Abstract
  • In a Modular High Temperature Gas Reactor (MHGTR), the Pressurized Conduction Cooldown (PCC) event is an accident scenario in which there is a loss of forced convection of the coolant through the system but the pressure boundary remains intact. When the PCC event occurs, natural circulation onsets which results in a flow and temperature reversal, resulting in hot helium flowing into the upper plenum which could imping upon the upper plenum head. The High Temperature Test Facility (HTTF), which is being designed and constructed at Oregon State University, is a scaled thermal test facility of the MHTGR which is being built for both code validation purposes and to examine specific flow phenomena of the gas reactor. This study is being performed to determine how the HTTF simulates the same conditions as the MHTGR under this scenario through the use of scaling parameters and computational fluid dynamics.
