Description
Neutron sources are the important experimental platform for the R&D of advanced nuclear energy systems, especially for the development for fusion systems. Series High Intensity Steady Neutron Sources (HINEG), comprising three phases(HINEG-I, HINEG-II, and HINEG-III), have been developed in China for different missions including neutronics design validation, materials & components irradiation test, nuclear waste burning and nuclear technology applications, etc. This contribution reports on the recent progress and status of HINEG projects.
HINEG-I , which has already operated, is a D-T fusion neutron source with the yield of 6.4×1012 n/s, and has been coupled with the Lead-based Zero Power Reactor CLEAR-0. It can provide neutrons exactly the same with fusion reactors. Series experiments have been carried out on HINEG-I, including neutronics performance test of TBM blanket, measurement of leakage spectra from Pb and Pb-Bi, irradiation damage testing for laser crystal, etc.
HINEG-II includes two sources, HINEG-IIa and HINEG-IIb. HINEG-IIa is a high-voltage electrostatic accelerator-based D-T neutron source with neutron yield over 1013n/s. HINEG-IIb is a cyclotron-based spallation neutron source with neutron yield more than 1014n/s. These two sources are aimed to provide multi-type of neutron spectrum including fusion-like neutron spectrum and high neutron intensity for radiation damage mechanism study, advanced reactor technology validation, and extended nuclear technology application research, etc. The construction and assembly of the two sources of HINEG-II are on-going.
HINEG-III is high flux steady state neutron source with the intensity of 1017-1018 n/s. It will be coupled with a subcritical reactor with neutron flux higher than 1015 n/cm2/s. HINEG-III is a multi-purpose neutron irradiation platform for irradiation testing of fuel, material and components for advanced reactors. The conceptual design of HINEG-III is on-going.
HINEG is an open platform to provide high intensity neutron beams. We sincerely welcome all kinds of cooperation and participation from affiliations and colleagues all over the world.
