The Operation Characteristics of the Fuel Handling System of HTR-10

10 MW High Temperature Gas-cooled Reactor (HTR-10) is a pebble bed reactor, helium serves as the coolant, the fuel element is spherical, and its diameter is 60 mm. In power operation, the reactivity of HTR-10 is almost kept in a constant, because the fuel elements could be loaded, discharged and reloaded online, all these processes referred above are carried out automatically by the fuel handling system. In this paper, the operation characteristics of the fuel handling system, including the features of some special equipments, three automatic processes of fuel elements handling, the configuration and operation features of the control system and the operation conclusion in these years since 2000 are introduced.
