Multi-Criteria Assessment of Organizational Forms for the Production Base for Construction of NPP with VVER-1200

Abstract

The paper is devoted to solving the scientific-practical problem of multi-criteria assessment of alternative organizational forms for the production base (OFPB) for the construction of nuclear power plants with VVER-1200 reactor units. A classification of Russian regions into four categories is proposed, depending on the availability and degree of development of existing production and transport infrastructure and other criteria influencing the determination of the preferred OFPB. Six alternative organizational forms are formulated, including a comprehensive production base at the NPP construction site, a large inter-district base, a self-sufficient regional base, a mobile on-site base, a minimally necessary base oriented towards external supply, as well as repair and modernization of existing capacities. Each alternative is assessed against a number of criteria: economic, territorial, reliability assurance criteria, temporal and organizational criteria. To solve the multi-criteria problem, the globally proven Analytic Hierarchy Process (AHP) method by T. Saaty is applied, including procedures for pairwise comparisons of criteria and alternatives with verification of the consistency of expert assessments. Full calculations are carried out with the determination of local and global priorities for all alternatives. The results of the study demonstrate that the determination of the preferred organizational form for the production base significantly depends on regional conditions, including the level of infrastructure development, investment strategy, and long-term plans for nuclear energy development in the region. The presented methodology can be applied to justify organizational and technological decisions at the pre-project stage of constructing new power units for NPP with VVER-1200.
