CCTV News: At 8:39 on March 23, the nuclear island steel dome of the Haiyang Nuclear Power Unit 3 of the State Power Investment Corporation was officially hoisted and put into place, marking the basic completion of the main reactor factory structure.

The steel dome module lifted this time is an important part of the shielded factory of the nuclear power unit. The whole is shaped like a meter cone, with a diameter of about 41 meters and a height of about 11 meters. The total lifting weight is close to 1,000 tons.

The steel dome lifted this time is the last module of the shielded factory of Unit 3. The next step is to install the non-active containment water tank. In order to achieve the important node of the steel dome in place, the project completed the pre-works such as shielded wall construction and monorail cranes in the shielded factory and the introduction of steel platform equipment as planned. We carried out the entire process of desktop drills, joint inspection of prerequisites before lifting, etc. to ensure that the steel dome lifting is foolproof.

The National Power Investment Corporation Haiyang Nuclear Power Unit 3 and 4 are key projects of the national "14th Five-Year Plan". At present, 23 milestone nodes have been completed as planned and are planned to be fully put into operation in 2027. By then, the annual power generation of four Haiyang nuclear power units can reach 40 billion kWh, which can meet the domestic electricity needs of half of the residents in Shandong Province. The main project of Qinzhou pumped storage power station has been fully started. On March 23, the main project of Qinzhou pumped storage power station located in the Lingshan section of the Pinglu Canal Economic Belt in Guangxi has been fully started and is expected to be completed and put into production in 2029.

At present, the total storage capacity of the eight pumped storage projects under construction in Guangxi is 164 million cubic meters, with a total scale of 10 million kilowatts. They will be completed and put into production one after another from 2025.

After the power station is completed, it can absorb up to 19.8 billion kilowatt-hours of clean energy every year through pumping and water discharging power generation, which is equivalent to the annual electricity demand of 9.16 million residents, helping Guangxi's economic and social development to achieve a comprehensive green transformation. my country's Beibu Gulf waters have made a major breakthrough

The reporter learned from Sinopec on March 23 that the Hai301 Well located in the Beibu Gulf Basin of my country has obtained high-yield oil and gas flow. During the test of two different strata systems, this well achieved a daily oil equivalent of 1,108 cubic meters and 167 cubic meters, breaking the Nissan record of oil and gas in the Beibu Gulf Sea, showing good exploration and development potential.

The sea 301 well is located in the southwest of the Beibu Gulf Basin, about 110 kilometers from Beihai City, Guangxi. Since oil and gas exploration started in 1982, it was once considered that it has little resource potential and low commercial exploration value, and has never achieved commercial breakthroughs.

Zhao Yong, executive director of the Shanghai Offshore Oil Bureau of Sinopec, introduced that using three-dimensional seismic collection technology, the oil test of the Sea 301 exploration well reached 1,108 cubic meters of oil equivalent, indicating that the sea sag is a rich and solid sag.

my country has rich marine oil and gas resources and has become an important energy growth pole in my country. At present, my country's annual output of offshore oil fields has exceeded 60 million tons. The successful implementation of Hai301 Well confirmed that the overall oil-containing geological structure in the sea area is located, showing the characteristics of high-quality reservoirs.
