The quasi-static method has shown to be an efficient tool for the time-dependent analysis of nuclear systems allowing a significant reduction of the computational effort needed for fun space and energy transient calculations. The method is based on the factorization of the neutron density in the product of a shape and an amplitude function. The time integration of the balance equations is then carried out on a fast scale for the amplitude and on a much slower scale for the shape. Since the shape calculation is the most time consuming, this scheme allows a significant reduction of the computing time. In this work some specific features of the quasi-static technique are investigated, with special regard to the application of the method to source-driven systems.
