Known Inconsistencies (GeoNuclearData vs. WNA vs. IAEA PRIS)

Operational Reactors

  • There are currently 422 reactors listed as being operational in the GeoNuclearData database, the same number as in the PRIS database. Although the China Experimental Fast Reactor (CEFR) is grid-connected and occasionally producing 20 MWe net, it is omitted from the WNA's operating nuclear power reactors table (see here) because it is considered minor and experimental, but it is included in IAEA figures for operational reactors (see here).

Reactors Under Construction

  • The number of reactors listed as being under construction in the GeoNuclearData database does not match with either the number of reactors under construction from WNA's database or with the number from the PRIS database:
    • BALTIC-1 reactor (Russia) is shown as under construction in PRIS, but it was removed from the WNA's database in November 2000 (see here);
  • In addition to the list of reactors under construction from the PRIS database, the GeoNuclearData database also contains the following reactors (as in WNA's database):


  • The GeoNuclearData database usually follows the naming conventions from PRIS for reactors, but in WNA's database some nuclear reactors have completely different names. Some examples are:


  • the coordinates found in GeoNuclearData database are approximate;
  • the original source for the existing coordinates was an old Google Fusion Table dating back to March 2012 (probably sourced from WNA). Since the inception of this database some of the coordinates were manually corrected using Wikipedia/GeoHack and/or satellite imagery from Google Maps;
  • the operational Akademik Lomonosov-1 and 2 reactors (Russia) and planned Bohai Shipyard FNPP and Jiaodong Shipyard FNPP (China) reactors are floating nuclear power plants thus the coordinates from this database may not necessarily indicate their current location.

Countries data is taken from Unicode Common Locale Data Repository.
Nuclear power plants data is taken from WNA/IAEA, but some other sources are used, e.g., Wikipedia.

WNA data is also taken from the IAEA PRIS reactor database, with more recent information added if available (see here).
