In order to perform LLFP nuclear transmutation by a high intensity deuteron beam safely, stably and efficiently, a conceptual design of a relatively-compact multiple cyclotron system is presented. Technical issues for increasing beam intensity and improving energy efficiency will be clarified and configuration of a high power, low cost cyclotron system will be discussed.
