  9. Safety implications of a sensitivity analysis of the reactor kinetics parameters for fast breeder reactors

    Florian, Robert JosephVirginia Polytechnic Institute and State University1982

    The delayed neutron spectra for LMFBRs are not as well known as those for LWRs. These spectra are necessary for kinetics calculations which play an important role in safety and accident analyses. In this study, a sensitivity analysis was performed to study the sensitivity of the reactor power and …
