Ibuyisiwe kusuka Impi Iwubugebengu ngoJulayi 1, i-2017.
Uhulumeni wobumbano ubesebenza ngasese ngohlelo lokuthutha uketshezi olunemisebe eminingi olusuka e-Chalk River, e-Ontario, eCanada, luye eSavannah River Site e-Aiken, SC - ibanga elingaphezu kwamamayela ayi-1,100. Uchungechunge lwamaloli angama-250 luhlelwe uMnyango Wezamandla (i-DOE). I-Interstate 85 ingenye yezindlela eziyinhloko.
Ngokusekelwe kudatha eshicilelwe ye-US Environmental Protection Agency, ama-ounces ambalwa alolu ketshezi angacekela phansi amanzi edolobha lonke.
Lokhu kuthunyelwa koketshezi akudingekile. Imfucuza ekhipha imisebe ingahlanganiswa phansi esizeni, iyenze ibe into eqinile. Lokhu sekwenziwe iminyaka e-Chalk River. Amarekhodi esikhathi esidlule acace bha mayelana nalolu ketshezi nokuthi kufanele luphathwe kanjani. Umbiko othi “Isitatimende Esiningiliziwe Ngokucatshangelwa Kwezemvelo Ngokuhlukaniswa Kwelayisense Yezinto Ezibalulekile, Ikhomishana Yamandla E-Atomic yase-US” (Disemba 14, 1970) - ngaphakathi kwawo unesicelo se-Allied General se-Barnwell Nuclear Fuel Plant (Idokodo No. 50-332) — ichaza udoti okhiqizwa kuleso sikhungo, futhi ichaza nendlela yokuphatha udoti. Ngangazi ngalo mbiko ngenxa yenselele eyimpumelelo yezomthetho kulesi sikhungo ngeminyaka yawo-1970 engangibambe iqhaza kuyo. Nali uhlaka lwemibandela edingekayo:
- Qinisekisa ukuvalelwa okuphelele kwe-HLLW ngezithiyo eziningi (I-HLLW - "imfucumfucu yezinga eliphezulu")
- Qinisekisa ukupholisa ukuze ususe ukushisa komkhiqizo ozidalela wona ngamasistimu wokupholisa angasebenzi
- Nikeza indawo eyanele ethangini lokugcina...
- Lawula ukugqwala ngedizayini efanele nezinyathelo zokusebenza
- Lawula amagesi angacondensable kanye nezinhlayiya ezihamba emoyeni, kuhlanganise ne-radiolytic hydrogen H2
- Gcina ngendlela ukuze wenze ukuqina kwesikhathi esizayo
Iningi lalokhu alinakwenzeka ngesikhathi sokuthutha. Ngaphezu kwalokho, lapho lokhu kuphindwa izikhathi ezingu-250, iphutha elincane nje, umuntu noma imishini, kungaba yinhlekelele. Futhi amaphutha kufanele alindelwe. Isibonelo, ekuthunyelweni kokuqala (futhi kuze kube manje kuphela), babenendawo eshisayo esitsheni sokuthutha, futhi eSavannah River Site kwakudingeka bajike ukuze babhekane nodonga, okucatshangwa ukuthi bangabavezi abasebenzi.
UMary Olson weNuclear Information Resource Service, ongomunye wabamangali ecaleni elimelene nalokhu kuthunyelwa, uyachaza ukuthi “ngisho nangaphandle kokuvuza kokuphakathi, abantu bazochayeka emisebeni ye-gamma eyingozi kanye nemisebe ye-neutron elimazayo ngokuhlala nje esiminyaminya eduze komunye lamaloli ezokuthutha. Futhi ngenxa yokuthi uketshezi luqukethe i-uranium yezinga lezikhali, kunethuba elihlala likhona lokusabela okuzenzakalelayo kweketanga elikhipha ukuqhuma okunamandla kwama-neutron asongela ukuphila kuzo zonke izinhlangothi—okubizwa ngokuthi ‘ingozi ebucayi’.”
Ngaphandle kwecala, naphezu kwazo zonke izincwadi, naphezu kwe-imeyili, naphezu kwezikhalazo, ezivela ezinkulungwaneni zezakhamizi ezithintekayo, i-DOE ithi umthelela "awubalulekile." Nakuba umthetho ukudinga, i-DOE ayizange yenze iSitatimende Somthelela Wezemvelo.
Kube nenani elilinganiselwe lokufakwa kwezindaba; ngakho-ke, abantu abaningi abangase bathinteke engozini abazi ukuthi lokhu kuyenzeka.
Lokhu kudinga ukumiswa. Sicela ucele uMbusi ukuthi agcine lokhu kuthunyelwa ngaphandle kwesifunda.
