The loss of forced cooling (LOFC) tests have been carried out by Japan Atomic Energy Agency (JAEA) using the High Temperature engineering Test Reactor (HTTR). In order to demonstrate safety feature of the High Temperature Gas-cooled Reactors, helium gas is decreased to zero without reactor power control by control rods.
In this study, reactor power and reactivity are evaluated by changing coolant flow rate in the LOFC tests. A reactor kinetics analysis code called the TAC/BLOOST code is used in the analysis.
