Collaborative Project Proposal“Global Architecture of INS Based onThermal and Fast Reactors with the Inclusion of a Closed Nuclear Fuel Cycle (GAINS)” On behalf of Scientific and Technical Committee of INPRO Joint StudyVladimir USANOV Coordinator of the Joint Study, IAEA
Overall Objectives • To create a framework (a common methodology, assumptions and tools)for analysis a transition to a globalINS ‘TR-FR&CNFC’, capable to meet in a sustainable manner requirements of energy supply • To provide for decision making an overview of economic, technologicaland institutional incentives for realization of the architecture of the INS identified for established scenarios of nuclear growth • To define potential of joint R&D, sharing experimental base and infrastructure, unification of reactors and fuels, and other collaborative activitiesenhancing nuclear penetration to the energy market • To determine areas and tasks for more detailed elaboration in specificINPRO CPs or on multi/bilateral basis
Specific Research Objectives • To establish jointly a state of art in visualization of global nuclear future • To select scenarios for a worldwide/regional deployment of NP • To define asymptotic vision of INS for every country or group of countries • To select technological options, to develop variants of the INS architecture and calculate a half-century/century dynamic transition from existing state to an asymptotic one • To make conclusions on: - synergy between reactors, and countries/regions; - incentives, terms and conditions for introduction FR and SMR; - incentives for building the regional nuclear fuel cycle centres; - impact of innovations in technology, unification of systems, etc. for facilitating the nuclear market penetration; - compliance of the different options of nuclear architecture with energy demand and requirements of sustainability
JS: Identifying Scenarios • Promising market for INS CNFC-FR: 500-700 GW by 2050 • Different national expectations in nuclear electricity growth: from about ‘zero’ up to ‘as much as possible’ • Different level of the technology development: from experimental reactors up to pilot commercial NPPs and associated fuel cycle
Stage 1: Step 1.1 - Scenarios Architecture of growth or phase out?
Step 1.1: Scenarios (cont.) • B2, A2 SRES scenarios have appeared to be in compliance with JS MS expectations (500-700 GWe.y by 2050 for JS MS while globally ~ 2000 GWe.y by 2050) • Planning and Economic Studies Section (PESS) of IAEA in contact with the JS has carried out a study with detailed overview of strategies of NP growth for one developing region of the world and has received a valuable outcome • Plans for extending the approach for GAINS with involvement more regions of the world (~ 10 regions) • Continuation of the activities and enhancing cooperation of the IAEA with other competent energy agencies on development plausible global scenarios of nuclear growth would be very important for studies like GAINS
Step 1.1: Scenarios (cont.) Europe S. America North America India + China + Africa Global Integration & Feedback Global Nuclear Energy Development Scenario Individual Region NE Development Scenario India +
Step 1.2: Asymptotic-state objectives • While intending to meet Acceptance Limits (AL) of sustainability, MS have diverse national aspirations and focus in NP development: - assurance of nuclear fuel supply for fast energy growth; - assurance of very high quality of environment, including drastic reduction of reactor waste requiring repository disposal; - competitive NPP operation assured by services from global market; - cutting inventory of fissile materials for enhancing PR features. • An important activity will be identifying of asymptotic objectives in national nuclear strategies for the time span 50 years and more • Merging of national long run strategies will help to understand ability of the global system to provide national asymptotic objectives without breaching requirements of sustainability, and most likely compel not only to tune national approaches to global picture but to use to full extent potential of the multinational collaboration
Step 1.3: Selection of INS components The main task of the step is to select components of the INS to be used in the study and to determine roughly target years of their introduction into the system Proven: LWR, HWR, SFR in operation; UOX, MOX fuel; pellet fabrication; PUREX reprocessing; HLW glass matrix + Developed & Evolving: advanced LWR, HWR, SFR; UOX, MOX fuel; pellet & vibropaking fabrication; advanced PUREX & dry reprocessing; advanced HLW calcine and glass matrixes + Conceptual: advanced HTGR, LFR, LBFR, GFR, modular-type reactors; MOX, nitride, thorium & metallic fuels; pellet & vibropaking fabrication; advanced aqueous partitioning (TRUEX, UREX, THOREX, etc.) & dry partitioning systems; advanced and composite HLW calcine and glass matrixes; regional FC Centers covering all spectrum of services
Step 2.1. The Choice of Transition Strategy • Designing of about 8-12 variants (options) of the INS architecture that provides smooth transition to sustainable energy supply for selected global scenarios • To examine potential of development of the INS basing on both expansion and transition opportunities: - expansion of once-through UOX option based on TR (OT-TR) without spent fuel reprocessing but with improved technical and economic characteristics of reactors and fuel; - expansionof one-recycling plutonium option with MOX fuel in TR; - OT-TR option withtransitionto multi-recycling plutonium option in FR (MR-FR) with mixed oxide and metal fuel; - OT-TR & MR-FR options with transition to U/Th and Pu/Th fuels; - OT-TR & MR-FR options with transition to MA management
Step 2.2: Development of Major Storylines To identify advantages of multinational collaboration, the scenarios for the INS deployment will be split into two storylines: • A heterogeneous world based on self-reliance and preservation of local identities. Nuclear services across regions converge very slowly • A convergent world with rapid changes toward a service collaboration, toward global solutions for economic, social, and environmental challenges. Building of the global and regional nuclear architecture, unification of reactor fleet, sharing infrastructure, arrangement of multinational/regional regional fuel cycle centres

Step 2.3: Simulation • A very important and even crucial element of the study will be an account of the dynamics of the system from the current to a future sustainable energy mix • The experience gained in the JS, testify need in further development of unified tools for a dynamic simulation of global/regional transition strategies and continuation activities on benchmarking of the tools • A package based on the computer codes DESAE, MESSAGE, WISTA which are being disseminated by the Agency, could become an instrument for a dynamic simulation
Step 2.4: Analysis • Indicators of INS sustainability to be analysed: - balance of radionuclides in the system; - material flows with focus on fissile materials and radwaste; - economic indices (investments, electricity cost, financial risks); - safety characteristics, - health and environmental impact; - amount, decay heat and radiotoxicity of radwaste; - fissile materials inventory and flows, and other indices important for assessment of proliferation resistance and physical protection; - other parameters needed for assessment of the INS sustainability in accordance with INPRO methodology (in total more than a hundred indicators).

Initiation of GAINS • It was noted at the SC meetings in presentations on the INPRO Joint Study (JS) on assessment of INS CNFC-FR that the Study could become a base for more deep cooperation • At 10 SCM delegation of RF initiated CPP RUS-1 as a successor of the JS to make a step from an assessment of INS to developing conceptual basis of a Global Architecture of INSbased on thermal and fast reactors (TR&FR) with the inclusion of CNFC (GAINS) • At the meeting of the JS in France in February 2007 its participants at the level of specialists agreed to support CPP GAINS for joint development at the Phase 2 of INPRO Project
Organization • Innovative and unique multinational organizational structure has been established for JS to develop INS CNFC-FR National Level: • Main funding of the activities (national input, ~ 2 CM /year) • Formation of national teams • Representation in STC and selection of a Chairman IAEA: • INPRO management, INPRO International Coordinating Group • IAEA Experts • Linkage and exchange of information with relevant IAEA CRP & CPP and with other international studies (GNEP, GIF) • Financing from RB • The organizational structure has demonstrated fitness for purpose that’s why INPRO Joint Initiative (JI) seems to be a good option for the GAINS implementation
