<prompt> Ngo-March 28, 1979, ukwehluleka kwemishini nephutha lomqhubi kwabangela ukulahleka kuketshezi olupholisayo nokuncibilika okuyingxenye kwenhliziyo ye- Three Mile Island Nuclear Power Plant  <response>: ePennsylvania. Ukwehluleka kwemishini kwahlanganiswa ukwehluleka kokuqala kwabaqhubi bezitshalo ukubona isimo njengengozi yokulahleka kokupholisa ngenxa yokuqeqeshwa okunganele kanye nezici zabantu, njengokunganakwa kokuklanywa kokuxhumana komuntu nekhompyutha okuhlobene nezinkomba ezingacacile zegumbi lokulawula esibonakalayo somsebenzisi sesitshalo samandla. Ikakhulukazi, isibani esibonisayo esifihliwe saholela ekubeni opharetha abeke eceleni ngesandla uhlelo oluzenzakalelayo lokupholisa oluphuthumayo lwe-reactor ngoba opharetha wayekholelwa ngephutha ukuthi kwakukhona amanzi amaningi okupholisa akhona ku-reactor futhi abangela ukukhishwa kwengcindezi yomhwamuko. Ububanzi nobunzima bale ngozi kwacaca phakathi nezinsuku ezinhlanu, njengoba izisebenzi zeMet Ed, izikhulu zombuso wasePennsylvania, namalungu e-U.S. Nuclear Regulatory Commission NRC bezama ukuqonda le nkinga, ukuxhumana nesimo kwabezindaba nomphakathi wendawo, ukunquma ukuthi ingozi idinga ukususwa okuphuthumayo, futhi ekugcineni iqede le nkinga. Ukugunyaza kwe - NRC ukukhipha amalitha angu - 40 000 amanzi angcolile anemisebe ngokuqondile eMfuleni iSusquehanna kwaholela ekulahlekelweni ukwethenjwa abezindaba nomphakathi.
