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 paper discusses the physical and mathematical foundations and possible applications of the intensity correlation method for spatial three-dimensional (3-D) positional detection (finding the 3-D spatial position) of distant γ-ray or neutrino sources in real time or after a set of registered events. This method is based on the correlation of intensities of event sequences measured by several spaced-apart distant detectors. A specific consideration is made of the possibility of using a correlation intensities method for the analysis of the processes within a nuclear reactor, for the search of the hypothetical intra-terrestrial georeactor (planetocentric nuclear fission reactors), for the optimization of the method of single-photon-emission-computed tomography in medicine, and for other applications. The conditions of successful applications of the intensity correlation method for these systems are determined. The main problem with this method is connected to a relatively low count rate of registered neutrino events.
