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.

No-public evacuation is an expectation for fusion power plants (FPPs) from the public and governments. In this technical note, a preliminary consequence assessment of an ITER wet bypass–like accident (the accident with the most severe consequence in ITER) of a helium-cooled deuterium-tritium tokamak FPP is performed and compared with that of ITER. Ideal gas–based methodology is proposed to evaluate the released materials in accidents, which is verified by typical accident cases in FPPs. The verification indicates that, compared with the best estimated codes, the proposed method is much simpler and easier with effectiveness. The accident assessment shows that this helium-cooled FPP design may still need public evacuation if the accident happens, which demonstrates the requirement of further investigations for FPP accidents. Some suggestions are proposed to improve the safety of FPPs based on the assessment.
