Development Analysis of Nuclear Thermocouple Technology at Home and Abroad Based on Patent Data and Research on Development Countermeasures in China
Nuclear thermocouples are commonly used in temperature measuring instruments in the field of nuclear power,and play a vital role in the development of nuclear power.In order to respond to the national nuclear power development plan and promote the development of nuclear thermocouple related industrial technologies,this paper comprehensively analyzes the development of nuclear thermocouple technology from the aspects of market layout,technical fields and application of related patents by means of patent navigation and literature review.The results show that:(1)The research and development trend of nuclear thermocouples at home and abroad shows an"M"type cyclical change,and China gradually becomes the main research country and patent distribution area;(2)Nuclear power thermocouple patents are mainly distributed in the two technical fields of thermocouple preparation and application,and related patent technologies are mainly applied research in core,fuel elements,protective shells and other key systems(including first and second circuits),and the scope of research shows a trend of continuous expansion and patent technology refinement;(3)Domestic nuclear power thermocouple patent technology tends to be applied research,and most patents are concentrated in the hands of a few innovation entities.Finally,this paper puts forward some suggestions from the patent market layout,technical cooperation and research hotspots of nuclear power thermocouple.
