Beta-delayed neutron emission is important for nuclear structure and astrophysics as well reactor applications. Significant advances in experimental techniques the past two decades have led to a wealth of new measurements that remain be incorporated databases. We report on coordinated effort compile evaluate all available ?-delayed data. The different measurement been assessed data compared wit...

In nuclear fission, a delayed neutron is a neutron emitted by one of the fission products any time from a few milliseconds to a few minutes after the fission event. The counts of delayed neutrons constitute a time series sequence. The analysis of such time series can prove to be very significant for purpose of predictive maintenance in nuclear power plants. In this paper we aim to identify anom...

The fraction of delayed neutrons in a moderated beam from the enriched uranium, pulsed spallation source at the intense pulsed neutron source at Argonne National Laboratory has been measured and found to be 0.0283 for 450-MeV protons. Delayed neutrons produce a sample-dependent background in time-of-flight instruments . Because of the distribution of neutron wavelengths in the prompt pulse, the...

The neutron long counter NERO was built at the National Superconducting Cyclotron Laboratory (NSCL), Michigan State University, for measuring b delayed neutron-emission probabilities. The detector was designed to work in conjunction with a b delay implantation station, so that b decays and b delayed neutrons emitted from implanted nuclei can be measured simultaneously. The high efficiency of ab...

The neutron density is one of the most important dynamical parameters in a reactor. It is directly related to the control and stability of the reactor power. Any change in applied reactivity and some of dynamical parameters in the reactor causes a change in the neutron density. Lyapunov exponent method is a powerful tool for investigating the range of stability and the transient behavior of the...
