Using the Jacobi–Davidson method to obtain the dominant Lambda modes of a nuclear power reactor

Abstract: The Jacobi–Davidson method is a modification of Davidson method, which has shown to be very effective to compute the dominant eigenvalues and their corresponding eigenvectors of a large and sparse matrix. This method has been used to compute the dominant Lambda modes of two configurations of Cofrentes nuclear power reactor, showing itself a quite effective method, especially for perturbed configurations.
