Waste burial problem from small nuclear reactors is the same as from large ones

antnuke-relevant1. Small Reactors and the UK’s Long-Term Nuclear Strategy. nuClear News, March 2015 “……Waste Implications The Committee on Radioactive Waste Management (CoRWM) has looked at the waste implications of a 75GW programme [ i.e Small Modular Reactor or PRISM] which would be equivalent to a programme of over 50 new large-scale reactors.
wastesIt said that since the Government has, so far, been mainly talking about the waste inventory from only a 16GW nuclear new build programme, it should consider defining a maximum size for a deep geological facility (GDF) and make clear that we might need multiple GDFs. (15)
The Environment Agency (EA) has already set a limit on the risk that may be caused by the burial of radioactive wastes of 10-6 (i.e. one in a million). (16) Figures from the NDA Disposability Assessment Report for waste arising from new EPR reactors (17) suggest that a programme equivalent to 50 large reactors would require around four GDFs.1
The US Department of Energy (DOE) has built up a momentum for SMRs by throwing hundreds of millions of dollars in cost-shared funding to jump-start the industry…..

So what are prospects for small reactors, both in the UK and globally? Former CoRWM Chair, Professor Gordon Mackerron says no SMR (properly defined) has yet been commercialised anywhere in the world, and work on them has been waning because the developers cannot find a market. This is unsurprising as their cost per unit of output is higher than the already expensive conventional, larger reactors, unless hundreds can be sold to give manufacturing economies……http://www.no2nuclearpower.org.uk/nuclearnews/NuClearNewsNo72.pdf
