As a high-tech strategic industry, the nuclear industry imposes stringent requirements on safety, reliability, and adaptability to extreme environments. In this context, specialized robots, characterized by their radiation resistance, high-precision operation capabilities, and advanced intelligence, have emerged as one of the core supporting technologies for the development of the nuclear industry. Nuclear robots, a subset of specialized robots, are designed to operate in extreme conditions such as strong radiation, high temperatures, and corrosive environments. The standardization of nuclear robots is essential for ensuring operational safety, enhancing efficiency, and fostering global competitiveness in the nuclear industry. However, current standardization efforts have not kept pace with technological advancements. This paper systematically examines the current status and challenges in the standardization of nuclear robots. Leveraging the three-dimensional structural model proposed by Lal C. Verman, it proposes a forward-looking and comprehensive standard system framework that encompasses profession, product, and level dimensions. The framework integrates foundational, integration, and testing standards, addressing both whole robots and critical components while harmonizing national and international requirements. Additionally, it outlines implementation strategies for this standard system. The implementation strategies emphasize strategic coordination, dynamic updates, collaborative innovation, international engagement, and talent development. The standard system under development is designed to accelerate the standardization process of nuclear robots, foster technological advancements in this field, and support the intelligent and digital transformation of the nuclear industry.
