At 12:52 on February 20, the turbine generator of Unit 1 of China's San'ao Nuclear Power Project was rolled up to the rated speed and operated stably, marking the successful completion of the first nuclear steam turbine rolling test for Unit 1. This has laid a solid foundation for subsequent commissioning, grid connection, and commercial operation of the unit.
The nuclear steam turbine rolling test is a critical step to verify the mechanical and thermodynamic performance of the turbine generator set, ensuring its installation quality and operational reliability. This test verifies the reliability of the main steam pipeline and related equipment, providing a solid guarantee for subsequent safe grid connection and full-power operation.
During the rolling process, the unit sequentially performed various tests. The turbine speed steadily increased to the rated platform of 1500 rpm and achieved stable operation. All systems and auxiliary equipment maintained good operating conditions, and all technical indicators met the procedures and design standards.
Prior to the test, the production engineering commissioning and startup team refined emergency response plans for the entire test process, developed a detailed commissioning and startup plan, and clarified operational specifications, division of responsibilities, and risk prevention and control measures for each step. Various professional personnel conducted on-site surveys in advance, performing multiple rounds of verification and calibration on turbine instruments, systems, and related equipment, striving to ensure the unit was in optimal condition for the test and building a solid safety and quality defense line for the rolling test.
The success of the first nuclear steam turbine rolling test is a crucial step in the high-quality commissioning process of Unit 1 of the San'ao Nuclear Power Project. It signifies the first nuclear-linked operation between the nuclear island and the conventional island, marking a major milestone as the unit transitions from the construction phase towards grid-connected power generation.
