Ukuthunyelwa kwakhona Imfazwe lulwaphulo-mthetho ngoJulayi 1, 2017.
Urhulumente wobumbano uye wasebenza ngokufihlakeleyo kwisicwangciso sokuthutha ulwelo olune-radioactive kakhulu ukusuka e-Chalk River, e-Ontario, eCanada, ukuya kwiSavannah River Site e-Aiken, SC - umgama ongaphezu kweekhilomitha ezili-1,100. Uthotho lweelori ezingama-250 zicwangciswe liSebe lezaMandla (DOE). I-Interstate 85 yenye yeendlela eziphambili.
Ngokusekelwe kwidatha epapashiweyo ye-Arhente yoKhuseleko lweNdalo yase-US, ii-ounces ezimbalwa zolu lwelo zinokutshabalalisa unikezelo lwamanzi lwesixeko sonke.
Oku kuthunyelwa kolwelo akuyomfuneko. Inkunkuma ye-radioactive inokudityaniswa phantsi-kwisiza, iyenze ibe sisiqina. Oku kwenziwe iminyaka eChalk River. Iirekhodi zexesha elidlulileyo zicace kakhulu malunga nolu lwelo kunye nendlela ekufuneka ilawulwe ngayo. Ingxelo "INkcazelo eNkcazelo malunga neNgqwalaselo yeNdalo ngeCandelo leMvume yeMpahla, iKhomishini yaMandla eAtomiki yase-US" (i-14 kaDisemba 1970) - engaphakathi kuyo isicelo se-Allied General se-Barnwell Nuclear Fuel Plant (iDokethi enguNombolo 50-332) - ichaza inkunkuma eyenziwa kweso sibonelelo, kwaye ichaza indlela yokulawula inkunkuma. Ndandiyazi le ngxelo ngenxa yomngeni ophumeleleyo wezomthetho kwesi sakhiwo ngeminyaka yee-1970 endandithatha inxaxheba kuyo. Nalu ulwandlalo lwemilinganiselo efunekayo:
- Qinisekisa ukuvalelwa ngokupheleleyo kwe-HLLW ngemiqobo emininzi (HLLW – “inkunkuma yolwelo ekwinqanaba eliphezulu”)
- Qinisekisa ukupholisa ukususa ubushushu bemveliso ezizivelisayo ngeenkqubo zokupholisa ezingafunekiyo
- Nika indawo eyaneleyo kwitanki yokugcina...
- Lawula umhlwa ngoyilo olufanelekileyo kunye namanyathelo okusebenza
- Lawula iigesi ezingacondensable kunye ne-airborne particulates, kubandakanywa ne-radiolytic hydrogen H2
- Gcina kwifom ukuququzelela ukuqina kwexesha elizayo
Uninzi lwezi alunakwenzeka ngexesha lokuthutha. Ukongezelela, xa oku kuphindwa izihlandlo ezingama-250, impazamo nje encinane, umntu okanye isixhobo, inokuba yintlekele. Kwaye iimpazamo zilindeleke. Ngokomzekelo, ekuthunyelweni kokuqala (kwaye kuphela ukuza kuthi ga ngoku), babenendawo eshushu kwisitya sothutho, kwaye kwiSavannah River Site kwafuneka bayijike ukuze bajongane nodonga, kucingelwa ukuba bangabavezi abasebenzi.
UMary Olson weNuclear Information Resource Service, omnye wabamangali kwisimangalo esichasene noku kuthunyelwa, uchaza ukuba “nangona kungekho kuvuza kokuqulethweyo, abantu baya kuchanabeka kwimitha ye-gamma eyingozi kunye nemitha ye-neutron eyonakalisayo ngokuhlala nje ezindleleni ecaleni kwenye ezi lori zothutho. Kwaye ngenxa yokuba ulwelo lune-uranium yomgangatho wezixhobo, kukho ithuba elihlala likhona lokusabela okuzenzekelayo okukhupha ukudubula okunamandla kweeneutron ezisongela ubomi macala onke - oko kubizwa ngokuba 'yingozi'.
Ngaphandle kwesimangalo, ngaphandle kwazo zonke iileta, ngaphandle kwe-imeyile, ngaphandle kwezikhalazo, ezivela kumawaka abemi abachaphazelekayo, i-DOE ithi impembelelo "ayibalulekanga." Nangona umthetho ufuna oko, i-DOE ayenzanga iNgxelo yeMpembelelo yokuSingqongileyo.
Kubekho inani elilinganiselweyo leendaba; ngoko ke, abantu abaninzi abanokuchatshazelwa yingozi abazi ukuba oku kuyenzeka.
Le nto kufuneka iyekwe. Nceda ucele iRhuluneli ukuba igcine ezi mpahla zithunyelwa ngaphandle kwelizwe.
