China General Nuclear Power Corporation (CGN) and its subsidiaries were recently granted a number of awards by the Chinese Society for Electrical Engineering for their achievements in technology development.
The “load protection method and system of nuclear fuel upending device” developed by CGN won the third prize of the China electric power science and technology invention awards for 2017. The upending device, one of the key components of the nuclear fuel transfer device in a pressurized water reactor (PWR) nuclear plant, can tip over the fuel basket and assemblies during the refueling process. The awarded technology reduces the risk of fuel components being bumped.
China Nuclear Power Engineering Co Ltd won the second prize of the China electric power science and technology progress award for 2017 with the project “R&D and application of the design and production platform for nuclear power systems”. Reaching to a world advanced level, the project effectively improved system design efficiency and has been employed in many engineering projects.
Another project that won a second prize of the progress award for 2017 was the “design and construction of the on-line monitoring and defense system for the thermal fatigue of primary coolant circuit safety injection pipelines” of the CGN Research Institute. This was the first independent improvement in China of the thermal fatigue of primary loop safety injection pipelines. It helped Daya Bay Nuclear Power Plant save 40 million yuan ($6.30 million) in design and construction costs and made the plant safer and more reliable.
Several other projects won the third prize of the 2017 awards, including the “loss of power analysis and emergency operation procedure study for cold function tests under the concept of ‘defense-in-depth’” of China Nuclear Power Engineering Co Ltd, “study on mechanism and control of power oscillation in generators and power grids caused by main transformer transmission” of Daya Bay Nuclear Power Operations and Management Co Ltd, and the “independent accomplishment of automatic wielding and replacement of primary loop valves in operating nuclear power plants” and “development and application of severe accident simulators at Daya Bay Nuclear Power Bases” of China Nuclear Power Operations Co Ltd.
Individuals who made contributions to scientific and technological innovation were also awarded by the Chinese Society for Electrical Engineering. Sun Qi from China Nuclear Power Engineering Co Ltd, Lv Yonghong and Rui Min from the CGN Research Institute were honored as “China Power Outstanding Scientific and Technological Workers”, and Wang Jiantao from China Nuclear Power Operations Co Ltd, Zhu Decai from China Nuclear Power Engineering Co Ltd, and Li Jianbo from CGN Research Institute won the “China Power Outstanding Young Engineer Award”.
