The elastic model for arbitrary radially cracked fuel implemented in COMETHE-4D
Description
Among high burnup effects, the swelling occurring in the pellet rim is such that the fuel presents a radial bridging in its periphery. This secondary bridging has an important effect on the mechanical reaction of the fuel in case of PCI. The present paper describes the elastic mechanical model of the fuel to be implemented in COMETHE-4D which alleviates problems encountered with the previously model which assumed such bridging to occur solely in the central part of the fuel.
