en.Wedoany.com Reported - On May 16, the low-pressure cylinder rotor of the steam turbine was successfully reinstalled in one attempt during the OT116 overhaul of Unit 1 at the Jiangsu Tianwan Nuclear Power Plant, a project undertaken by Anhui No.2 Electric Power Construction Co., Ltd. of China Energy Engineering Group.

The low-pressure cylinder rotor of the steam turbine is approximately 7.5 meters in length and weighs about 82 tons, and was hoisted using a 250-ton overhead crane.

During the rotor reinstallation process, the maintenance team members had clear division of labor, closely monitored the rotor's levelness and lateral displacement, and promptly adjusted the rotor's movement amount and center position. The entire reinstallation work proceeded in an orderly manner and was ultimately successful in one attempt. The successful reinstallation of the low-pressure cylinder rotor has laid the foundation for the smooth startup of the subsequent unit.

The Tianwan Nuclear Power Plant is located in Lianyun District, Lianyungang City, Jiangsu Province. The company is responsible for the overhaul and routine maintenance of the conventional islands for Tianwan Nuclear Power Units 1-4, routine BOP maintenance for Units 1-6, instrumentation and control maintenance for the conventional islands of Units 7 and 8, as well as routine maintenance and overhaul projects for "Heqi No.1".
