Eigenvalue spectrum of the operator for a model of developing nuclear power

An approximate model of a fuel cycle of a developing nuclear power using fuel-exchanging thermal and fast reactors is discussed. A model of steady fuel circulation is analyzed; the model does not take account of the delay in an outer cycle. Results are given of calculations of eigen value spectrum of the matrix operator which corresponds to the model under study at different rates of fuel exchange between fast and thermal reactors and at various feedings of fast reactors from blankets
