Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

The China Fusion Engineering Test Reactor (CFETR) is a new superconducting magnet tokamak. The vacuum vessel (VV) is one of the core components of the CFETR device, and it will provide a high-vacuum environment for the plasma, improve radiation shielding and plasma stability, and provide support for in-vessel components. The 1/8 VV sector mock-up has been designed and manufactured in the Chinese Academy of Sciences, Institute of Plasma Physics (ASIPP) from a few years ago to verify the design and key technologies to be used in the future. The production and assembly of the 1/8 VV sector are not in the same place, so lifting lugs and a support platform were designed for lifting and supporting the 1/8 VV sector mock-up. The detailed design of the 1/8 VV sector mock-up lifting lugs and support platform are described. There are two design options for the lifting lugs—removable and nonremovable—and there are also two design options—the integral and the separated—for the supporting platform. At the same time finite element analysis and assessment of the lifting lugs and supporting platform were done. The maximum stress does not exceed the allowable stress of the material, in consequence both of the two design options are practicable, respectively. All the design and analysis results will provide technical support for the assembly of the 1/8 VV sector in the future.
