Abrégé anglais



A pallet for supporting one of a plurality of tools for a nuclear reactor
retubing operation, the
pallet positionable adjacent to an end-face of a nuclear reactor core having a
plurality of fuel
channel assemblies having longitudinal axes aligned substantially parallel to
each other. The
pallet includes an elongated frame extending generally parallel to the
longitudinal axes of the
fuel channel assemblies for supporting one of the tools for the nuclear
reactor retubing operation,
the frame having guide surfaces for aligning the tool parallel to the
longitudinal axes of the fuel
channel assemblies. The pallet also includes an electrical cable connectable
to the tool and a
hydraulic hose for providing a pressurized fluid to the tool. The pallet is
configured to
interchangeably accommodate another of the plurality of tools using the same
elongated frame,
electrical cable and hydraulic hose.

channel assemblies for supporting one of the tools for the nuclear reactor
retubing operation, the
frame having guide surfaces for aligning the tool parallel to the longitudinal
axes of the fuel
channel assemblies; and
at least one of an electrical cable connectable to the tool and a hydraulic
hose for
providing a pressurized fluid to the tool;
wherein the pallet is configured to interchangeably accommodate another of the
plurality
of tools using the same elongated frame, sensor cable and hydraulic hose.

2. The pallet of claim 1, further comprising a hydraulic assembly coupled to
the elongated
frame for supplying the pressurized fluid to the hydraulic hose.

3. The pallet of claim 2, further comprising an electrical panel coupled to
the elongated
frame for receiving the electrical cable.

4. The pallet of claim 1, further comprising a ram drive for pushing and
pulling the tool
towards and away from the end face of the nuclear reactor core in a direction
substantially
parallel to the longitudinal axes, the ram drive including a ram drive
connector for coupling to
the tool.

5. The pallet of claim 4, wherein the ram drive connector includes a quick
release pin and
bracket for coupling to the tool.

12


6. The pallet of claim 5, wherein the ram drive further comprises:
a push pull chain, the connector coupled to a free end of the push pull chain;
and
a drive assembly including a motor for driving the push pull chain towards and
away
from the end face of the nuclear reactor core.

7. The pallet of claim 4, wherein the ram drive further comprises:
a push pull chain; and
a drive assembly including a motor for driving the push pull chain towards and
away
from the end face of the nuclear reactor core;
wherein the electrical cable and the hydraulic hose are threaded alongside the
push pull
chain for movement with the push pull chain.

8. The pallet of claim 4, further comprising a control system for controlling
the ram drive to
move the tool towards and away from the end face of the nuclear reactor core.

9. The pallet of claim 1, further comprising a Z-axis drive for moving the
elongated frame
towards and away from the end face of the nuclear reactor core in a direction
substantially
parallel to the longitudinal axes.

10. The pallet of claim 1, wherein the electrical cable includes a sensor
cable.

11. The pallet of claim 1, wherein the pallet includes the electrical cable
and the hydraulic
hose.

12. The pallet of claim 1, further comprising a wireless system configured to
wirelessly
communicate at least one of a control signal and sensor data.

13


13. A pallet for supporting one of a plurality of tools for a nuclear reactor
retubing operation,
the pallet positionable adjacent to an end face of a nuclear reactor core
having a plurality of fuel

including a ram drive connector for coupling to the tool;
wherein the pallet is configured to interchangeably accommodate another of the
plurality
of tools using the same elongated frame and ram drive connector.

14. The pallet of claim 13, wherein the ram drive connector includes a quick
release pin and
bracket for coupling to the tool.

15. The pallet of claim 14, wherein the ram drive further comprises:
a push pull chain, the connector coupled to a free end of the push pull chain;
and
a drive assembly including a motor for driving the push pull chain towards and
away
from the end face of the nuclear reactor core.

16. The pallet of claim 15, wherein the motor includes first and second motors
for
redundancy and wherein the drive assembly further comprises a 90 degree dual
input gear box
for converting rotational motion of a motor drive shaft into rotational motion
of a
perpendicularly aligned shaft for driving the push pull chain.

17. The pallet of claim 13, further comprising a control system for
controlling the ram drive
to move the tool towards and away from the end face of the nuclear reactor
core.

14


18. The pallet of claim 13, further comprising a Z-axis drive for moving the
elongated frame
towards and away from the end face of the nuclear reactor core in a direction
substantially
parallel to the longitudinal axes.

19. The pallet of claim 13, further comprising a wireless system configured to
