Abstract
Abstract A machine for dismantling, unloading and transferring to a disposal facility, nuclear reactor structure and/or components, which have been irradiated during operation of the reactor. The machine includes in one example a gantry (12) mounted on a rigid, undismantled part of the reactor such as rails (10) on the refuelling level (9) of the reactor, a carriage (14) angularly movable on the gantry, a platform (14<1>) movable linearly on the carriage, a mast (16) on and axially movable relative to the platform, a manipulator (17) mounted on the mast for angular and linear movement relative thereto, a variety of tools (18) selectively mountable on the manipulator for effecting dismantling of reactor structure and/or components, and hoist means (26) movable along a beam (21) rotable about the reactor centre line and alignable with other beams (23, 24) to allow transfer of the hoist means from one beam to another. Alternative arrangements for varying the elevation of the mast are also disclosed. <IMAGE>

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
123 words
A machine for dismantling, unloading and transferring to a disposal facility, nuclear reactor structure and/or components which have been irradiated during operation of the reactor, such machine having a gantry, means for mounting the gantry on a rigid undismantled part of the reactor, a carriage movable on or about said gantry, a mast mounted movably or non-movably on said carriage, a manipulator mounted movably on said mast and capable of supporting and operating a variety of tools for effecting dismantling of said structure and/or components, and movable hoist means separate and separately operable from said manipulator, for effecting, either in conjunction with said manipulator or without, unloading and transfer of dismantled structure and/or components, all the functions of said machine being controllable remotely.
Claim 2
Dependent Claim
123 words
A machine for dismantling, unloading and transferring to a disposal facility, nuclear reactor structure and/or components which have been irradiated during operation of the reactor, such machine having a gantry, means for mounting the gantry on a rigid undismantled part of the reactor, a carriage movable on or about said gantry, a mast mounted movably or non-movably on said carriage, a manipulator mounted movably on said mast and capable of supporting and operating a variety of tools for effecting dismantling of said structure and/or components, and movable hoist means separate and separately operable from said manipulator, for effecting, either in conjunction with said manipulator or without, unloading and transfer of dismantled structure and/or components, all the functions of said machine being controllable remotely.
Claim 3
Dependent Claim
32 words
A machine according to claim 1, wherein the said hoist means is or are movable along a beam mounted diametrically or radially for rotation about the centre line of the reactor vessel.
Claim 4
Dependent Claim
24 words
A machine according to claim 2, wherein said hoist means is or are capable of being transferred to other beams, either fixed or rotatable.
Claim 5
Dependent Claim
23 words
A machine according to any of the preceding claims, wherein the said hoist means includes more than one hoist, operable and movable separately.
Claim 6
Dependent Claim
35 words
A machine according to either of claims 1 and 4, wherein the said hoist means is or are mounted on said mast so as to be capable of both rotatable and radial movement relative thereto.
Claim 7
Dependent Claim
36 words
A machine according to any of the preceding claims, wherein the mast is a rigid structure and the carriage is moveable upwardly or downwardly relative to the gantry so as to raise or lower the mast.
Claim 8
Dependent Claim
36 words
A machine according to any of claims 1-5, wherein the mast is made up from a plurality of sections, and sections can be added to or taken from the mast so as to vary its elevation.
Claim 9
Dependent Claim
30 words
A machine according to any of claims 1-5, wherein the mast is telescopic, and means are provided, operable remotely, for telescoping or extending the mast to give a required elevation.
Claim 10
Dependent Claim
34 words
For dismantling, unloading and transferring to a disposal facility nuclear reactor structure and/or components which have been irradiated during operation of the reactor, a machine substantially as described with reference to the accompanying drawings.
Claim 11
Dependent Claim
34 words
For dismantling, unloading and transferring to a disposal facility nuclear reactor structure and/or components which have been irradiated during operation of the reactor, a machine substantially as described with reference to the accompanying drawings.
