I-42CrMo High-Strength Chromium-Plated Shaft Hard Hollow Chrome Plated Rod yezixhobo zoomatshini

2025-10-23

I-Chepetsk Mechanical Plant (CMP), eyinxalenye yeCandelo le-TVEL Fuel le-Rosatom State Corporation, iseke indawo yokuvelisa eyilinge ye- i-chrome-plated fuel claddingLe mpahla yokwakha sisisombululo esithembisayo sokuvelisa amafutha aphucukileyo esizukulwana esilandelayo (AF). Iphucula ukuthembeka kokusebenza kwamafutha enyukliya, ngaloo ndlela iphucula ukhuseleko kunye nokusebenza kakuhle kwee-reactors.

Ukuze kuveliswe ukugqunywa kwezinto ezintsha ze-fuel rod, i-ChMZ iqalise i-chromium-platting facility ye-zirconium alloy cladding yendabuko. Ingubo yokukhusela isetyenziswa ngqo kwiityhubhu ezinde ze-zirconium kusetyenziswa indlela yokutshiza. Ukongeza, izixhobo zanamhlanje zohlalutyo nezophando zinikwe umsebenzi wokuvavanya ukunamathela, ulwakhiwo, kunye nobukhulu bengubo ye-chromium, enokusetyenziselwa zombini iinjongo zemveliso kunye nophando ekuphuhlisweni kweemveliso ezintsha. Ibhetshi yovavanyo lwentonga yepetroli egqunywe nge-chromium-plated yenziwe.

U-Alexander Ugryumov, uSekela Mongameli oyiNtloko weMisebenzi yezeNzululwazi nezoBugcisa kwi-TVEL, uthe: "Ukususela ngo-2021, kuye kwaqaliswa ukuhlanganiswa kwepetroli ezintathu ze-ATF kwi-reactors ze-VVER-1000 zeRostov NPP. I-assembly nganye ye-VVER-1000 iqulethe izinto zepetroli ezingama-312. Ukuqaliswa kwesityalo sokuvelisa izinto zepetroli esine-chromium-plated ye-ChMZ kuya kuvumela ukuveliswa kweentlobo ezahlukeneyo zepetroli ze-ATF. Ukuqaliswa kwezi ndibano kwi-reactors ezinamandla aphezulu kuya kuphawula inqanaba lokugqibela lokuveliswa kwepetroli ye-ATF kwimizi-mveliso eRashiya kunye nenqanaba lokugqibela lokufaneleka kunye nokwenza izigqibo."

USergey Chineikin, uMlawuli Jikelele weZiko lokuHlaziya kwakhona iFuel yeNyukliya yaseRashiya, uthe ukuthatha inxaxheba kuphando nophuhliso lwetekhnoloji entsha yokuvelisa ifuel yenyukliya kubaluleke kakhulu kwiziko. Uqaphele, "Ukwaziswa kwezixhobo zasekhaya ezintsha, zobugcisa obuphezulu zokufaka iingubo zokukhusela kwiinqanawa zepetroli kunye nokuvelisa iimveliso ezikhuselekileyo kuya kuqinisekisa ukukhuphisana kwexesha elizayo kwepetroli yenyukliya yaseRashiya kwimarike yehlabathi."

I-National Research Institute of Atomic Reactors (NIIAR) eDimitrovgrad okwangoku iqhuba uphando olukhulu uvavanyoInkqubo yokuqhuba kwi-reactor yophando lwe-MIR, kuquka ukuvavanya izixhobo ezahlukeneyo zokufaka i-fuel cladding kunye nee-ATF fuel pellets. Ngo-2022, le nkqubo yandiswa ukuze ibandakanye uvavanyo lwe-in-reactor lwee-fuel rods ezintsha ezine-uranium silicide-based fuel ze-VVER kunye nee-pressurized water reactors. Ukusukela ngo-2021, ukusebenza kovavanyo lwe-fuel assemblies ezintathu ezidibeneyo kunye nee-fuel rods ze-ATF bekuqhubeka kwi-reactor ye-Rostov NPP ye-VVER-1000. Izinto zokwakha ezisetyenzisiweyo yi-42KhNM chromium-nickel alloy okanye i-chromium-plated zirconium alloy.

Ndiyavuma ukuba iVerdict Media Limited iqokelele idatha endiyinikayo ngale fomu ngokuhambelana nomgaqo-nkqubo wayo wabucala.
