EU-DEMO should demonstrate the technical as well as the economic viability of future fusion power plants. To reach the implemented goal of a sound availability also remote maintenance has to be performed fast and highly reliable.
During regular maintenance of the DEMO tokamak fusion reactor, all blanket segments, cooling and breeder pipes, divertor cassettes and other vessel inventory have to...
China has long been actively performing the integrated studies not only on R&D for ITER, but on the future fusion reactor. Institute of Nuclear Energy Safety Technology (INEST), Chinese Academy of Sciences (CAS) concentrates on the nuclear technology and safety, especially related to innovative fusion reactor/blanket concepts, neutronics simulation and experiments, materials and blanket...
On July 22, 2016, the NSTX-U project team suspended plasma operations due to the inoperability of the PF1A Upper (PF1A-U) coil. Preliminary indications evidenced that the PF1A-U coil experienced a coolant blockage. An external coolant leak developed from the PF1A-U coil pack after the blockage was attempted to be cleared. A post-mortem physics analysis indicated that an undetected gradual...
Extensive nuclear analysis has been performed for ITER fusion device in order to determine the shielding requirements to minimize radiation exposure to operational personnel and sensitive equipment. The radiation exposure evaluation has been focusing on the areas in which personnel access is anticipated for planned maintenance, such as in the port interspace for diagnostic systems. This...
Robotic remote operations are commonly used to conduct necessary work such as maintenance, decommissioning and experimental reconfiguration in environments that are hazardous to humans. This is especially prevalent within the nuclear fusion world, where devices such as JET, ITER , DEMO, and CFETR do or will require the remote execution of robotic remote operations of significant number and...
