Systems Engineering and Safety


Systems engineering is an interdisciplinary field of engineering that focuses on how complex engineering projects should be designed and managed. According to different cases, the purpose and the scope of the study can be safety, reliability, economic performance of the system and so on.

As “an accident anywhere is an accident everywhere” in the nuclear industry, the nuclear safety has attracted more and more attention from the scientists, engineers and also the public. Systems Engineering and Safety Group’s (SESG) research goals are safety and economics of the nuclear energy. A series of software has been developed by this energetic, enterprising and innovative team. All of them have been successfully applied in the different specific fields, for example in the reliability analyses of ITER-TBM (International Thermonuclear Experimental Reactor Test Blanket Module), EAST (Experimental Advanced Superconducting Tokamak) and MAOD (Military Atmospheric Optics Device) etc.

Recently SESG is engaged in the development of TQRM (Third Qinshan nuclear power plant Risk Monitor), which is the first self-developed software being applied in the nuclear safety field of China.

Feature Projects


TQRM has been jointly supported by Commission of Science, Technology and Industry for National Defense and Third Qinshan Nuclear Power Company Limited (TQNPC). The instantaneous risk of the power plant could be monitored by using TQRM in order to keep the plant’s risk level under control. It can also help to demonstrate risk awareness to the nuclear regulatory authority. With TQRM the operation and maintenance cost could also be reduced significantly.


ITER is the largest international cooperation project up to now. The overall programmatic objective of ITER is to demonstrate the scientific and technological feasibility of fusion energy. Test Blanket Module is the most essential part of ITER device (for the heat removing, waste transmutation and fuel breeding). RiskA has been used for the reliability analysis of ITER-TBM. The analysis report has been submitted to the relevant organization.


EAST is a large-scale scientific facility supported by the national government. It is a complex system consisting of thousands of components. Reliability analysis of EAST has been carried out by SESG. Some design, operation and maintenance advice has been given based on the analysis conclusion.


The reliability and safety of MAOD, which is a military device, should be especially concentrated on. Fault Tree Analysis has been used on MAOD and some advice has been given to enhance the device’s reliability and safety.
