Abstract

The prismatic modular reactor (PMR) is one of the leading designs for the next generation of nuclear reactors because of its ability to passively remove heat by convection in an accident scenario. It is important to understand how the coolant, helium, circulates in order to design reactors that safely shutdown in the event of a loss of coolant flow accident. We studied the effect of the outer surface temperature of the reactor vessel on the circulation of the helium and the transfer of heat within the reactor. A scaled down duel-channel facility was used to study the plenum-to-plenum circulation. Data was taken with one channel heated, and the other channel and the upper plenum cooled to different temperatures. The temperature and heat flux was measured at several points along the channels.
