Abstract
China Institute of Atomic Energy (CIAE) is one of the most important bases for nuclear data measurement in China. In this paper, the nuclear data measurement activities at CIAE in recent years are presented. The secondary neutron emission DX and DDX measurement, the integral experiment for nuclear data benchmarking, the excitation function measurement, the neutron induced fission yields measurement and the gamma production yields measurement carried out in recent years are introduced. Furthermore, the progress of some new facilities and proposed plans (e.g. A Gamma ray Total Absorption Facility (GTAF) for (n,γ) reaction cross section measurement, A 3 He detector array for (n,2n) reaction cross section measurement, the back streaming white neutron beam for nuclear data measurement at China Spallation Neutron Source (CSNS)) are also presented.
Highlights
The goal of nuclear data activities in China is supplying the nuclear data to feed the needs of the nuclear energy development, nuclear science study and nuclear technology applications
The facilities used for nuclear data measurement and study include the HI-13 tandem accelerator, 600 kV-Cockcroft-Walton accelerator and 5SDH-2 2 × 1.7 MV tandem accelerator
A white neutron source beam line [3, 4] based on China Spallation Neutron Source (CSNS) will be available mainly for nuclear data measurement at that time
Summary
The goal of nuclear data activities in China is supplying the nuclear data to feed the needs of the nuclear energy development, nuclear science study and nuclear technology applications. China Institute of Atomic Energy (CIAE) is one of the most important bases for nuclear data measurement in China. The facilities used for nuclear data measurement and study include the HI-13 tandem accelerator, 600 kV-Cockcroft-Walton accelerator and 5SDH-2 2 × 1.7 MV tandem accelerator. The China Experimental Fast Reactor (CEFR, 65 MW) reached critical on 21 June 2010, and China Advanced Research Reactor (CARR, 60 MW, the maximum neutron flux: 8 × 1014 n/cm2· s) reached critical on 13, May 2010 at CIAE, were used for nuclear data related research. A white neutron source beam line [3, 4] based on CSNS will be available mainly for nuclear data measurement at that time. The nuclear data measurement activities at CIAE in recent years are presented, and the progress of some new facilities and proposed plans are given
