Isigameko seNyukliya eNorth's Worst
Ngo-Mashi 28, 1979, iMelika yabona ingozi yakho enamandla kunazo zonke - ukuqubuka okuyingxenye yomgogodla we-reactor at the Three Mile Island plant nuclear power near Middletown, Pennsylvania. Ngesikhathi seviki elinezinkinga ezilandelanayo, imibiko ye-sketchy kanye nolwazi oluphikisanayo kwaholela ekwethukeni, futhi izakhamuzi ezingaphezu kwekhulu eziyikhulu, ikakhulukazi izingane nabesifazane abakhulelwe, babaleka endaweni.
- Ekuqaleni kukaMashi 28, amaphampu amaningana aphefumula amanzi ahluleka ku-reactor yesibili e-Three Mile Island (TMI-2), okwenza lokhu kusetshenziswe.
- Isisombululo sivale phansi imizuzwana eyisishiyagalombili kamuva, kodwa izinga lokushisa eliyisisekelo laqhubeka likhuphuka ngoba ama-valves alawula amanzi okupholisa okuphuthumayo ayevaliwe.
- Ngemva kwamahora ayishumi nesithupha, umgogodla wafika ekukhukhuleni futhi izinga lokushisa lalo lilawulwa phansi. Ngalesi sikhathi, isigamu se-core sasincibilikile, kanti ingxenye yaso yayisakazeke, nakuba kwakuyiminyaka ngaphambi kokuba ososayensi bathole ukuthi ukuqubuka kwenzeka. I-TMI-2 ibesebenza kuphela izinsuku ezingu-90 lapho kwenzeka ingozi.
- Ngomhlaka-30 Mashi, kamuva okwaziwa ngokuthi "uLwesihlanu uLwesihlanu," amahemuhemu asakazwa ngokukhululwa kwemisebe engalawuleki esivela esitshalweni kanti umbusi wasePennsylvania wayala ukukhululwa kwezingane nabesifazane abakhulelwe abahlala emakhilomitha angu-5 esitshalweni. Kamuva, kwafundwa ukuthi ukukhululwa kwakuhlelwe ukunciphisa ukucindezela ngaphakathi kwesistimu.
- Ngo-Ephreli 2, 1979, izinsuku ezinhlanu emva kokuqubuka, inhlekelele e-Three Mile Island yabizwa ngokusemthethweni ukuthi iphelile.
- Nakuba ukuquketwa kwe-TMI-2 kubanjwe futhi kukhishwe izinto ezincane zokusakaza i-radioactive, lo mkhiqiza wawungcolile kakhulu. Akekho ongangena esitshalweni iminyaka emibili.
- Isakhamuzi se-TMI-2 ekugcineni safakwa ekukhoneni futhi i-TMI-1 yaqala kabusha ngo-1986.
Impact ye-Three Mile Island Disaster
Inhlanganisela yokuhluleka kwemishini, iphutha lomuntu, nenhlanhla, ingozi yenyukliya e-Three Mile Island yahlaba umxhwele isizwe futhi yashintsha ngokuphelele imboni yenukliya eMelika.
Nakuba kungabangela ukufa noma ukulimala ngokushesha ukutshala izisebenzi noma amalungu omphakathi oseduze, ingozi ye-TMI yaba nethonya elibi embonini yamandla enyukliya - iKhomishini yeNuclear Regulatory ayizange ibuyekeze isicelo sokwakha isitshalo samandla enyukliya entsha i-United States kusukela. Kwaletha nezinguquko ezishintshayo ezibandakanya ukuhlela ukubhekana nezimo eziphuthumayo, ukuqeqeshwa komqhubi we-reactor, izici zobunjiniyela bomuntu, ukuvikelwa kwemisebe, nezinye izindawo eziningi zokusebenza kwamandla enyukliya.
Imiphumela Yempilo ye-Three Mile Island
Ucwaningo oluningi ngemiphumela yezempilo, kuhlanganise nocwaningo olwenziwa ngo-2002 olwenziwa yiYunivesithi yasePittsburgh, selinqume umthamo wesilinganiso semisindo kubantu ababeseduze neThathu Mile Island ngesikhathi sokuqubuka kwakuyi-1 millirem - okungaphansi kwesilinganiso, ngonyaka umthamo wabahlali base-Pennsylvania central. Eminyakeni engamashumi amabili nanhlanu kamuva, akubanga nokukhula okuphawulekayo komdlavuza wokufa phakathi kwabahlali abahlala eduze nendawo yeThathu Mile Island. Ukuhlaziywa okusha kwezibalo zezempilo esifundeni esenziwa yi-Radiation and Project Health Project, Nokho, bathole ukuthi izinga lokufa kwabantwana, abantwana, kanye nabakhulile lakhuphuka eminyakeni emibili yokuqala ngemva kwengozi yeThathu Mile Island eDauphin nasezindaweni ezizungezile .
I-Three Mile Island Namuhla
Namuhla, i-reactor TMI-2 ivalwe unomphela futhi ichithekile, isistimu epholile yokucubungula igcwele amanzi, amanzi aphikisayo ahlambalaza futhi ashubile, udoti olusakazwa yi-radioactive oluhanjiswa ngaphandle kwesayithi kuya endaweni efanelekile yokulahla, uphethiloli we-reactor, kanye ne-core debris ethunyelwe ngaphandle kuya eMnyangweni wezeMandla, kanti okunye okusele kusayiniwe. Ekuqaleni, kwakukhona inkulumo yokudiliza i-Unit 2 lapho ilayisensi yayo iphela ngo-Ephreli 2014, kepha izinhlelo ezihanjiswe ngo-2013 yi-FirstEnergy, ene-Unit 1, manje ibiza "ukudiliza i-Unit 2 ehamba phambili kanye ne-Unit 1 lapho ilayisensi yayo iphelelwa yisikhathi ngo-2034. " Ukudilizwa kuzokwenzeka esikhathini esiyiminyaka eyishumi, nokubuyiselwa kabusha kwezaziso ngeminyaka engu-2054 - 75 ngemuva kwengozi.
