Proc. ASME. ICONE21, Volume 2: Plant Systems, Construction, Structures and Components; Next Generation Reactors and Advanced Reactors, V002T03A025, July 29–August 2, 2013
Paper No: ICONE21-15511
... The absorber ball shutdown system is a key system and related to reactivity control in HTR-PM, which has once achieved power regulation and cold shutdown of the nuclear reactor. Passive drive mechanism of absorber ball shutdown system has been designed for HTR-PM reactor safety before. Ball...

Proc. ASME. ICONE21, Volume 4: Thermal Hydraulics, V004T09A002, July 29–August 2, 2013
Paper No: ICONE21-15015
... A large amount of graphite blocks were served as the construction material, the neutron reflectors and also shaped as several helium flow paths in the HTR-PM reactor core. A majority of helium flowed through the pebble bed to bring out the huge fission heat, while a minority might flow in...

Paper No: ICONE21-15559
... Control rod drive mechanism is very important to the operation and safety of reactors, therefore, requiring good mechanical properties and a high degree of reliability. The control rod drive mechanism of high-temperature-reactor pebble-bedmodule (HTR-PM) is powered by permanent magnet stepping...

Paper No: ICONE20-POWER2012-54045
... Many graphite blocks in the core of the HTR-PM serve as the construction material, the neutron reflector and the flow paths of the helium. A small part of helium gas may flow in widely distributed gaps among graphite blocks and enter the hot plenum at low temperature. In our previous paper, a...
