(Summary description)During the two sessions this year, Premier Li Keqiang mentioned "nuclear power" three times in the government work report, and proposed that "three generations of nuclear power technology have made great progress in China". From the introduction of foreign technology, to digestion and absorption, to the birth of independent brands, and then to "going "Going out" to join the international market competition, China is moving from a nuclear power country to a nuclear power country.

In 2008, the State formally approved the "General Implementation Plan for Major Projects of Large-scale Advanced PWR Nuclear Power Plants", re-innovated based on the introduction, digestion, and absorption of the world's most advanced third-generation nuclear power technology, and the design and construction of China's independent intellectual property rights The large-scale advanced pressurized water reactor nuclear power plant demonstration project has formed an advanced nuclear power plant series with China's own brand. The major project of the large-scale advanced pressurized water reactor nuclear power plant is one of the 16 major science and technology projects identified in the "Outline of the National Medium- and Long-Term Scientific and Technological Development Plan (2006-2020)" and strives to achieve breakthroughs in the next 15 years, and is a symbol of China's construction of an innovative country. Sex engineering.

Changzhou Bayi Cable Co., Ltd., under the technical guidance of the Shanghai Nuclear Engineering Research and Design Institute and the State Nuclear Instrumentation System Engineering Co., Ltd., has developed rod-level signal cables for nuclear power stations and nuclear power stations for the third-generation nuclear power national nuclear pressurized water reactor demonstration project. There are four product series: rod-controlled stack-top control cables, 1E-class prefabricated signal cables in nuclear power plant cabinets, and 1E-class prefabricated instrument cables in nuclear power plant cabinets.

On November 24, 2018, the Jiangsu Provincial Department of Industry and Information Technology and the China Science and Technology Co., Ltd. (Beijing) Science and Technology Achievement Evaluation Center in Changzhou Bayi Co., Ltd. jointly organized rod-top signal cables for nuclear power stations and rod control for nuclear power stations. There are six product series of the top six product series: stack-top control cables, 1E prefabricated signal cables in nuclear power plant cabinets, 1E prefabricated instrument cables in nuclear power plant cabinets, environmentally friendly lightweight and highly flame-retardant control cables, highly flame-retardant and lightweight special-purpose computer and instrument cables. Scientific and technological achievements evaluation and new product appraisal meeting. "

The appraisal meeting invited the National Nuclear Power Expert Committee, the International Large Grid Insulated Cable China Research Committee, the Nuclear and Radiation Nuclear Safety Center of the Ministry of Environmental Protection, Shanghai Nuclear Engineering Research and Design Institute, Chengdu Nuclear Power Research Institute, China Nuclear Power Engineering Co., Ltd., and National Nuclear Power Engineering Co., Ltd., China Nuclear Shanghai Supply Chain Co., Ltd., China National Nuclear Research Institute Co., Ltd., China National Nuclear Instrumentation Engineering Co., Ltd., National Wire and Cable Quality Supervision and Inspection Center, Shanghai Cable-Hui Testing Technology Co., Ltd., Qingdao Han cable Co., Ltd., etc. Two experts and guests.

In the products identified this time, new materials and new processes are used for the signal cables for nuclear power stations and the control cables for nuclear power stations. The finished cables have been subjected to an equivalent acceleration test for 60 years and an equivalent acceleration test for 60 years. The experimental conditions of the annual radiation aging simulation test and the equivalent accelerated 60-year (150 ° C) thermal aging simulation test were superimposed on a series of rigorous test schemes to verify the performance. The test results met the requirements of the design institute technical specifications, and some indicators were excellent. Minimum specifications for class 1E prefabricated signal cables in nuclear power plant cabinets and class 1E prefabricated instrument cables in nuclear power plant cabinets

After careful review, inquiry and discussion, the participating experts and guests agreed that the rod-top stack signal cable for nuclear power plants (150 ° C, 60 years life), the rod-controlled stack top control cable for nuclear power plants (150 ° C, 60 years life), Four series of nuclear power products: nuclear power plant 1E prefabricated signal cable (minimum specification 0.13mm2, 90 ° C, 60 years life), nuclear power plant 1E prefabricated instrument cable (minimum specification 0.08mm2, 90 ° C, 60 years
