The Nuclear Auxiliary Process Group currently has 21 staff members. It undertakes key research and development projects such as the China Initiative Accelerator-Driven System (CiADS), the Accelerator-Based Medical Isotope Pharmaceutical R&D Platform (IP-SAFE), the Accelerator-Driven Advanced Nuclear Energy System (ADANES), key technologies for spent fuel recycling and utilization, and the Cooling Storage Ring for High-Density Nuclear Matter Measurement Spectrometer (CEE).

The group focuses on the frontiers of nuclear energy and nuclear technology, concentrating on core technological advancements in hot cells, high-power experimental terminals, nuclear facility auxiliary systems, and digital applications. It aims to establish an engineering design capability system that addresses nuclear physics challenges, explores intelligent operation and maintenance technologies in high-radiation environments, and supports the development of auxiliary processes for nuclear facilities, along with the industrialization of nuclear technology applications.

Based on the engineering requirements, the group is progressively advancing modularization in assembly design, manufacturing, and installation processes for accelerators, spallation targets, shielding, and auxiliary systems. This shift from single-disciplinary design to collaborative system design is supported by the use of a 3D collaborative design platform, enabling equipment layout, site planning, and engineering implementation and management within a unified design environment.

In response to nuclear energy development needs, the group conducts remote handling and maintenance design and functional validation. Its core research areas include heavy-duty remote handling systems, radiation-resistant vision and sensing systems, digital twin simulation and virtual reality, and maintainability assessment. Additionally, the group is responsible for the maintenance and repair of process equipment for the CiADS project, as well as tasks such as technical upgrades for radiation-related auxiliary processes, aging management, in-service inspection, and target and fuel replacement operations.
