42CrMo Lub Zog Siab Chromium-Plated Ncej Hard Hollow Chrome Plated Qws rau Cov Khoom Siv Kho Tshuab

Lub Hoobkas Chepetsk Mechanical Plant (CMP), ib feem ntawm TVEL Fuel Division ntawm Rosatom State Corporation, tau tsim tsa lub chaw tsim khoom sim rau chrome plated fuel claddingCov khoom siv no yog ib qho kev daws teeb meem zoo rau kev tsim cov roj tshiab (AF) rau tiam tom ntej. Nws txhim kho kev ntseeg siab ntawm cov roj nuclear, yog li ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo ntawm cov reactors.

Txhawm rau tsim cov khoom siv tiv thaiv roj tshiab, ChMZ tau ua haujlwm rau lub chaw ua haujlwm chromium-plating rau cov khoom siv zirconium alloy ib txwm muaj. Cov txheej tiv thaiv no tau siv ncaj qha rau cov raj zirconium ntev siv txoj kev txau. Tsis tas li ntawd, cov khoom siv niaj hnub thiab kev tshawb fawb tau raug xaiv los soj ntsuam qhov kev nplaum, cov qauv, thiab qhov tuab ntawm cov txheej chromium, uas tuaj yeem siv rau kev tsim khoom thiab kev tshawb fawb hauv kev tsim cov khoom tshiab. Ib pawg sim ntawm cov roj chromium-plated cladding tau tsim tawm.

Alexander Ugryumov, Tus Lwm Thawj Coj Saib Xyuas Kev Tshawb Fawb thiab Kev Ua Haujlwm ntawm TVEL, tau hais tias: Txij li xyoo 2021 los, peb lub rooj sib dhos roj ATF tau raug siv rau hauv Rostov NPP's VVER-1000 reactors. Txhua lub rooj sib dhos VVER-1000 muaj 312 lub ntsiab lus roj. Kev ua haujlwm ntawm lub Hoobkas tsim cov ntsiab lus roj ChMZ chromium-plated yuav ua rau muaj ntau lub rooj sib dhos tiav ntawm ATF roj. Kev ua haujlwm cov rooj sib dhos no hauv cov reactors muaj zog siab yuav cim qhov kawg ntawm kev tsim roj ATF hauv kev lag luam hauv Russia thiab qhov kawg kev tsim nyog thiab kev txiav txim siab.

Sergey Chineikin, Tus Thawj Coj ntawm Lavxias Nuclear Fuel Reprocessing Center, tau hais tias kev koom tes hauv kev tshawb fawb thiab kev txhim kho ntawm cov thev naus laus zis tshiab ntawm kev tsim roj nuclear yog qhov tseem ceeb rau lub chaw. Nws tau hais tias, "Kev qhia txog cov khoom siv hauv tsev tshiab, siv thev naus laus zis siab rau kev siv cov tshuaj tiv thaiv rau cov roj thiab tsim cov khoom muaj kev nyab xeeb dua yuav ua kom muaj kev sib tw yav tom ntej ntawm cov roj nuclear Lavxias hauv kev lag luam thoob ntiaj teb."

Lub Koom Haum Tshawb Fawb Hauv Tebchaws ntawm Atomic Reactors (NIIAR) hauv Dimitrovgrad tam sim no tab tom ua ib qho kev tshawb fawb loj heev. kev simkev pab cuam ntawm MIR kev tshawb fawb reactor, suav nrog kev sim ntau yam khoom siv roj cladding thiab ATF roj pellets. Xyoo 2022, qhov kev pab cuam no tau nthuav dav kom suav nrog kev sim hauv-reactor ntawm cov roj tshiab nrog uranium silicide-based roj rau VVER thiab cov dej reactors siab. Txij li xyoo 2021, kev ua haujlwm sim ntawm peb lub rooj sib dhos roj sib xyaw nrog ATF roj rods tau ua tiav ntawm Rostov NPP's VVER-1000 reactor. Cov ntaub ntawv siv yog 42KhNM chromium-nickel alloy lossis chromium-plated zirconium alloy.
