Abstract: Nuclear fuel elements, as the core components of nuclear reactors, play a pivotal role in energy supply, reaction control and efficiency optimization. Hot isostatic pressing (HIP), as an advanced material forming technology, has demonstrated significant application value in the fabrication of nuclear fuel elements and the treatment of radioactive waste. The development of HIP technology and the working principles of its equipment were introduced, its application advancements in the manufacturing of nuclear fuel elements, including diffusion bonding and powder metallurgy, were focusly analyzed. Additionally, the future trends and potential challenges for the application of HIP technology in the field of nuclear fuel elements were explored .
