Induku Eqinile Ene-Chrome Ene-Chromium Ene-42CrMo Yemishini Yemishini

I-Chepetsk Mechanical Plant (CMP), eyingxenye ye-TVEL Fuel Division ye-Rosatom State Corporation, isungule indawo yokukhiqiza yokuhlola ye- ukumbozwa kukaphethiloli okumbozwe nge-chromium. Le nto yokwakha iyisisombululo esithembisayo sokukhiqizwa kukaphethiloli othuthukisiwe wesizukulwane esilandelayo (AF). Ithuthukisa ukuthembeka kokusebenza kukaphethiloli wenuzi, ngaleyo ndlela ithuthukise ukuphepha nokusebenza kahle kwama-reactor.

Ukuze kukhiqizwe ukumbozwa kwenduku kaphethiloli okusha, i-ChMZ iqalise isikhungo sokufaka i-chromium ukuze kumbozwe i-zirconium alloy yendabuko. Isembozo esivikelayo sisetshenziswa ngqo kumashubhu amade e-zirconium kusetshenziswa indlela yokufafaza. Ngaphezu kwalokho, imishini yesimanje yokuhlaziya nokucwaninga ithunywe ukuhlola ukunamathela, isakhiwo, kanye nobukhulu besembozo se-chromium, esingasetshenziswa kokubili ngezinjongo zokukhiqiza kanye nocwaningo ekuthuthukisweni kwemikhiqizo emisha. Kukhiqizwe iqoqo lokuhlola lesembozo senduku kaphethiloli esine-chromium.

U-Alexander Ugryumov, iPhini likaMongameli Omkhulu Wemisebenzi Yesayensi Nezobuchwepheshe kwa-TVEL, waphawula: "Kusukela ngo-2021, kusetshenziswe izinhlangano ezintathu zikaphethiloli ze-ATF kuma-reactor e-VVER-1000 e-Rostov NPP. Izinhlangano ngayinye ye-VVER-1000 iqukethe izakhi zikaphethiloli ezingu-312. Ukuqaliswa kwesitshalo sokukhiqiza izakhi zikaphethiloli ezifakwe i-chromium ye-ChMZ kuzokwenza kube lula ukukhiqizwa kwezinhlangano eziningana eziphelele zikaphethiloli we-ATF. Ukuqaliswa kwalezi zinhlangano kuma-reactor anamandla amakhulu kuzophawula isigaba sokugcina sokukhiqizwa kukaphethiloli we-ATF wezimboni eRussia kanye nesigaba sokugcina sokufaneleka kanye nokwenza izinqumo."

USergey Chineikin, uMqondisi Jikelele we-Russian Nuclear Fuel Reprocessing Center, uthe ukubamba iqhaza ocwaningweni nasekuthuthukisweni kobuchwepheshe obusha bokukhiqiza uphethiloli wenuzi kubaluleke kakhulu kulesi sikhungo. Uphawule ukuthi, "Ukwethulwa kwemishini yasekhaya emisha, enobuchwepheshe obuphezulu yokufaka izembozo zokuvikela emikhumbini kaphethiloli nokukhiqiza imikhiqizo ephephile kuzoqinisekisa ukuncintisana kwesikhathi esizayo kukaphethiloli wenuzi waseRussia emakethe yomhlaba wonke."

I-National Research Institute of Atomic Reactors (NIIAR) eDimitrovgrad okwamanje yenza ucwaningo olukhulu ukuhlolwaUhlelo lokuhlola e-MIR research reactor, okuhlanganisa nokuhlola izinto ezahlukene zokumboza uphethiloli kanye nama-pellet kaphethiloli e-ATF. Ngo-2022, lolu hlelo lwandiswa ukuze lufake ukuhlolwa kwe-in-reactor kwezinduku zikaphethiloli ezintsha ezinophethiloli osuselwe ku-uranium silicide we-VVER kanye nezi-reactor zamanzi ezicindezelwe. Kusukela ngo-2021, ukusebenza kokuhlola kwezinhlangano ezintathu zikaphethiloli ezihlanganisiwe nezinduku zikaphethiloli ze-ATF bekulokhu kuqhubeka e-Rostov NPP's VVER-1000 reactor. Izinto zokwakha ezisetshenziswayo yi-42KhNM chromium-nickel alloy noma i-chromium-plated zirconium alloy.

Ngiyavuma ukuthi i-Verdict Media Limited iqoqe idatha engiyinikezayo ngaleli fomu ngokuhambisana nenqubomgomo yayo yobumfihlo.
