Under the leadership of the board of directors of the joint stock company and Bayi, the company has developed five new products of Class 1E K3 low-voltage power cables for Hualong No. 1 nuclear power plant; Class 1E Class K1 low-voltage power cables, control cables, instrument cables and compensation cables. The last third-party qualification test (immersion test) was successfully completed on May 28, 2015, and all qualified qualification test reports were obtained on June 4, 2019. This product is provided by China Nuclear Design Institute with technical support. Since 2015, after the project was approved and approved by the National Nuclear Safety Administration for the application for extension of license, simulation parts production, factory test and third-party identification test have begun. After 4 years, finally in 2019 Major historical nodes will be completed on June 4.
The project product life reaches 60 years. The product uses two suppliers to provide key insulation and sheath materials, forming two sets of technical solutions. The third-party qualification test of the product is the key node of the project. Witnessed by the National Nuclear Safety Administration, China Nuclear Design Institute, Bayi Cable, and supplier representatives, the Shanghai testing agency has successively carried out the project's burned and electrical performance test, high temperature and high pressure (LOCA) test and immersion test of the project cable after aging. The final test results meet the requirements of the qualification test outline reviewed and approved by the National Nuclear Safety Administration.
After the five new products successfully passed the third-party appraisal test, Bayi Cable is actively organizing the preparation of the completion report of the analog parts and submitting it to the National Nuclear Safety Administration for review. The project products strive to pass the expert review organized by the National Nuclear Safety Administration by the end of June 2019, and obtain the nuclear cable design and manufacturing license issued by the National Nuclear Safety Administration before August 2019.
After the project successfully passes the qualification test, it will be an important milestone for Bayi Cable in the nuclear power field. At the same time, it fully reflects the importance of the new company and the new market of the board of directors of the joint stock company and Bayi, which will enable the company's nuclear power plant products to extend from the existing 1E class K3 instrumentation and control cables to 1E class K1 cables and 1E class K3 power cables. . At the same time, it has also broken the long-term dependence of one supplier of key insulation and sheath materials for nuclear cables, made a certain contribution to China's nuclear power safety, and laid a solid foundation for China's nuclear power to go global. In addition, Bayi Cable will continue to carry out the research and development of a full range of 1E class K1 cables for the "Guohe No. 1" and "CGN Hualong No. 1" nuclear power plants with the support of the joint stock company. Therefore, the implementation of multiple technical routes for nuclear cable research and development projects will promote the company's long-term development and become a new growth point of corporate profits and taxes, with significant economic and social benefits.
