In this work a new approach to the realization of an Accelerator Coupled hybrid System (ACS) is proposed. A significant improvement of the feedback effect due to the particularities of the neutron production in a spallation target is expected. In a present study we explain the principle of the system functioning, advantages and disadvantages of the proposed concept. The quantitative analysis of the innovative ACS operation is based on a generalized point kinetics approach. In the frame of this simplified model we show that the particular dependence of the spallation neutron yield allows creating a supplementary negative feedback effect (Doppler-like). The implementation of this concept should compensate, at some extent, eventual feedback degradation in the cores dedicated to transmute nuclear waste. |
