Intensive research and development activities have been conducted for preliminary design of a water-cooled ceramic breeder (WCCB) blanket system. As a part of these activities, some full scale mockups have been fabricated to verify feasibility, including manufacturing and inspecting procedures. This paper introduces an overview of the recent achievements in the mock-up testing on the WCCB blanket system. A blanket sub-module mockup have been manufactured using a reduced activation ferritic/martensitic steel, F82H with conventional industrial resources. As for water cooling system component, a mock-up of pneumatic isolation valve for DN50 pipe. The valve demonstrated sound operation after vertical and horizontal vibration simulating seismic loads. Moreover, the valve has demonstrated close / open operation in less than three seconds in magnetic field ranging from 290 to 500 mT, and the operation time was not affected by the magnetic field in this range. As for tritium storage device, mockup of ZrCo metal hydrate bed were also manufactured to find show stoppers in application as equipment for tritium extraction system (TES) in the WCCB-blanket system. |
