Liu Jing stated that against the backdrop of accelerating transformation of the global energy structure, the strategic position of nuclear energy in national energy security has become increasingly prominent, and thermal hydraulics is an important foundational support for the development of advanced nuclear power technology. He put forward four requirements for the high-quality development of the thermal-hydraulics field: First, promote deep integration of scientific research and engineering application, balancing basic scientific research with the resolution of engineering challenges; second, master the characteristics of new heat transfer working fluids, take major engineering projects as traction, deepen thermal-hydraulics research, and support the development of advanced reactors; third, promote coordinated layout of scientific research tackling and platform construction, rely on various facilities and platforms to carry out organized research, and unleash platform innovation efficiency; fourth, promote integrated development of education, science and technology, and talent, build a university-enterprise joint talent cultivation mechanism, and work together to cultivate talent and achieve breakthroughs in key technologies, injecting strong momentum into China's nuclear industry's achievement of high-level scientific and technological self-reliance and self-strengthening.

Xin Feng stated that CNNC has always adhered to the mission of "empowering through science and technology and benefiting through industry," coordinated development and safety, focused on national strategic strength and the building of an energy powerhouse, and made every effort to enhance nuclear science and technology innovation capability. In recent years, the group has achieved a series of results in the thermal-hydraulics field and made important progress in key thermal-hydraulics technologies for multiple advanced nuclear energy systems. The group will continue to optimize the scientific research system, play the role of a source of original technology, and work with all parties to explore new principles, new technologies, and new methods in the thermal-hydraulics field, contributing wisdom and strength to support the high-quality development of the nuclear energy industry.

Liu Jianqiao stated that the Chinese Nuclear Society has always regarded promoting academic exchange and driving scientific and technological innovation as important responsibilities, and this forum is an important measure for the society to promote the development of the thermal-hydraulics discipline and consolidate industry wisdom. He hoped that participating experts would conduct in-depth discussions and exchanges around topics such as theoretical innovation and technological breakthroughs in advanced thermal hydraulics, and work together to push China's advanced thermal-hydraulics research to a new level. The society will continue to build high-level platforms for academic exchange and collaborative innovation, support original innovation and industry-university-research collaborative development in the thermal-hydraulics field, and make new and greater contributions to promoting high-level self-reliance and self-strengthening in China's nuclear science and technology.

Yin Jingwei stated that the university implements the spirit of General Secretary Xi Jinping's important speech and important instructions during his inspection of the university, closely aligns with the needs of building a strong nation and a strong military, promotes integrated development of education, science and technology, and talent, actively advances innovative, intelligent, and green development of nuclear reactor thermal-hydraulics technology, and provides strong support for building a nuclear industrial powerhouse. He hoped that research institutions, universities, and enterprises would take this forum as an opportunity to continuously deepen collaborative innovation across industry, academia, research, and application, jointly overcome key core technologies in the thermal-hydraulics field, cultivate and strengthen the ranks of leading talent in the nuclear industry, and contribute to building China into a nuclear industrial powerhouse.

At the release ceremony of the "2024 China Nuclear Science and Technology Development Report," Ye Qizhen, Academician of the Chinese Academy of Engineering and Chief Scientist of the report, delivered an online speech. He stated that the report was organized and compiled by the Chinese Nuclear Society, bringing together the wisdom of more than a hundred experts from dozens of domestic institutions, systematically reviewing the development process of global and China's nuclear science and technology over the past nine years, and providing important academic support for national strategic decision-making and industry development planning. He hoped that the report would enhance society's understanding of the nuclear cause, consolidate industry consensus, inspire nuclear science and technology workers to scale scientific peaks, and contribute to safeguarding national energy security and achieving high-level scientific and technological self-reliance and self-strengthening.
