China's first CAP1400 nuclear power plant depleted uranium main pump flywheel was successfully developed

Recently, the first set of CAP1400 nuclear power plant depleted uranium main pump flywheel in China was assembled in CNNC North Nuclear Fuel Components Co.
, Ltd.
, and after dynamic balance test, it fully met the design requirements
.
As a key component supporting the motor of the third-generation large-scale advanced pressurized water reactor shielded pump independently developed in China, the achievement has completely independent intellectual property rights, and its successful development improves the safety and reliability of flywheel and main pump operation, and further expands the application of
depleted uranium materials in the nuclear power industry.

It is understood that the development of the depleted uranium main pump flywheel of CAP1400 large-scale nuclear power plant belongs to China's major scientific research project, and it is the first time that the main pump flywheel of China's nuclear power plant uses depleted uranium materials to carry out the preparation technology research
.
The project was undertaken by CNNC North and lasted for two years, breaking through many technical problems such as material selection, casting technology, heat treatment, machining, and assembly, and finally successfully achieved development
.
