He tokotoko whakakikorua-Kōromium kaha-teitei 42CrMo, he tokotoko whakakikorua-Kōromium mārō, he mea whakakikorua mō ngā taputapu mīhini.

Kua whakatūria e te Chepetsk Mechanical Plant (CMP), he wāhanga o te TVEL Fuel Division o te Rosatom State Corporation, he whare whakaputa whakamātautau mō whakakikorua wahie whakakikoruatia ki te chromiumHe otinga whai hua tēnei rauemi hanganga mō te hanga wahie matatau (AF) o te whakatupuranga e whai ake nei. Ka whakapai ake i te pono o te mahi a te wahie karihi, ā, ka whakarei ake i te haumaru me te whai huatanga o ngā tauhohenga.

Hei whakaputa i te whakakikoruatanga rakau wahie auaha, kua tonoa e ChMZ tētahi whare whakakikorua chromium mō te whakakikoruatanga koranu zirconium tuku iho. Ka pania tika te paninga tiaki ki ngā ngongo zirconium roa mā te whakamahi i te tikanga rehu. Hei tāpiri, kua tukuna ngā taputapu tātari me ngā taputapu rangahau hou hei aromatawai i te piri, te hanganga, me te matotoru o te paninga chromium, ka taea te whakamahi mō ngā kaupapa whakaputa me te rangahau i roto i te whakawhanaketanga o ngā hua hou. Kua hangaia he puranga whakamātautau o te whakakikorua rakau wahie whakakikoruatia ki te chromium.

I kī a Alexander Ugryumov, te Tumuaki Tuarua Matua mō ngā Mahi Pūtaiao me te Hangarau i TVEL: "Mai i te tau 2021, e toru ngā huihuinga wahie ATF kua whakatūria ki roto i ngā tauhohenga VVER-1000 o te Rostov NPP. Kei roto i ia huihuinga VVER-1000 e 312 ngā huānga wahie. Mā te whakatūnga o te tipu hanga huānga wahie whakakikoruatia ki te chromium ChMZ ka taea te whakaputa i ētahi huihuinga wahie ATF katoa. Mā te whakatūnga o ēnei huihuinga ki roto i ngā tauhohenga mana-teitei ka tohu i te wāhanga whakamutunga o te hanga wahie ATF ahumahi i Rūhia me te wāhanga whakatau me te whakatau whakamutunga."

I kī a Sergey Chineikin, te Kaiwhakahaere Matua o te Pokapū Tukatuka Anō i ngā Wahie Karihi o Rūhia, he mea tino nui ki te pokapū te whai wāhi atu ki te rangahau me te whakawhanake i ngā hangarau whakaputa wahie karihi hou. I kī ia, "Mā te whakaurunga o ngā taputapu ā-whare hou, hangarau-tiketike mō te paninga i ngā paninga tiaki ki ngā oko wahie me te whakaputa hua haumaru ake ka whakarite i te whakataetae a meake nei o te wahie karihi o Ruhia i te mākete o te ao."

Kei te whakahaerehia e te National Research Institute of Atomic Reactors (NIIAR) i Dimitrovgrad tētahi rangahau nui i tēnei wā. whakamātautaukaupapa i te tauhohenga rangahau MIR, tae atu ki te whakamātautau i ngā rauemi whakakikorua wahie me ngā pire wahie ATF. I te tau 2022, i whakawhānuihia tēnei kaupapa kia uru atu ki te whakamātautau i roto i te tauhohenga o ngā tokotoko wahie hou me te wahie e ahu mai ana i te uranium silicide mō te VVER me ngā tauhohenga wai pēhanga. Mai i te tau 2021, kua tīmata te whakahaere whakamātautau o ngā huihuinga wahie e toru me ngā tokotoko wahie ATF i te tauhohenga VVER-1000 o te Rostov NPP. Ko ngā rauemi hanganga e whakamahia ana he koranu chromium-nickel 42KhNM, he koranu zirconium whakakikoruatia rānei ki te chromium.

E whakaae ana ahau kia kohia e Verdict Media Limited ngā raraunga ka tukuna e au mā tēnei puka e ai ki tāna kaupapa here tūmataiti.
