ʻO ke koʻokoʻo paʻakikī Chrome Hollow i uhi ʻia me ka Chromium ikaika kiʻekiʻe 42CrMo no nā lako hana
Ua hoʻokumu ka Chepetsk Mechanical Plant (CMP), he ʻāpana o ka TVEL Fuel Division o ka Rosatom State Corporation, i kahi hale hana hoʻāʻo no uhi wahie i uhi ʻia me ka chromiumHe hopena hoʻohiki kēia mea kūkulu no ka hana ʻana o ka wahie holomua (AF) o ka hanauna e hiki mai ana. Hoʻomaikaʻi ia i ka hilinaʻi hana o ka wahie nukelea, no laila e hoʻonui ana i ka palekana a me ka pono o nā reactors.
No ka hana ʻana i ka uhi ʻana o ke koʻokoʻo wahie hou, ua kauoha ʻo ChMZ i kahi hale hana chromium-plating no ka uhi ʻana i ka zirconium alloy kuʻuna. Hoʻopili pololei ʻia ka uhi pale i nā ʻōmole zirconium lōʻihi me ka hoʻohana ʻana i ke ʻano pīpī. Eia kekahi, ua kauoha ʻia nā lako loiloi a me nā lako noiʻi hou e loiloi i ka hoʻopili ʻana, ke ʻano, a me ka mānoanoa o ka uhi chromium, hiki ke hoʻohana ʻia no nā kumu hana a me nā noiʻi i ka hoʻomohala ʻana i nā huahana hou. Ua hana ʻia kahi pūʻulu hoʻāʻo o ka uhi ʻana i ke koʻokoʻo wahie i uhi ʻia me chromium.
Ua ʻōlelo ʻo Alexander Ugryumov, Hope Pelekikena Nui no nā Hana ʻEpekema a me nā Hana ʻenehana ma TVEL: "Mai ka makahiki 2021, ua kauoha ʻia ʻekolu mau ʻākoakoa wahie ATF ma nā reactors VVER-1000 o Rostov NPP. Loaʻa i kēlā me kēia ʻākoakoa VVER-1000 he 312 mau mea wahie. ʻO ke kauoha ʻana o ka hale hana hana mea wahie ChMZ chromium-plated e hiki ai ke hana i kekahi mau ʻākoakoa piha o ka wahie ATF. ʻO ke kauoha ʻana i kēia mau ʻākoakoa ma nā reactors mana kiʻekiʻe e hōʻailona i ka pae hope loa o ka hana wahie ATF ʻoihana ma Rusia a me ke kahua hōʻoia hope loa a me ka hoʻoholo ʻana."
Ua ʻōlelo ʻo Sergey Chineikin, Luna Hoʻokele Nui o ke Kikowaena Hana Hou ʻana i ka Wahie Nuklea o Rusia, he mea nui loa ke komo ʻana i ka noiʻi a me ka hoʻomohala ʻana i nā ʻenehana hana wahie nuklea hou i ke kikowaena. Ua ʻōlelo ʻo ia, "ʻO ka hoʻolauna ʻana i nā lako hana kūloko hou a kiʻekiʻe no ka hoʻopili ʻana i nā uhi pale i nā moku wahie a me ka hana ʻana i nā huahana palekana e hōʻoia i ka hoʻokūkū o ka wahie nukelea Lūkini ma ka mākeke honua."
Ke hana nei ka National Research Institute of Atomic Reactors (NIIAR) ma Dimitrovgrad i kahi noiʻi nui i kēia manawa. hoʻāʻopapahana hana ma ka reactor noiʻi MIR, me ka hoʻāʻo ʻana i nā mea uhi wahie like ʻole a me nā pellets wahie ATF. I ka makahiki 2022, ua hoʻonui ʻia kēia papahana e hoʻokomo i ka hoʻāʻo ʻana i loko o ka reactor o nā koʻokoʻo wahie hou me ka wahie uranium silicide-based no VVER a me nā reactors wai pressurized. Mai ka makahiki 2021, ua hoʻomaka ʻia ka hana hoʻāʻo o ʻekolu mau ʻaha hui wahie me nā koʻokoʻo wahie ATF ma ka reactor VVER-1000 o Rostov NPP. ʻO nā mea hana i hoʻohana ʻia he 42KhNM chromium-nickel alloy a i ʻole chromium-plated zirconium alloy.
Ke ʻae nei au iā Verdict Media Limited e hōʻiliʻili i ka ʻikepili aʻu e hāʻawi ai ma o kēia palapala e like me kāna kulekele pilikino.
