Qinshan Nuclear Power Completes Overhaul Validation of Grille Cleaning Robotic Arm

The grille cleaning robotic arm, an integrated system of UAV-based intelligent inspection and robotic arm automatic cleaning independently developed by the Mechanical Team of the Fourth Maintenance Division at Qinshan Nuclear Power, recently completed on-site validation during the Unit 2 312 overhaul at Qinshan Phase II. Designed for seawater system intake grille cleaning scenarios, this equipment transforms the original manual operation requiring entry into deep wells into an unmanned operation conducted under ground-based remote monitoring. The intake grille serves as a critical barrier for the cooling water system of a nuclear power plant, and its unobstructed condition is directly related to the stable operation of the unit. In traditional cleaning methods, workers were required to enter narrow shafts more than twenty meters underground to perform inspection and cleaning in confined spaces, which involved high labor intensity, low efficiency, and safety risks such as falls from height...

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.
