Development of divertor cassette locking tool prototypes according to remote handling requirements

Abstract

Engineering Development is one stage from the huge development method called Systems Engineering. In this Thesis, Engineering Development is studied and applied for two Case studies. The main emphasis is on the Requirements Management, Design and Testing. Two Remote Handling (RH) capable tools are developed in the case studies: Water Hydraulic Jack (WHJ) and Wrench-Pin Tool (WPT). WHJ is developed from the first prototype and WPT is developed from a concept level. The tools are used remotely for Gradel Cassette locking and unlocking processes by a robot called Water Hydraulic MANipulator (WHMAN) at Divertor Test Platform 2 (DTP2). The Gradel Cassette is a full scale Mock-Up from a Divertor Cassette that will be used in the International Thermonuclear Experimental Reactor (ITER). The RH specific Requirements are developed by gathering Operator Feedback (OF), performing Potential Problem Analysis (PPA) and Task Description (TD) for the locking process. The Divertor Cassette Locking Tools are designed according to these RH specific requirements. After the design process, the tools are tested in a full scale test environment and the RH requirements are verified. The development and testing procedure that is performed for the RH tools may be used as a guideline for forthcoming new generation Divertor Cassette Locking Tools.
