Towards a contribution to the early V&V and evaluation of architectural solutions for Nuclear Infrastructures project delivery

This article outlines the need to implement a global method to secure the project delivery of Nuclear Infrastructures. This method articulates and put in light various concepts issued from Value Analysis, System Architecting and System Engineering. Particularly, it has to be based on appropriate modelling hypotheses promoted in Model Based System Engineering (MBSE) context. This article focuses particularly on collaborative issues of helping engineers to remain aware about and able to exchange without ambiguities, ideas, principles, data, information and knowledge that are gathered by other actors in charge of, respectively, System Architecting and System Engineering phases. The method is presented through a first set of common concepts and relations between concepts, disambiguated and formalised that will be used in a concrete Nuclear infrastructure development project.
