    Abstract

    The divertor area of ITER Vacuum Vessel (VV) consists of 54 modular cassettes which must be replaced three times during the estimated 20 years of operation of the ITER. Cassette Multifunctional Mover (CMM) and Cassette Toroidal Mover (CTM) are used in the cassette remote handling (RH).

    In this paper we discuss the design and development process for the RH equipment to be used in the ITER environment. Design concepts for the Standard Cassette End-Effector and Central Cassette End-Effector are described and the conceptual design phase methodology is presented.

    The main improvements of the new End-Effector concept designs are more robust and reliable assembly process with reduced CMM mover assembly accuracy requirement. New Central Cassette locking system was developed to address the high forces and contact pressures emerging during the Central Cassette installation. The chosen design concepts are verified with virtual reality simulations and are fulfilling the requirements defined in the concept design phase, including structural, assembly sequence, safety and reliability.
