Improvements to the WNA reactor database

(Web) Permanent link

The WNA reactor database has been upgraded to improve the display of information for multi-reactor sites. Before this update the icons for reactors on the same site overlapped unless the map was zoomed in close enough to separate them. This meant that when, for example, searching for all the reactors in one country only the details for the one reactor at each site would be shown when clicking on the icons.

The new update now shows one icon for each site at wider zoom levels. Clicking on these icons brings up a pop-up list of all reactors at that site relevant to your search. You can click on the name of any of the reactors in the list to be taken to the individual page for that reactor.

The list of reactors shown will match the search criteria used. If your search was for operating reactors in the UK then the list for Sizewell would only show Sizewell B.

When zoomed in the icons for each reactor now reflects its operating status. Clicking on each icon will show brief details for that reactor, again, clicking on the reactor's name in the pop-up will link to a page with full reactor details.

The different icons used are:


 Planned Planned
 Suspended Suspended indefinitely/Cancelled
 Under Construction Under Construction
 Construction Suspended Construction suspended
 Operating Operating
 Not operating Not operating
 Shut down Shut down


The icons are placed near to their respective reactors, rather than directly on top, in part to avoid obscuring the reactors.

More upgrades to the database are being developed and should be released over the coming months.
