A Model Based System Commissioning Approach for Nuclear Facilities

Commissioning is considered as a critical phase in the delivery of Nuclear Facility (NF) it first stage authorization NF to be exploited. Most nuclear projects start overrun costs during commissioning mainly since this not addressed properly and affected by many issues from previous phases (Design, Procurement, Construction). This article proposes general methodology prepare realize activities. Using models do so improves communication removes ambiguities between stakeholders. It also formalizes clarifies organization activities prior any implementation. allows for capitalizing sharing experience projects, drawing references good practices patterns. The so-called Model Based method elaborated around concepts, languages, processes, tools, patterns inspired System Engineering (MBSE) principles practices. theoretical foundations will supported results facilities demonstrating added value.
