42CrMo Simba Rakaputirwa neChromium Shaft Yakasimba Yakavhara Chrome Tsvimbo Yakagadzirwa Nesimbi YeMichina
Chepetsk Mechanical Plant (CMP), chikamu cheTVEL Fuel Division yeRosatom State Corporation, yakagadzira nzvimbo yekuedza yekugadzira mota dzemagetsi. jira remafuta rakaputirwa nechromium. Chivako ichi mhinduro yakanaka pakugadzira mafuta emhando yepamusoro echizvarwa chinotevera (AF). Chinovandudza kuvimbika kwekushanda kwemafuta enyukireya, nokudaro zvichiwedzera kuchengetedzeka nekushanda zvakanaka kwema reactors.
Kuti vagadzire jira idzva rekuisa mafuta mumatanda, ChMZ yakapa nzvimbo yekuisa chromium-platting yejira rekare rekuisa zirconium alloy. Kuvhara kwekudzivirira kunoiswa zvakananga pamachubhu marefu ezirconium uchishandisa nzira yekupfapfaidza. Pamusoro pezvo, michina yemazuva ano yekuongorora nekutsvaga yakapihwa basa rekuongorora kunamira, chimiro, uye ukobvu hwe chromium coating, iyo inogona kushandiswa pakugadzira uye kutsvagisa mukugadzira zvigadzirwa zvitsva. Batch yekutanga ye chromium-plated fuel rod cladding yakagadzirwa.
Alexander Ugryumov, Mutevedzeri Mukuru weSainzi neTechnical Activities kuTVEL, akati: "Kubva mugore ra2021, maATF fuel assemblies matatu akagadzirwa muRostov NPP's VVER-1000 reactors. VVER-1000 assemblies yega yega ine 312 fuel elements. Kuitwa kweChMZ chromium-plated fuel element production plant kuchagonesa kugadzirwa kweATF fuel assemblies dzakawanda. Kuitwa kweATF fuel assemblies idzi mu high-power reactors kucharatidza danho rekupedzisira rekugadzirwa kweATF fuel muRussia uye danho rekupedzisira rekufanirwa uye rekuita sarudzo."
Sergey Chineikin, Mutungamiriri Mukuru weRussian Nuclear Fuel Reprocessing Center, akataura kuti kutora chikamu mukutsvaga nekuvandudza matekinoroji matsva ekugadzira mafuta enyukireya kwakakosha zvikuru kunzvimbo iyi. Akati, "Kuunzwa kwemidziyo mitsva yemuno yemhando yepamusoro yekushandisa machira ekudzivirira mumidziyo yemafuta uye kugadzira zvigadzirwa zvakachengeteka kuchaita kuti mafuta enyukireya eRussia akwikwidzane mune ramangwana mumusika wepasi rose."
Sangano reNational Research Institute of Atomic Reactors (NIIAR) riri muDimitrovgrad parizvino riri kuita ongororo yakakura. bvunzochirongwa chekuyedza paMIR research reactor, kusanganisira kuyedza zvinhu zvakasiyana-siyana zvekufukidza mafuta uye mapellet emafuta eATF. Muna 2022, chirongwa ichi chakawedzerwa kuti chibatanidze kuyedzwa kwetsvimbo itsva dzemafuta neuranium silicide-based fuel yeVVER uye mareactor emvura ane pressurized. Kubva muna 2021, kushanda kwekuyedza kwezvikamu zvitatu zvemafuta zvakabatana netsvimbo dzemafuta eATF kwave kuri kuitwa paRostov NPP's VVER-1000 reactor. Zvinhu zvekuvaka zvinoshandiswa i42KhNM chromium-nickel alloy kana chromium-plated zirconium alloy.
