As the astrophysical environment of the process and the relevant nuclear physics data far from stability are still questioned; more efforts for the astrophysical observation, simulation and radioactive beam experiment are needed. Among the nuclear physics data for r-process, beta-decay half-life determines the speed of the process, while beta-delayed neutron emission affects the late stage neutron recapture and detours the beta-decay chain back to stability. The BRIKEN project, an experimental program at the Radioactive Isotope Beam Factory (RIBF), will survey those decay parameters for the most neutron-rich nuclei which are responsible for the formation of the r-process abundance pattern. Within the project, a high and flat efficiency neutron counter array and highly segmented implantation detector are employed to take advantage of the intense RI beam produced by RIBF. In this report, an overview of the BRIKEN project will be presented. The impact of the specific beta-delayed neutron emitters, which are proposed to be measured, will be also clarified.
