Kunyanya, chiedza chakaratidzira chakavanzika chakatungamirira kumunhu anoshanda nemaoko anodzvinyirira hurongwa hwekudzivirira kutonhora kweiyo reactor nokuti mushandi akafunga zvisiri izvo kuti pakanga pane mvura yakawanda inotonhorera iripo mu reactor uye inokonzera kusunungurwa kwemhepo yemhepo. Kukura uye kuoma kwakaita tsaona yacho kwakava pachena mumazuva mashanu, sezvo vashandi veMet Ed, vakuru vehurumende yePennsylvania, uye nhengo dzeU.S. Nuclear Regulatory Commission NRC vakaedza kunzwisisa dambudziko racho, kutaura mamiriro acho ezvinhu kune vezvenhau uye munharaunda, kusarudza kana tsaona yacho yaida kubviswa kwechimbichimbi, uye pakupedzisira kugumisa dambudziko racho.
