Check out this ad-free map of nuclear power plants worldwide and get an idea of how many there are already.

The following arithmetic made me create this app:
Scientists keep claiming that a worst-case scenario will happen only every 10,000 years. Sounds acceptable? It is an estimate for one nuclear power plant - but there are about 400 worldwide. Fukushima could have been anticipated by doing this calculation: 1986 + (10.000 / 400) = 2011. Who can say now it has been unpredictable?

Accidents that were classified on the INES scale appear as colored circles. White = no events; up to dark red = catastrophy.

Each location provides information about
★ start of operation, year of planned shutdown
★ gross output
★ in-depth information on mobile wikipedia page
★ news (wikipedia page history)
★ overview of recent wikipedia changes
★ worst recorded event (INES scale)
★ type of reactor
★ circle with configurable radius can be drawn around each plant

Thanks to Chris, CCM and especially my brother Ralf for helping me compiling the data.
