The third batch of 20 scientific and technological achievements implemented by the Shanghai Nuclear Engineering Research and Design Institute passed the centralized appraisal organized by the China Nuclear Energy Industry Association. The appraisal committee consists of China National Nuclear Corporation, China General Nuclear Power Group, Tsinghua University, National Nuclear Power Technology Corporation, Shanghai Jiaotong University, Xi'an Jiaotong University, Nuclear and Radiation Safety Center, Shanghai Electric Group, China Zhongyuan Foreign Engineering Co., Ltd., and Dongfang Electric Group. It is composed of well-known experts in the industry, and Ye Qichen, a member of the Chinese Academy of Engineering, serves as the director of the appraisal committee.

Including "CAP1400 Electromagnetic Stop Valve", "CAP1400 Non-active Core Cooling System Performance Test and Validation Study", "Study of Dynamic Characteristics of CAP1400 Internal Components in Air and Still Water," "Nuclear Power Station Earthquake Monitoring System Development", The results of the "CAP1400 main control room nuclear air ejector" and other results passed the appraisal.

The appraisal committee unanimously considered that the third batch of 20 results was generally "leading domestically and reached the international advanced level", and some of the achievements had reached the "leading international standards."

Ceramic Blade

Ceramic blades have excellent wear and corrosion resistance, and have tougher edges that stay sharp longer than traditional steel knives. Usually made of zirconia. Due to the purity of raw materials and grain refinement, various carbide, nitride, boride and oxide additives are added to improve their properties, and at the same time, the fracture toughness of zirconia ceramic inserts is improved through the synergistic effect of particles, whiskers, and phase transformations. Microcracks and several toughening mechanisms. Not only does the flexural strength increase to 0.9-1.0GPa (up to 1.3-1.5 GPa), the fracture toughness and impact resistance are greatly improved. Therefore, it is called "ceramic steel" in various advanced ceramics.
