CFD Investigation of MHTGR Natural Circulation and Decay Heat Removal in P-LOFC Accident
Frontiers in Energy Research, 2020 One of the key postulated accidents in a high-temperature gas-cooled reactor (HTGR) is the pressurized loss of forced cooling (P-LOFC) of the primary loop, which can be triggered by its primary helium circulator trip or turbine trip.
