Abstract – This document outlines the tasks needed to remove n_TOF Target 2 in order
to allow its replacement with Target 3. The tasks include removal of the equipment and
items in the vertical beam pipe to gain access to the n_TOF target 2 from the technical
gallery. It is assumed the detectors and the associated equipment have been removed
before this work starts. This document identifies tasks where remote handling will be
