شبیه سازی و آزمایش سیستم مدیریت سوخت برای راکتور باکتریایی راننده شتاب دهنده

For the fuel handling in Accelerator Driven Subcritical Reactor (ADSR), some key issues should be considered, such as the accelerator proton beam tube blocking, the liquid metal corrosion and the radiation. As a critical part of the reactor, the innovation design of the double rotating plugs and split-type center column scheme of the Fuel Handling System in the vessel was proposed according to the features of ADSR. A location computation model for the computer simulation was established based on the system. Through the comparative analysis between the numerical simulation results, the proposed structure is optimized and the operating range of the system can completely cover the refueling operation range of the core. Then, a principle prototype in air condition has been developed and tested. The simulated automatic refueling that covering all assemblies was realized on the prototype.
