Catch the "Carbon Neutral" Express Train, Nuclear Power Usher in New Opportunities for Development

Published: 2021-04-16 Auther: fegroup   Hits:

"Carbon neutral" is a new term for most people. What is "carbon neutral"? Carbon neutrality refers to offsetting its carbon dioxide emissions through tree planting, afforestation, energy-saving and emission reduction, and industrial adjustment to achieve "zero emissions" of carbon dioxide. To cope with climate change and reduce carbon emissions, it is necessary to build a clean, low-carbon, safe and efficient energy system. The creation of a new power system with new energy as the main body is the key.

Anhui Cable Co., Ltd (a subsidiary of Far East Wisdom Energy Co., Ltd) has many years of comprehensive capabilities in designing, developing and manufacturing nuclear power cables and has made many breakthroughs in nuclear power.

Overcome Difficulties and Break Technical Barriers to Nuclear Power

The development of nuclear power requires safety assurance as a prerequisite. As an important electrical component of nuclear power plants, nuclear-grade cables are beyond imagination. The complex environment such as high temperature, high-pressure steam, nuclear radiation, and corrosive chemical spray in the nuclear power plant shell requires the nuclear cable to go through various accurate analysis and verification. Therefore, only cables with low-smoke, halogen-free, flame-retardant, heat-resistant, radiation-resistant, and LOCA (loss of water accident) resistance can meet the requirements of various indicators of the harsh environment in the shell.

The research and development of nuclear power cables concentrate on cutting-edge technologies in more than ten fields such as nuclear physics, communications, chemicals, polymers, and radio. The research and development difficulty is the most difficult in the industry. Foreign companies have long monopolized nuclear power cable technology.

Based on technical solid R&D and manufacturing capabilities, Anlan independently developed 1E-class K1, K2, and K3 cables. Anlan owns 1E-class K1, K2 and K3 medium and low voltage control and instrumentation issued by the National Nuclear Safety Administration. Series cable design and manufacturing license.

The 1E-class K3 and 1E-class K2 series nuclear cables passed the product type appraisal organized by the China Machinery Industry Federation in 2001 and 2007, respectively. The K1 series of nuclear cables passed the achievements and product appraisal organized by the Ministry of Nuclear Science and Technology in 2015. They were assessed as at the advanced international level, filling the domestic gap. In 2016, they won the second prize in nuclear energy industry science and technology and the second prize in Anhui Province science and technology. The award, becoming the first company to pass the product appraisal.

Innovative Breakthrough, Supplying "Hualong No. 1"

Since 2013, Anlan has reached a cooperation with China Nuclear Power Engineering Co., Ltd. to carry out the research and development, testing, and verification of nuclear-grade cables for "Hualong One" for nearly three years, and successfully overcome the technical difficulties of cables for third-generation nuclear power plants, and developed the "Hualong Core-grade cables in and out of the shell for the No. 1 stack type. The nuclear cable product obtained the "National Defense Science and Technology Achievement Appraisal Certificate", which filled the domestic gap. In November 2020, it passed the European user requirements compliance assessment and obtained the EUR certification certificate, meeting the latest European nuclear power requirements.

The "Hualong No. 1" reactor type has achieved three "firsts" with inner-shell and outer-shell core-grade cables. For the first time, the special cable structure of low-smoke, halogen-free and flame-retardant radiation cross-linked polyolefin insulation and sheath material is adopted, which has a compact structure: Small outer diameter, lightweight, high-temperature resistance, and radiation resistance; according to the third-generation nuclear power safety requirements, the harsh environment identification conditions in the containment of the "Hualong No. 1" were determined for the first time; the relationship between β-ray and γ-ray conversion was carried out for the first time in China The calculation, analysis, and experiment of the company have solved important technical difficulties in the identification process.

On January 30, China National Nuclear Corporation announced that the world's first "Hualong No. 1" nuclear power unit, Fujian Fuqing Nuclear Power Unit 5, completed the full-power continuous operation assessment into commercial operation. "Hualong No. 1" is one of the three generations of nuclear motors with the highest acceptance in the current world nuclear power market and has become a national business card for my country's nuclear power to go global.

Unleash the Potential and Promote the Development of Nuclear Power

In terms of nuclear power plant construction, in addition to assisting in the construction of "Hualong One", Anlan has also accumulated Qinshan Nuclear Power, Guangxi Fangchenggang Nuclear Power Plant, Jiangsu Tianwan Nuclear Power Plant, Fujian Fuqing Nuclear Power Plant, Hainan Changjiang Nuclear Power Plant, Chashma Nuclear Power Plant in Pakistan, Karachi Nuclear Power Plant in Pakistan, etc. Project service experience of multiple nuclear power plant units.

At the same time, Anlan actively responded to the "One Belt One Road" initiative. In 2016, the "Hualong No. 1" demonstration reactor Fuqing 5/6 unit project and Pakistan Karachi K project signed a supply contract, becoming China's third-generation nuclear power to the world single. At present, the company's products have been exported to more than 20 countries and regions, including Pakistan, Iran, the Philippines, Vietnam, Sudan, and Bangladesh, which is of great significance for realizing the localization of key equipment in nuclear power plants and the globalization of nuclear power technology.

During the "14th Five-Year Plan" period and long term in the future, the position of nuclear energy in China's clean energy and the low-carbon system has become increasingly clear. Far East's breakthroughs in nuclear power will play an important role in optimizing China's energy structure, promoting green and low-carbon development, helping carbon peaks, and achieving carbon neutrality goals.
