The main research results

1)Helium turbine cycle in HTGRs:

We performed the theoretical and experimental studies on the closed Brayton cycle and its key components, paving the way for the future development of nuclear gas turbine power systems. We designed power conversion system based on closed Brayton cycle for 10MW high-temperature gas-cooled (HTR-10) and commercial HTGR. We accomplished the design, manufacture and test of helium compressors and helium turbine. We are also developing the gas turbine power generation system for mobile micro-reactor and space reactor.

2)Development of helium circulator for HTGRs:

With the support of major national science and technology projects, we have developed the world's first high-power electromagnetic bearing helium circulator engineering prototype, making breakthroughs in the helium circulator integration technology, three-dimensional high-efficiency impeller design and manufacturing technology, both active and passive functional circulator baffle technology and many other major key technologies. 12 invention patents has been authorized. This achievement is a major breakthrough in mycountry's independent innovation in advanced nuclear energy core equipment technology. The helium circulator using domestic electromagnetic bearings has completely independent intellectual property rights. The achievement has been applied in high-temperature gas-cooled reactor demonstration projects and subsequent multiple high-temperature gas-cooled reactors. In engineering projects. The helium circulator technology has reached the world's leading level and was rated as one of the "Top Ten Scientific and Technological Progress in China’s Higher Education Institutions" by the Ministry of Education in 2014.

4)Research on the behavior of graphite dust:

Studying the behavior of radioactive graphite dust under accident conditions is of great significance for the nuclear safety analysis of HTGRs. We studied the entire process of graphite dust particle generation, deposition and diffusion, agglomeration and collision, accidental emissions. We proposed an experimental method of "combination of vibration signals and visualization" to establish a dynamic model of collision and wear of spherical fuel elements, and revealed coherent structure and dust transport mechanism under large temperature gradient, developed the "moment-distribution" coupling solution method of particle evolution, established the "rough wall-particle" adhesion model, and developed a single-layer/multi-layer particle resuspension model and methods for assessing accidental releases of radioactive dust. The research results were successfully applied to the nuclear safety review of my country's high-temperature gas-cooled reactor national demonstration project HTR-PM, and won the Youth Particle Science Award and the second prize of the Natural Science Award of the Chinese Particle Society.
