On December 26, 2023, Zhou Jianbo, Deputy Director of the South China Nuclear and Radiation Safety Supervision Station of the Ministry of Ecology and Environment and head of the Taipingling Supervision Group, and Qiao Piye, member of the Party Committee and Deputy General Manager of Huizhou Nuclear Power Plant, signed and confirmed that the welding control point of the main pipeline of Unit 2 of Guangdong Taipingling Nuclear Power Plant was approved to be released.
Due to the important impact of the welding quality of the main pipeline on nuclear safety, the National Nuclear Safety Administration has set the main pipeline welding as the only control point after the first tank of concrete pouring and before charging, and the follow-up work can only be carried out after the formal consent of the regulatory department.
In order to promote the release of the control point, Huizhou Nuclear Power and related participating units were guided by the spirit of the 20th National Congress of the Communist Party of China, turned the advantages of party building into a force to overcome difficulties, planned in advance, jointly established the corresponding self-inspection organization and inspection organization, held a self-inspection kick-off meeting and an inspection preparation meeting, and made various preparations before the inspection.
From December 11 to 15, 2023, the South China Supervision Station organized and carried out an inspection of the welding control point of the main pipeline of Unit 2. Huizhou Nuclear Power Co., Ltd., all participating units and related professions took the initiative to cooperate with each other, efficiently completed the inspection work, and the inspection achieved the expected purpose.
In response to the management requirements and inspection problems raised by the inspection, all majors responded positively, formulated the corresponding rectification plan and completed the prerequisites for the release of the control point at the first time, and submitted the rectification report to the South China Supervision Station in a timely manner, creating favorable conditions for the release of the main pipeline welding control point.
On December 26, 2023, the South China Supervision Station listened to the report of Huizhou Nuclear Power on the preparation of the welding work of the main pipeline of Unit 2 of the Taipingling Project and the rectification of inspection problems. After listening to the report, Zhou Jianbo put forward three specific opinions: first, the overall main pipeline welding work of Unit 2 is fully prepared, the conditions are good, and the conditions for carrying out the welding work have been metSecond, the follow-up of the project should continue to optimize the work process, actively learn from good practices and excellent experience, and continuously improve the construction standards of the projectThird, we should continue to strengthen communication and contact with the supervisor, and constantly promote the improvement of the project.
Zhang Liming, assistant general manager of Huizhou Nuclear Power, expressed his gratitude for the guidance and support of the South China Supervision Station, and said that the project will continue to benchmark and learn from the effective experience of other power plants in the future, and continue to improve and upgradeAt the same time, it is necessary to pass on the idea that strict management is love and the concept of nuclear safety culture to every employee.
The South China Supervision Station inspected the relevant work preparations on the spot in the welding control area of the main pipeline of Unit 2, verified the preparation of the main pipeline group of Unit 1 and the welding consumables of the welding machine, and confirmed that Unit 2 of the Taipingling Project has met the conditions for main pipeline welding and can implement the main pipeline welding activities.
The journey is strong, and the heavy task is to work hard. Witnessed by all relevant parties, Huizhou Nuclear Power and South China Supervision Station jointly signed and confirmed the release of the main pipeline control point. Thanks to the joint efforts of the project construction team, the control point was successfully released, which created favorable conditions for the coordinated promotion of the construction of the unit project, the implementation of important engineering nodes such as nuclear circuit flushing and cold test of Unit 2, and provided strength for promoting the high-quality construction of the "three major projects" of Taipingling Power and realizing Chinese-style modernization.
Li Haoran and Peng Gongbin of South China Supervision Station, Li Ning, Zhao Min and Mu Hao of Huizhou Nuclear Power Plant, Liu Jinyan of Supervision Company, Qiu Zhigang of Engineering Company, and Wang Fuqiang of No. 23 Company attended the event.
