First Backup Emergency Diesel Generator of Hualong One Officially Available at Sanao Nuclear Power Unit 2

On October 2, the first backup emergency diesel generator (9LHW) of Hualong One completed the replacement grid connection test at Sanao Nuclear Power Unit 2 and was officially put into service. The equipment can replace any one of the original 12 emergency diesel generators (EDGs) in Phase I and Phase II projects, significantly improving the redundancy, reliability, and maintenance flexibility of the plant's emergency power supply. Sanao Nuclear Power Phase I and Phase II each have 3 emergency busbars, with one EDG configured for each busbar. However, due to the absence of cross-power supply for loads, the preventive maintenance windows of the original units were concentrated, affecting the overhaul schedule. Since 2021, Cangnan Nuclear Power has promoted the project of adding backup diesel generators, improving from the design source, building a new backup emergency diesel generator building (BDD), and constructing corridors and cables connected to each unit...

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.

Qinshan Nuclear Power Membrane Deoxygenation Retrofit Project Put into Operation

Recently, the membrane deoxygenation retrofit project at Qinshan Nuclear Power completed commissioning and was put into operation. The project applies membrane deoxygenation technology to the auxiliary feedwater system (ASG) and reactor boron and water makeup system (REA) of Units 1 and 2 at Qinshan Nuclear Power Plant Phase II, optimizing and upgrading the original deoxygenation process. Units 1 and 2 of Qinshan Phase II originally adopted thermal deoxygenation. During long-term operation, this method presented issues such as insufficient redundancy in single-train equipment operation, high temperature and humidity on site, and potential exceedance of auxiliary feedwater tank temperature limits during summer peak temperature periods. To enhance system operational reliability, Qinshan Nuclear Power initiated relevant technical retrofits, introducing membrane separation packaged units to form a parallel standby configuration with the original thermal deoxygenation system, allowing flexible switching...

Huzhou, Zhejiang Launches Phase I "Drug-Device Combination" Clinical Trial for the Province's First BNCT System

Recently, the Boron Neutron Tumor Treatment Center at Huzhou Hospital Affiliated to Zhejiang University School of Medicine has drawn attention with the introduction of the province's first Boron Neutron Capture Therapy (BNCT) system. Previously, the system had already initiated a Phase I BNCT drug-device combination clinical trial. According to the system developer, Huapeng Neutron Technology (Hangzhou) Co., Ltd., BNCT is a radiotherapy technique combining drugs and devices, with its core lying in the coordinated use of boron-containing drugs and neutron irradiation. After entering the human body, the boron-containing drug can be absorbed by tumor cells; subsequent neutron beam irradiation triggers a localized reaction to achieve targeted radiotherapy against tumor cells. Unlike conventional radiotherapy, which typically employs fractionated irradiation over a longer treatment course, BNCT emphasizes selective targeting of tumor cells, aiming to reduce damage to surrounding healthy tissues and lower radiotherapy-related side effects such as hair loss and immunosuppression.

Construction of the conventional island raft foundation slab for Unit 2 of Zhejiang Jinqimen Nuclear Power Plant completed

At 3:36 on August 20, the raft foundation slab pouring for the conventional island of Unit 2 at Zhejiang Jinqimen Nuclear Power Plant was successfully completed. With the final batch of concrete precisely placed into the formwork, the main structure construction of the conventional island for this unit was officially initiated. The concrete supply for this pouring operation was provided by CNNC Concrete Xiangshan Branch. The operation lasted 29 hours and 20 minutes, with a cumulative supply of over 4,000 cubic meters of concrete, achieving continuous and stable material delivery. The maximum pouring thickness at this section was 3 meters, with a height difference of 7 meters at the variable cross-section locations, and the structural design service life is 60 years. The project features large-volume, high-intensity construction characteristics, compounded by the rainy climate conditions on site, imposing stringent requirements on concrete supply continuity, delivery stability, and temperature control precision.
