Keywords:Resonance calculation, Reduced order model, Low rank approximation, Ultra-fine group spectrum

A new theory for a resonance calculation method is discussed. In this method, energy expansion bases, which are obtained by the reduced order model and the low-rank approximation for ultra-fine group neutron spectra, are used.
