Usha Dahaadhka ah ee 42CrMo ee Xoogga Sare leh ee Chromium-Plasted Usha Dahaadhka ah ee Qalabka Farsamada

Warshadda Farsamada ee Chepetsk (CMP), oo qayb ka ah Qaybta Shidaalka TVEL ee Shirkadda Gobolka Rosatom, ayaa samaysay xarun wax soo saar oo tijaabo ah dahaarka shidaalka ee chromium-platedQalabkan qaab-dhismeedka ah waa xal rajo leh oo loogu talagalay soo saarista shidaalka horumarsan ee jiilka soo socda (AF). Waxay hagaajisaa isku halaynta hawlgalka ee shidaalka nukliyeerka, taasoo kor u qaadaysa badbaadada iyo hufnaanta fal-celiyeyaashu.

Si loo soo saaro dahaarka usha shidaalka ee cusub, ChMZ waxay u xilsaartay xarun lagu dahaadho chromium oo loogu talagalay dahaarka dahaarka ee zirconium dhaqameed. Dahaarka ilaalinta waxaa si toos ah loogu mariyaa tuubooyinka dhaadheer ee zirconium iyadoo la adeegsanayo hab buufin ah. Intaa waxaa dheer, qalabka falanqaynta iyo cilmi-baarista casriga ah ayaa loo xilsaaray inay qiimeeyaan isku-dhejinta, qaab-dhismeedka, iyo dhumucda dahaarka chromium, kaas oo loo isticmaali karo ujeeddooyin wax soo saar iyo cilmi-baaris labadaba marka la samaynayo alaabada cusub. Dufcad tijaabo ah oo ah dahaarka usha shidaalka ee chromium-ka lagu dahaadhay ayaa la soo saaray.

Alexander Ugryumov, Madaxweyne Ku-xigeenka Sare ee Hawlaha Sayniska iyo Farsamada ee TVEL, ayaa xusay: "Tan iyo 2021, saddex qalab oo shidaal ATF ah ayaa laga hirgeliyay warshadda VVER-1000 ee Rostov NPP. Qalab kasta oo VVER-1000 ah wuxuu ka kooban yahay 312 walxood oo shidaal ah. Hawlgalka warshadda wax soo saarka shidaalka ee ChMZ chromium-ka lagu dahaadhay waxay suurtogalin doontaa soo saarista dhowr qalab oo dhammaystiran oo shidaal ATF ah. Hirgelinta qalabkan warshadda tamarta sare leh waxay calaamad u noqon doontaa marxaladda ugu dambeysa ee wax soo saarka shidaalka ATF ee warshadaha ee Ruushka iyo marxaladda ugu dambeysa ee u-qalmitaanka iyo go'aan qaadashada."

Sergey Chineikin, Agaasimaha Guud ee Xarunta Dib-u-habaynta Shidaalka Nukliyeerka ee Ruushka, ayaa sheegay in ka qaybgalka cilmi-baarista iyo horumarinta tiknoolajiyada cusub ee soo saarista shidaalka nukliyeerka ay muhiimad aasaasi ah u leedahay xarunta. Wuxuu xusay, "Soo bandhigidda qalab casri ah oo gudaha ah oo loogu talagalay in lagu daboolo dahaarka ilaalinta maraakiibta shidaalka iyo soo saarista alaabada amniga leh waxay hubin doontaa tartanka mustaqbalka ee shidaalka nukliyeerka Ruushka ee suuqa adduunka."

Machadka Cilmi-baarista Qaranka ee Fal-galka Atomiga (NIIAR) ee Dimitrovgrad ayaa hadda sameynaya baaritaan ballaaran tijaaboBarnaamijka sameynta ee fal-galka cilmi-baarista MIR, oo ay ku jiraan tijaabinta agab kala duwan oo lagu dahaadho shidaalka iyo walxaha shidaalka ee ATF. Sannadkii 2022, barnaamijkan waxaa la ballaariyay si loogu daro tijaabinta fal-galka ee ulaha shidaalka cusub oo leh shidaalka ku salaysan silikiska uranium ee VVER iyo fal-galayaasha biyaha ee cadaadiska lagu saaray. Tan iyo 2021, hawlgal tijaabo ah oo saddex isku-darka shidaalka ah oo isku-dhafan oo leh ulaha shidaalka ee ATF ayaa ka socday fal-galiyaha VVER-1000 ee Rostov NPP. Qalabka dhismaha ee la isticmaalay waa dahaarka chromium-nickel ee 42KhNM ama dahaarka zirconium ee chromium-plated.
