Ingozi yeNyukliya enkulu kunazo zonke
Ngomhla wama-28 Matshi 1979, iMelika yabona ingozi yenyukliya eyona nto yimbi kakhulu - ingxowankulu ye-reactor core kwi-Three Mile Island isityalo samandla enyukliya ngaseMiddletown, ePennsylvania. Ngexesha leveki ephazamisekile elandelelanayo, iingxelo zeengqungquthela kunye nolwazi oluphikisanayo lubangela ukwethuka, kunye nabemi abangaphezu kwekhulu lamawaka, ikakhulukazi abantwana kunye nabasetyhini abakhulelweyo, babaleka kuloo ndawo.
- Ekuqaleni kwangoMatshi 28, amaphampu amancinci amancinci amanzi aphumelelanga kwi-reactor yesibili kwi-Three Mile Island (TMI-2), ebangela ukuba i-reactor isonge.
- I-reactor ivale yona phantsi kwemizuzwana yesibhozo kamva, kodwa ukushisa okusemgangathweni kwaqhubeka kuphakama kuba iiguvayi ezilawula ukuphucula amanzi okuphuthuma zavalwa.
- Kwiiyure ezilishumi elinesibhozo kamva, intloko yagqitywa kwaye iqondo lokushisa lilawulwa phantsi. Ngalesi sikhathi, isiqingatha senkqantosi sincibilike, kwaye inxalenye yaso yayichithekile, nangona bekuyiminyaka ngaphambi kokuba izazinzulu zifumene ukuba kukho ukuphazamiseka. I-TMI-2 yayisetyenziswa kuphela iintsuku ezingama-90 xa kwenzeka ingozi.
- Ngomhla wama-30 ku-Matshi, kamva kuthiwa yi "Black Friday," iindlebe zazisasazwa ngokukhululwa okungalawulwayo kwemitha evela kwisityalo kunye ne-rhu runeli yasePennsylvania yayalela ukukhutshwa kwabantwana kunye nabasetyhini abakhulelweyo abahlala kwiimitha ezili-5 zityalo. Kamva, kwafunyanwa ukuba ukukhululwa kwakucetywe ukunciphisa uxinzelelo ngaphakathi kwenkqubo.
- Ngomhla ka-Aprili 2, 1979, iintsuku ezintlanu emva kokuphazamiseka, inzima kwi-Three Mile Island yavakaliswa ngokusemthethweni ukuba iphelile.
- Nangona i-TMI-2 izithintelo ezigcinwe kunye nezinto ezincinci zokusasaza, i-reactor yayingcolile kakhulu. Akukho mntu unokungena kwisityalo iminyaka emibini.
- I-reactor TMI-2 ekugqibeleni yafakwa kwikhonkrithi kwaye i-TMI-1 yaqala kwakhona ngo-1986.
Impembelelo yeSixeko seThathu Mile Island
Ukuhlanganiswa kwezixhobo ezingaphumeleliyo, iimpazamo zabantu kunye nenhlanhla, ingozi yenyukliya kwiThathu Mile Island yancinca isizwe kwaye yatshintsha ngokusisigxina imboni yenyukliya eMelika.
Nangona iholele ekungabikho kokufa okanye ukulimala ukutshala abasebenzi okanye amalungu asekuhlaleni, ingozi ye-TMI inefuthe elibhubisayo kwi-shishini lamandla enyukliya-iKomishoni yokuLawula iNyukliya ayizange ihlaziye isicelo sokwakha isityalo esitsha samandla enyukliya eUnited States ukususela. Kwakhona kwazisa utshintsho oluthile olubandakanya ucwangciso lweempendulo, ukuqeqeshwa kwabasebenzi bama-reactor, izinto zobunjineli, ukukhuselwa kwemisebe, kunye nezinye iindawo zokusebenza kwamandla enyukliya.
Iimiphumo zeMpilo ze-Three Mile Island
Izifundo ezahlukeneyo ngeziphumo zempilo, kubandakanywa nophando olwenziwa ngo-2002 oluqhutywa yiYunivesithi yasePittsburgh, liye lagqiba umlinganiselo wesilinganiso sombane kubantu abathile kufuphi ne-Three Mile Island ngexesha lokuchithwa kwaba malunga ne-1 millirem - ngaphantsi komyinge, wonyaka, wemvelo idosi kubantu abahlala kwiphondo lasePennsylvania. Kwiminyaka engamashumi amabini anesihlanu emva koko, akubangakho ukuphakama okuphawulekayo kumdlavuza wesi sifo phakathi kwabahlali abahlala kufuphi ne-Three Mile Island site. Uhlalutya olutsha lweemali zengingqi kummandla oqhutyelwa yiMivuzo kunye neProjekthi yezeMpilo kaRhulumente, kodwa ke, yafumanisa ukuba izinga lokufa kwabantwana, abantwana kunye nabalupheleyo benyuke kwiminyaka emibili yokuqala emva kweengozi yeThathu Mile Island eDauphin kunye neendawo ezikufutshane .
I-Three Mile Island namhlanje
Namhlanje, i-reactor TMI-2 igxininiswa ngokusisigxina kwaye ichithwe, kunye ne-reactor i-systemant coolant, i-radioactive water disontaminated and evaporated, i-wasteactive discharge site-site kwindawo efanelekileyo yokulahla, i-reactor fuel, kunye ne-debris ekhutshwe kuyo kwiSebe leZibonelelo zamandla, kwaye intsalela yesayithi ihlolwe. Ekuqaleni, kwakukho intetho yokuchithwa kweNyunithi yesi-2 xa ilayisenisi yayo iphelelwa ngo-Ephreli 2014, kodwa izicwangciso ezithunyelwe ngo-2013 yi-FirstEnergy, eneCandelo 1, ngoku libiza "ukutshabalalisa iCandelo 2 leCandelo le-Operational Unit xa ilayisensi yayo iphelelwa ngowe-2034. " Ukuchithwa kwemali kwakuza kwenzeka ngexesha elishumi lonyaka, ngokubuyiselwa indawo epheleleyo ngo-2054 ukuya kuma-75 emva kwengozi.
