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.

As numerical methods and computational capacities improve, there is a greater ability to leverage more complicated physics for engineering design analyses. The primary objectives of this new modeling tool are to (1) implement medium-fidelity physics within a framework that allows for the combination of simplified modeling accuracy with detailed physics tools and (2) enable postprocessing analytics that reduce time to design. These types of tools are considered a requirement to ensure modern designs are not constrained by the tools themselves. One of the novel features of this software is flow searching, which simultaneously resolves the mesh and determines flow parameters that will allow for achieving either pressure equalization or isothermal exit conditions among user-defined groupings of channels. A space nuclear propulsion example using MixcoatlTM has been included to illustrate the use of this feature.
