“…1, the system is consist of top jig and inboard (outboard) jigs, the inboard (outboard) hydraulic cylinders play a supporting role. Due to the system bears dozens of tons of blanket, affects the motion reliability directly and requires high synchronization accuracy, it requires three cylinder piston rods have same speed at any time and transfer the blanket to the upper window smoothly [2]. For general synchronization system, measure synchronization movement performance is depends on synchronous precision.…”

The remote handling operations of the China fusion engineering test reactor blanket is highly challenging since the tasks performed by the water hydraulic manipulator, which is made up of three hydraulic cylinders, involve driving up, synchronous controlling and transporting from inside the vacuum vessel. The blanket is made of stainless steel, high 7 m and weigh 60 t, which makes the assembly and maintenance more difficult. A general synchronization control system cannot be used due to its poor stability and low precision in the heavy duty working process. Therefore, to achieve higher precision in controlling of three hydraulic cylinders, one of the most suitable options should be provided. This paper studies the control of synchronous system, besides, it also discusses an effective way to improve synchronization accuracy by use AMEsim. The results of simulations demonstrates that insert the low-pass filter in control loop can be utilized to improve the precision of manipulator.

“…The mainly purpose of CFETR is to test the related fusion technology and engineering in fusion power plant, especially long pulse or steadystate operation with envisioned duty cycle time at the range of 0.3-0.5 and exploring option for DEMO blanket & divertor with easy changeable in-vessel components by remote handling equipment [1][2][3][4] (Fig. 1).…”

“…During the maintenance period divertor cassette removed from the host by the divertor remote handling system CMM and CTM tools [4], it will be conveyed into docking station by TB Cask and then cleaned by preliminary clean station with dry ice blasting to dispel radioactive particles, later through an air lock chamber transferred by the intermediate cask into the divertor maintenance cell to complete rest of the maintenance process. …”

“…According to the design requirements, CFETR should be a good complement to ITER. It will demonstrate the fusion energy with a fusion power of 50-200 MW and long pulse or steady-state operation with duty cycle time 0.3-0.5; demonstrate the full cycle of tritium selfsufficiency with TBR ≥ 1.2 [1,2]. As we know, the ITER RHMS design is in progress and the RHMS development strategy for blanket and divertor in both ITER and DEMO should be considered in a simple and efficient way [3,4].…”

“…The availability and reliability of the divertor remote handling maintenance system (DRHS) and the high compatibility of the reactor maintenance are the most important factors which should be taken into consideration for CFETR maintenance. Therefore, we should avoid complex operations in the vessel and reduce complexity of the DRHS design [2][3][4]. The main differences of the divertor features between CFETR and ITER are the segmentation changed from 6.66 • to 9 • and more neutron shielding function added on the cassette body.…”
