Dhulgariirkii 2011 iyo tsunami 15 + mitir ah oo ka dhashay xeebta bari ee Japan, warshadda korontada nukliyeerka ee Fukushima I ayaa waxyeelo soo gaartay saddex ka mid ah lixda reactors ka dib markii nidaamyada qaboojinta gargaarka degdegga ah ay ku fashilmeen sababo la xiriira xaaladaha aasaasiga ah ee ka baxsan naqshadeynta. Taasi waa, warshadihii Fukushima ma aysan tixgelin tsunami kor ku xusan naqshadooda asalka ah. Warshadahaani waxay ahaayeen General Electric BWR-3 iyo BWR-4 warshadaha gudaha Mark I naqshadaha xakamaynta, taas oo caan ku ah Mareykanka. Si kastaba ha noqotee, dhamaan noocyada dhirta waxay leeyihiin naqshado kaladuwan sababo la xiriira xeerarka, doorbidyada adeegsiga shaqsiyeed, iyo goobta dhismaha. Sanadkii 1995, Sandia National Laboratories waxay ku qiyaastay in shaqsiyaadka BWR-3 iyo BWR-4 ee Mareykanka ay leeyihiin inta jeer ee dhaawaca asaasiga ah inta udhaxeysa 10−4 iyo 10−7.
