The let\u00adter sets out concerns about the control and ins\u00adtru\u00admen\u00adta\u00adtion (C&I) of Areva\u2019s European Pressurised Reactor (EPR).<\/p>\n Described by one nuclear indus\u00adtry source as the \u201ccere\u00adbral cor\u00adtex\u201d of a nuclear power sta\u00adtion, C&I governs the com\u00adpu\u00adters and sys\u00adtems that moni\u00adtor and control the station\u2019s per\u00adfor\u00admance, inclu\u00adding tem\u00adpe\u00adra\u00adture, pres\u00adsure and power out\u00adput levels.<\/p>\n The NII, which is conduc\u00adting a detai\u00adled review of two reac\u00adtor desi\u00adgns for the UK, said the EPR tech\u00adno\u00adlo\u00adgy was signi\u00adfi\u00adcant\u00adly com\u00adpro\u00admi\u00adsed because of the inter\u00adcon\u00adnec\u00adti\u00advi\u00adty of what were meant to be inde\u00adpendent sys\u00adtems desi\u00adgned to ope\u00adrate the plant and ensure its safety.<\/p>\n The Health and Safety Executive, which over\u00adsees the NII, said that the EPR desi\u00adgn could be rejec\u00adted for use in Britain if its concerns could not be satis\u00adfac\u00adto\u00adri\u00adly addres\u00adsed. \u201cIt is our regu\u00adla\u00adto\u00adry judg\u00adment that the C&I archi\u00adtec\u00adture appears over\u00adly com\u00adplex,\u201d the NII let\u00adter said. \u201cWe have serious concerns about your pro\u00adpo\u00adsal which allows lower safe\u00adty class sys\u00adtems to have write access [the abi\u00adli\u00adty to over\u00adride] to higher safe\u00adty class sys\u00adtems,\u201d it continued.<\/p>\n The let\u00adter also high\u00adligh\u00adted concerns about the absence of safe\u00adty dis\u00adplay sys\u00adtems or manual controls that would allow the reac\u00adtor to be shut down, either in the station\u2019s control room or at an emer\u00adgen\u00adcy remote shut\u00addown station.<\/p>\n The NII\u2019s war\u00adning will com\u00adpound the view that EDF, the uti\u00adli\u00adty giant that is 85 per cent owned by the French state, is unli\u00adke\u00adly to meet its tar\u00adget of buil\u00adding its first UK reac\u00adtor within eight years.<\/p>\n Areva is alrea\u00addy scram\u00adbling to pro\u00adduce revi\u00adsed plans but the desi\u00adgn assess\u00adment phase could be delayed well past its expec\u00adted com\u00adple\u00adtion in 2011.<\/p>\n EDF wants to build four reac\u00adtors in Britain at two sites, Hinkley Point in Somerset and Sizewell in Suffolk. Last year it spent more than \u00a312 bil\u00adlion acqui\u00adring British Energy, the UK nuclear gene\u00adra\u00adtor, to secure access to them.<\/p>\n The French-designed EPR is the world\u2019s most power\u00adful nuclear reac\u00adtor. Each is capable of gene\u00adra\u00adting 1,600 mega\u00adwatts of elec\u00adtri\u00adci\u00adty\u200a\u2014\u200aenough to sup\u00adply a city of near\u00adly 2 mil\u00adlion people.<\/p>\n While two EPRs are being built in Finland and France, none is yet in ser\u00advice. The pro\u00adto\u00adtype EPR, at Olkiluoto in wes\u00adtern Finland, is run\u00adning three years late and bil\u00adlions of euros over budget.<\/p>\n The NII said that it would grant a licence for the EPR reac\u00adtor only if it was satis\u00adfied that the reac\u00adtor desi\u00adgn could be built and ope\u00adra\u00adted safe\u00adly and securely.<\/p>\n Finnish regu\u00adla\u00adtors rai\u00adsed ear\u00adlier concerns about the reactor\u2019s C&I sys\u00adtems but this is the first time that their British coun\u00adter\u00adparts have done so.<\/p>\n Areva and EDF are in talks with the NII about a revi\u00adsed desi\u00adgn. Areva said : \u201cThe group is com\u00admit\u00adted to ensu\u00adring the safe\u00adty of the EPR reac\u00adtor and to mee\u00adting the UK\u2019s spe\u00adci\u00adfic requi\u00adre\u00adments. The group is confi\u00addent that a solu\u00adtion can be defi\u00adned in the months to come.\u201d<\/p>\n EDF said safe\u00adty was the company\u2019s No 1 prio\u00adri\u00adty at all times.<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":" AFP - 1er juillet 2009 - LONDRES Les quatre r\u00e9ac\u00adteurs nucl\u00e9aires de type EPR que les groupes fran\u00ad\u00e7ais Areva et EDF se pro\u00adposent de construire au Royaume-Uni ont fait l\u2019objet de cri\u00adtiques des auto\u00adri\u00adt\u00e9s locales quant \u00e0 leur s\u00e9cu\u00adri\u00adt\u00e9, dans une lettre r\u00e9v\u00e9\u00adl\u00e9e mer\u00adcre\u00addi par le Times.
