After eight years, how did it help "Hualong No. 1" become a national business card?

General Secretary Xi Jinping mentioned in his speech at the 20th Academician Conference of the Chinese Academy of Sciences, the 15th Academician Conference of the Chinese Academy of Engineering, and the 10th National Congress of the China Association for Science and Technology: "New leaps have been made in the field of strategic high technology.
.
.
New breakthroughs
have been made in the three generations of nuclear power technology of 'Guohe No.
1' and 'Hualong No.
1'.
”

Karachi Nuclear Power Plant in Pakistan

On May 20, the first overseas reactor project of "Hualong No.
1" - Pakistan's Karachi Nuclear Power Unit 2 (K-2) completed 100 hours of continuous and stable operation acceptance, and all performance indicators reached the standard, and after 69 months of construction, the current construction, installation and commissioning work was successfully completed and officially entered commercial operation
.
This marks the successful completion of the first station of China's independent third-generation nuclear power "going global", creating the best international construction performance, and China's nuclear power has achieved from "following" to "running"

All the core equipment of such a country's heavy equipment has been domestically produced, and the localization rate has reached 88%.

As the core supplier of "Hualong No.
1", Anhui Cable Co.
, Ltd.
(hereinafter referred to as Anhui Cable Co.
, Ltd.
), a subsidiary of Far East Smart Energy Co.
, Ltd.
(hereinafter referred to as Far East Stock Code: 600869), joined hands with China Nuclear Power Engineering Co.
, Ltd.
to start the research and development
of "Hualong No.
1" nuclear-grade cable as early as 2013.

In this breakthrough battle of the independent technology of heavy weapons in major countries, the story of each component of each system constantly challenging for innovation continues to be staged
.
Taking the safety verification of nuclear power plant cables as an example, the staff must first let the cable go through a 15-day simulated high temperature environment test, then a 15-day strong alkaline solution immersion test, and finally a voltage resistance test
.
After three years of R&D and experimental work, Ancable successfully overcame the technical difficulties of the third-generation nuclear power plant cable, and developed the "Hualong No.
1" reactor type in-shell and out-shell core-grade cable, filling the domestic technology gap
.

The product has achieved three "firsts": for the first time, the special cable structure of low-smoke halogen-free flame retardant irradiation cross-linked polyolefin insulation and sheath material is adopted, which has the characteristics of compact structure, small outer diameter, light weight, high temperature resistance and radiation resistance; According to the safety requirements of the third generation of nuclear power, the harsh environmental identification conditions in the containment were determined for the first time for the "Hualong No.
1"; For the first time in China, the calculation, analysis and test of the conversion relationship between β rays and γ rays were carried out, which solved the important technical difficulties in the identification test process
.

In 2016, Ancable signed supply contracts
with the "Hualong No.
1" demonstration reactor Fu nuclear power plant project and the Karachi K project in Pakistan.
On November 27, 2020, Fuqing Nuclear Power Unit 5 was successfully connected to the grid for the first time and issued the first kWh; On January 30, 2021, CNNC announced that Fujian Fuqing Nuclear Power Unit 5 has completed the assessment of full-power continuous operation and put into commercial operation; On May 20, Pakistan's Karachi Nuclear Power Unit 2 (K-2) completed 100 hours of continuous and stable operation acceptance and officially put into commercial operation
.
"Hualong No.
1" has moved from "shipbuilding to sea" to "sailing overseas", and has become the "national business card"
of China's nuclear power to the world.

"Hualong No.
1" is one of the three generations of nuclear motor models with the highest acceptance in the world nuclear power market, which is a major landmark achievement of China's nuclear power innovation and development, and is of great significance
to China's leap from a nuclear power country to a nuclear power power.
Ancable has always adhered to the development concept of "excellence", continuously cultivated in the field of nuclear power, and made every effort to build a senior service provider of nuclear power cables to help China's nuclear power to the world
