HISTORY OF THE IAEA ARIS DATABSE
Modernization & Utilization
❑ Funding secured in 2019 (RB-WCR Team)
❑ Technical Specification developed by C.
Batra, M. Krause, T. Jevremovic
❑ Call for proposals released in Q2, 2020
❑ Selected designer started the development
of a new ARIS platform from Q4 2020
• Regular virtual meetings
• Progressing as planned
• Completion by mid of 2021
Modernization & Utilization
General Scope of Information
IAEA Advanced Reactors Information System (ARIS)
Member States interested in having ready access to the most up-to-date information about all available NPP designs, and important development trends.
ARIS is web-accessible database that provides balanced, comprehensive and up-to-date information about advanced NPP designs and concepts: reactors of all sizes and all types from evolutionary NPPs for near term deployment, to innovative concepts still under development.
Goal – provide up-to-date information on technical features and design
parameters of Advanced NPPs
IAEA Definition of advanced NPPs [TECDOC-936 → new NES in 2021]
Advanced nuclear plant designs - designs of current interest for which improvements over
their predecessors or existing designs are expected
Evolutionary designs - advanced designs that achieve improvements over existing
designs through small to moderate modifications, with a strong emphasis on
maintaining design proveness to minimize technological risks.
Innovative designs - advanced designs which incorporate radical conceptual changes
in design approaches or configuration in comparison with existing practice. Substantial
research and development efforts, feasibility tests, and a prototype or demonstration
plant are probably required prior to the commercial deployment
Scope of Information on Advanced Designs
ARIS can sort according to:
• Reactor Type (PWR, BWR, GCR, ....)
• Coolant
• Moderator
• Spectrum (thermal, fast)
• Thermal capacity (MWt)
• Electrical capacity (MWe)
• Design Status (e.g. conceptual, basic design, detailed
design, site specific,...., under construction, etc -- IAEA
definitions are in ARIS)
• Non-electrical applications
• Design Organization
ARIS ReportsCharacteristics of Advanced Reactors
Example of a graph report
available from ARIS, which
illustrates operating inlet and
outlet temperatures of different
types of nuclear power reactors
Other available ARIS graphs and
data reports are on:
• thermal capacity
• power density
• plant efficiency
• discharge burnups

THERPRO DATABASE TRANSFER & MODERNIZATION
❑ Transfer started in 2020
❑ Analyses of the database and compatibility with IAEA
systems and rules by T. Jevremovic and J. Kinker completed
in early 2021
❑ Internal approvals completed in March 2021
❑ POC to be developed internally using product-based
approach
❑ Funding secured in March 2021 (RB-WCR Team)
❑ Technical Specification developed by T. Jevremovic and J.
Kinker
❑ POC by Jun 2021
❑ CM in July 2021
