A few days ago, the nuclear island identification grease jointly developed by the Shi Science Institute and China General Nuclear Power Operation Company passed the scientific and technological achievement appraisal of the China Nuclear Energy Industry Association, marking a major technological breakthrough
in the use of grease on China's nuclear island.
Nuclear island is the general name of nuclear reactors and related systems in the containment vessel of nuclear power plants, and grease used in nuclear islands is widely used in bearings of important pumps, fans, valves and other key equipment in nuclear islands, and is a key material
to ensure the safe, stable and long-term operation of nuclear power plants.
Due to the special working environment, the grease has strict requirements for high temperature resistance, radiation resistance, long life performance, etc.
, and its production technology has been monopolized by foreign brands for a long time, and once became a "forbidden zone"
for domestic lubricating grease.
The nuclear island identification grease jointly developed by the Institute of Stone Sciences has excellent anti-corrosion and anti-rust performance, oxidation resistance, extreme pressure and wear resistance, and outstanding
comprehensive performance.
The appraisal expert group unanimously agreed that the nuclear island identification grease has independent intellectual property rights, reached the international advanced level, filled the gap of domestic related products, and can be promoted and applied
in nuclear power units.
The successful research and development of nuclear island identification grease has enhanced the level of independent innovation in the field of spare parts in China's nuclear power industry, and provided strong technical support
for ensuring the safe operation of China's nuclear power plants and enhancing the core competitiveness of China's nuclear industry.
