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.
