It is reported that after completing the high-speed dynamic balance test of the first nuclear power medium and medium pressure rotor and the first nuclear power low-pressure rotor of the independent design and manufacture of the nuclear "Hualong No.
1" steam turbine last year, Dongfang Electric Group Dongfang Steam Turbine Co.
, Ltd.
completed the high-speed dynamic balance test of the second low-pressure rotor of the first steam turbine of "Hualong No.
1" (Unit 5 of Fuqing Nuclear Power Plant) on the afternoon of March 6, marking the successful
development of all the steam turbine rotors of the world's first reactor demonstration project of China's independent third-generation nuclear power "Hualong No.
1".
According to the relevant person in charge of Dongqi, the low-pressure rotor weighs 281 tons, the test is difficult and demanding, in the rotor high-speed dynamic balance test, the tester makes full use of years of test experience and historical data to carefully analyze, and constantly solve the new problems that arise, and finally completed the test within one day, the vibration value is much less than the standard and technical protocol requirements
.
"Hualong No.
1" nuclear power technology is a million-kilowatt-level pressurized water reactor nuclear power technology developed by China National Nuclear Corporation and China General Nuclear Power Group, which is a major achievement
of China's independent innovation in nuclear power.
CNNC Fuqing Unit 5 and Unit 6 project is the world's first demonstration project
of "Hualong No.
1".
Dongfang Electric is responsible for the design and manufacture
of the main equipment such as the nuclear island steam generator and the conventional island steam turbine generator set of the first reactor of the "Hualong No.
1".
The design of conventional island steam turbine engine has been established since 2007, with completely independent intellectual property rights, passed the acceptance of the national expert group in 2012, and was approved
by the Fuqing nuclear power project in 2015.
The development of the "Hualong No.
1" conventional island steam turbine for nuclear power has laid a solid foundation
for the grid-connected power generation of the first unit of "Hualong No.
1".
