Abstract
Abstract An arrangement for replacing nuclear reactor core components which are disposed about the axis of an access penetration in the reactor vessel wall, the arrangement comprising a guide tube means, said means being introducable into the penetration where, in an operative condition the tube means communicates the vessel interior with a charging compartment exteriorly thereof and an eccentric carrying a core component engaging member, means rotatably mounting the eccentric in the tube and means for adjusting the rotational axis of the eccentric with respect to the tube axis and further means for adjusting the axis of the tube relative to that of the penetration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall, said apparatus comprising a guide tube, said guide tube being introducable into the penetration where the guide tube communicates the vessel interior with a charging compartment located exteriorly of said vessel, an eccentric, mounting means rotatably mounting the eccentric in the tube, a core component engaging member carried by the eccentric, the eccentric having a vertical axis on which it is rotatable, means for adjusting the rotational axis of the eccentric with respect to the tube axis, means for adjusting the axis of the tube relative to that of the penetration.
Claim 2
Dependent Claim
113 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall, said apparatus comprising a guide tube, said guide tube being introducable into the penetration where the guide tube communicates the vessel interior with a charging compartment located exteriorly of said vessel, an eccentric, mounting means rotatably mounting the eccentric in the tube, a core component engaging member carried by the eccentric, the eccentric having a vertical axis on which it is rotatable, means for adjusting the rotational axis of the eccentric with respect to the tube axis, means for adjusting the axis of the tube relative to that of the penetration.
Claim 3
Dependent Claim
113 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall, said apparatus comprising a guide tube, said guide tube being introducable into the penetration where the guide tube communicates the vessel interior with a charging compartment located exteriorly of said vessel, an eccentric, mounting means rotatably mounting the eccentric in the tube, a core component engaging member carried by the eccentric, the eccentric having a vertical axis on which it is rotatable, means for adjusting the rotational axis of the eccentric with respect to the tube axis, means for adjusting the axis of the tube relative to that of the penetration.
Claim 4
Dependent Claim
113 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall, said apparatus comprising a guide tube, said guide tube being introducable into the penetration where the guide tube communicates the vessel interior with a charging compartment located exteriorly of said vessel, an eccentric, mounting means rotatably mounting the eccentric in the tube, a core component engaging member carried by the eccentric, the eccentric having a vertical axis on which it is rotatable, means for adjusting the rotational axis of the eccentric with respect to the tube axis, means for adjusting the axis of the tube relative to that of the penetration.
Claim 5
Dependent Claim
96 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall comprising a guide tube which is introducable into the reactor vessel through the penetration, a dependent member eccentrically mounted in said tubular member so as to be rotatable on its own axis and on the axis of the tubular member, the dependent member having a cranked portion the lower part of which carries a core component gripping device, and means for adjusting the axis of the guide tube relative to that of the penetration.
Claim 6
Dependent Claim
96 words
Apparatus for replacing nuclear reactor core components which are disposed about the axis of an access penetration in a reactor vessel wall comprising a guide tube which is introducable into the reactor vessel through the penetration, a dependent member eccentrically mounted in said tubular member so as to be rotatable on its own axis and on the axis of the tubular member, the dependent member having a cranked portion the lower part of which carries a core component gripping device, and means for adjusting the axis of the guide tube relative to that of the penetration.
Claim 7
Dependent Claim
29 words
Apparatus as claimed in claim 2 in which the dependent member is movable endwise, said apparatus further including means responsive to such endwise movement for operating the gripping device.
Claim 8
Dependent Claim
25 words
Apparatus as claimed in claim 2 in which the dependent member comprises a rod mounted within a tube and mounted for relative endwise movement therebetween.
Claim 9
Dependent Claim
26 words
Apparatus as claimed in claim 4 in which the dependent member is rotatable on its axis simultaneous with rotation of the tubular member on its axis.
Claim 10
Dependent Claim
24 words
Apparatus as claimed in claim 5 in which there is a fixed ratio between the rotation of the dependent member and the tubular member.
