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.

This technical note describes the influence of the transients and corrective additives on the distribution of loosely bonded forms of solid-phase corrosion products between the equipment surfaces and the primary coolant of a naval reactor plant. It is shown that the concentration of loosely bonded corrosion products increases by tenfold during the transient, and the feeding of corrective additives allows a several-fold reduction in the rate of their resedimentation on the internal surfaces of equipment, and as a consequence, improvement of corrosion product removal efficiency by cleanup filters. The proposed solutions allow removal of up to 70% of loosely bonded corrosion products from the coolant using standard filters.
