Dashport construction for a nuclear reactor rod guide thimble
This patent describes a control rod guide thimble having a main hollow tube defining a substantial portion of the length of the guide thimble. It comprises: a lower tubular portion of the man hollow tube; and an auxiliary hollow tube having concentric exterior and interior surfaces, the auxiliary tube being inserted in the lower portion of the main hollow tube and having an outside diameter slightly less than an inside diameter of the main tube to permit a close fitting relationship between the exterior surface and the auxiliary tube and an interior surface of the main tube lower portion, the auxiliary tube having an upper end portion with an inside surface portion in axial cross-section flaring in inclined relation upwardly and outwardly to provide a tapered transition extending between and connecting the interior surface of the auxiliary tube with the exterior surface thereof; and an end plug attached to a lower end of the auxiliary tube.
