Integrated Nuclear Fuel Cycle Information System (iNFCIS) is a set of databases related to the nuclear fuel cycle
Nuclear fuel cycle
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in...

The International Atomic Energy Agency is an international organization that seeks to promote the peaceful use of nuclear energy, and to inhibit its use for any military purpose, including nuclear weapons. The IAEA was established as an autonomous organization on 29 July 1957...

 (IAEA). The main objective of iNFCIS is to provide information on all aspects of nuclear fuel cycle to various researchers, analysts, energy planners, academicians, students and the general public. Presently iNFCIS includes several modules. iNFCIS requires free registration for on-line access.


Nuclear fuel cycle consist of a number of steps which are critical in supporting a nuclear power programme. This included fuel
Nuclear fuel
Nuclear fuel is a material that can be 'consumed' by fission or fusion to derive nuclear energy. Nuclear fuels are the most dense sources of energy available...

 supply related activities in the front end and used or spent fuel related activities in the back-end. Reliable and accurate statistical data on world wide nuclear fuel cycle activities is desired by the nuclear community for national policy making, international co-operation and studies pertaining to sustainable global energy futures.
The IAEA provides up-to-date fuel cycle information to Member States, organizations and stakeholders, so as to understand, plan and develop nuclear fuel cycle programmes and activities. iNFCIS, a web based system comprising several nuclear fuel cycle related databases, is one source of such information.

Data sources

IAEA over years has accumulated a large volume of data on nuclear fuel cycle activities through its regular technical meetings and publications, wherein contributions from Member States and leading international experts has been assimilated. IAEA had initiated electronic preservation of this data more than 20 years back, and since the last 10 years it has been made freely available through the public Internet.
The data is regularly updated through direct inputs from the Member States, by consultants engaged by the IAEA or from open sources. All data is reviewed by consultants continuously to maintain high quality.


iNFCIS presently includes the follow databases and a simulation tool:
  • The Nuclear fuel cycle information system (NFCIS) is a scenario based computer tool for the estimation of nuclear fuel cycle material and service requirements developed by the IAEA. NFCSS is developed based on a model designed to estimate long-term nuclear fuel cycle requirements and actinide arisings.
  • The World distribution of uranium deposits database (UDEPO) is an on-line database of uranium deposits around the world maintained by the IAEA.
  • The Post irradiation examination facilities database (PIEDB) is a catalogue of hot laboratories maintained by the IAEA.
  • The Minor actinide property database (MADB) is a bibliographic database of physico-chemical properties of selected minor actinide compounds and alloys.
  • The Nuclear fuel cycle simulation system (NFCSS) is a scenario based tool to estimate material flow in the nuclear fuel cycle.


The following are the print publications based on iNFCIS:
  • Nuclear Fuel Cycle Information System:A Directory of Nuclear Fuel Cycle Facilities 2009 Edition
  • The Nuclear Fuel Cycle Information System, 1996 Edition
  • The Nuclear Fuel Cycle Information System
  • World Distribution of Uranium Deposits (UDEPO), with Uranium Deposit Classification
