1   Scope

This part of ISO 17874 describes requirements concerning devices for remote handling of radioactive materials. The classification of these devices (categories and different designs within a category) and the distribution in the different parts are shown in Figure 1.

Concerning the working volume, two principal designs are to be considered.
  1. a) Fixed remote handling devices:
    these devices are fitted in the shielding wall or sometimes in the ceiling of hot cells and accordingly can function only in a rather limited volume. Such devices are mechanical master-slave manipulators and remote handling tongs.
  2. b) Mobile remote handling devices:
    these devices are fitted on a transporter (e.g. a moveable bridge or a vehicle on the ground). The working volume depends mainly on the possible motion of the transporter. Such devices are electrical master-slave manipulators and power manipulators.

NOTE This part of ISO 17874 is intended to provide assistance to designers of nuclear process plants, as well as manufacturers, users and licensing authorities.
