Development of Requirements Management System of NUMO and Practical Experience With Development of the Database Contents

Decision-making and work activities in the geological disposal program need to be implemented in such a way as to fulfill various requirements such as safety, engineering feasibility, quality and socio-economic aspects. Since a stepwise approach is applied for implementing the program, the number, weighting and specific nature of the requirements will change depending on the premises and constraints in each stage of implementation. Requirements management with a long-term perspective is therefore required for consistent implementation of the program. NUMO has developed a requirements management (RM) methodology that is suitable for the long-term, stepwise disposal program in Japan, as well as a supporting requirements management system (RMS) tool. The basic concept of the RMS was already presented at the last ICEM 2009. In this presentation, we will focus on practical experience with development of the database content for the RMS.
