Authors Jerry Havens and Collis Geren draw upon this history to assess the accidental explosion risk inherent in using fast reactors to reduce the energy industry's carbon dioxide emissions.If a sufficiently powerful fast-neutron explosion were to cause the containment of a reactor such as SEFOR's to fail, the reactor's radiotoxic plutonium fuel could vaporize and escape into the surrounding environment, resulting in a miles-wide swath of destruction. The demonstration that the Doppler effect could prevent limited runaway reactivity in the event of an accident or natural disaster proved a critical development in producing safe nuclear technology. But while SEFOR was hailed as a breakthrough in nuclear safety, Havens and Geren's examination of the project, including the partial SCRAM that occurred in late 1970, confirms experts' concerns regarding the limits of the Doppler effect and presents a compelling argument for caution in adopting fast reactors like SEFOR to reduce carbon emissions. 517 $aThin Safety Margin 606 $aSodium cooled reactors$zArkansas 606 $aLiquid metal fast breeder reactors$zArkansas 610 $aScience: general issues 615 0$aSodium cooled reactors 615 0$aLiquid metal fast breeder reactors 700 $aHavens$b Jerry A$01431610 701 $aGeren$b Collis$01217920 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910504286003321 996 $aThin Safety Margin$93574230 997 $aUNINA
