The China Nuclear Energy Industry Association recently hosted an appraisal meeting of 12 scientific and technological achievements, including the “Analysis Technology for Atmospheric Diffusion Simulation of Inland Nuclear Power Plant Sites”, at the Shanghai Nuclear Research Institute. The appraisal expert group carefully reviewed the research report of scientific and technological achievements, carefully listened to the work report, and conducted in-depth exchanges with the research group on related issues. The expert group believes that the 12 scientific and technological achievements identified this time have a high level, outstanding innovations, and strong novelty and creativity.
The information shows that the "Probabilistic Safety Evaluation Calculation Engine" relies on major special topics to establish a probabilistic safety evaluation (PSA) model analysis technology based on binary decision diagram (BDD) and zero-compression binary decision diagram (ZBDD), forming an autonomous system. The calculation engine software of intellectual property strongly supports the quantitative calculation of PSA of CAP1400, which has important engineering application value. The results are leading domestically and reach the international advanced level of similar technology.
"Inland nuclear power plant site atmospheric diffusion simulation analysis technology" relies on major special subjects, through field tracer tests, obtained experimental data of large-scale natural ventilation cooling tower pollutant diffusion and local environmental impact, and solved the technical difficulties of atmospheric diffusion mode verification ; Carrying out research on the influence of the air inlet at the bottom of the cooling tower on the local circulation, revealing the influence of the cooling tower on the diffusion of gaseous effluent, filling the gap in the field in China; independently developing the simulation of atmospheric diffusion parameters in the near area of nuclear power plants The program makes up for the deficiencies of traditional tracer experiments, turbulence observations, and wind tunnel tests. The achievement has independent intellectual property rights, and applied for a total of 5 technical secrets (1 core technical secret); the method system formed was the first in China and reached the international advanced level.
"Several key technologies and applications to improve the nuclear power station's ability to resist tsunami and waves" relying on the key scientific and technological research projects of the Shanghai Municipal Science and Technology Commission, the nuclear power plant's resistance to sea waves and its floating objects' impact capacity, wave volume, and seismic performance were analyzed and evaluated. , The first time in China to establish a complete nuclear power plant anti-tsunami and wave capacity analysis technology system. The subject has applied for 3 national invention patents, obtained 2 software copyrights, published 6 SCI / EI source journal papers, and trained 11 backbone engineers and graduates. It is the first time for research and application in China, and it has significant innovation. The overall technology is at the domestic first and international advanced level.
