Abstract
In a nuclear reactor comprising control rods, nuclear fuel elements each having a cladding and pellets inserted therein, and a recirculation system, the reactor raises its power at least once by withdrawal of the control rods above a pellet-cladding interaction starting power (kw/ft) of the fuel element in a burnup range below the burnup at which the maximum pellet-cladding interaction starting power appears.
