Preliminary Design Review on a Transfer Trolley of Large Structures in a Hot Cell

In a hot cell the irradiated materials from reactors are handled to perform post irradiation experiments. The inside environmental conditions are very poor, with high radioactive and no direct access. Despite this conditions, a transportation device is necessary to move radioactive structures which are large and heavy over 50 tons in weight and 30 m3 in volume. Considering poor operating conditions a transportation device is required to be a simple structure and a passive system to minimize failure occurrences during operation. A trolley is preliminary invented to transport large radioactive structures in hot cells. It is steel cable driving type pulled by a winch set installed outside the hot cells. It is concise and easy to maintain and has a maximum capacity 70 tons including its own weight. In this paper mechanical, electrical, and control specifications for a trolley are preliminary reviewed
