Better than Inland OnesAAftertheevents of March11th2011,whenanearthquakeandtsunamiled to a meltdownof threenuclearreactorsattheFukushimaDai-ichi power plant in Japan,you might beforgivenfor concluding thatatomicpowerandseawaterdont mix.Manyengineers,though,do not agree.Theywould liketo see moreseawaterinvolved,notless.Infact,theyhave plans to site nuclearpower plants in theoceanratherfloatingon thesurface ormooredbeneath it.BAtfirst,thissoundsa madidea.Itis not.Land-basedpower stationsarebespoke(定制的)structures,builtbythe techniques of civilengineering,in which each is slightly differentand teamsof specialists come and goaccording to the phase of the project.Marinestations,bycontrast,could bemass-producedin factories using,ifnotthetechniques of theassembly line,thenatleastthoseof theshipyard,withcrewsconstantlyemployed.CThatwouldmake power stationsatsea cheaper thanthoseon landJacopoBuongiorno,a nuclearengineeratthe MassachusettsInstituteof Technology,reckons that,when all is doneanddusted,electricityfrom a marinestationwould cost at least a thirdless thanthatfrom a terrestrialequivalent.It would also make them safer.Areactoranchoredon the seabedwould never lackemergency cooling,the problem thatcaused the Fukushimameltdown.Norwould to beprotected againstthe riskofterroristsflying an aircraft into it.It would betsunami-proof,too.Though tsunamis becomegreatand destructive waveswhen they arrive in shallow betsunami-proof,too.Though tsunamisbecomegreat anddestructive waveswhen they arrive in shallow water,inthe openocean they aremereripples.Indeed,were it deepenough(100metresor so),such a submarine reactorwouldnoteven be affectedby passingstorms.DAllthese reasons,observes JacquesChenais,an engineer at FrancesAtomic-Energycommission,CEA,make underwater nuclearpower stationsanideaworthinvestigating.Dr.Chenais is headof smallreactorsatCEA,andhashadexperiencewithone well-establishedtype of underwater reactorthat powers submarines.Heandhisteamarenow assisting Naval Group,a French militarycontractor,to design reactorsthatwill stay put insteadofmovingaroundon a boat.Theplan is to encase(把围住)a reactorandanelectricity-generatingsteamturbineina steelcylinderthelength of a footballpitch andwitha weight of around12,000tonnes.EThewhole system,dubbedFlexblue,would beanchoredto the seabed between fiveand15kmfrom thecoastfar enough for safety in case of an emergency,butnear enough to beserviced easily.Theelectricitygenerated(upto 250 megawatts,enough for 1mpeople)wouldbetransmittedashorebyan underseacable.Forrefuelingandmaintenanceunmanageablefrom a submarine,the cylinderwould befloated to the surface with airinjected into its ballast tanks.And,when a station came to the end of its useful life,it could betowed to aspecialist facility to be dismantledsafely,ratherthanrequiringyet anotherlotof civil engineers to demolishit.FNaval Group has not,as yet,attracted any customers for its designs.But a slightly less ambitious approachto marine reactorsanchoring them on the surface rather than below itis about to come to fruition(实现)inRussia.The first such,Akademik Lomonosov,is under construction at the Baltic Shipyard,in St.Petersburg.According to Andrey Bukhovtsev of Rosatom,the agency that runs Russias civil nuclear program,it is 96%complete.It will be launched later this year,towed to Murmansk,and thence transported to Pevek,a port inRussias Far East,where it will begin generating power in 2019.GAkademik Lomonosov consists of two 35MW reactors mounted on a barge.The reactors are modifiedversions of those used to power Taymyr-class icebreakers.As such,they are designed to be able to take quite abattering,so the storms of the Arctic Ocean should not trouble them.To add to their safety,the barge bearing themwill be moored,about 200 metrs from shore,behind a storm-and-tsunami-resistant breakwater.HAltogether,Akademik Lomonosov will cost$480m to build and installfar less than would have to bespent constructing an equivalent power station on land in such a remote and hostile environment.And,on thepresumption that the whole thing will work,plans for a second,similar plant are being laid.I Nor is Russia alone in planning floating reactors.China has similar ambitions.Specifically,the Chinesegovernment intends,during the 2020s,to build up to 20 floating nuclear plants,with reactors as powerful as200MW,to supply artificial islands it is building as part of its plan to enforce the countrys claim to much of theSouth China Sea.JThe firms involved in this project intend to tsunami-proof some of their reactors in the same way as theFrench,by stationing them in water too deep for massive tsunami waves to form.Because they are at the surface,though,that will not save them from stormsand locating them far from shore means the Russian approach ofbuilding sheltering breakwaters will not work either.That matters.Typhoons in the South China Sea can whip upwaves with an amplitude enceeding 20 metres.KTo withstand such storms,the barges will have anchors that are attached to swiveling“mooring turrets”under their bows.These will cause a barge to behave like a weather vane,always pointing into the wind.Since thatis the direction waves come from,it will remain bow-on to those waves,giving it the best chance of riding out anystorm that nature cares to throw at it.The bargesbows will also be built high,in order to cut through waves.Thisway,claims Mark Tipping of Lloyds Register,a British firm that is advising on the plants design,they will beable to survive a“10,000-year storm.”LThe South China Sea is also a busy area for shipping,so any floating power stations there will need to beable to withstand a direct hit by a heavy-laden cargo vessel travelling at a speed of,say,20knotswhether thatcollision be accidental or the result of hostile action.One way to do this,says Chen Haibo,a naval architectworking on the problem at Lloyds Registers Beijing office,is to fit the barges with crumple zones packed withmaterials such as corrugated steel and wood.MNot everyone is delighted with the idea of marine nuclear power.Rashid Alimov,head of energy projectsat Greenpeace Russia,an environmental charity,argues that offshore plants could be boarded by pirates orterrorists,be struck by an iceberg or might evade safety rules that are hard to enforce at sea.On July 21stGreenpeace scored a victory when Rosatom said that Akademik Lomonosovs nuclear fuel would be loaded in anunpopulated area away from St.Petersburg.NThat,though,is a pinprick(小范围).The future of marine nuclear power stations is more likely to dependon the future of nuclear power itself than on the
