"This piece is the resettlement house in Tangxing Village, all of which are two-story buildings. Now it is much easier for young people in this village to marry their daughters-in-law."
"This is a newly-built hotel in Chess Bay. You can get a discount if you mention’ Sea Core’."
"This is a middle school in the county. Our old secretary went to Zhejiang on business a few days ago, just to invite a retired old principal from Jiaxing to this middle school."
After driving nearly 200 kilometers from Haikou, the staff of Hainan Nuclear Power Co., Ltd. (hereinafter referred to as "Hainan Nuclear Power") started talking as soon as they entered Changjiang County.
Hainan Changjiang Li Autonomous County is the "base camp" of Hainan’s nuclear power, and the southernmost nuclear power project in China-Hainan Changjiang Nuclear Power Station is located here. What changes can a nuclear power plant bring to a town, a city and an island? What distinctive answers will Hainan Nuclear Power give in ensuring energy supply, innovative technology and comprehensive utilization of nuclear energy?
■■ Different responsibilities:
Capable of supplying 30% electricity for the whole island.
Hainan Daily, published on March 20th, 2007, published a report entitled "Hainan provincial government expresses thanks and apologies to the residents and enterprises that implemented power rationing". On March 17, 2007, the power shortage in Hainan Province reached 390,000 kilowatts, and Hainan Province began to use electricity at peak hours, affecting about 1 million people in the province. Two days later, the Hainan provincial government expressed its thanks and apologies to the residents and enterprises that implemented the power rationing through the news media.
"At that time, almost every large enterprise in Hainan had its own spare diesel generator." Wei Guoliang, secretary of the Party Committee of Hainan Nuclear Power Co., Ltd. told reporters that in 2007, due to power shortage, Hainan Province missed the peak more than 10 times in the whole year, totaling about 230 days. Power shortage has become an important factor restricting Hainan’s economic and social development. It was in this year that Hainan Province began planning to build nuclear power plants.
Changjiang Nuclear Power Project started in 2010, and Units 1 and 2 were connected to the grid in 2015 and 2016. "The most intuitive feeling is that Hainan is really not short of electricity, and the electricity has become stable." Wei Guoliang said that in the whole year of 2017, two 650,000-kilowatt units realized a total power generation of 7.4 billion kWh, which fundamentally solved the power shortage problem in Hainan Province. "Hainan Province has a unique geographical position. With the continuous improvement of its strategic position, energy security has become the basic guarantee for the high-quality development of Hainan Province. The completion and commissioning of Units 1 and 2 provided Hainan with a power point capable of supplying 30% of the island’s electricity. "
It is also this proportion that makes Hainan become the province with the highest proportion of nuclear power in the country.
In 2010, the construction plan of Hainan International Tourism Island was officially approved; In 2019, the state proposed to build Hainan into a demonstration area of priority development of clean energy and build Hainan clean energy island; In 2020, the "Overall Plan for the Construction of Hainan Free Trade Port" was issued, and the strategic positioning of Hainan Province as a pilot zone for comprehensively deepening reform and opening up, a national ecological civilization pilot zone, an international tourism consumption center and a major national strategic service guarantee zone became increasingly clear. "Hainan nuclear power has opened a new pattern of energy supply in Hainan, greatly increasing the proportion of clean energy. At present, Units 3 and 4 of Hainan Nuclear Power are under construction. When the follow-up projects are completed, the proportion of nuclear power in Hainan Province will be further greatly increased. With a stable nuclear power’ ballast’, Hainan’s development momentum is also more sufficient. "
■■ Different breakthroughs:
"Shuanglong" co-construction, creating a multi-pile base model
Giving people "confidence" comes from the safe and stable operation of Hainan Nuclear Power Units 1 and 2.
Put on a full set of safety protection equipment, and get a temporary pass at the accreditation center in the factory. After two rounds of security checks, the reporter followed the staff into the production area of Hainan Nuclear Power Phase I. When I came to the turbine power plant of Unit 2, the display screen on the wall attracted the attention of the reporter.
On this screen, the number of days of safe operation of Changjiang Nuclear Power Unit 2 was recorded. On March 24, this number was displayed as the 1540th day. As of March 9, Changjiang Nuclear Power Units 1 and 2 have been running safely for 1500 days. It’s not only safe operation, Wei Zhigang, general manager of Hainan Nuclear Power Co., Ltd. said that with the excellent performance of Units 1 and 2, Changjiang Nuclear Power Base has also become the only nuclear power base in China where all units have maintained the perfect score of WANO comprehensive index for three consecutive years.
"There are units 3 and 4 under construction, and the semi-dome is’ Hualong No.1′. Built here is’ Linglong No.1′, the first small pile in the world. " After leaving the steam turbine plant, the staff introduced the units under construction. "They are all stacks with independent intellectual property rights. We call them’ Shuanglong Qi Fei, Three Stacks Co-construction’, and we can’t see such a combination in other nuclear power bases."
When it comes to independent intellectual property rights, Wei Zhigang is proud: "Changjiang Nuclear Power Base is the only nuclear power base in China where all units realize independent intellectual property rights." It is understood that Units 3 and 4 currently under construction are two 1.2 million kilowatt three-generation advanced pressurized water reactor nuclear power units, which adopt the third-generation nuclear power technology of "Hualong No.1" with independent intellectual property rights of CNNC, and are scheduled to be put into operation in 2026.
"Linglong No.1" is the world’s first onshore commercial small reactor, which adopts ACP100 nuclear power unit with independent intellectual property rights of China National Nuclear Corporation, with an installed capacity of 125,000 kilowatts, and its demonstration significance is even more extraordinary.
"Linglong No.1 is aimed at small and medium-sized power grids or special application scenarios such as island reef power supply and seawater desalination. It is also for this reason that Changjiang has become the most suitable place for small pile demonstration. " Wei zhigang told reporters that compared with large piles, small piles have inherent advantages in safety, economy, flexibility and adaptability of special sites. "The first in the world, the most important thing is to successfully do the project first, and then optimize and upgrade on the basis of demonstration, and achieve the ultimate versatility of nuclear energy through small reactors."
During the interview, the employees of Hainan Nuclear Power Co., Ltd. all showed the reporters the uniqueness of Hainan Nuclear Power. A grassroots employee who has worked in Hainan Nuclear Power for more than ten years talked to reporters about the past: "Secretary Lu Tiezhong of China Nuclear Power has always told us that although the nuclear power in Hainan is small in size and the environment is difficult, the nuclear power people in Hainan just want to find a way out of places that others can’t think of and do something different." This kind of "difference" has made Hainan nuclear power base’s position in Hainan, achieved good operating performance, and brought different development paths.
■■ Different "one subject and multiple":
Mutual trust between local enterprises and deep cooperation for development.
According to the reporter’s understanding, according to the relevant plan, the preliminary work of Lin Hao Nuclear Power Unit, which is currently promoted by Hainan Nuclear Power, is also in full swing.
"Guess, how long did it take to collect capital for Lin Hao nuclear power project?" Chen Bo, director of the preliminary work department of Hainan nuclear power, was full of joy. "It will be done in one day." Chen Bo’s "capital collection" refers to the data collection process in the early stage of nuclear power unit construction. According to Hou Biqiang, deputy director of Hainan Nuclear Power Pre-work Department, the pre-work "capital collection" of Lin Hao nuclear power project involves the population and distribution around the site, road construction and vehicle operation. "This information involves more than a dozen departments in the county. It usually takes more than a month to complete, and now it is available in one day."
"It seems to be a day of’ receiving capital’, but it is actually the result of more than ten years of accumulation." Wei Guoliang said with emotion, "Since we settled in Changjiang, our position is to promote local development. Changjiang County has a weak economic foundation, the iron ore resources on which it has depended for many years are being exhausted, and the traditional cement production also has bottlenecks in recent years. Hainan nuclear power is coming, and it is necessary to give Changjiang a different development. "
"Hainan nuclear power brings not only a power station, but also a group of talents with scientific and technological innovation, an opportunity and possibility for transformation and development." Chen Rumao, secretary of the county party committee of Changjiang Li Autonomous County, Hainan Province, commented on the significance of Hainan nuclear power to Changjiang.
Wei Guoliang told reporters that relying on Hainan nuclear power, Changjiang County, with a resident population of more than 200,000, has become a major scientific and technological innovation in Hainan Province. "Nuclear power is a high-tech and multidisciplinary industrial category. Using the resources of Hainan nuclear power, we have established an academician workstation in Changjiang to bring talents and projects from top universities and research institutes in China to Changjiang." In addition, Changjiang, a coastal town, has been branded as Hainan nuclear power in the fields of infrastructure construction, improvement of employment level, medical care and education. "For more than ten years, we can really feel that we have been integrated with local development." Wei Guoliang said.
Chen Rumao pointed out that at present, Changjiang County is working with Hainan Nuclear Power to build Hainan (Changjiang) clean energy high-tech industrial park. The industrial park will actively cultivate clean energy high-tech industrial clusters with nuclear power production and related industries as the core, and gradually develop and expand high-end equipment manufacturing industries, new materials industries, information technology industries and other strategic emerging industries with electric energy storage, smart grid, environmental technology and marine ecological technology as the application direction.
"Changjiang has the economic advantage of being close to the port, and the positioning of the free trade port as" three districts and one center "has also given great impetus to the local development. However, because the industrial system construction is in its infancy and the industrial support is weak, it is necessary to combine the local resource endowment and industrial characteristics to select projects with high-tech and environmental protection green attributes, high maturity and rapid formation of industrial scale for cultivation. " Focusing on nuclear power, focusing on one subject and diversifying, deeply integrating into local areas, and promoting common development, this is the way for Hainan nuclear power to take. "With nuclear power plants, there is a stable and clean power guarantee. We also have steam, water and our own wharf, which are indispensable resources for the development of the industrial park. The associated industrial chain of nuclear power is huge, which is the source of industrial park development. " Wei Guoliang said that with local support, enriching and expanding the industrial structure of nuclear power can provide a broader space and stage for the construction of Hainan’s nuclear power talent team, and also provide an industrial fulcrum for the construction of Hainan’s free trade port.
According to the reporter’s understanding, the production project of lithium carbonate energy storage materials, the first project of Hainan (Changjiang) clean energy high-tech industrial park, has successfully landed. Wei Guoliang said that if the lithium carbonate project can be successfully expanded, it will drive a series of downstream industries such as battery manufacturing and clean energy vehicles to form a huge industrial cluster. "Nuclear power is not isolated, and it is naturally driven. The development of nuclear power in Hainan should not only consider the landing of nuclear power projects, but also focus on the industrial radiation brought by nuclear power. The essence of high quality and sustainable development is here."
