interengage so that the rotor torque is transferred from the control rod to the pressure housing. A compressive overload condition exists whenever the friction loading exceeds the combined weight of the control rod and associated components.
