摘要： A system for refueling a nuclear reactor is provided. The system includes a lower reactor vessel with a plurality of fuel rods and a plurality of control rods disposed therein, the lower reactor vessel further comprising an upper flange. An upper reactor vessel is provided which encloses a steam generator and a pressurizer, the upper reactor vessel further comprising a lower flange that matingly engages the upper flange of the lower reactor vessel. A transporter surrounds an outer surface of the upper reactor vessel, wherein the transporter is configured to translate the upper reactor vessel vertically toward and away from the lower reactor vessel and also to translate the upper reactor vessel horizontally toward or away from alignment with the lower reactor vessel.

摘要： A nuclear reactor includes a pressure vessel (10), and a control rod assembly including at least one movable control rod (18) comprising a neutron absorbing material, a control rod drive mechanism (CRDM) (14) for controlling movement of the at least one control rod, and a coupling operatively connecting the at least one control rod and the CRDM. The coupling includes a first portion comprising a first material having a first density at room temperature, and a second portion comprising a second material having a second density at room temperature that is greater than the first density. In some embodiments the coupling includes a connecting rod (30) including a hollow or partially hollow connecting rod tube (90) comprising a first material having a first density and a filler (92) disposed in the hollow or partially hollow connecting rod tube, the filler comprising a second material having a second density greater than the first density.
