I-IG ibika ukuthi kunezingxenye 'eziwumgunyathi' eziningi ezikhungweni zamandla enuzi zase-US kunalokho ezaziwa

Esithombeni i-valve yesango elingumbombayi le-Walworth elingaphandle kwencazelo enama-valve angempela amabili nhlangothi zombili. Iningi, uma kungezona zonke, izimboni zamandla enyukliya zase-US ziqukethe izingxenye eziwumgunyathi, eziwumgunyathi nezingabazekayo, ngokwemibiko emibili ekhishwe yiHhovisi Lomhloli Jikelele weKhomishini Yokulawula Yenuzi yase-US. amaphrojekthi wezinsiza zesikhathi esizayo. Umbiko we-IG uthi izingxenye eziwumgunyathi maningi amathuba okuthi zingaphumeleli, okuholela ezinkingeni ezingaba khona zokuphepha. Nakuba ukuhlaziya kuphakamise ukuthi i-NRC ichaze leli gama ngokucace kakhudlwana, uphenyo lwakhomba amakhophi angagunyaziwe ezingxenye zangempela, mhlawumbe ngezinhloso zokukhohlisa.Ngokusho kwe-Electric Power Research Institute, izingxenye eziwumgunyathi zitholakale ezindaweni zezitshalo okunzima ukuzithola njengama-valve. kanye nama-bearings nensimbi yesakhiwo.Ngisho nezingxenye ze-elekthronikhi njengama-circuit breaker ziya ngokuya zingomgunyathi. Kube khona amacala ambalwa abhaliwe okukhwabanisa kwengxenye kusukela ngo-2016, namaqembu emboni yezikhali zenuzi ahlonza amacala angaba ngu-10 angaba yizingxenye. Kodwa ngokusho kokuhlaziywa kwe-IG, inani langempela lingase libe likhulu kunenombolo eyaziwayo, njengoba amafektri ngokuvamile adingeka kuphela ukubika ku-NRC ezimweni ezibucayi, njengokwehluleka kwemishini yokuphepha ebalulekile.Noma kunjalo, abaphenyi be-IG abakwazanga ukunikeza inani elithile lezehlakalo zezingxenye zomgunyathi, ukusola amazinga axegayo wokubika ngamalayisensi esikhungo samandla enuzi. Kwesinye isigameko esiqokonyiswe embikweni, umgodi wephampu womgunyathi waphuka ngemva kwesikhathi esifushane sokusetshenziswa endaweni yokuphehla ugesi engashiwongo. Umphathi wokuthobela wesikhungo, nokho, akazange abike ku-NRC ngoba izidingo zokubika zisebenza kuphela ezingxenyeni ezisebenzayo. Kwesinye isigameko, amathuluzi asetshenziswa ukuhlonza imigqa yesimusi ephukile "ayenyuke kakhulu amanani okuhluleka," okungenzeka ngenxa yezingxenye ezinesici ezisetshenziswa ekulungiseni, kusho i-IG. Izingxenye eziwumgunyathi zazisolwa, kodwa abaphenyi abakwazanga ukuqinisekisa lokhu ngoba ulwazi oluncane lwalutholakala mayelana ukulungiswa okwenziwe eminyakeni eminingana futhi akukho mbiko odingekayo. Umbiko wesibili we-IG uhlongoza izenzo ezinconywe yi-NRC zokuqinisekisa ukuthi izimboni zamandla enuzi zinganciphisa ubungozi bezingxenye eziwumgunyathi kuma-reactors asebenzayo kanye nalezo ezisalungiswa.Kunconywe umqondisi omkhulu we-ejensi uDaniel Dorman, oqokwe esikhundleni ngo-Okthoba odlule, aziphathe. ukulungiswa kabusha kohlelo nokuthuthukisa inqubo yokuthi ikomidi liqoqe futhi labelane ngolwazi lwezingxenye eziwumgunyathi. I-IG icele u-Dorman ukuthi abelane ngolwazi nganoma yiziphi izenzo ezihleliwe ezihlobene nezincomo zingakapheli izinsuku ezingama-30. Esitatimendeni, uMhloli Jikelele we-NRC uRobert Fettel uthe bekungokokuqala ukuthi izigaba zayo zokucwaninga nokuhlola zibambisane kuleli zinga, futhi kuwuphawu lwezinguquko ekomitini. "Le mibiko ebanzi iyisibonelo esisodwa senkathi entsha [ye-IG] lapho ithimba lethu elinekhono labacwaningi mabhuku nabaphenyi lizoqhubeka nokusebenza ndawonye ngendlela edidiyelwe ukuze sifeze umgomo wethu wokuqinisekisa ubuqotho, ukusebenza kahle nokusebenza ngempumelelo kocwaningomabhuku lwe-NRC , "Uthe. Ithimba lezohwebo kule mboni, iNuclear Energy Institute, esitatimendeni lithe "lisabuyekeza lokho okutholakele" kodwa lathi "imboni inezinhlelo eziqinile nezibanzi zokuqinisekisa ukusebenza okuphephile kwezingxenye zezitshalo, okuhlanganisa nokusetshenziswa kweziqu ezisemthethweni. .izinqubo zokuhlinzeka, izimfuneko zokuqinisekisa ikhwalithi yabahlinzeki, ukuthembela kuma-OEM, nezilawuli eziqinile zokuthenga nokunakekela.” Iqembu lithe "lizibophezele ekusebenzeni ne-NRC njengoba libuyekeza lokhu okutholakele." Okuqukethwe okuxhasiwe kuyisigaba esikhokhelwayo esikhethekile lapho izinkampani zemboni zihlinzeka ngokuqukethwe kwekhwalithi ephezulu, okunenjongo, okungekona okokuhweba ngezihloko ezithakaselwa izethameli ze-ENR.Konke okuqukethwe okuxhasiwe kunikezwa izinkampani zokukhangisa.Unentshisekelo yokubamba iqhaza esigabeni sethu sokuqukethwe okuxhasiwe?Xhumana nasendaweni yangakini ummeleli.
