The triple shock of a huge earthquake, a devastating tsunami and an unfolding nuclear accident rocked Japan in March, and my condolences go out to all the many thousands affected.
Luckily, none of this could never happen here in Britain. Or could it?
Despite public disquiet over the safety of the industry since Three Mile Island and Chernobyl, nuclear power has regained political favour in recent years.
Amidst desperately slow progress in investing in renewables to fill a looming energy gap in the UK, successive governments have presented nuclear as a clean, cheap and proven solution which also offers zero carbon emissions.
Faced with public concerns after Fukushima, ministers have maintained that the UK is unlike Japan because there are no appreciable seismic risks. We do have earthquakes, but mostly they are minor.
But low seismic risk falls far short of guaranteeing safety. The more important question is whether there are risks from geological or meteorological events which could threaten the safety of our existing and future nuclear power plants. And I’m afraid the answer is a resounding yes.
