  The ITER neutral beam cell will contain up to three heating neutral beams and
one diagnostic neutral beam, and four upper ports. Though manual maintenance
work is envisaged within the cell, when containment is breached, or the
radiological protection is removed the maintenance must be conducted remotely.
This maintenance constitutes the removal and replacement of line replaceable
units, and their transport to and from a cask docked to the cell. A design of
the remote handling system has been prepared to concept level which this paper
describes including the development of a beam line transporter, beam source
remote handling equipment, upper port remote handling equipment and equipment
for the maintenance of the neutral shield. This equipment has been developed
complete the planned maintenance tasks for the components of the neutral beam
cell and to have inherent flexibility to enable as yet unforeseen tasks and
recovery operations to be performed.
