Fuqing Nuclear Power Construction site construction of various units of continuous construction, to overcome the adverse effects of holidays, suspension, design changes and other unfavorable factors, and timely realization of the “roof hanging special plan” in the relevant goals.

On the same day, on April 19, the first siding of the steel lining of Fuqing Nuclear Power Unit No. 6 was successfully hoisted, marking the start of the assembly of the steel lining on the top of the unit.

The steel lining of the dome is an important part of the nuclear island reactor containment. It is located at the top of the reactor building of the nuclear island. The steel lining of the dome is a hemispherical structure with a diameter of 46.8 meters. There are 422 anchors on the dome, which make assembly difficult and quality requirements. high. The assembly of Unit No. 6 steel dome lining started smoothly. It not only met the requirements of the No. 3 unit three-level integration plan, but also successfully completed the assessment of the company’s company and opened a good head for the hoisting of the No. 6 unit.

In this year’s “Government Work Report,” it is proposed that the blue skies be firmly defended. Taking heating as an example, Qian Tianlin, member of the National Committee of the Chinese People’s Political Consultative Conference and general manager of China Nuclear Power Co., Ltd., saw the possibility of “multi-functional modular small reactors and swimming pool-type low-temperature heating reactors that emit light and heat in the blue sky”. The cogeneration of heat and power can be realized, and the heating can be realized at the same time as the heating.The pool-type low-temperature heating reactor is specially used for the winter heating in the north.The people are very concerned about the elimination of haze. Many experts have passed the academician experts organized by the China Association for Science and Technology. Demonstrating that the central government has proposed an option to use nuclear energy as a clean energy source for heating, that is, mature technology itself.”

However, in winter that can really use nuclear heating, we have to wait.

Qian Tianlin mentioned that “at the moment, we should say from the technology to the stage of turning the product into a product. After the demonstration and verification, it will be changed from the product to the commodity stage. Nuclear is a very sensitive topic and it is transferred from technology to At the stage of the product, we have to do a lot of argumentation work, and let the people feel more at ease. At present, we are developing the site and we are also doing the relevant design work for the technology. We have also carried out relevant demonstration work.”

Sun Qin, deputy to the National People’s Congress and member of the National People’s Congress, said, “There are actually many other aspects of nuclear technology applied in nuclear medicine, industry, and agriculture. Now our nuclear energy technology research and development, including the industrialization of nuclear energy technology, is still in the process. Nuclear energy workers must have a sense of urgency and responsibility, and provide us with better technical services and industrial guidance from the supply side for social and economic development.”

In order to ensure the smooth running of the circulating water pump load test vehicle, the Tianwan Project Department held a number of meetings to sort out the relevant constraints and implement them one by one. After close cooperation and concerted efforts by all parties, the circulating pump has been successfully completed with the on-load test run. (Li Chuanming)

On the same day, on February 20th, Tianwan Nuclear Power Unit 3 conventional island water ring vacuum pump test work was successfully completed. At this point, the conventional island No. 3 unit five vacuum pumps were all completed single debugging, all parameters were qualified, and the steam turbine condenser vacuum The establishment laid a solid foundation.

In order to ensure the smooth running of the vacuum pump test, the Tianwan Project Department organized various units and departments in advance to sort out the relevant constraints and implement them one by one. Each pump was carefully sorted out before the test run. After all parties cooperated and cooperated, Tianwan Nuclear Power’s No. 3 unit conventional island vacuum pump was successfully completed.

The “Hualong I” steam generator is the advanced concept of the nuclear power generation technology that has been widely adopted by CNNC in the second generation of improved nuclear power station steam generator design. It has made a number of major technological improvements, and its safety indicators and technical performance have been achieved. The advanced level of the international three-generation nuclear power technology has complete independent intellectual property rights.

Dongfang Electric (Guangzhou) Heavy Machinery Co., Ltd. undertook the manufacturing task of the “Hualong-1” steam generator. In order to overcome technical difficulties, the “Hualong-1” steam generator research group was set up, and the deep hole processing of the tube sheet was conquered. , Tube supporting plate Plum hole broaching process, tube bundles and support plates and other internal assembly processes, closing the gap heat treatment anti-DING and other technical difficulties, the final completion of the steam generator.

The success of the Hualong No. 1 steam generator water pressure test will speed up the construction of the CNNC demonstration project and signify that China’s nuclear power is steadily moving toward the world. At 11:50 pm on November 25, 2016, the first hydraulic pressure test of the ACP1000 steam generator made in China was successfully completed by Dongfang Electric (Guangzhou) Heavy Machinery Co., Ltd. This node marks the “China Dragon Nuclear Power Group Co., Ltd.” The end of the manufacturing process of the first nuclear island master equipment. The steam generator is the key equipment for energy transfer in the primary and secondary circuits of nuclear islands and is the second barrier for nuclear power plant nuclear safety. Under the witness of the Nuclear Safety Bureau North China Railway Station, Fuqing Owner, nuclear power plant, engineering company leaders and supervision and manufacturing representatives, the test has undergone the work pressure, design pressure and test pressure test as stipulated in the technical documents in order to meet the technical specifications. The first and second side hydrostatic pressure tests were passed once.
