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.

In this study, a three-dimensional transient metal hydride model is applied to two different depleted uranium (DU) bed designs. One bed is designed to contain 1.86 kg DU for a hydrogen isotope storage capacity of 70 g, and it is loaded with copper foam to enhance internal heat transfer. The other bed is designed to contain 5.26 kg DU for a hydrogen isotope storage capacity of 200 g, and it uses copper fins to enhance internal heat transfer. A numerical study is conducted to analyze the dehydriding characteristics of two different DU bed designs. A parallel computing methodology is used to effectively reduce the computational turnaround time involved for full-scale DU bed geometries. The detailed simulation results show the evolution of temperature and hydrogen-to-metal atomic ratio contours at different hydrogen desorption stages and reveal the different DU dehydriding behaviors of the two DU beds. In sum, the present work elucidates the effects of key bed design parameters and helps identify optimal DU bed design strategies to effectively charge and discharge hydrogen isotopes.
