For power uprate of Pressurized Water Reactor(PWR), a dual-cooled annular fuel is being developed in Korea Atomic Energy Research Institute(KAERI). The annular fuel rod is configured to allow the coolant flow through the inner channel as well as outer channel. Since the inner channel is isolated from the neighbor channels unlike the outer channels, an inner channel blockage is one of the principal technical issues of a dual-cooled annular fuel.
As a hypothetical event, if the inner channel is completely blocked by the debris, the inner cladding may experience a rapid temperature increase because of no further coolant supply. To complement the entrance blockage of an inner channel a long end plug with side holes is conceptually suggested. The experiment is performed to estimate the flow rate through side holes at the side hole blockage event. In this paper, the inner channel flow rate by the side holes was measured and the loss coefficient of side holes was evaluated.
