The neutron absorption sphere shutdown system is the second shutdown system of the 10MW High-temperature Gas-cooled Test Reactor. 7 sets of absorption sphere shutdown system equipment are verified on the 10MW high-temperature reactor. System parameters including sphere falling down time (60s), conveying time (200s), sphere level indicator, rose motor flowrate, and valves open-close state is acceptable. Test result indicates that the absorption sphere shutdown system can satisfy the technical requirements of 10MW high-temperature reactor.
