Abstract: According to international experience at design and operation of similar systems, the reducer, the failed fuel separator, the elevator and the control system of the fuel handling system(FHS) in 10 MW high temperature gascooled reactor(HTR10) are improved so that the system becomes simpler and more reliable. The improved components are tested in fullscale testing facilities. The debugging test and the first loading operation for the FHS indicate that the FHS meets the demands of the HTR10.
