摘　　要：燃料稳态辐照装置用于研究堆开展不同燃料的堆内性能辐照试验。根据堆内水力测量试验和堆内物理测量试验分别确定了辐照装置在49—2堆稳态运行时的冷却剂流速和燃料棒线功率，以此对辐照装置进行了热工设计与分析，最终由堆内辐照试验加以验证。结果表明两者基本相符。The steady-state fuel irradiation rig is designed to conduct various fuel performance tests in research reactors. The coolant velocity along the fuel rods was determined through in-pile hydraulic test. The linear power of the fuel rods was determined through in-pile neutron flux measurement. Then thermal analysis and validation test for the irradiation rig were carried out in Swimming Pool Reactor （SPR） steady-state operations. It is shown that the measuring results are basically consistent with those of the thermal calculation.
