Light Water Reactor Sustainability Program: Digital Architecture Requirements

Abstract

A major objective of the LWRS program is the development of a seamless digital environment for plant operations and support, integrating information from plant systems with plant processes for nuclear workers through an array of interconnected technologies. The digital architecture is defined as a collection of information technology (IT) capabilities needed to support these digital interconnected technologies. This collection of IT capabilities must in turn be based on a set of requirements that reflect the intended use of the interconnected technologies. These requirements, simply put, are a statement of what sorts of digital work functions will be exercised in a fully-implemented seamless digital environment and how much they will be used. This report describes an initial set of requirements for the digital architecture in terms of I&C and IT capabilities needed to support NPP work activities employing new digital technologies identified and developed in other pilot projects within the II&C Pathway. This report presents the user requirements in four areas of nuclear power plant (NPP) digital technologies:
