Robotic systems that enable the operators to remotely manipulate delicate materials with high dexterity and sufficient force feedback will pave the path for improvements of the safe maintenance and decommissioning processes within the nuclear industry. Training the operators, however, for challenging conditions (e.g., low visibility, restricted motions in the confined spaces, limited interaction force) in a time- and cost-effective manner is difficult. This paper proposes possible application areas of a haptic training simulation platform that can prepare the operators to remotely manipulate hazardous materials more economically by simulating different tasks, robots, and their surroundings in the hazardous environment. The proposed use cases within the nuclear industry for such simulation platform varies from the post-operational clean-out process to operations in the contaminated environment after a disaster.
