Zhejiang Jinqimen Nuclear Power Unit 1 Pressurizer Relief Tank Successfully Hoisted into Place
On August 30, the pressurizer relief tank, a major nuclear island equipment item of Unit 1 at Zhejiang Jinqimen Nuclear Power Plant, contracted by China Nuclear Industry Fifth Construction Co., Ltd. (CNF), was successfully hoisted into place. The entire hoisting process was smooth and orderly, with overall safety and quality under control. This hoisting has laid a solid foundation for the subsequent installation of main nuclear island equipment and the construction of the primary loop system. The pressurizer relief tank is an important auxiliary equipment of the reactor coolant system in a nuclear power plant. Its main function is to collect and condense the high-temperature and high-pressure steam discharged from the pressurizer safety valves, ensuring the safe and stable operation of the reactor system. The relief tank hoisted this time is pre-installed equipment in the nuclear island. The main body of the equipment is heavy in weight and large in size, with limited hoisting workspace. After being hoisted into place, it needs to be placed in the nuclear island building for a long period, and subsequent construction will be constrained by space, making it necessary to introduce the equipment precisely within the civil construction window period.

Qinshan Nuclear Power Plant Unit 2 Outage 218 Officially Commences
At 2:20 AM on September 1, Unit 2 of Qinshan Phase II was disconnected from the East China Power Grid, marking the official commencement of Outage 218. This outage is a Category C overhaul for Unit 2 of Qinshan Phase II. In addition to the routine annual overhaul items such as reactor coolant system head removal and installation, fuel handling, SG eddy current inspection and flushing, it also includes important special tasks such as generator rotor removal, insertion and inspection, diesel generator excitation system renovation, PSR weakness anti-boron dilution modification, reactor coolant system automatic makeup and residual heat removal eddy current detection function, and nuclear island low-voltage switchgear renovation. The planned items for this outage total 6,119: including 3,764 preventive items, 171 strategic maintenance items, 789 periodic tests, 133 modification work orders, and 1,262 other types of work.

Main Piping and Surge Lines for Unit 2 of Xudabao Nuclear Power Plant Arrived at Site
On August 22, the main piping and surge lines for Unit 2 of Xudabao Nuclear Power Plant were successfully delivered to the site, laying a solid foundation for the commencement of main piping welding, a Level-1 milestone. The main piping serves as the aorta of the reactor coolant system. Together with the reactor pressure vessel, steam generators, and reactor coolant pumps, it forms a closed loop and pressure boundary. It is not only the core pipeline carrying the circulation and transfer of the reactor coolant but also a critical safety barrier for the nuclear island, making it an essential component of the nuclear island's core equipment. To ensure high-quality and on-time delivery of the equipment, Liaoning Nuclear Power took the lead in coordinating with the general contractor, procurement party, and equipment manufacturers, establishing a three-tier coordination mechanism of "daily reports + weekly meetings + monthly executive meetings" to fully streamline the information chain. Through measures such as optimizing production processes, mobilizing superior production capacity, and implementing continuous operations, all tasks were completed on schedule, ensuring the equipment was shipped and delivered to the site as planned.
