Abstract

The Pu/MA ratio determines the transmutation rate and the burn-up characteristics. The initial reference value is taken as Pu/MA = 46/54 at%. Then it is reduced down to 35/65 at% for optimizing the reactivity swing and the MA transmutation efficiency. The effect of reduced Pu/MA ratio on the reactivity needs to be compensated by increasing the fuel volume fraction, which can be realized by reducing the pin number per SA and increasing the pin diameter. It is shown that the original coolant/clad thermal hydraulic conditions can be preserved, as the pin number is reduced and the fuel volume is increased. A good transmutation efficiency and an almost zero reactivity swing have been achieved by a 61-pin arrangement with Pu/MA = 35/65 at%.
