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.

Analysis on inadvertent operation of decay heat removal system in NuScale reactor [PDF]
AIP Conference Proceedings, 2019 Analysis on inadvertent operation of decay heat removal system in NuScale reactor has been carried out through numerical simulations using the RELAP5 code. The model used includes primary system, secondary system, decay heat removal system (DHRS) and water pool. Simulation begins with an opening of single DHRS train isolation valve when reactor runs at
