Pressurizer of Zhangzhou Nuclear Power Unit 3 Hoisted into Place

At 19:03 on September 20, the pressurizer of Zhangzhou Nuclear Power Unit 3 was hoisted into place. During this pressurizer hoisting operation, the pressurizer was horizontally lifted to the +16.5m platform by a gantry crane, transported by a heavy-duty vehicle into the reactor building, then turned and erected by the polar crane, and finally hoisted into place. The pressurizer is one of the core main equipment items of the nuclear island reactor coolant system, and its main functions include primary loop pressure control and overpressure protection. When the temperature and pressure inside the reactor fluctuate, the pressurizer can maintain the temperature and pressure within the reactor in a safe range by adjusting the flow rate and temperature of the coolant water, ensuring the safe and stable operation of the reactor. At the same time, the pressurizer is...

CGN's 33 in-operation nuclear power units achieve RMB-denominated pricing and settlement for operational period insurance

On September 10, the "CGN In-Service Nuclear Power Plant Operational Period Insurance Project Co-Insurance Agreement" was signed in Shenzhen. The agreement achieves RMB-denominated pricing and settlement for major types of nuclear power plant operational period insurance, changing the convention of China's nuclear insurance market's over thirty years of primarily relying on foreign currency transactions. Nuclear insurance is an important type of insurance for ensuring the safe and stable operation of nuclear power units. Due to the enormous insured amount of a single policy, it typically requires joint underwriting by hundreds of insurance companies both domestically and internationally, and is regarded by the insurance industry as one of the most special and complex types of insurance. Since China's first nuclear power plant operational insurance policy——the Daya Bay Nuclear Power Plant operational insurance policy——was issued in 1993, China's nuclear power industry has long followed mature foreign models...

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.

Zhangzhou Nuclear Power Units 3 and 4 Trench Civil Engineering Completes Milestone Phase

On August 27, with the final cubic meter of concrete poured into place, the B1 and B6 sections of the GS and GB trench civil engineering works for Zhangzhou Nuclear Power Units 3 and 4, undertaken by CNNC Huachen, along with the No. 4 overflow well, successfully completed their milestone phase. This phase involved multi-disciplinary cross-operations spanning civil works, installation, electrical, and piping, characterized by complex construction conditions and significant coordination challenges. Among these, Section B1, as the project's main critical path, featured narrow working areas, difficult access for large equipment, and intensive vertical and horizontal cross-operations among multiple units. Seven days before commencement, the project department established a dedicated planning team to verify site conditions, material routes, and cross-operation scopes drawing by drawing, identifying key difficulties such as foundation pouring, equipment positioning, and material supply, and conducting multiple rounds of discussions to optimize the construction plan. The construction period coincided with the rainy season, and Section B1, situated in a low-lying area, faced a high risk of rainwater backflow. The project department implemented measures including full-coverage rain shelters over the base slab, water-retaining curbs at passage openings, and round-the-clock pumping in two shifts, securing dry working areas amid accumulated water; simultaneously, discarded waterproof membranes were collected and reused to cover rebar cages and scaffolding, preventing corrosion and slippery conditions. On-site daily meetings were held, management personnel maintained 24-hour duty, and verbal confirmation with signed handovers was practiced, ensuring issues were resolved the same day, with no plan failures, rain-related stoppages, or process disconnections throughout the period. Facing the immense scheduling pressure from multi-process cross-operations, the project department established a dynamic scheduling system. In terms of manpower loading, fixed posts and personnel quotas were implemented, with zonal responsibility and flexible reinforcement; during peak periods, core work crews were consolidated and work areas were precisely delineated. For machinery, a dynamic scheduling ledger was established, with tower cranes, excavators, and lifting equipment staggered and cross-utilized. Material coordination was also optimized through advance stocking, zoned storage, dedicated management, and emergency replenishment. During the campaign, when the transport of main materials was obstructed, the project department organized management staff and labor crews to manually carry rebar, pipes, and auxiliary materials point-to-point to the working areas, effectively safeguarding project progress. Currently, the main structure construction of the GS and GB trenches by the Zhangzhou Nuclear Power Project Department has achieved phased results, with the GB trench completing 74 sections cumulatively, an 82% completion rate, and the GS trench exceeding 1,160 meters, accounting for 72% of the total length. The company will further strengthen construction organization, optimize construction logic, and continue to advance the remaining sections of the Zhangzhou Nuclear Power Project Department, fully ensuring high-quality performance of the contracted projects.

Half of Turbines at Hungary's Paks Nuclear Power Plant Back in Operation

Hungarian Prime Minister Péter Magyar stated that the Paks Nuclear Power Plant has restored approximately half of its generating capacity, with full restoration expected to be completed earlier than originally planned. Four of the plant's eight turbines are currently in operation, and restoration efforts are ongoing. Magyar said on social media that operating conditions at the plant have improved as construction work near the Paks site progresses and the Danube River water level recovers. Based on the current pace, the Paks plant is expected to regain a generating capacity of 2,000 megawatts by Wednesday, which could meet about 35% of Hungary's electricity demand. Earlier, Unit 3 of the Paks plant was announced to resume power generation ahead of schedule on Saturday evening. Magyar noted that the unit's resumption of power generation is linked to on-site engineering measures and changes in the Danube water level.
