“…Though the work done by Brady and England has played quite an important role in this field, a problem of their evaluated parameters has been pointed out by some authors [5,6]. While the widely used delayed neutron parameters evaluated by Keepin yields consistent results with experimental data for the reactor kinetic behavior, some deficiencies have been observed when Brady and England's data are used.…”

In order to better predict the kinetic behavior of a nuclear fission reactor, improvement of delayed neutron parameters is essential. Since it is required to establish a path from the microscopic nuclear data to the macroscopic delayed neutron parameters for the improvement, the present paper identifies important nuclear data for reactor kinetics. Sensitivities of the reactor stable period, which describes reactor kinetic behavior, to microscopic nuclear data such as independent fission yields, decay constants and decay branching ratios are calculated efficiently by using the adjoint kinetics equation. Furthermore, nuclide-wise and nuclear data-wise uncertainties of the reactor stable period are quantified using the variance data given in the nuclear data file, and the nuclear data that require further improvement are identified. The results obtained through the present study are quite helpful, and can be a driving force for further nuclear physics studies.

This paper demonstrates that it is well possible to determine the kinetic parameter P,E/A in a neutronically very slow system by means of noise measurements in the critical state. The advantages of this technique are that it can be conducted in a critical reactor directly, and that no special measurement equipment is needed. The comparison to calculated values for four configurations, which differ in the amount of moderation in the core region, shows a satisfactory agreement.
