Concept of Contamination Control Door for DEMO and Proof of Principle Design

During the maintenance period of a future fusion reactor power plant, called DEMOnstration Power Plant (DEMO), remotely handled casks are required to confine and handle DEMO in-vessel components during their transportation between active facility. In order limit dispersion activated dust, Contamination Control Door (CCD) is designed be placed at an interface separable containments (e.g., vacuum vessels casks) inhibit release contamination them. The operated CCD—technically, double lidded door system—consists two doors (the cask port door) three different locking mechanisms: (i) cask, (ii) (iii) port. mechanisms selected assessed according criteria, structure CCD optimized using Abaqus Topology Optimization Module. Due elastic properties CCD, deflections will occur lifting procedure, which may lead malfunctions CCD. A test rig developed investigate performance high-risk in case also malpositioning. Misalignment can induced along axes angles intentionally single items. aim identify possible range operating misalignments. It expected that proposed design should able operate appropriately ±3 mm translational misalignments ±1° rotational
