The Ordered Bed Modular Reactor (OBMR) is an advanced modular HTGR design in which the annular reactor core is filled with an ordered bed of fuel spheres. This arrangement allows fuel elements to be poured into the core cavity which is shaped so that an ordered bed is formed and to be discharged from the core through the opening holes in the reactor top. These operations can be performed in a shorter shutdown time.
The core of the OBMR as a pebble fuel core has great structural flexibility and stability. It is allowed to increase reactor output power and decrease core pressure drop as well as having most of the advantages of both the pebble bed reactor and block type reactor. This paper introduces ordered packing bed characteristics and predicted design features of the OBMR.
