• Your incisive editorial makes many strong points, not least highlighting the exigencies of potential security compromises and terrorism vulnerabilities of the planned new nuclear reactor at Hinkley Point. But there is a fatal flaw in the argument you set out. The editorial asserts: “Nuclear power has a trump card: it is a zero-carbon technology which delivers a continuous, uninterrupted supply.”
This is demonstrably untrue. On the latter point, you only have to consult the published operating record of reactors to see this is an unsustainable claim. All reactors have lengthy planned outages (shutdowns) for operational reasons; some have significant unplanned outages due to operational failures; and in the extreme case of post-accident safety prudence, such as in Japan, their 54 reactors were all closed for years after the 2011 Fukushima disaster – and became hugely expensive “stranded assets”.

On alleged zero-carbon status of nuclear plants, you repeat a similarly erroneous assertion made in your editorial of 1 October 2005 (Pre-empting debate), where you wrote: “The big advantage of nuclear generation is that it does not produce environmentally degrading emissions in the way that fossil fuel generation does.”
You printed my response to this assertion (There is nothing green about Blair’s nuclear dream, 20 October 2005) in which I set out the various ways the carbon footprint of nuclear power is substantial, if the whole “cradle-to-grave” nuclear fuel chain (uranium mining, milling, enrichment, fuel production, in-reactor fuel irradiation, storage and final long-term management) is properly calculated. I pointed out that the nuclear industry’s proponents, such as those gathered at last week’s World Nuclear Association jamboree in London, are fond of spreading fake news such as describing nuclear energy as “non-carbon emitting”. It is about time this dangerous falsehood was confined to the dustbin of history.
