Pedzisa mutsara unotevera: Kuita uku ndiko kwakakonzera tsaona duku yekuputika kwehydrogen yakatanga kuonekwa mukati mechivako chemuchina wokugadzira magetsi weThree Mile Island Nuclear Generating Station muna 1979 iyo isina kukuvadza chivako chokudzivirira. Mhinduro imwe chete iyi yakaitika mumvura inopisa 1, 2 uye 3 yeFukushima Daiichi Nuclear Power Plant (Japan) pashure pokunge kutonhora kwe reactor kwakambomiswa nemigumisiro yakafanana yechirwere.
kudengenyeka kwenyika uye tsunami zviitiko panguva yenjodzi yaKurume 11, 2011, zvichitungamira kunjodzi yenyukireya yeFukushima Daiichi. Gasi rehydrogen rakabudiswa muimba yokuchengetedza reactor uye musanganiswa unoputika wehydrogen nemhepo yeoxygen wakaputika. Kuputika kwacho kwakakuvadza zvikuru zvivako zvokunze uye chivako chimwe chete chokudzivirira. Mhinduro yacho yakaitikawo panguva yeChernobyl Accident, apo chiutsi chakabva murekita chakatanga kubuda. Zvivako zvakawanda zvinotonhorera nemvura zvine macatalyst-based passive autocatalytic recombiner units akaiswa kuti ashandure nokukurumidza hydrogen neoksijeni kuva mvura patembiricha yemukamuri kusati kwasvika muganhu wekuputika.
